Modern medical research shows that Cordyceps has the ability to engulf tumor cells four times more than selenium. Specifically, cordycepin contained in Cordyceps can significantly enhance the ability of red blood cells to adhere to tumor cells and inhibit tumor growth and metastasis; it can significantly enhance the number of white blood cells and platelets, and rapidly improve the symptoms of vomiting and nausea, poor appetite, hair loss and insomnia after radiotherapy. In the United States, Cordyceps has been classified as a new anti-tumor drug and entered clinical phase III. In fact, Cordyceps is a combination of insect and fungus. The insect is the larva of Cordyceps batrachis moth, and the fungus is Cordyceps fungus. Whenever the snow and snow melts in the snowy mountain meadows above 3800 meters above sea level in high summer, the batrachis moth with small body and flower body will leave thousands of eggs on the flower leaves. The eggs turn into tiny worms and burrow into the moist and loose soil, absorbing nutrients from the roots and stems of plants, gradually making their bodies fat and white. At this point, the spherical ascospores encounter the Cordyceps batrachianus moth larvae and burrow inside the body, absorbing nutrients and sprouting mycelium. When the larvae of Cordyceps batrachians eat leaves with Cordyceps fungus they also become Cordyceps. The larvae infected by the fungus gradually move to a place 2 to 3 cm from the surface, and die by the end of the head, which is called “winter worm”. Although the larvae die, the fungus in the body grows day by day until it fills the whole body. In the late spring and early summer of the following year, a small purple-red grass grows from the head of the worm, about 2 to 5 cm high, with a pineapple-shaped capsule at the top, and this is the “summer grass”. This is a good season to collect wormwood because it is the most developed and has the highest nutrient content. From the perspective of regulating cellular immune function, Cordyceps or Cordyceps sinensis can suppress cellular immune function. Some scholars have done experimental research on Cordyceps anti-corneal transplant rejection, and the results suggest that Cordyceps can play the role of immunosuppressant after corneal transplantation, and has the effect of strengthening hormone. It exerts cellular immunomodulatory effects by selectively acting on T-suppressor cells in the T-lymphocyte subpopulation. The aqueous extracts of Cordyceps and Cordyceps militaris showed significant protective effects in mice with hypofunctioning T cells in the thymus and spleen, and increased peripheral leukocytes in normal mice. In terms of regulating humoral immunity, the oral administration of Cordyceps preparations to mice, Cordyceps can increase the level of serum hemolysin, and in vitro experiments can directly stimulate the proliferation of thymus cells in mice, and the stimulating effect is dose-related. Experiments have proved that Cordyceps has multifaceted immune effects, either enhancing or inhibiting the function of different lymphocyte subpopulations, or showing bidirectional regulation, without affecting the function of the body’s hematopoietic system and without lymphocyte toxicity. In clinical practice, it can treat both immunocompromised diseases and immune diseases. 2.Anti-cancer effect Natural Cordyceps and artificial Cordyceps mycelium aqueous extract have significant inhibitory effect on the growth of primary foci and spontaneous lung metastasis of subcutaneous transplanted Lewis lung cancer in mice by intraperitoneal injection. In vitro experiments, Cordyceps directly inhibited laryngeal cell growth and colony formation. The results showed that Cordyceps aqueous extract significantly enhanced the ability of natural killer cells to kill tumors in patients with active leukemia, but had an inhibitory effect on LAK cell activity. This shows that the enhancement of natural killer cell activity by Cordyceps aqueous extract has an extremely important role in its anti-tumor immunity, and it has a significant enhancement of natural killer cell activity in normal subjects and leukemia patients. In addition, the alcoholic extract of Cordyceps sinensis reduced the incidence of carcinogenesis in mice. It has enhanced effect on the activity of natural killer cells in mice and humans in vivo and in vitro, protects immunity and inhibits the formation of tumor clones in mice. 3. Effects on cardiovascular system Anti-myocardial ischemia and arrhythmias: Cordyceps aqueous infusion has inhibitory effects on isolated frog heart, in vivo frog heart and rabbit isolated heart, slowing down the heart rate, but significantly increasing cardiac output. In anesthetized dogs, sedative infusion (1:1) of 0.5-1 ml/kg lowered blood pressure significantly and respiratory reflex excitation. However, intraperitoneal or intramuscular injections had no effect on blood pressure. It is tentatively suggested that the hypotension induced by sedative injection may be the result of a non-specific response due to the crude preparation. The alcoholic extract of Cordyceps sinensis significantly counteracted the arrhythmias induced by aconitine and barium chloride in rats and also counteracted the arrhythmias induced by toxic trichothecene G in guinea pigs. Subcutaneous injection of Cordyceps militaris alcoholic extract significantly prolonged the survival time of hypoxic mice and increased the nutritive blood flow in mice, heart and brain tissues M-0 Both Cordyceps militaris and Cordyceps militaris aqueous infusion could significantly prolong the survival time of mice under normoxic conditions. The alcoholic extract and fermentation solution of Cordyceps can counteract myocardial ischemia induced by posterior pituitary hormone in rabbits by intravenous injection; intraperitoneal injection can significantly reduce the increase in oxygen consumption induced by isoprenaline in mice. Hypotensive and vasodilatory effects: Protein extract of Cordyceps sinensis, administered intravenously to mice, significantly inhibited aortic pressure. 32 mg/kg concentration of protein extract resulted in a decrease in aortic pressure by 58 earth 4 mm Hg (from 107-4-6 to 49 —-/-3 mm Hg) and the duration of action was more than 45 min. The action of epinephrine pretreated aortic rings with protein extracts at a concentration of 150 µg/ml induced a high degree of vasodilation of 68.9?.3%. It was shown that the protein extract-induced vasodilation was indirectly caused by nitrogenous compounds released from the endothelial cell layer and endothelial cell layer-derived superfusion factors, which contain components that relax the vessel wall to reduce aortic pressure present. 4, the effect on renal function Cordyceps decoction infusion can reduce the acute kidney injury caused by gentamicin, delay the appearance of proteinuria in rats, slow down the rise of blood urea nitrogen, urinary lysozyme and N-acetyl a l3 amino glucosaminidase are lower than the control group. 5.Antibacterial effect In vitro test proved that: Cordyceps acid has inhibitory effect on Staphylococcus, Streptococcus, Bacillus nasalis, Bacillus anthracis, Bacillus hemorrhagic septicemia of pigs and fungi such as Stachybotrys, Stachybotrys gypsum and Stachybotrys woolly. The effect on Mycobacterium tuberculosis has been reported differently, but most of them believe that Cordyceps sinensis alcoholic infusion has inhibitory effect, and the inhibitory concentration is between 1:4,000 and 1:100,000. In general, the main effects of Cordyceps on tumors are to enhance immunity and to kill and inhibit cancer cells. Reduce the side effects of chemotherapy and radiotherapy. Under normal circumstances, although every human body contains oncogenes, they are in a quiescent or low expression state, which is not only harmless to the cells but also plays an important role in maintaining normal cell function and does not cause cancer in people. If external factors, such as environmental factors (dietary and nutritional factors, chemical carcinogens), certain viruses, radiation and other carcinogenic factors invade the body, they will activate the oncogenes in the cells and cause normal cells to deteriorate into cancer cells. Generally, after cancer cells deteriorate, cancer patients are thin, and even after resection surgery, cancer cells will still fission, which is fatal. What’s more, if two patients with cancer cells deteriorate at the same time and treated under the same conditions, one may die and one may survive. Cancer cells proliferate indefinitely and endlessly, so that the nutrients in the patient’s body are greatly consumed, and protein anabolism and catabolism are both enhanced, but anabolism exceeds catabolism and can even take away the protein breakdown products from normal tissues, resulting in a cachectic state of severe depletion of the body. As a result, the body can be in a state of severe depletion and cachexia. Thus, the body becomes thin day by day. Cancer cells vary in size and shape, usually larger than their source cells, with different nuclear morphology, and may appear as meganuclei, binuclei or multinuclei. The chromosomes in the nucleus are aneuploid, with some chromosomes missing and others increasing in number. Abnormal changes in chromosomes in normal cells initiate the apoptotic process, but in cancer cells, apoptosis-related signaling pathways are impaired, which means that cancer cells are immortal. Cordyceps has a significant positive effect in inhibiting the deterioration of cancer cells: Direct effect: The antitumor active components of Cordyceps directly inhibit the growth of tumor cells by inhibiting nucleic acid and protein synthesis or glucose transport across membranes Indirect effect: The immune response of the body is an important factor affecting the occurrence and development of tumors. The anti-tumor effect is mediated by the host. Cordyceps has the effect of “moistening the lung, strengthening the kidney, benefiting the essence and blood, and tonicizing both yin and yang”, which can regulate the immunity of the human body and strengthen the resistance of the human body, and only when the immunity of the human body is improved can the “cell mutiny” be effectively avoided. Only when the immunity of human body is improved can we effectively avoid “cell mutiny”.
