Lion’s Mane: a Psychosomatic Psychobiotic

I know you immediately think of the brain, but follow the vagus nerve from brain to gut and let’s just stay there for a while…

This mushroom is incredibly popular right now. Very hip. Very trendy.

Also of grand popularity are afflictions of the stomach, intestines and the colon. Many people have a visceral response to this overstimulating existence of modernity, and the most common viscera affected – the gut. Not only is the entire weight of the world living there, but the once-prolific community of microorganisms that once inhabited this space, and that would normally support the gut with the physiological burden that comes with this weight, has been significantly depleted. The reasons for this lack of microbial support are many, though we can just call it an unhealthy obsession with purity. The problem here is that this physiological burden that comes with the stress of the world, more often than not, becomes a pathology. Lion’s Mane extracts infiltrate the gut and the associated lymphoid tissue, regulating inflammation, decreasing oxidative damage, feeding the residing microbiota and modulating the immune system – all desired actions for healing, and hopefully avoiding, this potential pathology. Before being known as a nootropic medicinal, this mushroom was used in Traditional Chinese Medicine as a digestive tonic and to support gastrointestinal health. I have gone through the most current research to support the use of Lion’s Mane for gut health, and so overall human health.

Warning – most all of the research has been done on rats or mice. This is just the reality of most in vivo research and that is all we get until human clinical studies, which are incredibly difficult to find funding for – especially with natural products that don’t have potential to be synthesized into pharmaceuticals – can be done. So if you need to blame someone, blame capitalism and big pharma.

Rodent studies exploring Hericium Extracts and inflammatory bowel disease (IBD)

There have been many studies exploring variations of Lion’s Mane extracts and the effects of these extracts on rodents with chemically induced inflammatory bowel disease (I know it is fucked up). In one study1, mice were exposed to 2% dextran sulfate sodium (DSS) for 7 days to induce acute intestinal inflammation. These mice were then administered an ethanol extract of Hericium at a dose of 250mg/kg/day (This is a very big dose). Results showed that the treated mice had significant improvement in body weight, colon length and overall decreased intestinal bleeding compared with control mice. After administration of the extract, there was suppressed production of inflammatory mediators (TNF-alpha, IL-1â and IL-6) in colon tissue, as well as a decrease in oxidative damage potentiators (nitric oxide production, malondialdehyde, and superoxide dismutase). Overall, Lion’s Mane decreased inflammation and oxidative stress, leading to a decrease in mucosal damage and protection of mucosal epithelium.

Another in vivo study2 induced colitis in mice using this same DSS solution, and found similar results with Hericium polysaccharides.  In this study, researchers tested markers of inflammation and oxidative stress before and after administration of the polysaccharides. Similar to the previously described study, there was a marked improvement in clinical symptoms postulated to be due to the decrease in nitric oxide, malondialdehyde, superoxide dismutase and myeloperoxidase. There was also a significant reduction in inflammatory cytokines TNF alpha, IL-1ß, and IL-6. Other notable markers decreased after polysaccharide administration include COX-2 and iNOS. COX-2 is an important enzyme in the prostaglandin synthesis pathway and the target of NSAIDs (like aspirin). Reduction or inhibition of this enzyme leads to decreased pain and inflammation. Intriguingly, this extract also blocked phosphorylation of NF-kappaB, p56 and also reversed DSS- induced gut dysbiosis and maintained intestinal barrier integrity. NF-kappaB is the major transcription factor for inflammatory cytokine production and if it is not phosphorylated it will not be active, and so less overall inflammation. (I realize I am really driving home the idea that we want to reduce inflammation, and inflammation is NOT always bad, but in a condition like inflammatory bowel disease, where the inflammation is causing significant damage to the mucosa and destroying a person’s quality of life, inflammation is not desirable).

Another method of inducing colitis in rats is with a trinitrobenzene sulfonic acid (TNBS) enema. To further explore the therapeutic potential of various Hericium extracts on inflammatory bowel disease, another study3 had to be done, using rats with this TNBS induced colitis. After the TNBS enema, the rats exhibited symptoms of reduced activity, lethargy, weight loss, ruffled fur, and bloody stool. After 14 days of Lion’s Mane extract treatments, there was significant improvement in all symptoms. Serum levels of inflammation were also monitored during this time, and decreased significantly after treatment. The proportion of FOXP3 and IL-10 positive cells significantly increased, especially in the rats receiving the alcoholic extracts compared with the model group. FOXP3 is the transcription factor for T-regulatory cells, and T regulatory cells secrete IL-10, so increased levels indicate improved immune regulation.

Prebiotic activity: Another study4 using an IBD rat model explored immunomodulatory activity of the water soluble fungal protein, HEP3, extracted from the mushroom fruiting body. The mechanism proposed: regulation of the gut microbiota. The study explained that HEP3 is a protein, and its digestion and absorption is reliant on proteases and peptidases extracted from bacteria. The nitrogenous degradation products of protein digestion also serve as important nutrient and energy sources for some anaerobic organisms. Knowing this, HEP3 can significantly influence the diversity, structures, and metabolism of organisms and microorganisms. Evidence suggests that the diversity of gut microbiota is reduced in IBD patients, so finding treatments that can target both inflammation and increase biodiversity is ideal. In this study, after HEP3 administration, Bifidobacterium abundance increased significantly and the colon tissue damage, inflammation, other prebiotics and diversity and structures improved significantly. Bifidobacterium is a beneficial genus of bacteria, associated with enhanced gut health and overall human health. This study concluded that HEP3 improves the immune system via regulation of the structure and metabolism of gut microbiota. The researchers postulate that through this prebiotic role, HEP3 activates the proliferation and differentiation of T cells and stimulates antigen presenting cells.

This prebiotic activity was also found in a hot water extract of the fruiting body.5 The preparation method was to simmer dried and ground mushroom in water (1:10, w:v) for 8 hours followed by pouring ETOH over the extract and leaving overnight. The alcohol was used to precipitate the polysaccharides which were then collected and used as the treatment in question. This method of precipitating polysaccharides out with alcohol is typically how polysaccharides are extracted in a laboratory setting, and so when people say that alcohol will destroy the polysaccharides in your mushroom extract, that is simply not true. This study found that Lactobacillus plantarum was the probiotic most affected by the Hericium polysaccharides. At first, after administration of the polysaccharides, the bacterial population rapidly increased after 6h. Also, the molecular weight of the polysaccharide decreased due to the loss of glycosidic bonds from gastrointestinal digestion, leading researchers to suppose that digestion is vital for the bioactivity of these polysaccharides in the GI system.

 Immune modulation: Not only are these polysaccharides food for our gut bacteria, but they are also the primary constituent involved with immune modulation. There are many receptors in the phagocytes associated with mucosal immunity and the most often discussed regarding mushroom 𝛃-glucans is Dectin-1. Interestingly, one study6 found evidence that that the major pattern recognition receptors for Hericium polysaccharides are TLR2 and mannose receptor rather than Dectin-1. (fangfang wu 2017) In an in vivo mouse study assessing Hericium polysaccharides and their effect on cell mediated immunity (T-cells and phagocytes), humoral immunity (B-cells, complement and antimicrobial peptides), phagocytic capacity of peritoneal cavity phagocytes, and NK cell activity, results showed that Hericium polysaccharides improve immune function by functional enhancement of all of the above.

Neuroimmunity: mucosal immunity and vagus nerve regulation

The vagus nerve, the 10th cranial nerve and the queen of the parasympathetic response. This is the rest and digest, the chill and feel, the relax and pass response. The Vagus nerve also innervates the majority of our digestive organs, hence the ‘digest’ and ‘pass’ parts of the aforementioned idioms. Therefore, the mucosal immunity described previously, is also innervated by this nerve. Studies show that when vagus is dysfunctional, there is more GI inflammation and an overall dysregulated mucosal immunity.7,8 There is evidence for stress-induced alterations in gut flora and an associated increase in inflammatory markers in the gastrointestinal tract. Does it go both ways? If there is less stress, then there is less GI inflammation, but if there is more regulation of gut inflammation, increased intestinal integrity and a more diverse microbiome, will there be a more regulated stress response? Are we stimulating vagus by stimulating mucosal immunity, therefore eliciting a parasympathetic response? Is this actually the mechanism by which Lion’s Mane decreases depression and anxiety in post-menopausal women?9

Bidirectional gut-brain communication: One route of this communication is thought to begin through sensory information from the GI tract, and subsequent activation of neural, hormonal, and immunological signals. These signals can independently or cooperatively relay information to the central nervous system (CNS).10,11,12 There are a number of studies described in this review regarding increased probiotic intake associated with increased mood and less anxiousness. Specifically, probiotic supplementation with Lactobacillus helveticus and Bifidobacterium longum showed less self-reported negative mood and decreased urinary cortisol.13 A similar effect was also observed in healthy participants who consumed a mixture of Bifidobacterium bifidum and Bifidobacterium lactis, and Lactobacillus acidophilus, Brevibacillus brevis, Brevibacterium casei, Bifidobacterium salivarius, and Lactococcus lactis 14 Allen et al.15 found that healthy individuals fed Bifidobacterium longum had attenuated levels of cortisol and reduced subjective anxiety in response to the socially evaluated cold stress pressor test.  It does indeed seem to go both ways: decreasing inflammation and regulating the gut microbiome reduces anxiety and stress, and reduced anxiety and stress decreases inflammation and regulates the gut microbiome.

Lion’s Mane mushroom is more than one constituent that increases nerve growth factor synthase (the myopia of this mushroom’s medicine). Lion’s Mane, like all things living, is made up of many synergistic compounds that work together to keep this mushroom living and producing. These compounds also happen to play a major role in human health. This field of neuroimmunology is growing and the physiological effects of Lion’s Mane are an excellent example of the mechanisms of bidirectional gut-brain communication. Lion’s Mane is, in fact, the ultimate psychosomatic medicine, in the true meaning of the word – relating to the interaction of mind and body, the psyche and the soma, and a true psychobiotic.

*Psychobiotic is actually a word, I did not invent it. It is a medicine that affects the psyche by regulating the gut microbiome.

Fall Transitions

Fall. The quintessential season of the mushroom. I very outwardly and not so secretly love when summer comes to an end. The giant ball of fire in the sky, reflecting off of the far too many reflective surfaces throughout the city like laser beams in a diamond shop, is finally going to be shrouded by clouds. What a treat. Although a creature of habit, I have a deep love for transition – seasons of transition, symbols of transition, momentous occasions initiating transition, etc. Perhaps this is why I love Fall, and perhaps this is why I have a tattoo of an ouroboros on my right arm, and most definitely why I love mushrooms. As the rains come and wash away the summer, this can be a time of deep introspection and with that, inevitable discomfort. Shorter days and a generally darker existence is not desirable to most people, but can be especially valuable for the psyche. So rather than seeking herbs or mushrooms to bring more ‘light’ during this time, how about seeking out plant and mushroom allies to support and encourage transition. I think of deciduous trees during this time, trees that innately hold the energy of transformation – the ability to move through seasons in different forms and continue to grow stronger each year. The tannins in the leaves of the Birch, Willow, Poplar and Aspen oxidize from green to brilliant yellow, red, and brown. They stand bare through winter – vulnerable, nude, yet with tremendous stature and strength. Imaginably, this is the medicine that these trees share, and the energy that we can cultivate. Look for patterns in nature to understand the medicine in nature.  Is it grace through transition that you desire? Look closer at the natural world that surrounds you. This grace encompasses you already.

 

Oyster Mushroom

Pleurotus ostreatus

“side of the body” and “resembling oyster” 

I am apt to write about the polypores – the often overlooked wizened and ancient ‘conks’ of the forest –  that require more time to age, to collect, to process. I am stepping back and writing about the medicine of the familiar gilled Oyster Mushroom. They are as common in the forest as in the grocery store, and what better medicine to write about than medicine that is so accessible that the forest dwellers as well as the grocery store goers may benefit.

The fruiting Oysters will be found on hardwoods mostly – the Cottonwoods, Oaks and Alder – fruiting from their carnivorous mycelia in the spring. The carnivory is real – watch the mycelia digest a nematode in this video

Pleurotus ostreatus

Spore print

White

Known active constituents

Pleuran (polysaccharide), chrysin, ergothioneine, lovastatin, GABA

Nutritional information

Nutritional constituents estimated per 100 g dry weight include protein (29.3 g), carbohydrate (62.97 g), crude fat (0.91 g), ash (6.82 g) and crude fiber (12.3 g).

Energy value of this mushroom was about 297.5 kcal/100 g dry weight

Major mineral components estimated include Ca, Fe, and Mg with highest level of 505.0, 109.5 and 108.7 mg/100 g respectively.

Therapeutic actions

Immune modulating, antiatherogenic, neuroprotective, antioxidant, inflammation modulating

 Some laboratory findings

Antiatherogenic

There are many factors that aggregate and result in atherosclerosis. These include and are not limited to hypertension, hyperglycemia, hypercholesterolemia and lipid peroxidation. Oyster mushroom research has demonstrated protection against all of those factors. In an animal study, rats were administered chrysin-rich Pleurotus extract. After administration there was a significant decrease in mean blood serum levels of glucose, lipid profile parameters, and hepatic marker enzymes and a simultaneous increase in enzymatic and nonenzymatic antioxidant parameters.2

 P. ostreatus is the richest known source of ergothioneine, containing 118.91mg/kg. As mentioned previously, ergothioneine protects against DNA damage and lipid oxidation. For hypertension, Oyster mushroom water extract inhibits angiotensin converting enzyme (ACE) – a common mechanism in hypertensive medication.

Oyster mushroom also contains lovastatin, a naturally occurring statin compound that reduces LDL cholesterol through inhibition of HMG-CoA reductase.

Some human findings

Atopic dermatitis

In a split-body study of 80 patients, topical P. ostreatus-based β-glucan cream application resulted in improvement of both subjective and objective symptoms of atopic dermatitis. The patients applied the cream on one segment of the body with atopic dermatitis and no treatment on another atopic dermatitis segment. On the application site there was a significant decrease in the number of days and severity of atopic dermatitis. 4

You can make your own Oyster mushroom cream by following my mushroom cream recipe hereThe aqueous part of the cream will be an Oyster mushroom decoction.

Respiratory Disease

Pleuran extract from Oyster mushrooms has clinical evidence for application with various respiratory diseases. In a human study, chronic obstructive pulmonary disease (COPD) patients treated with 100mg Pleuran, 60mg vitamin C, and 5mg Zinc, had significantly lower incidence and shorter duration of exacerbations compared to the control (60mg vitamin C and 5mg Zinc).5

In another double-blinded, placebo-controlled, randomized multicentric study, 175 children were treated with either pleuran or placebo over a 12-month period. Children treated with pleuran experienced a significant reduction in the frequency of recurrent respiratory tract infections. 1,6 These findings agreed with a Spanish study investigating 166 children aged one to ten years old who were also treated with Pleuran for recurrent respiratory infection.7

Advantageous respiratory effects of pleuran were also observed in adult athletes. A study included 50 athletes treated with pleuran over a three month period of time and found a significant reduction in the frequency of upper respiratory tract infections as compared to athletes treated with placebo. Blood samples of the athletes showed significantly higher levels of circulating NK cells in the pleuran group as compared to the placebo group.8

Antihyperlipidemic

20 subjects were randomized to take either one portion of soup containing 30g dried oyster mushrooms or a tomato soup (placebo) on a daily basis for 21 days. Standardized blood concentrations of lipid parameters and oxidized LDLs were measured at baseline and after 21 days. Treatment with Oyster mushroom soup decreased both triacylglycerol and oxidized low density lipoprotein levels significantly, and showed a significant tendency towards lowering total cholesterol values. 9

Pleurotus ostreatus Syrup Recipe

for upper respiratory support

Ingredients

30g dried Oyster mushrooms, chopped

120mL raw honey

130mL Water (up to 300mL if not using pressure cooker)

Kitchen Tools Needed

Boiling pot or Pressure cooker (Instant pot)

Cheese cloth

Potato ricer

Bowl

Directions

Pressure cooker: pressure cook dried mushrooms with 130mL water for 45 minutes

Boiling pot: boil for 1.5 hours, strain mushroom from decoction, dispose of mushrooms, put aqueous extract back on heat and reduce liquid down to 120mL

Once you have 120mL of mushroom aqueous extract, stir in 120mL of raw honey

Store in jar and refrigerate

Final product should be 240mL 1:8 (1gram of mushroom in 8mL liquid)

1g mushroom =  about .5g Pleuran

Some math:

Pleurotus ostreatus is about 50% Polysaccharide, and the best way to extract these polysaccharides is through a boiling process. We have 30g of dried Pleurotus ostreatus and for a child who weighs 27kg, we would dose them with 270mg Pleuran, and so about 540mg dried oyster mushroom, or .5g. We want there to be .5g in 1 tsp (4mL) of extract. Since we will add 1part honey to 1part mushroom decoction, we will want the decoction to be a 1:4 and the final product to be a 1:8.

Pediatric Dose: 4mL (~.25g Pleuran)

Including Mushrooms in your Daily Life: Recipe 1

It is easy enough to read and write about the research that has been done on medicinal mushrooms, but what is one supposed to do with this new found knowledge? What if you don’t have time to make a dual extract, or it feels too hot out to drink a hot mushroom tea. There are many ways to include mushrooms into daily life that do not involve imbibing a tea or taking a tincture. As it is now Fall and the weather will start to get colder, people are more susceptible to viruses. A person who uses mushrooms throughout their days will be more resilient during these cooler and darker months, and really, the whole year. The medicinal polypore mushrooms that I usually write about are deemed ‘inedible’ in most ID books. To an extent, this is true, in that you are not going to fry them up and eat them like a Shitake or Matsutake, but there are definitely ways to consume them, and benefit from their medicinal qualities. This is the first recipe I’ll be posting, but stay tuned for more throughout the next few months.

Immune Boosting Oatmeal

oats

Beta-Glucans Galore!

For 1 large Serving

Ingredients

1/2 C Oatsrei

1 C Water or pre-made *Mushroom decoction

1 Tbs Mushroom powder (Reishi, Chaga, Cordyceps, Turkey Tail, Lion’s Maine) – available at Dandelionbotanical.com

1/2 tsp Cinnamon

1/2 tsp vanilla extract

1 tsp Turmeric

1 Tbs maple syrup, honey, or mushroom infused honey! (made by chopping up polypore mushroom into the smallest pieces possible, filling up a jar half way, pouring raw honey over the mushrooms, and letting sit for 1 month or more)

Instructions

  1. Place all ingredients accept sweetener in pot over high heat. When boiling begins, turn down heat to a simmer.
  2. let simmer for a few minutes until oats are fully cooked and then drizzle maple syrup or honey.
  3. Add fruit, seeds, nuts, milk, yogurt, whatever you love!
  4. Enjoy and know you are keeping your immune system strong and healthy.

*Mushroom decoction: 1 Handful chopped mushrooms placed in pot or crockpot. Pour 4 cups of water over mushrooms, and simmer until the brew is decocted by half…this means that there will now be 2 cups left. You can test this by using a chopstick – Mark the chopstick where the water begins, and then dip the chopstick in intermittently to see when the brew hits half – Strain out the mushrooms and either drink the decoction as tea, or place in fridge for use in smoothies, oatmeal, broths, porridge, rice, beans, and stews.

A note on beta-glucans and the Immune System

Fungal Cell Wall Components

gunal

“Chitin, Chitinase Responses, and Invasive Fungal Infections : Figure 1.”Chitin, Chitinase Responses, and Invasive Fungal Infections : Figure 1. N.p., n.d. Web. 14 May 2015. http://www.hindawi.com/journals/ijmicro/2012/920459/fig1/

Beta Glucans are polysaccharides (carbohydrates) found in the cell walls of Yeast, Fungi, Algae, Lichens, and some plants, such as Oats and Barley. Together, with Chitin, they make up the fungal cell wall. B-glucans are biological response modifiers. This means that they cause no harm and place no additional stress on the body while helping the body to adapt to certain biological and environmental stressors. They support major systems such as the nervous, hormonal and immune system. You may have heard of adaptogens, this is a very similar definition.

Research shows that Beta-glucans have a hypoglycemic, cholesterol lowering, immune-stimulating and immune-modulating, and anti-tumor effect on animals. 1,2,4

Beta-glucans are made up of hemicellulose, which is a soluble fiber. Soluble fiber is water-soluble and forms a viscous water layer in the gut. This viscous layer in the small intestine decreases absorption of sugars and lipids into the blood stream. (hence, the hypoglycemic and hypocholesterolemic effect). Beta glucans from fungi reduced overall level of cholesterol and LDL in blood, as well as decreased the level of free fatty acids, while at the same time increasing HDL cholesterol. The sugars also increase the amount of Leptin – a protein like substance produced by fat cells that plays a role in hunger and satiety, which suggests their use as an agent to help with weight loss.

Beta-glucans are resistant to stomach acid and so they move through the GI, into the small intestines pretty much unchanged. The cells in the lining of the small intestine, the enterocytes, facilitate the transportation of the Beta-glucans into the lymph where the macrophages are waiting with open arms (Dectin-1 receptor sites). Like a key, they unlock the macrophages and activate them to travel back to the lymph nodes to induce immune activations. Once activated, it starts to produce bactericidal compounds such as reactive oxygen radical, N-oxide, and lysozyme. These activated cells also produce cytokines, which then activate phagocytes and leukocytes in specific immunity. B-glucans also play a role in promoting the activity of helper lymphocytes known as Th1 and Th2. Th1 controls immunity against intracellular parasites, while Th2 controls immunity against extracellular pathogens. When there is an imbalance in these lymphocytes, an autoimmune response can occur. Beta glucans help keep this balance.

Antitumor action: The antitumor action happens via activation of the immune response, explained earlier. They do not attack cancer cells directly, but produce their antitumor effects by activating different immune responses in the host. They potentiate the response of precursor T cells and macrophages to cytokines produced by lymphocytes after specific recognition of tumor cells. In summary, the tumor cells are attacked by the immune system, which is activated by macrophages bound with Beta glucans.

The Snow Flower

Sarcodes Sanguinae

(Resembling Flesh, Blood Red)

Snow Plant or Snow Flower

Family: Ericaceae (Madrone family) Sub-Family: Monotropoideae (Indian Pipe family)

The Snow Flower. Back in the day, when it still snowed in Tahoe, and the pine-needled humus would have a layer of snow in the Spring, I would look forward to this brilliant red being that would erect from the earth surface. The snow is mild now, but this crimson beauty still comes up, yet the contrast against the white of the snow is missed. A fitting plant to talk about on this blog being that although it is a plant, it is a saprophytic plant, getting its nutrients from the mycorrhizal fungi rather than partaking in photosynthesis, as green leaved plants do. The Snow Flower is most often seen near conifers, Ponderosa Pine, Jefferey Pine, Sugar Pine, etc. It is found here because it can’t live without them – a very one-sided and secretive connection. It is not directly parasitic to the tree, but it feeds on the trees relationship with mycorrhizal fungi. The fungi and the conifer have a mutualistic relationship; the fungus provides minerals and other earthly delights for the tree, while the tree provides sugars for the fungus – the Snow flower then gets it’s nutrients from this fungi.

John Muir writes of Sarcodes in 1912:

“The snow plant is more admired by tourists than any other in California. It is red, fleshy and watery and looks like a gigantic asparagus shoot. Soon after the snow is off the ground it rises through the dead needles and humus in the pine and fir woods like a bright glowing pillar of fire. In a week or so it grows to a height of eight or twelve inches with a diameter of an inch and a half or two inches ,then its long fringed bracts curl aside, allowing the twenty or thirty five lobed, bell-shaped flowers to pen and look straight out from the axis. It is said to grow up through the snow on the contrary, it always waits until the ground is warm, though with other early flowers it is occasionally buried or half buried for a day or two by spring storms. The entire plant-flowers, bracts, stems, scales, and roots-is fiery red. Its color could appeal to one’s blood. Nevertheless, it is a singularly cold and unsympathetic plant. Everybody admires it as a wonderful curiosity, but nobody loves it as lilies, violets, roses, daisies are loved. Without fragrance it stands beneath the pines and firs lonely and silent, as if unacquainted with any other plant in the world; never moving the wildest storms; rigid as if lifeless, through covered with beautiful rosy flowers.”

In the New York Medical Eclectic, Volume 6, Issue 10 (1879):

“The Sow Plant, a Flower of Strange Beauty.

One of the Grandest objects which meets the eye of the traveler in our mountains is the exquisite plant, the Snow Plant of the Sierras-the Sarcodes sanguinea of John Torrey, the botanist. It is an inhabitant only to the higher Sierras, being rarely found below an altitude of 4,000 feet, and its glorious crimson spike of flowers may be seen early in May, forcing itself through the snows which at that period cling about the sides of our pine forests. The portion of this plant which is visible above the soil is bright rosy crimson in color and presents the very strongest contrast to the dark green of the pines shimmer of the snow. Its root is succulent, thick, and abundantly free of moisture, attaching itself to the roots of other plants, principally to the species of the pine family…the Deer are exquisitely fond of it, and it is not an uncommon circumstance to find a number of the plants uprooted and robbed of the fleshy part of their underground growth…”

Food and Medicine

I have always been told, since I was a child, to not mess with the Snow Flower. I never knew why exactly, in fact I thought maybe it was poisonous. The real reason is that it only grows around the Sierras and it is a rare and protected plant – although I will talk about its history of use as food and medicine, it would be wise to pocket this information for your own edification and choose a different plant for these uses, that is not as rare.

The Snow Flower, is in fact edible and can be cooked like asparagus.

I can deduce from the ethnobotanical uses that it has an analgesic effect as well as soothing epithelial tissues. There is documentation of a decoction of the leaves and stem to treat ulcerated sores, irritated skin, and toothaches. The docterine of signatures would suggest its use as a blood tonic, and a decoction has been used in this way. Some Native Americans also dried and powdered this plant to relieve toothaches and other mouth pains.

How to Make Amadou Mushroom Felt

Fomes fomentarius

(Tinder, Used for Tinder)

Tinder polypore, False tinder polypore, Amadou, Iceman fungus, Hoof fungus, Hoof Conk, Tsuriganetabe

Distribution

Where there is Birch, there is F. fomentarius. North-Eastern United States, Alaska, Northern Mainland Europe. Found on Hardwoods.

There is usually only one or two fruiting bodies found per tree. It is a perennial, parasitic mushroom. Each layer of tubing represents a new year of growth. The thin crust is striped with various shades of grey, while the flesh is dark golden-brown, and the pore surface is pale grey to white. The flesh of the fruiting body is also known as the trauma layer. It is this trauma layer that is used as a natural gauze, tinder, and amadou felt.

Ethnobotanical Uses

Amadou, derived from a Northern French dialect, meaning “amorous”, or “inflames life”. This meaning is exemplified in the mushrooms historical use as tinder. This word also translates to the english word, spunk, meaning courage, bravery or determination, originally meant spark. (Spunk is a combination of spark and funk). Interestingly, the fungal essence is used for the burnt out artist, to help them get their spark back.

A 5000 year old Iceman, Otzi, was found with this polypore. In 1991 hikers found his preserved remains in a glacier in the Otzal Alps between Austria and Italy. It is thought that he was carrying this mushroom to preserve fire, use as insect repellent, and as his first aid kit.

The name, Fomes fomentarius means, “to use as tinder”. It is extremely flammable, but has a nice slow burn, perfect for long travels through the mountains. Additionally, and a perk for the insect-loved traveler, the smoke produced by the burning of this mushroom works as an excellent insect repellent. In addition to flame and insect deterrent, this mushroom is a powerful hemostat.

There is documentation of Hippocrates using F. fomentarius as a styptic in the fifth century BC. Also used as a styptic by surgeons, barbers and dentists, giving it the name “agaric of the surgeons”.  There is also note of the Okanagan-Olville native Americans using this as a styptic, a wound dressing, and a cauterizing agent. They would place a piece of the softened amadou layer over the affected area and ignite. This amadou layer was also used as a wound dressing and styptic throughout Europe. In a German speaking Alpine area in Europe, where this mushroom was called Wundschwamm, F. fomentarius was sold in pharmacies in the form of styptic bandages. While carving the mushroom’s crust off to expose this styptic layer of amadou, I sliced my finger with a serrated knife and there was heavy bleeding. I quickly wrapped a piece of the amadou around my finger. My finger stopped bleeding within minutes, and the amadou stayed on my finger as a nice bandage.

This mushroom was also used in ritual smoking ceremonies, in Germany and Austria, and by the Khanty people in West Siberia. They would burn the fruiting bodies to obtain smoke when a person died. The smoke would burn as to avoid any influence of the deceased on the living. This smoke has also been used similar to moxibustion. The ignited mushroom is placed over different parts of the body to warm the meridians, helping with the movement of blood and qi.

Currently studied as a treatment for esophagus, gastric and uterine carcinoma. Recent research shows distinct antibiotic activity against Bacillus subtillis and staphylococcus aureus with antifungal activity against Aspergillus flavus.

Also, anti-inflammatory and analgesic activities have been documented.

Cross Section of F. fomentarius
Materials

Sharp serrated carving knife

Cutting board

Hammer, ideally wide headed, like a Leatherman’s hammer

Hammering surface

Washing Soda Solution (sodium carbonate)

Instructions
  1. Cut off the crust of the mushroom

IMG_0089IMG_0090

This is done carefully with a sharp knife, serrated works well. You want to be careful here to not cut off too much of the trauma layer.

  1. Cut the off the tubes*

IMG_0092IMG_0094

This is done by making deep cuts in the tubes and then cracking them apart, and peeling them away from the trauma layer, careful to not peel too much of the trauma layer off with them. Remaining tubes can be cut away with a knife.

3. Soak trauma layer over night to a week in washing soda solution, or boil for at least 20 minutes

IMG_0098

  1. Pound damp trauma layer

IMG_0099

5. Soak again, pound again, and repeat until desired thickness reached.

6. Let the amadou felt (trauma layer) dry out, and use, as you like!

IMG_0100

 

Don’t throw away the mushroom parts that have been removed from the trauma layer. Simmer these in water and drink as an immune boosting tea, or use the tubes as a candlewick.
