Any substance used to treat diseases, like a copper plate, has two sides, one is beneficial and the other is harmful. Only when it is used correctly can it exert its medicinal effect. If it is the result of drug abuse, it will produce toxicity. Believe it or not, drinking clean drinking water can make a completely healthy person, in some cases, fatal. Therefore, any conscientious doctor can't just consider its helpful side and ignore its harmful side when using drugs. Now, let's take a look at what ancient Chinese medicine said about the toxicity of Ganoderma lucidum. According to the record of Shennong Herbal Classic, the earliest Chinese herbal medicine book in China about 2000 years ago, Chinese herbal medicines can be divided into three types according to their medicinal properties: shangyao, traditional Chinese medicine and remedy. 1, classified as a class of drugs, all have a common feature, that is, curing diseases and preserving health without disease. They have no toxic side effects and can be used for a long time without time limit. 2, the classification of medium drugs is to be used for the treatment of a certain disease, they may have some side effects, and they should be stopped immediately after the disease is cured. 3, the classification of inferior drugs is toxic, can only be used in absolutely necessary exercise, and it is a specific time point, such as chemotherapy drugs can be classified into this category. Shennong's Classic of Materia Medica lists Ganoderma lucidum as a disease-free medicine, and holds that Ganoderma lucidum has the functions of benefiting heart qi, calming the heart and calming the nerves, nourishing liver qi and strengthening bones and muscles. Ganoderma lucidum Cao Xian has inherited the experience and wisdom of 3000 generations, and with more than 50 years of contemporary scientific research, the position of Ganoderma lucidum in tradition, biochemistry, medicine and academia has been very clear. Research results are often published in various academic journals and papers published by universities, medical institutions and research institutions, such as picture books, science and medicine. Ganoderma lucidum has also been included in the American Herbal Pharmacopoeia and Treatment Outline. Ganoderma lucidum (Ganoderma lucidum and Ganoderma lucidum fruiting body) is also officially listed as a legal Chinese herbal medicine in People's Republic of China (PRC) Pharmacopoeia. Ganoderma lucidum and its products have three characteristics: first, they are non-toxic and have no side effects; Second, it does not target an organ; Third, it can promote the normalization of all organ functions. These three characteristics determine its important position in disease prevention and treatment.
