• Fu Ling (Poria cocos)
• Yun Zhi (Coriolus versicolor)
• Ling Zhi (Ganoderma lucidum Reishi)
• Bai Mu Er (Tremella fuciformis Snow Fungus).
All classified as Superior Herbs, defined as having excellent
therapeutic action, few or no side effects, may safely be
taken for long periods and of which it is said that ‘prolonged
use will lighten the body and confer longevity’!
• In a 15 year study of 174,505 inhabitants of the Nagano area of Japan,
mushroom farmers were found to have a much lower rate of death
from cancer than the general population (97.1/100,000 cf.
160.1/100,000).1
• An epidemiological study of 2,000 Chinese women, half with breast
cancer and half without, found a reduction in risk of breast cancer in
those women who regularly consumed mushrooms (10g/day fresh or
4g/day dried) and drank green tea (1.05g/day dried green tea leaves)
with an increased reduction in women who did both. 2
• Two Korean studies comparing women with histologically confirmed
breast cancer and an equal number of women without breast cancer
also found a strong inverse correlation between mushroom
consumption and breast cancer risk. 3

• In a systematic review and meta-analysis aggregating and analyzing the
efficacy of Coriolus exracts on survival of cancer patients from 13
randomized, placebo-controlled clinical trials, Coriolus was found to
result in a significant survival advantage compared with standard
conventional anti-cancer treatment alone.
• Of patients randomized to Coriolus, there was a 9% absolute reduction
in 5-year mortality, resulting in one additional patient alive for every 11
patients treated. In patients with breast cancer, gastric cancer, or
colorectal cancer treated with chemotherapy, the effects of the
combination of Coriolus preparation on the overall 5-year survival rate
was more evident, but not in esophageal cancer and nasophayngeal
carcinoma.
• Subgroup analysis could not conclude which type of anti-cancer
treatment may maximize the benefit from Coriolus.

in cancer patients: systematic review and meta-analysis. Recent Pat Inflamm
Allergy Drug Discov. 2012 Jan;6(1):78-87.
MD Anderson Cancer Centre’s Detailed Scientific
Review of Coriolus
• ‘Coriolus is a promising candidate for chemoprevention due to the
multiple effects on the malignant process, limited side effects and
safety of daily oral doses for extended periods of time.’
• PSK and PSP seem to work at multiple steps of the malignant
process by inhibiting adhesion, invasion, motility, and metastatic
growth of tumor cells in animal models of cancer.
• Adhesion and invasion are inhibited by suppression of cell matrixdegrading enzyme production by malignant cells.
• Motility of malignant cells and subsequent attachment to blood
vessels are inhibited by suppression of tumor-cell induced platelet
aggregation and anti-angiogenic factors.

• Immune responsiveness of the host does not appear to be affected by
PSK under normal conditions, but immune systems depressed by
tumor-burden or chemotherapy, have reportedly been restored to
normal levels by PSK in animal studies.
• Immune restoration has included antibody and cytokine production and
improvement of impaired antitumor activity of natural killer cells, T
cells, macrophages and peripheral blood lymphocytes in vivo and in
vitro.
• PSK has also been demonstrated to inhibit the decline of
immunocompetence during the perioperative period and inhibit the
growth of residual tumors following cryoablation.
• PSP has also been shown to reverse tumor-induced immunodeficiencies
in sarcoma-bearing mice by increasing immunoglobulin G and C3
complement levels. It has also been associated with increases in white
blood cell count, CD4, CD8, B-lymphocytes, and neutrophils, along with
a higher survival rate of tumor bearing mice.
Toxicology of PSK
• PSK has been associated with side effects of gastrointestinal upset and
darkening of the fingernails, but these effects have been limited and
general safety has been demonstrated with daily oral doses for
extended periods of time. It does not seem to interact with hepatic
drug-metabolizing enzymes involved in the chemical processing of
most chemotherapy agents, and no genetic damage has been detected
by the Ames test.
• At doses that produced necrotic changes in tumor cells, PSP produced
no lesions in the vital organs of tumor-bearing mice after treatment for
two months. It has not been associated with teratogenic effects in mice
or rats.
• 1994 Gastric cancer trial by the Nakazato and Koike of the Study Group
for Immuno-chemotherapy reported in the Lancet (1994;343:11221126) concluded that no toxic effects could be observed from PSK
“even after meticulous review of all the patient records”.
Lentinan
From Lentinula edodes
(Shiitake)
Meta-analysis of 5 clinical trials with a total of 650
participants showed that the addition of lentinan at
2mg/week to standard chemotherapy offers a significant
advantage over chemotherapy alone in terms of survival
for patients with advanced gastric cancer, with patients
with lymph node metastasis having slightly better results
than those with non-lymph node metastasis . 1

M, Matsui T, Kodera Y, Sakamoto J. Anticancer Res. 2009 Jul;29(7):2739-45.
• Additional trials confirm increased survival, reduced side
effects from chemotherapy and improved quality of life in
patients with colorectal, hepatocellular, breast cancer and
metastatic prostate cancer. In a trial with 69 patients with
metastatic prostate cancer the 50% survival length of
treated and control patients was 48 and 35 months,
respectively while the the five-year survival rate of treated
patients was 43% against 29% in the control group1,2.
• Although usually delivered by injection, Lentinan is also
orally bioavailable although the clinical dosage is likely to be
significantly higher 3,4.

Hen of the Woods
D-fraction / MD-fraction
In a non-randomised study of 165 patients with stage III-IV
cancer given Maitake D-fraction with Maitake fruiting body
tumour regression and/or significant symptomatic
improvement was seen in 66% of lung cancer patients, 54%
of liver cancer patients, 56% of pancreatic cancer patients
and 74% of breast cancer patients1.

• In a separate study a combination of MD-fraction and
whole Maitake fruiting body powder was reported to
produce similar improvements: 58.3% of liver cancer
patients, 68.8% of breast cancer patients and 62.5% of
lung cancer patients1.
• In vivo studies also showed synergy between D-fraction
and chemotherapy (mitomycin C) as well as significant
alleviation of side effects from chemotherapy, including
loss of appetite, vomiting, nausea, hair loss and
leukopenia2.

Agaricus subrufescens
(Agaricus blazei / brasiliensis)
Almond Mushroom
• A. blazei polysaccharide extracts show strong in-vitro and in-vivo activity
against a range of cancer cell lines, including: lung and ovarian cancer1.
• Clinical studies are limited although Mizuno reports positive clinical
results in a number of mainly breast cancer patients at unspecified
dosage while Ahn reports increased NK-cell activity and reduced
chemotherapy related side effects from A. blazei polysaccharide
extract2.
• A 2008 study confirms increases in NK cell activity with A. blazei
polysaccharide extract a dose of 3g/day3.

1-3, 1-6-Beta Glucan
Lentinan - a polysaccharide isolated from Shiitake
and licensed in Japan as a pharmaceutical drug.
Heteropolysaccharides – as well as Glucose mushroom polysaccharides
typically contain other sugars, such as Mannose, Galactose, Xylose, Fucose,
e.g.:
• Xylogalactoglucan – Inonotus obliquus (Chaga)
• Glucomannan – Agaricus blazei
• Galactoglucomannan – Lentinus edodes (Shiitake)
• Mannogalactofucan – Grifola frondosa (Maitake)
• Galactoxyloglucan – Hericium erinaceous (Lion’s Mane)
• Glucoronoxylomannans – Tremella fuciformis (Snow Fungus)
Although most research has focussed on β Glucans, especially β-1,3 and β-1,4
linked, α-1,4 and α-1,6 glucans have also shown anti-tumour activity

PSK (Krestin) and PSP from Trametes versicolor
• PSK is a a purified hot-water extract consisting of proteinbound polysaccharide molecules with an average
molecular weight of 94kDa.
• Protein component ranges from 25-38%.
• The main constituent monosaccharide is glucose wıth
small amounts of other sugar residues, such as mannose,
fucose, xylose and galactose. The main chain consists of
beta 1-4 linked units with side chains of beta 1-3 as well as
beta 1-6 linked glucose residues.
• PSP is similar to PSK but differs in the presence of
rhamnose and arabinose.

Consequences of a TH1 - TH2 Shift
• Lowered resistance to viral and other pathogens.
• Increases in fatigue and incidence of depression.
• Increases incidence of allergic and auto-immune conditions
such as asthma and SLE.
• Persistent humoral immune responses exacerbate
recruitment and activation of innate immune cells in
neoplastic microenvironments where they regulate tissue
remodelling, pro-angiogenic and pro-survival pathways that
together potentiate cancer development.1

Dectin-1
• Commonly expressed in macrophages, neutrophil lineages,
dendritic cells and some T-cells but not NK-cells.
• Considered the most important receptor for the activation
of the innate immune response in macrophages.
• Binds specifically to β-(1→3)-glucans but only those
consisting of at least 10 monomers
• Binding activates phagocytosis, ROS production and
induction of TNF-α, IL-2, IL-10, IL-12

CR3
• Expressed mainly on Neutrophils, Monocytes and NK
Cells.
• Two binding sites exist on the CD11b domain. One for βglucans and the other for iC3b (cleaved component 3
fragment of serum complement system).
• Binding of β-glucans to CR3 increases adhesion to
microbial cells and activates the iC3b pathway causing
tumour cytotoxicity.

Mushrooms and Chemotherapy
• Lentinan extended survival and reduced the incidence of
adverse effects in inoperable or recurrent gastric cancer in
conjunction with tegafur as well as S-1-based
chemotherapy (tegafur, gimeracil, oteracil).
• Five-year disease free survival in colorectal cancer cases
was significantly higher with PSK and oral Tegafur/Uracil
(UFT) than with UFT alone (73% vs. 58.8%) and increased
five-year disease-free period (70.7% vs. 59.4%) and
survival (73.0% vs. 60.0%) in gastric cancer when given
together with mitomycin and fluoracil.
• Agaricus subrufescens polysaccharide extract reduced
chemotherapy related side effects (appetite, alopecia,
emotional stability, and general weakness) in 100 cervical,
ovarian, and endometrial cancer patients treated either
with carboplatin plus VP16 (etoposide) or with carboplatin
plus taxol.
• Grifola frondosa polysaccharide fractions potentiated the
action of carmustine and increased efficacy when given in
combination with chemotherapy across a range of cancers,
as well as reducing cisplatin-induced nephrotoxicity.
In addition to supporting the immune system and ameliorating
chemotherapy-induced immune suppression there is some
evidence that mushroom polysaccharide extracts contribute to
the efficacy of the chemotherapeutic drugs themselves through
enhanced production of reactive oxygen species (ROS):
• Liu et al reported an increase in ROS and reactive nitrogen
intermediates in peritoneal macrophages of mice given PSP.
• An extract of A. subrufescens was shown to induce apoptosis
through an ROS-dependent pathway.
• Grifron-D, a polysaccharide extract from G. frondosa, has
been shown to have a direct cytotoxic effect on cancer cells
through oxidative membrane damage leading to apoptosis.
Mushrooms and Radiotherapy
• Reduction in radiation-induced leukopaenia - in a trial with
136 patients undergoing radiotherapy, oral consumption of T.
fuciformis polysaccharide extract (3g/day) resulted in a 13.2%
reduction inWBC compared to a 35.2% reduction in the
control group and T.versicolor mycelial biomass (6g/day)
prevented decreases in red and white blood cells in lung
cancer patients undergoing radiotherapy.
• Enhanced treatment efficacy - oral administration of
T.versicolor extract PSP with radiotherapy significantly
increased the percentage of apoptotic cells at 24hr compared
to radiation alone and reduced radiotherapy induced
reduction in white blood cell count.
Mushrooms’ Prebiotic Activity
Recent research indicates that mushroom polysaccharides
have a prebiotic effect on the gut microbiome with
increases in Bifidobacterium and Lactobacillus species and
decreases in Clostridium, Staphylococcus and Enterococcus
species, together with increased concentration of organic
acids (lactate and short-chain fatty acids), decreased pH
and increased β-galactosidase and β-glucosidase activity
and it has been suggested that this effect may also
contribute to their diverse health benefits1,2.

CORIOLUS SUPPLEMENTATION FOR LSIL
A 1 year controlled trial using Coriolus versicolor mycelial
biomass in 43 LSIL HPV patients reported results including:
• Cytology returned to normal in 72.5% of patients
receiving Coriolus supplementation (3g/day) compared
to 47.5% in the control group.
• 90% of patients who received supplementation
became –ve for High Risk HPV strains compared to
8.5% in the control group.

Widely used as a folk medicine in Russia
and eastern europe to treat cancer and
support the immune system. Credited
with curing Solzhenitzen of cancer.
Contains high levels of betulinic acid
(also one of the key components in
mistletoe) derived from the bark of host
birch trees, with actions including:
•
•
•
•
Anti-retroviral
Anti-malarial
Anti-inflammatory
Anti-cancer
Betulinic Acid and Cancer
• Induces mitochondrial apoptosis in different cancer cell lines
and inhibits the enzyme topoisomerase, which is essential for
the unwinding and winding of the DNA strands in cell
replication.
• In-vitro studies on betulinic acid have shown it to be highly
effective against a wide variety of cancer cells: human
melanoma, neuroectodermal (neuroblastoma,
medulloblastoma, Ewing's sarcoma) and malignant brain
tumors, ovarian carcinoma, human leukemia HL-60 cells and
malignant head and neck squamous cell carcinomas, including
those derived from therapy-resistant and refractory tumors.

• Betulinic acid's action against brain tumor cells is particularly
interesting and it is noteworthy that in one study it exerted
cytotoxic activity against primary tumor cells cultured from
patients in 4 of 4 medulloblastoma-tumor samples tested and
in 20 of 24 glioblastoma-tumor samples.
• It also shows great promise in combination with radiotherapy,
exhibiting a strictly additive mode of growth inhibition in
combination with radiation in human melanoma cells in one
study and acting as a radiosensitizer in head and neck

Cordyceps
Ophiocordyceps sinensis
/ Cordyceps militaris
• Anti-fatigue – Cordyceps has been shown to increase endurance,
efficiency of oxygen utilization and cellular ATP levels. In a trial with 50
asthma patients 81.3% showed improvement with an average of 5 days
using Cordyceps compared to 61.1% taking antihistamines with an
average of 9 days for symptoms to subside.
• Hepato-protective – inhibits hepatic fibrogenesis derived from chronic
liver injury, retards the development of cirrhosis, reduces liver enzyme
levels and significantly improves liver function.
• Anti-cholesterol – decreases plasma cholesterol in rats fed a
cholesterol enriched diet and increases ratio of HDL to LDL.
• Anti-stress – equivalent to ginseng. Counteracted inhibition of weight
gain, increase in adrenal gland weight, increase in glucocorticoid
receptors in the liver, spleen and thymus and increased peroxidation in
the liver and heart.
• Immuno-modulatory and anti-cancer – activates macrophages,
stimulates bone marrow cell proliferation through activation of Peyer’s
patch cells.

Current Issues
• Lack of standardisation
• Different formats:
• Fruiting body
• Mycelium
• Hot-water extracts (polysaccharide-rich)
• Ethanolic extracts (triterpene-rich)
• Mycelial biomass (rich in anti-microbial secondary
metabolites and substrate-breakdown products
such as arabinoxylans but low in beta-glucans and
related polysaccharides)
• Lack of comparative research
• Single mushrooms vs. combinations
