So, how to know the hyped Chinese medicine from the perspective of Chinese medicine? In order to listen, we invited Professor Weng, the founder of the Department of Health and Rehabilitation of Beijing University of Chinese Medicine, to write an article. Expert: Weng Weijian, founder, professor and doctoral supervisor of health rehabilitation major of Beijing University of Chinese Medicine, and vice president of Health Care Society of China Traditional Chinese Medicine Society. About 40 years ago, Cordyceps sinensis was just an ordinary Chinese herbal medicine. The price is not expensive, and it has never surpassed ginseng and velvet antler. Now it is worth more than gold! Why is this happening? Cordyceps sinensis can "strengthen yang and tonify kidney" and improve sexual function, which is simply a wonderful "myth"! Before the Qing Dynasty, it did not include Cordyceps sinensis. This product is a complex of Cordyceps sinensis and its host insect, Batmoth larva. More than 2000 years ago, in the eyes of ordinary people, it was just a bug that died in winter and a strange thing that sprouted on its head in spring. I don't think it is useful or valuable. Even the Compendium of Materia Medica written by Li Shizhen, a great doctor in the Ming Dynasty, did not include this kind of bug. It was not until the Qing Dynasty that a medical book named Materia Medica from the Heart listed Cordyceps sinensis as a medicinal material for the first time. In the eyes of Chinese medicine, Cordyceps sinensis is just an ordinary Chinese medicine. After nearly a hundred years of clinical practice, Chinese medicine believes that it is sweet and flat. Enter the lung and kidney meridians. It has the functions of tonifying lung, consolidating exterior, tonifying kidney and replenishing essence. It is suitable for cough and asthma due to lung deficiency, hemoptysis due to lung strain, spontaneous sweating and night sweats. In recent decades, Chinese medicine has also achieved good results in the treatment of chronic bronchitis, tuberculosis, weakness after senile diseases, tepid limbs, fear of cold, and easy to catch a cold. So at that time, Cordyceps sinensis was just a common Chinese medicine for treating lung and kidney diseases blindly. Although animal experiments in recent years show that Cordyceps sinensis has certain effects of enhancing immunity, delaying aging, resisting oxidation, resisting hypoxia, resisting fatigue and improving the reproductive rate of mice, clinical experiments show that Cordyceps sinensis has no effects of "strengthening the body and strengthening the yang and tonifying the kidney" to improve sexual function for normal people, and it has certain toxic and side effects after long-term administration. Therefore, normal people, especially patients with low fever, night sweats, flushed face, dry mouth, dizziness, numbness of limbs, itchy skin, body trembling and constipation caused by hyperactivity of liver yang, are not suitable. In recent years, it is not uncommon for some elderly people to take Cordyceps every day to "strengthen yang and tonify kidney" in order to make old trees sprout, dead trees meet spring and restore youthful vitality. I once met a middle-aged male patient who was doing jewelry business in Yunnan. He said that there were some sexual dysfunction before, and the problem was not serious, but now it is not working at all. I asked him why, but he was embarrassed to say that he chewed 10 more Cordyceps sinensis every day and drank yellow wine to help him. I felt his pulse 90 times per minute and saw his tongue coating, which was light and clean, without coating, purple and dark as pig liver. I thought to myself, the only androgen in this man's body is going to burn out! According to the introduction of Chinese medicine and Chinese medicine dealers, there are not a few patients who treat fatigue, cough and asthma, hemoptysis and other diseases caused by deficiency of lung and kidney with Cordyceps sinensis. It is mostly used for people who have economic conditions and want to use Cordyceps to tonify kidney, strengthen yang or prolong life. According to drug dealers, Cordyceps sinensis has been industrialized and commercialized in recent years. It has become a high-grade gift, a collectible and a valuable commodity with constant appreciation. Where there is demand, there is supply. If the supply is insufficient, dig three feet to find it. If you can't find it, look for fake and shoddy products. At present, the common cottage versions of Cordyceps sinensis are: Cordyceps yaxiang, Cordyceps Liangshan, Cordyceps militaris, Cordyceps Sinkiang, Cordyceps Cladosporium and Bombyx Batryticatus. Artificial Cordyceps is made of flour or gypsum. , processed into the shape of Cordyceps with a mold, and then colored with advertising color. There is also a kind of weight-increasing Cordyceps sinensis, which is to add a wire to the real Cordyceps sinensis to increase the weight. It seems that if you want to buy Cordyceps, you must go to a regular pharmacy to avoid being fooled.
