Le Ganoderma lucidum (connue également sous les noms communs Lingzhi ou Reishi) est un champignon médicinal très recherché en Chine depuis plus de deux mille ans pour son large éventail de vertus médicinales. Cette herbe précieuse était réservée, il y a très longtemps de cela, aux rois, aux reines et aux nobles. Ses propriétés médicinales furent mentionnées pour la première fois dans le plus ancien registre chinois de plantes médicinales, le « Shen Nong Ben Cao Jing », et furent décrites dans le plus éminent ouvrage de référence de plantes médicinales chinoises, le « Ben Cao Gang Mu » de Li Shin-chen en 1578. Grâce aux avancées des technologies scientifiques modernes et à la prise de conscience accrue dans le monde occidental, des recherches intensives menées dans de nombreuses universités de renommée internationale ont prouvé de manière continue la valeur nutritionnelle et l’efficacité des utilisations traditionnelles du Ganoderma lucidum.
Au cours des 40 dernières années, de nombreuses recherches sur le Ganoderma lucidum ont été réalisées aux États-Unis, au Canada, au Japon, à Taiwan, en Chine, etc. Il a été révélé que le Ganoderma lucidum était particulièrement indiqué pour les personnes désirant un complément alimentaire de qualité supérieure pour une vie saine:
- Renforcement du système immunitaire (immuno-modulation)
- Maintien d’une bonne santé et prévention du vieillissement
- Amélioration du métabolisme
- Stimulation de la fonction de désintoxication du foie et des reins
- Atténuation des réponses hypersensibles (allergie)
- Amélioration des problèmes de santé chroniques, tels que l’hypertension, le diabète, etc. par l’effet de complément alimentaire

Reishi extract appears to be extremely helpful for
cancer patient therapy. For example, they may be used to eliminate
suppression of immunity during post-operation therapy or to prevent
side effects of anti-tumor therapy. (V. Kupin, Cancer Research Centre
AMS Russia, Moscow, Russia)
Reishi extract exhibits a marked immunomodulating
effect, increasing T-cell counts, and the CD4/CD8 ratio, it also
had immune enhancement effect, or the effect of Reishi-induced bio-regulation.
Reishi administration in cancer patients with initially decreased
immunologic indices led to an increased number of T-lymphocytes,
and T-helper cells and lower levels of T-suppressors. In patients
with initially normal indices it had a negligible effect. (V. Kupin,
Cancer Research Centre AMS Russia, Moscow, Russia)
Reishi reduced chemotherapy-induced toxicity as well
as that induced by radiotherapy. Chemo- and radiotherapy-induced
leukopenia was soon eliminated after Reishi administration. Patients
could tolerate chemotherapy much better against the background of
Reishi, their T-lymphocyte levels and CD4/CD8 ratio restored rapidly.
(V. Kupin, Cancer Research Centre AMS Russia, Moscow, Russia)
No side effects had been observed in patients receiving
reishi extract. On the contrary, they had improved appetite, exhibited
more vigor and noted a better general status. Post-operation patients
receiving reishi extract noted normalized hemodynamic indices within
a shorter time interval and developed no complications as compared
to patients not receiving reishi extract. The operation wound healed
better, the recovery period after surgery was shorter. (V. Kupin,
Cancer Research Centre AMS Russia, Moscow, Russia)
Polysaccharides from the Reishi are used in Japan
as immuno-potentiators in the treatment of cancer. Reishi extract
is usually combined with other types of therapies, such as radiation,
surgery and chemotherapies, to increase the effectiveness, reduce
the side effects and accelerate recovery from disease. (Dr. Morishige,
M.D. Ph.D, surgeon and member of the Linus Pauling Institute of
Science and Medicine)
Reishi extract has been investigated and found to
have broad stimulatory effect on white blood cells including leukocytes,
monocytes, macrophages, Natural Killer cells, LAK cells, TIL cells,
and other lymphocytes. This effect accounts for anti-viral, anti-tumor,
anti-inflammatory effects. Such potential effects and low toxicity
make reishi extract particularly attractive for immune support of
patients undergoing radiotherapy, chemotherapy, or major surgery.
(Dr. R. Chang, Cornell Medical College, New York, NY, USA)
It was found that cancer patients taking reishi extract
showed no significant drop in their peripheral white blood counts
and platelet counts even after three cycles of chemotherapy. Many
patients noticed an increase in appetite. Dr. Shiu concluded that
reishi extract may be a useful adjunctive treatment during chemotherapy.
(Dr. W. Shiu, Dr. T. Leung, and Dr. M. Tao, Department of Clinical
Oncology, The Chinese University of Hong Kong, Hong Kong)
Results suggest that reishi extract can markedly
potentiate immune function via stimulating the production/release
of lymphokines/monokines from T cells and macrophages, and some
of the elevated cytokines are capable of inhibiting tumor cell growth.

"Oral Administration (300mg/kg) of reishi extract
increased the production of IL-2 in mice. Administration of purified
fraction of reishi extract increased the number of peripheral blood
lymphocytes in humans. This effect was thought to be due to stimulation
of T lymphocytes and increased production of IL-2 and IFN-gamma.
(Zhang et al., 1993; Haak-Frendscho et al., 1993)
Ganoderma lucidum has very significant anti-tumor
and anti-cancer effects. High molecular weight polysaccharide compounds
obtained from water extracts markedly inhibited sacroma 180 (SA)
in mice. Injection of the aqueous extract into Lewis lung carcinoma
(LL) bearing mice increased life span up to 195%. This effect was
observed when the ganoderma extract was administered alone or in
conjunction with chemotherapy drugs. The ganoderma extract was non
toxic to cell cultures, and the anti-tumor action was believed to
occur through T-cell activation. (Maruyama et al., 1989; Furusawa
et al., 1992)
With varies clinical and animal research that was
conducted on Ganoderma lucidum, ganoderma lucidum (reishi) concluded
to have these reported actions: anti-tumor activity; induces differentiation;
inhibits histamine release; stimulates immune system in vivo. (Boik,
1996) |
