also called as Lingzhi in China, Reishi in Japan and Youngchi in Korea.

Reishi mushrooms grow wild on decaying logs and tree stumps in the coastal provinces of China. Reishi mushroom
grows in six different colors, but the red reishi is the popular.  Reishi has been shown to have benefits on variuos
conditions such as general fatigue and weakness, asthma, insomnia, and cough for thousand years. Reishi's Chinese
name ling zhi means the herb of spiritual potency.  Reishi contains sterols, coumarin, mannitol, polysaccharides, and
triterpenoids [ganoderic acids].

Reishi mushroom benefits with scientific evidence

Reishi Benefits - Antioxidative activities
Reishi mushroom extract demonstrated anti-oxidative activities against heart toxicity in mice in a dose-dependent
manner [1] .

Reishi Benefits - Immunocompetence
Reishi mushroom was safe to horses with respect to the CBC and blood biochemistry data after the reishi dosing.
Reishi mushroom increased the percentage of CD5+, CD4+ and CD8+ T-lymphocytes and the amount of specific
antibody production in horses. [2] A fraction (F3) of a reishi polysaccharide extract was shown to activate the
expression of IL-1, IL-6, IL-12, IFN-gamma, TNF-alpha, GM-CSF, G-CSF and M-CSF. [3]
 

Reishi Benefits - Blood pressure, LDL and Coronary artery disease
Ganoderic acids (of reishi mushroom) may lower blood pressure and LDL (the bad cholesterol}. These specific
triterpenoids may also help reduce blood platelets from sticking together -an important factor in lowering the risk for
coronary artery disease. Two controlled clinical trials have shown that reishi mushroom could lower high blood pressure
significantly .  [Note. The people with hypertension in the second study had previously not responded to medications,
though these were continued during the study.] [4-6]

Reishi Benefits - Altitude sickness and Hepatitis B
Reishi mushroom may have some efficacy in treating altitude sickness and chronic hepatitis B. [7]  

Reishi Benefits - Glomerulosclerosis
Reishi mushroom may suppress endothelial cell cytotoxicity and proteinuria in 14 patients of glomerulosclerosis. [8]

Reishi Benefits - Diabetes Mellitus
Reishi may have some benefits for people suffered from diabetes mellitus. [9] Zhang HN and Lin ZB, Peking University,
Beijing, investigated the hypoglycemic effect of reishi mushroom polysaccharides in the normal fasted mice and the
possible mechanism. They found that reishi mushroom extract could lower the glucose level in a dose-dependent
manner however the reishi extract had no effect on islets insulin content. [10]

Reishi Benefits - Cancer
Reishi mushroom has been shown to have potiential benefits on the treatment or prevention of certain cancers.  
Reshishi mushroom has demonstrated anticancer activities in experiments with cancer cells. [11]

A Japanese research group extracted triterpene acid, lucidenic acid P (1a), and two triterpene acid methyl esters,
methyl lucidenates P (1b) and Q (2b) from the fruiting body of the reishi mushroom. All of the compounds from reishi
extracted showed potent inhibitory effects on Epstein-Barr virus early antigen induction (96-100% inhibition at 1 x 10(3)
mol ratio/TPA). [12]
 

Colon cancer Hong KJ et al, Texas Tech University, found that reishi mushroom extract causes no cytotoxicity in human
colon carcinoma HT-29 cells at doses less than 10000 microg/ml. Increasing concentrations of reishi extract reduced
prostaglandin E2 production, but increased nitric oxide production. Together with other data, reishi extract has been
shown to have pro-apoptotic and anti-inflammatory functions, as well as inhibitory effects on cytokine expression during
early inflammation in colonic carcinoma cells. [13]

Breast Cancer Reishi mushroom (ganoderma lucidum) inhibited proliferation of breast cancer MDA-MB-231 cells by
downregulating Akt/NF-kappaB signaling. [14]
 

Prostate Cancer Reishi mushroom inhibits cell proliferation in a dose- and time-dependent manner by the
down-regulation of expression of cyclin B and Cdc2 and by the up-regulation of p21 expression for the human prostate
caner cells PC-3. The reishi inhibition of the cancer cell growth was also demonstrated by cell cycle arrest at G2/M
phase. [15]

Reishi Benefits - Ulcer
New Zealead researchers observed the anti-ulcer activities of reishi mushroom on the rat. They extracted the
water-soluble polysaccharide from reishi mushroom (ganoderma lucidum) and inhibited the indomethacin-induced
gastric mucosal lesions successfully in rats with the reishi extracts. [16]

DOSE
Reishi can be taken either as 1.5 grams per day of the crude dried mushroom, 1-1.5 grams per day in powdered
form.[17]
