Functions: 1 .It enhances people applying oxygen efficiently for their body. A 2-wk ingestion schema of a commercial herbal-based formula is insufficient to elicit positive changes in cycling performance (1, 2). 2 . It protects liver cell and avoids poison chemical damaging. Cordyceps sinensis (Berk.) Sacc (CS) may decrease the damage to hepatocyte by CCl4, and inhibit hepatic fibrogenesis. Six weeks after CCl4 administration, the activity of hepatic insulinase began decreasing. CS could not inhibit the decrease of the activity of hepatic insulinase(3). Cordyceps sinensis could inhibit hepatic fibrogenesis derived from chronic liver injury, retard the development of cirrhosis, and notably ameliorate the liver function. Its possible mechanism involves inhibiting TGFbeta(1) expression, and thereby, down regulating PDGF expression, preventing HSC activation and deposition of procollagen I and III(9). 3 . It delays cell aging and reduces free radical attacking. Aqueous and alcohol extracts of Cordyceps sinensis (Berk) Succ. are used as a traditional medicine in China for the treatment of a wide range of diseases and are reported to have antioxidant and antiapoptotic properties. We therefore examined the ability of aqueous, organic, and alcohol extracts of Cordyceps sinensis to inhibit apoptosis induced either by hydrogen peroxide or Fas-receptor ligation; both stimuli induce apoptosis dependent on reactive oxygen species. Cells pre-incubated with Cordyceps sinensis extracts were equally sensitive to hydrogen peroxide and Fas-mediated apoptosis. Thus, the putative antioxidant and antiapoptotic properties of Cordyceps sinensis are insufficient to rescue cells from apoptosis induced by these stimuli in vitro (5). A polysaccharide isolated from Cordyceps sinensis, a traditional Chinese medicine, protects PC12 cells against hydrogen peroxide-induced injury (7). For medication, the fruiting body (fungus) and the worm (caterpillar) are used together. However, the pharmacological efficiency and the main constituents of the individual parts have not been determined. In the present study the water extracts from the fruiting body and worm of natural Cordyceps were analyzed for their content of nucleosides and polysaccharides; the results showed that the worm had chemical composition similar to the fruiting body. In addition, both the fruiting body and worm of Cordyceps showed similar potency in their anti-oxidation activities in the xanthine oxidase assay, the induction of hemolysis assay and the lipid-peroxidation assay. These results suggest that the function of the worm in Cordyceps is to provide a growth medium for the fruiting body, and that eventually, the worm is totally invaded by C. sinensis mycelia (13). Cordyceps sinensis (Berk.) Sacc. is a time-honored tonic food and herbal medicine in China , where recent research has shown that many of its traditional uses may be viewed from the basis of pharmacological activities. The ongoing exploration of C. sinensis in its wild form and cultured, fermented mycelial products derived from it, are reviewed from English and Chinese literature. Part II concludes the series with a review of C. sinensis in preclinical in vitro and in vivo studies, and open-label and double-blinded clinical trials on the respiratory, renal, hepatic, cardiovascular, immunologic, and nervous systems, and its effects on cancer, glucose metabolism, inflammatory conditions, and toxicological studies. In Part I, which appeared in the Fall 1998 issue of this journal (4(3):289-303), we discussed the effects of C. sinensis on antisenescence, endocrine and sexual functions, atherosclerosis, hyperlipidemia, and free radicals (27). This review presents Cordyceps sinensis (Berk.) Sacc., a fungus highly valued in China as a tonic food and herbal medicine. The extant records show the continued use of C. sinensis is now centuries old. The major chemical, pharmacological, and toxicological studies on C. sinensis and the various derived, cultured, fermented mycelial products currently in use are reviewed from the English and Chinese literature. Preclinical in vitro and in vivo studies and clinical blinded or open-label trials in to date over 2000 patients are reviewed. These studies show the main activities of the fungus in oxygen-free radical scavenging, antisenescence, endocrine, hypolipidemic, antiatherosclerotic, and sexual function-restorative activities. The safety of the fungus, its effects on the nervous system, glucose metabolism, the respiratory, hepatic, cardiovascular, and immune systems, immunologic disease, inflammatory conditions, cancer, and diseases of the kidney will be reviewed in the second part of this article to be published in the winter issue of this journal (28).
4 . It stimulates male mice secreting testosterone. Cordyceps sinensis ( CS ) might contribute to an alternative medicine for the treatment of some reproductive problems caused by insufficient testosterone levels in human males (8). CS stimulated normal mouse Leydig cell steroidogenesis in a dose-dependent relationship. CS at 3 mg/ml significantly stimulated testosterone production (p<0.05). Concerning the temporal relationship, CS at 3 mg/ml stimulated maximal testosterone production between 2 to 3 hr. Interestingly, hCG-stimulated testosterone productions were suppressed by CS in a dose-dependent relationship. CS also reduced dbcAMP-stimulated testosterone productions, which indicated that CS affected signal transduction pathway of steroidogenesis after the formation of cyclic AMP. Moreover, cycloheximide inhibited CS-treated mouse Leydig cell testosterone production, suggesting that new protein synthesis was required for CS-stimulated steroidogenesis (14). Different concentrations of CS and 3 fractions of CS (F1, a water-soluble polysaccharide; F2, a water-soluble protein; and F3, a poorly water-soluble polysaccharide and protein) were added to MA-10 mouse Leydig tumor cells with or without human chorionic gonadotropin (hCG), and the production of steroid and the expression of steroidogenic acute regulatory protein (StAR) were examined. The results showed that CS alone (2-10 mg/mL) stimulated MA-10 cell progesterone production in a dose-dependent relationship. Fractions F1 and F3 (2-10 mg/mL) also had significant (P < .05) stimulatory effects on MA-10 cell steroidogenesis with a dose-dependent relationship. However, fraction F2 did not have an effect on MA-10 cells. CS and F3, but not F1, significantly induced more steroid production in hCG-stimulated MA-10 cells (P < .05). As a temporal relationship, F1 and F3 (2 mg/mL) maximally stimulated progesterone production between 1 and 3 hours after stimulation in MA-10 cells. In addition, CS and F3 significantly enhanced MA-10 cell StAR protein expression, which indicates that CS and F3 may use a cyclic adenosine monophosphate signal transduction pathway to activate MA-10 Leydig cell steroidogenesis in a manner to that of luteinizing hormone (15).

5 .It keeps our body's immune system over-offending to hurt ourselves. H1-A extracted from Cordyceps sinensis suppresses the proliferation of human mesangial cells and promotes apoptosis, probably by inhibiting the tyrosine phosphorylation of Bcl-2 and Bcl-XL. H1-A, a pure compound used in traditional Chinese medicine, is effective in the treatment of autoimmune disorders of MRL lpr/lpr mice. H1-A may be effective in the management of autoimmune disorders, and the modulation of the signal transduction proteins Bcl-2 and Bcl-XL may represent a target for future pharmacologic interventions (10, 29).
6 . It can inhibit tumor growing and improve our immune ability. Water extracts of Cordyceps sinensis (WECS) might be beneficial in the prevention of tumor metastasis as an adjuvant agent in cancer chemotherapy (11). VGH-CS-ME-82, either alone or with IFN-gamma induction, increases the MHC class II antigen expression on hepatoma cell line HA22T/VGH, which will shed light into the present immunotherapy, and make the host immune surveillance more effective against tumor cells with down-regulated MHC class II antigen expression (26). Effects of various fractions of methanol extracts from fruiting bodies of Cordyceps sinensis on the lymphoproliferative response, natural killer (NK) cell activity, and phytohemagglutinin (PHA) stimulated interleukin-2 (IL-2) and tumor necrosis factor-alpha (TNF-alpha) production on human mononuclear cells (HMNC) were studied. Neither CS-36-39 nor CS-48-51 was cytotoxic on HMNC, and that immunosuppressive ingredients are contained in Cordyceps sinensis (30). the therapeutic activity of C. sinensis in Chinese medicine may be related to modulation of TH1 and TH2 cells functions in bronchial airway (17). hat WECS has an anti-metastatic activity that is probably due to components other than cordycepin (23). ccelerated function of Kupffer cells is partially involved in the anti-metastatic action of WECS (22). Inhibition of activated human mesangial cell proliferation by the natural product of Cordyceps sinensis (H1-A): an implication for treatment of IgA mesangial nephropathy (24).

Cordyceps sinensis Cs-Cr is an immunoregulator/biological response modifier of cellular immunity and may be potentially useful in handling immunodeficient or immunosuppressed patients (32). Augmentation of various immune reactivities of tumor-bearing hosts with an extract of Cordyceps sinensis (33). The antitumor effect of water-extract (ECS) prepared from dried Cordyceps sinensis (Berk.) Sacc. (ECS) may be mediated through its immunomodulating action (34). Tumor cell growth inhibitors, other than cordycepin and polysaccharides, are contained in C. sinensis (31). 7 . It can inhibit producing LDL. LDL may play a critical role in mediating mesangial cell hypertrophy or proliferation involved in the development of glomerulosclerosis. Cordyceps sinensis and Cordyceps militaris inhibited, to a certain degree, proliferation of cultured human glomerular mesangial cell induced by LDL (19).
8 . It can reduce risk of hypertension. Cordyceps sinensis (CS)-induced vasorelaxation is mediated by the endothelium possibly by stimulating the release of the nitric oxide and endothelium-derived hyperpolarizing factor. In conclusion, the present study revealed that presence of a constituent in CS which reduces MAP by relaxing the vascular beds directly. However, the effect may be caused by a single active ingredient or by the combined action of many active agents found in the extract (20).
