Reishi [Lingzhi, Ganoderma lucidum] mushroom is a popular
supplement with an impressive array of reputed health benefits.
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].
HEALTH BENEFITS AND SIDE EFFECTS OF REISHI; RESEARCH
FINDS
Antioxidative activities
Reishi [Ganoderma Lucidum] mushroom extract demonstrated anti-
oxidative activities against heart toxicity in mice in a dose-dependent
manner. [Wong KL et al Antioxidant activity of ganoderma lucidum (reishi) in acute
ethanol-induced heart toxicity. Phytother Res. 2004 Dec;18(12):1024-6.]
Immunocompetence
Reishi was safe to horses with respect to the CBC and blood
biochemistry data after the reishi dosing. Reishi (ganoderma
lucidum) increased the percentage of CD5+, CD4+ and CD8+ T-
lymphocytes and the amount of specific antibody production in
horses. [Lai SW et al, Influence of ganoderma lucidum on blood biochemistry and
immunocompetence in horses. Am J Chin Med. 2004;32(6):931-40.]
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. [Chen HS et al, Studies on the immuno-modulating
and anti-tumor activities of Ganoderma lucidum (Reishi) polysaccharides. Bioorg Med
Chem. 2004 Nov 1;12(21):5595-601]
Blood pressure, LDL and Coronary artery disease
Ganoderic acids (of reishi) 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 could lower high blood pressure significantly . [The
people with hypertension in the second study had previously not responded to medications,
though these were continued during the study. Kammatsuse K, Kajiware N, Hayashi K.

to Asian Traditional Medicine. New York: Elsevier Science, 1996, 131–8.]
Altitude sickness and Hepatitis B
Reishi may have some efficacy in treating altitude sickness and
chronic hepatitis B. [Hobbs C. Medicinal Mushrooms. Santa Cruz, CA: Botanica Press,
1995, 96–107]
Glomerulosclerosis
Reishi [ganoderma lucidum] may suppress endothelial cell
cytotoxicity and proteinuria in 14 patients of glomerulosclerosis.Futrakul
N et al, Ganoderma lucidum suppresses endothelial cell cytotoxicity and proteinuria in
persistent proteinuric focal segmental glomerulosclerosis (FSGS) nephrosis, Clin Hemorheol
Microcirc. 2004;31(4):267-72.
Diabetes Mellitus
Reishi may have some benefits for people suffered from diabetes
mellitus. [Jones K. Reishi mushroom: Ancient medicine in modern times. Alt Compl Ther
1998;4:256–66 [review].]
Zhang HN and Lin ZB, Peking University, Beijing, investigated the hypoglycemic
effect of Ganoderma lucidum polysaccharides (reishi extract) in the normal
fasted mice and the possible mechanism. They found that reishi extract could
lower the glucose level in a dose-dependent manner however the reishi extract
had no effect on islets insulin content. [Zhang HN et al, Hypoglycemic effect of
Ganoderma lucidum polysaccharides, Acta Pharmacol Sin. 2004 Feb;25(2):191-5]
Cancer
Reishi has been shown to have potiential benefits on the treatment
or prevention of certain cancers. Reshishi has demonstrated
anticancer activities in experiments with cancer cells. [Sliva D, Methodist
Research Institute, IN, Ganoderma Lucidum (Reishi) in cancer treatment, Integr Cancer
Ther. 2003 Dec;2(4):358-64.]
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 fungus Ganoderma
lucidum (reishi). 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). [Lucidenic acids P and Q,
methyl lucidenate P, and other triterpenoids from the fungus Ganoderma lucidum (reishi)
and their inhibitory effects on Epstein-Barr virus activation. J Nat Prod. 2003 Dec;66(12):
1582-5]
Colon cancer Hong KJ et al, Texas Tech University, found that reishi
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. [Effects of Ganoderma lucidum on
apoptotic and anti-inflammatory function in HT-29 human colonic carcinoma cells.
Phytother Res. 2004 Sep;18(9):768-70.]
Breast Cancer Reishi (ganoderma lucidum) inhibited proliferation of
breast cancer MDA-MB-231 cells by downregulating Akt/NF-kappaB
signaling. [Jiang J et al,Ganoderma lucidum suppresses growth of breast cancer cells
through the inhibition of Akt/NF-kappaB signaling. Nutr Cancer. 2004;49(2):209-16.]
Prostate Cancer Reishi 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.
[Jiang J et al, Ganoderma lucidum inhibits proliferation and induces apoptosis in human
prostate cancer cells PC-3, Int J Oncol. 2004 May;24(5):1093-9]
Ulcer
New Zealead researchers observed the anti-ulcer activities of reishi
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. [Gao Y et al, Ganoderma lucidum polysaccharide fractions
accelerate healing of acetic acid0induced ulcers in rates. J Med Food. 2004 Winter;7(4):
417-21]

How do other web-site publishers describe reishi?
Reishi (Ganoderma) is a magical herbal medicine from the
Mysterious East. Reishi Ganoderma is the highest grade of
mushroom in the world of fungi. For centuries, the Chinese regard it
as "The King of All Herbs" [Unicitypinoy, May 13, 2005]
Wild Reishi is extremely rare. Only a small quantity of reishi can be
found on a hill. Due to damage by insects and weather, the quality of
wild Reishi is unpredictable. And, the dried mushrooms may not have
the potency of the fresh mushroom. [coffee-reishi.blogspot.com, May
15, 2005]
Ganoderma lucidum is the scientific name for Red Mushrooms, and is
said to be more powerful than Ginseng. Known as the "Miraculous
King of Herbs", it is called Lingzhi in China; Reishi in Japan and
Youngchi in Korea. [kayted.com/gano, May 15, 2005]
