Concentrated Mushroom Extract

Creating a concentrated tar

– with a dose of just a mL- potent, shelf-stable, alcohol free medicine-

A 5:1 concentrated extract or sometimes called a solid extract simply means there is an equivalent of 5 grams of original substance per 1 mL of final liquid extract

I love these concentrated mushroom extracts, yet it is important to note that these do not replace dual (aqueous and ethanolic) extracts. In the process I will describe below, lipophilic constituents like Triterpenes will likely not occur in the final concentrate.

What will be extracted:

Water soluble constituents that are not destroyed by heat. In the case of mushrooms, specifically Fomitopsis pinicola, Trametes versicolor, and Ganoderma applanatum, which are the mushrooms in this extract, we are extracting; immune-stimulating, immune-modulating, hypoglycemic, and hypocholesterolemic polysaccharides and anti-oxidant phenolic compounds.

What you will need for this preparation:

Mushrooms: at least 300g

Water: enough to cover the mushrooms by a few inches

Crockpot or soup pot

Stove top or hot plate

Beaker to measure mL of liquid

Honey – enough to equal the final amount of liquid in the extract – if starting with 300g of mushrooms, and we are aiming for a 10:1 extract, we need 30mL honey to add, to get a 5:1.


  1. Collect mushrooms or purchase dried mushrooms from your local  herb shop, slice thin and dry over night

2. Get the dry weight of the mushrooms in grams, then place mushrooms in crockpot or large soup pot and cover with water – so water covers by a few inches

3. let Simmer for a minimum of 2 hours, if using a crockpot it is great to simmer overnight

643g polypores simmering

4. Press out mushrooms from decoction – compost mushrooms, or pour 100 proof vodka over them to extract triterpenes. – if you do this let it mushrooms macerate in ETOH for 2 weeks

5. Place aqueous extract (decocted liquid)  in smaller soup pot and let simmer – this is where you want to keep a close eye on the process, stirring somewhere in between occasionally to avoid over simmering and burning

6. Simmer down until there is 30mL of extract (if you started with 300g) – the idea is that you have an equivalent of 10g dried mushroom material for every 1mL liquid. – 10:1

10:1 64mL of concentrate

7. Take off the heat and add an equal amount of honey – if there is 30mL of extract, you will add 30mL of raw honey and mix thoroughly, now you have a 5:1 concentrated syrup.

Raw Honey added, now 5:1

Place in amber jars – Refrigeration is unnecessary-

  1. Hello Brittany!! it is springtime here in British Columbia, Canada. I have just finished drying turkey tail mushroom and now have them in a crockpot on low. I had approx. 300 gr. fresh. I sliced thinly and dried over night. I covered the mushrooms with water till fully submerged which is hard because they float!!! I will move on to step 4 tomorrow.


  2. I just found this site. It is really, really good. Full of honest info instead of pushing a product. I am a member of several mushroom groups and have used this site as a link because of the quality of it. Great job!!!


  3. Hello, first I just want to say that I admire your work greatly and appreciate all the information you share! I wanted to know your thoughts on the triterpenoids contained within certain medicinal Mushrooms. I know that the type of beta glucans they contain aren’t volatile to heat but are the triterpenoids? Will they be denatured by the heat? Thank you!!!


    1. Thank you for reaching out and thank you for your kind words! Triterpenes contained in mushrooms are usually if the lanostane triterpenes glycoside variety. Triterpenes are higher molecular weight compounds and are not volatile. They are also not destroyed by heat.
