In traditional Chinese medicine and in many of the studies of medicinal mushrooms, hot water extracts have been used. The cell wall of the mushroom is indigestible by humans—hence, eating raw mushrooms either as food or as medicine is not recommended. Ground mushroom eaten as a powder is irritating to the liver, yet when that ground mushroom is decocted in hot water, the medicinal ingredients become available and it is safer to consume. As a result, several integrative oncology clinicians report that they prescribe hot water extracts of medicinal mushrooms.1McKinney N. Naturopathic Oncology, 3rd Edition. Victoria, BC, Canada: Liaison Press. 2016. p. 228.

Expert commentary

In a 2008 article, naturopathic oncologist and CancerChoices advisor Leanna Standish, PhD, ND, LAc, FABNO, and her colleagues suggest that “immune therapy utilizing the polysaccharide constituents of Trametes versicolor as concurrent adjuvant cancer therapy may be warranted as part of a comprehensive [breast] cancer treatment and secondary prevention strategy.”2Standish LJ, Wenner CA et al. Trametes versicolor mushroom immune therapy in breast cancer. Journal of the Society for Integrative Oncology. 2008 Summer;6(3):122-8.

In Life Over Cancer, integrative physician and CancerChoices advisor Keith Block, MD, advises: “It is difficult to obtain clinically meaningful quantities of the mushroom phytochemicals from even the healthiest diet, which is why I recommend getting them in the form of extracts. Look for those containing maitake (Grifola frondosa), agaricus (Agaricus blazei), shiitake (Lentinula or Lentinus edodes), reishi (Ganoderma lusidum), turkey tails (Trametes or Coriolus versicolor), and caterpillar fungus or cordyceps (Cordyceps sinensis).”3Block KI. Life over Cancer: The Block Center Program for Integrative Cancer Treatment. New York: Bantam Dell. 2009. p. 114. He further advises using extracts that are blends of several different medicinal mushrooms, including turkey tail.

Paul Stamets, in MycoMedicinals, says this about using a blend of several different medicinal mushrooms: “A number of researchers have come to the conclusion that, to maximize a host-mediated response—that is, to awaken the immune system—a panoply of polysaccharides and medicinal mushroom constituents is best. These constituents increase the number and activity of macrophages, killer T and NK lymphocytes. Combining medicinal mushroom species sends the immune system multiple stimuli, awakening the body’s natural defenses.”4Stamets P. MycoMedicinals: An Informational Treatise on Mushrooms, 3rd Edition. China: MycoMedia Productions. 2002. p. 68.

Naturopathic oncologist and CancerChoices advisor Lise Alschuler, ND, FABNO, August 9, 2018: There are instances when I use specific mushrooms, for instance: Coriolus (aka Trametes) versicolor (turkey tail) for breast cancer, Agaricus blazeii for ovarian cancer and chaga mushroom for melanoma. However, it is a very valuable and reasonable strategy to use a blend that includes mushrooms, each of which is standardized to its polysaccharides and beta-glucans. The key is to use a hot water extract of the fruiting bodies or a full-spectrum extract (includes mycelium) that clearly identifies on its label the quantity of mushroom extract.

Some blends that I often recommend:

Per capsule:

  • Trametes versicolor (turkey tail) (40% polysaccharides, 40% beta-glucans)–100mg
  • Grifola frondosa (maitake) 40% polysaccharides, 30% beta-glucans–100mg
  • Ganoderma lucidum (reishi), 40% polysaccharides, 15% beta-glucans–100mg
  • Lentinula edodes (shiitake), 409% polysaccharides, 40% beta-glucans–100mg

I would recommend between 2–3 capsules twice daily.

When recommending single mushrooms, it is important to know how much beta-glucan is in each serving so that I can titrate my dose accordingly. For instance, I often use Grifola frondosa m(aitake) mushroom to increase white blood cell counts. One product I use contains (per 6 tablets):

  • Maitake (Grifola frondosa) Fruiting body powder–600mg
  • Maitake fruiting body extract, standardized to contain 30% D-fraction–240mg (so 72mg D-fraction beta glucan)
  • Vitamin C 120mg (supports bioactivity)

Cost permitting, in most clinical studies, the daily dose of mushroom extracts that is correlated with improved survival (especially in breast, colorectal, gastric cancers) is 3000mg/day.
