Only Hot Water Extracts Are:

  • 100% Used in Traditional Herbalism
  • 100% Used in The Clinical Research
  • Proven Effective for Therapeutic Use

There are 1,000's of studies proving the effectiveness of hot water extracts (liquid and dehydrated). There is NOT EVEN ONE independent study verifying the effectiveness of un-extracted mycelium bio-mass or un-extracted mushrooms for immune health. Which product would you bet your life on?


Why a Hot Water Extract?

Hot Water Extraction

Hot water extraction is the most expensive and technically the most difficult method used to manufacture supplements from medicinal fungi. However, it is also the only scientifically validated method of delivering the needed potency and bio-availability for immune related conditions.

Hot water extraction is recommended in:
  • 100% of the scientific research on medicinal fungi for cancer and immune related conditions.
  • 100% of the references in the texts on Traditional Chinese Medicine

Surprisingly, given this powerful consensus, the need for hot water extraction is ignored by the authors of popular books and articles on medicinal mushrooms. Studies using hot water extracts represent 100% of the cited references for medicinal fungi and immune health in the three most recent books on medicinal mushrooms, yet none of the authors make this crucial point within the text of their books.

Unfortunately, the vast majority of medicinal mushroom supplements sold on the U.S. market are un-extracted mushrooms or un-extracted mycelium, products that have no supporting research for immune health issues.


Mushrooms are unique, stationary like a plant, yet built from chitin, the same material contained in the shell of a lobster. Understanding the properties of chitin is critical to understanding how to choose an effective, high-quality medicinal mushroom product.

Chitin is indigestible by humans.(1) Yet chitin, which makes up the cell walls of mushrooms and mushroom mycelium, contains the potent immune stimulating compounds common to all medicinal mushrooms, the polysaccharides.(2) Practitioners of Traditional East Asian Medicine and modern clinical researchers both use the same preparation technique to overcome this barrier, hot water.

Only a heated liquid solution can break down the indigestible chitin and release the active compounds into a concentrated, bio-available form.3 When used in Traditional Chinese Medicine for chronic conditions or immune health medicinal mushrooms are always prepared with heat and water, as a tea or a decoction. (4,5,6,7,8)

Medicinal mushrooms are never used in the un-extracted form (as mycelium bio-mass powder or dried mushroom powder), and rarely prepared as a tincture (soaked in alcohol and water in the absence of heat).

Scientific research backs this traditional preparation method. Every published, independent study on the use of medicinal mushrooms for immune health has been conducted with a hot water or hot water/alcohol extract. Every form of extraction, including precipitation with alcohol, requires a heated liquid solution to first release the polysaccharides, the primary active compounds, from the chitinous cell walls of the mushroom and mushroom mycelium.(9)

This is true for Reishi;(10,11) Coriolus versicolor;(12,13) Maitake;(14) Shiitake;(15,16) and Cordyceps.(17) All of the well-known isolates are also extracted in a heated aqueous solution, including Maitake Fraction from Maitake, PSK and PSP from Coriolus versicolor, and Lentinan and LEM from Shiitake.

According to the American Herbal Pharmacopoeia mycelium bio-mass products are inferior because of a "lack of bio-availability". This publication also states that concentrates derived through proper extraction contain active compounds "magnitudes higher than what is available in crude mycelium biomass preparations".(18)

At JHS Natural Products we take these lessons seriously. Our dehydrated hot water extracts are formulated to deliver all of the important constituents unique to each mushroom. Every batch is analyzed for purity, contains guaranteed amounts of the active compounds, and is offered as a pure extract, containing no mycelium bio-mass or ground mushrooms as filler.
