Reishi Info |
| Ganoderma lucidum (hoặc các tên gọi thông thường-Lingzhi, Reishi) là một loại nấm chữa bệnh được đánh giá cao ở Trung Quốc từ trên hai ngàn năm nay do những giá trị y khoa rộng lớn của nó. Từ những thời xa xưa, loại thảo dược quý báu này được dành riêng cho các vị vua, hoàng hậu và các nhà quý tộc. Các đặc tính chữa bệnh của nó được đề cập lần đầu tiên trong cuốn Trung Quốc Thảo Dược Toàn Thư lâu đời nhất dưới nhan đề “Shen Nong Ben Cao Jing” và, đến năm 1578, được Li Shin-chen soạn thành sách tham khảo lớn nhất về thảo dược Trung Quốc dưới nhan đề “Ben Cao Gang Mu”. Với công nghệ khoa học tiến bộ hiện đại và với sự hiểu biết ngày càng gia tăng trong thế giới Tây phương, nhiều công trình nghiên cứu sâu rộng trong các trường đại học nổi tiếng thế giới đã không ngừng chứng minh giá trị dinh dưỡng và sự công hiệu trong việc sử dụng truyền thống thảo dược Ganoderma lucidum.
Trên 40 năm qua, nhiều công trình nghiên cứu về Ganoderma lucidum đã được tiến hành ở Hoa Kỳ, Canada, Nhật Bản, Đài Loan và Trung quốc v.v…. Các chỉ định của Ganoderma lucidum đã được chứng minh là rất có lợi cho những người mong muốn có một chất bổ sung cho chế độ ăn có chất lượng cao để hướng tới một cuộc sống lành mạnh:
Quotations: 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. (Wang SY, Hsu ML, Lee SS, Hong CY, Shiao MS, Dept of Medical Research, Veterans Hospital-Taipei, and National Yang-Ming medical College, Taipei, Taiwan) "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.
