CHA: (Karen S Vaughan, 8-26-2000): The ganodermas (black G. lucidum, red G. lucidum, G. oregonense, G. tsuga, G. adspersum and G. applanatum) are tonic, immune strengthening, protect against cancer, have anti-tumor properties, calm the spirit, protect and clear heat from the central nervous system, open the heart, lower serum cholesterol and are good for adrenal fatigue and for depression and anxiety. They enter all five zang organs. They have anti-allergic effects, inhibiting histamine production and stabilizing immunoglobulin levels. They lower blood pressure, are antioxidant, antiviral and antibacterial. Combining with astragalus, atractylodes and Ren shen increase phagocytosis, promote immune globulin formation, promote lymphocyte transformation, and induce the generation of interferon. Chinese mountain climbers use Ling zhi to alleviate altitude sickness by oxygenating the blood.
I learned from a Thai doctor with a cancer practice, Santi Rosswong, to make a water decoction of Ganoderma lucidum (Ling zhi) with 10% cordyceps [Dong chong xia cao] for stamina. But since the polysaccharides in ganoderma are quite long, it has been shown to be more effective if the decoction is taken with not less than 500 mg of vitamin C, and 5 mg of folic acid each time. (The vitamin C is based upon Japanese research by Morishige and the folic acid is based upon Santi’s clinical experience.) Take several tablespoons (or more) every three hours. The most important dose is just before retiring, which should be larger. Take the folic acid and vitamin C with each dose.
There are two types of tinctures. One uses a concentrated decoction and adds alcohol to stabilize it. When I make it, I learned from Chris Hobbs to shoot for 25% alcohol to protect the polysaccharides, to ensure that I got between 22% and 28%, the lower number for spoilage and the upper number being a maximum for the polysaccharide protection. This appears to be the best formulation for immune system effects. The other way is to use a high alcohol formation to get the triperetenes, but I understand that this destroys the polysaccharides and differs significantly from the constituents extracted in traditional uses or from powdered extracts. It may have stronger CNS effects however. I know several herbalists who make a high alcohol tincture and add it to the subsequently decocted marc to get the best of both (and they understand that the high alcohol just makes the polysaccharides clump together but does not destroy them). There is not a consensus.
Ling zhi has various steroidal compounds, long chain polysaccharides, bitter triperetenes such as ganodermic acid and some volatile oils. Unlike Echinacea which activates macrophages, ganoderma is not believed to stimulate the immune system directly. It is probably an immune regulator rather than an immune stimulant. Ling zhi mushrooms get to the bone marrow and induce the marrow to put on more nucleated marrow cell mass, according to Jia. The marrow then increases B-cell production, which in turn increases antibodies. The DNA and RNA made in the bone marrow increases production of lymphocytes. This very deep immune nourishing means that it may be appropriate for AIDS patients although the patient should not suffer from undue dampness. For cancer therapy, combined with other fu zheng herbs, Ling zhi can be quite useful, even for patients undergoing chemo and radiation. Hobbs recommends low dose decocted ganoderma with cinnamon bark and orange peel as a tonic drink (for those not suffering from undue dampness) and I find that preparation, with roasted dandelion or chicory, combines well with coffee, helping neutralize coffee’s negative effects.
PLB: Some sources (including Subhuti Dharmananda of ITM) indicate that when ethanol is introduced to a water extract of Ling zhi (at greater than 25% by volume) the polysaccharides are not destroyed, but precipitated. Therefore, in a bottle of Ling zhi extract with over 25% ethanol, the polysaccharides are likely to be stuck to the sides of the bottle or settled at the bottom (or they are still stuck in the manufacturer’s vessels). When attempting to deliberately concentrate the polysaccharides, this is a useful phenomenon. Water extracts may be treated with up to 99% ethanol so polysaccharides – a greyish-white powder – can be claimed. For normal use, hot water extracts are best, and should be preserved with less than 25% ethanol (or as much glycerine as you like).
Weng Weiliang, et al.:
|Effects on central nervous system
|ling zhi preparation could reduce spontaneous activity of mice, strengthen the inhibitory effects of reserpine and chlorpromazine on nerve center, antagonize the excitatory function of benzedrine on nerve center, prolong the pentobarbital sodium induced sleep time, strengthen hypnogenesis effect of pentobarbital sodium at sub-threshold dose, antagonize electrical convulsion. Besides, it also had analgesic effect.
|Effects on respiratory system
|ling zhi had obvious antitussive effect, it could prolong the latent period of cough induced by ammonia stimulation, or decrease the times of cough significantly. chi zhi preparation had spasmolytic effect on smooth muscle contract of isolated trachea induced by histamine, and the effect was directly proportional to the medicine concentration.
|Effects on cardiovascular system
|ling zhi could significantly increase the cardiac contraction, decrease the heart rate in isolated toad heart, increase the contraction force of in situ rabbit heart. chi zhi liquid (3g/kg) could antagonize acute myocardial ischemia caused by hypophysin, significantly lower the high T wave in ECG.
|Hot water extract of ling zhi could lower blood pressure, this effect was the most obvious 3 hours after oral administration. Initial clinic test also proved its blood pressure lowering effect and fat lowering effect. The blood pressure lowering effect of mycelin extracted from the mycelium of ling zhi had the characteristics of taking effect quickly, short action time, and dosage dependence.
|ling zhi could also antagonize blood coagulation, prevent the thrombus formation, inhibit the platelet aggregation, and increase the deformability of aged RBC.
|Effects of improving anoxia tolerance
|chi zhi preparation could increase the anoxia tolerance of normal mice and mice pre-treated isoprenaline under lower pressure and normal pressure circumstance. Dried powder of fermented ling zhi could also increase the anoxia tolerance ability of mice, particularly the ability of cardiac muscle, and lower the oxygen consumption whole animal, improve the cardiac metabolism of anoxic animals.
|Effects of lowering blood sugar
|Ethanol extract of chi zhi had no influence over the increase of insulin secretion 10 minutes after oral administration of glucose, but had inhibitory effect on the continuous decrease of plasma insulin 30 minutes after the administration. It could also inhibit the increase of blood sugar induced by injection of adrenalin or oral administration of glucose. Polysaccharides of ganoderans A, B, C and heteroglycan isolated from ling zhi were injected intraperitoneally to mice at the dosage of 100mg/kg, the results showed that it could blood sugar.
|Effects of protecting liver and detoxification
|The increase of serum GPT and accumulation of liver triglyceride in mice induced by CCl4 injection could be obviously improved by oral administration of ethanol and ether extract of fruit body onload=”highlight();” of zi zhi and chi zhi. Besides, the extract could also relieve fatty liver caused by ethionine, promote the liver regeneration and strengthen the detoxifying function.
|Immune hepatic injury was markedly induced by BCG or BCG plus inflammatory cytokines in BALB/c mice in vivo and in vitro. Under BCG-stimulated condition, augment of the liver weight and increase of the serum/supernatant ALT level were observed, as well as granuloma forming and inflammatory cells soakage were observed by microscopic analysis within liver tissues. Moreover, NO production was also increased by BCG or/and CM stimuli in the culture supernatant, and a lot of iNOS positive staining was observed in BCG-prestimulated hepatic sections. Application of Ganoderma lucidum polysaccharide (GLP)significantly mitigated hepatic tumefaction, decreased ALT enzyme release and NO production in serum/supernatant, improved the pathological changes of chronic and acute inflammation induced by BCG-stimuli in mice. Moreover, the immunohistochemical result showed that GLP inhibited iNOS protein expression in BCG-immune hepatic damage model. The study indicates that NO participates in immune liver injury induced by Mycobacterium bovis BCG infection. The mechanisms of protective roles by GLP for BCG-induced immune liver injury may be due to influence NO production in mice.
|Effects on smooth muscle
|chi zhi preparation could inhibit the smooth muscle activity of isolated rabbit intestines and isolated ileum of Guinea pig, and the effect increased with the increase of medicine concentration. Concentrated solution of fermented chi zhi could also obviously inhibit the contraction of isolated rat uterine.
|Effects of immune regulation
|Extract of mycelium of bo gai ling zhi could significantly promote the phagocytosis rate of celiac macrophages and activity of lysosome in mice, obviously inhibit DNA synthesis in lymphocytes and T and B lymphocyte transformation induced by ConA and bacillus coli endotoxin. ling zhi polysaccharide had certain immunoenhancing effect.
|The polysaccharide component with a branched (1–>3)-beta-D-glucan moiety from G. lucidum (PS-G) has shown evidence of enhancement of immune responses and of eliciting anti-tumor effects. Annexin V staining and MTT assays reveal that PS-G is able to inhibit spontaneous and Fas-induced neutrophil apoptosis, and this effect of PS-G is enhanced by the presence of zVAD (a caspase inhibitor) and GM-CSF. The antiapoptotic effect of PS-G is diminished by the presence of wortmannin and LY294002 (two PI-3K inhibitors), but is not altered by PD98059 (a MEK inhibitor). Western blotting indicates the stimulating effect of PS-G on Akt phosphorylation and its inhibition of procaspase 3 degradation, which occurs in neutrophils undergoing spontaneous apoptosis or triggered death by Fas. Taken together, PS-G elicitation of antiapoptotic effects on neutrophils primarily relies on activation of Akt-regulated signaling pathways.
|A fucose-containing glycoprotein fraction which stimulates spleen cell proliferation and cytokine expression has been identified from the water-soluble extract of Ganoderma lucidum. Proteomic analysis of mouse spleen cells treated with this glycoprotein fraction showed approximately 50% change of the proteome. Further studies on the activities of this glycoprotein fraction through selective proteolysis and glycosidic cleavage indicate that a fucose containing polysaccharide fraction is responsible for stimulating the expression of cytokines, especially IL-1, IL-2 and INF-gamma.
|ling zhi could obviously inhibit the allergic reaction of Guinea pig passively sensitized by egg albumen antiserum, tetanus toxoid antiserum on antigen attack, it could also significantly inhibit the release of allergic mediators such as histamine and SRS-A by lung tissue of Guinea pig actively sensitized by egg albumen antiserum or tetanaus toxoid antiserum on antigen attack. This effect would strengthen with the increase the dosage of ling zhi.
|Water decoction of ling zhi could inhibit the growth of tumor. Hot water extract of mycelia of artificially cultured chi zhi had inhibitory effect on the growth of fibrosarcoma and metastasized focus of lung. Ganodenic acid, a kind of triterpene isolated from chi zhi, had cell toxicant on cultured liver carcoma in vitro.
|The triterpene-enriched fraction, WEES-G6, was prepared from mycelia of G. lucidum by sequential hot water extraction, removal of ethanol-insoluble polysaccharides and then gel-filtration chromatography. It’s found that WEES-G6 inhibited growth of human hepatoma Huh-7 cells, but not Chang liver cells, a normal human liver cell line. Treatment with WEES-G6 caused a rapid decrease in the activity of cell growth regulative protein, PKC, and the activation of JNK and p38 MAP kinases. The changes in these molecules resulted in a prolonged G2 cell cycle phase and strong growth inhibition. None of these effects were seen in the normal liver cells. This findings suggest that the triterpenes contained in G. lucidum are potential anticancer agents.
|A study was designed to investigate the protective effect of a dietary water-soluble extract from cultured medium of Ganoderma lucidum (Rei-shi or Mannentake) mycelia (designated as MAK) on the induction and development of azoxymethane (AOM)-induced colon tumors in male F344/Du Crj rats. A total of 80 animals were divided into five groups at six weeks of age, groups 2, 3 and 4 being given weekly subcutaneous injections of AOM (15 mg/kg body onload=”highlight();” weight) for the initial 3 weeks to induce colon tumors. Rats in group 1 and 5 were injected with the vehicle, 0.9% (w/v) saline, following the same schedule. Rats in groups 1, 2, 3, 4 and 5 were fed MF, MF, 1.25% MAK, 2.5% MAK and 2.5% MAK diets, respectively, starting 1 week before AOM treatment and throughout the six-month experimental period. There were no significant differences in number of ACF, total AC and AC per site among groups 2 to 4, but the tumor incidence was significantly lower, and tumor size was smaller in group 4 (AOM + 2.5% MAK) than in group 2 (AOM + MF). Additionally, beta-catenin positive tumor cell nuclei were significantly decreased in the MAK-fed rats (groups 3 and 4), which also demonstrated lowering of the PCNA labeling index and a shortened germinal region in the colon. The present results thus indicate that dietary MAK could act as a potent chemopreventive agent for colon carcinogenesis.
|Spores or dried fruiting body onload=”highlight();” of G. lucidum inhibit constitutively active transcription factors AP-1 and NF-kappaB in breast MDA-MB-231 and prostate PC-3 cancer cells. Furthermore, Ganoderma inhibition of expression of uPA and uPA receptor (uPAR), as well secretion of uPA, resulted in the suppression of the migration of MDA-MB-231 and PC-3 cells. The data suggest that spores and unpurified fruiting body onload=”highlight();” of G. lucidum inhibit invasion of breast and prostate cancer cells by a common mechanism and could have potential therapeutic use for cancer treatment.
|Different concentrations of Ganoderma lucidum(Leyss ex Fr) Karst Compound(GLC) (from 4 mg/ml to 12 mg/ml) could promote human bone marrow granulocyte-macrophage colony forming unit (CFU-GM) proliferation, but suppressed the growth of K562 leukemic cell colonies, and IC50 was 9.2 mg/.ml. The data from liquid culture demonstrated that GLC could suppress K562 cells proliferation in a dose-dependent(from 4 mg.ml-1 to 20 mg.ml-1) and time-dependent(from 1-5 days) manner. K562 cells could be induced to differentiate into more mature erythrocytic cells by 4 mg/.ml and 8 mg/ml GLC. It is concluded that GLC may be a good medicine for leukemia therapy.
|Water extract of chi zhi could prolong the average life span of drosophilas, but it could neither lengthen the maximum life time, nor inhibit the brain MAO-B activity in mice.
|To investigate antiherpetic substances from Ganoderma lucidum, various protein bound polysaccharides, GLhw, GLhw-01, GLhw-02, GLhw-03, were isolated by activity-guided isolation from water soluble substances of the carpophores. These substances were examined for their antiviral activities against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) by plaque reduction assay in vitro. Among them, the acidic protein bound polysaccharide, GLhw-02 of a brownish substance, exhibited the most potent antiherpetic activity with 50% effective concentrations (EC50) of 300 approximately 520 microg/ml in Vero and HEp-2 cells, and its selectivity indices (SI) were more than 20. GLhw-02 was identified to consist mainly of polysaccharide (approximately 40.6%) and protein (approximately 7.80%) by anthrone test and Lowry-Folin test, and showed the usual molar ratio (C:H:O = 1:2:1) of carbohydrates by elemental analysis. These results suggest that GLhw-02 possesses the possibility of being developed from a new antiherpetic agent.
|A new highly oxygenated triterpene named ganoderic acid alpha has been isolated from a methanol extract of the fruiting bodies of Ganoderma lucidum together with twelve known compounds. The structures of the isolated compounds were determined by spectroscopic means including 2D-NMR. Ganoderiol F and ganodermanontriol were found to be active as anti-HIV-1 agents with an inhibitory concentration of 7.8 micrograms ml-1 for both, and ganoderic acid B, ganoderiol B, ganoderic acid C1, 3 beta-5 alpha-dihydroxy-6 beta-methoxyergosta-7,22-diene, ganoderic acid alpha, ganoderic acid H and ganoderiol A were moderately active inhibitors against HIV-1 PR with a 50% inhibitory concentration of 0.17-0.23 mM.
|Mucosal healing effect
|Fruiting bodies of Ganoderma lucidum (GLPS) at 250 and 500 mg/kg by intragastric input caused ulcer-healing effect in the rat; this was accompanied with a significant suppression of tumor necrosis factor (TNF)-alpha gene expression, but with an increased ornithine decarboxylase (ODC) activity. In RGM-1 cells, GLPS at 0.05, 0.25 and 1.0 mg/ml significantly enhanced [3H]thymidine incorporation and ODC activity in a concentration-dependent manner. However, these effects were abrogated by the addition of the ODC inhibitor, DL-alpha-difluoromethyl-ornithine (DFMO). GLPS at 0.25-1.0 mg/ml also increased mucus synthesis, as indicated by the increased D-[6-3H]glucosamine incorporation in RGM-1 cells. Furthermore, GLPS at 0.05-1.0 mg/ml increased the c-Myc protein expression. These findings indicated that GLPS produced a mucosal healing effect in the rat model, perhaps due partly to the suppression of TNF-alpha and induction of c-myc and ODC gene.
|Antiperoxidative, antiinflammatory, and antimutagenic effects
|The ethanol extract of the mycelium of Ganoderma lucidum occurring in south India showed significant inhibition of Fe2+-induced peroxidation of lipid in rat liver (IC(50) 510 +/- 22 micro g/ml) and 37% inhibition of croton oil-induced peroxidation on the mouse skin at 20 mg/0.1 ml/skin. Carrageenan-induced acute and formalin-induced chronic inflammatory edema were inhibited by 56 and 60%, respectively, by the extract at 1,000 mg/kg body onload=”highlight();” wt (i.p). The extract at a concentration of 5 mg/plate showed inhibition of mutagenicity elicited by direct acting mutagens, NaN(3) (55.5 and 75.7%) and MNNG (50.0 and 57.5%) for S. typhymurium strains TA100 and TA102, respectively. The extract at the same concentration also inhibited mutagenicity elicited by NPD (52.4 and 64.2%) and B[a]P (60.7 and 59.6%) for TA98 and TA100 strains, respectively. The B[a]P was activated in the presence of rat liver microsomal (S9) fraction. The results revealed that ethanol extract of Ganoderma lucidum mycelium possessed significant antiperoxidative, antiinflammatory, and antimutagenic activities. The findings suggest a medicinal use for the ethanol extract of the mycelium of G. lucidum occurring in South India.
|Mice peritoneal macrophages were injured by reactive oxygen species (ROS), derived from tert-butylhydroperoxide (tBOOH). The survival rate of macrophages was measured by MTT assay, and the morphological changes of macrophages were observed under light and electron microscopes. It was found Ganoderma lucidum polysaccharides peptide (GLPP) (50, 100, 200 mg/kg, ip for 5 d) could inhibit the foam cell formation and necrosis of macrophages. The survival rate of macrophages was increased. GLPP (3.125, 12.5, 50, 200 mg/L) given to the cultured macrophages brought the same protective effects. Under the electron microscope it was found that GLPP (100 mg/kg, ip, for 5 d) could protect the organelle such as mitochondria against injury by tBOOH. The results indicated that GLPP had significant scavenging ROS and antioxidant effects.
|Hot water extract of Ganoderma lucidum dose-dependently exhibited antioxidative effect on mouse liver and kidney lipid peroxidation; this indicated that hepatic and renal homogenates have a higher malonic dialdehyde level in an ethanol administered group than in the Ganoderma lucidum treated group. It was concluded that the hepatic and renal protective mechanism of Ganoderma lucidum, might be due at least in part to its prominent superoxide scavenging effect. Ganoderma extract could protect the liver and kidney from superoxide induced hepatic and renal damages.
|The amino-polysaccharide fraction (designated as ‘G009’) from Ganoderma lucidum was tested for the ability to protect against oxidative damage induced by reactive oxygen species (ROS). G009 significantly inhibited iron-induced lipid peroxidation in rat brain homogenates and showed a dose-dependent inactivation of hydroxyl radicals and superoxide anions. It also reduced strand breakage in phiX174 supercoiled DNA caused by UV-induced photolysis of hydrogen peroxide and attenuated phorbol ester-induced generation of superoxide anions in differentiated human promyelocytic leukaemia (HL-60) cells. These findings suggest that G009 from Ganoderma lucidum possesses chemopreventive potential.
|Hot-water extract of Ganoderma lucidum had good radioprotective ability, as well as protection against DNA damage induced by metal-catalyzed Fenton reactions and UV irradiation. Water-soluble polysaccharide isolated from the fruit body onload=”highlight();” of Ganoderma lucidum was as effective as the hot-water extract in protecting against hydroxyl radical-induced DNA strand breaks, indicating that the polysaccharide compound is associated with the protective properties.
