In ancient Chinese medicine literature, the earliest discussion of ganoderma lucidum is "Shennong Ben Cao Jing", which was published around the first century BC and is the earliest pharmacological work in China. This book contains 365 kinds of medicines, and the drugs contained in the book are divided into the upper, middle and lower three products, the upper drugs are all effective, non-toxic, Ganoderma lucidum resides in the upper products. According to the doctrine of yin and yang and five elements of Chinese medicine, the book divides Lingzhi into five categories, namely, green, dan, yellow, white and black, according to five colors, and also includes purple zhi. The book describes in detail the medicinal properties, odor and main treatment of the six types of Lingzhi. To summarize, Ganoderma lucidum can "replenish the qi of the five organs", "tranquilize the mind", "increase wisdom", and "lighten the body and prolong the life of the immortals by eating for a long time". ". The discussion of Ganoderma lucidum in Shennong's Classic of the Materia Medica has been honored as a classic and cited by successive generations of medical scientists, and has been used to this day.

The 2000 edition of the Chinese People's **** and National Pharmacopoeia contains Lingzhi (Chi Chi, Zi Zhi) substrates as legal Chinese herbs; the Ministry of Health has also previously approved Lingzhi as a new food resource. In this way, Ganoderma lucidum has truly become a medicinal and food Chinese medicine, whether it is used medicinally or as a health food, have obtained the national legal status of medicinal and food. 2000 U.S. publication of the American Herbal Pharmacopoeia and Therapeutic Compendium contains Ganoderma lucidum, the book so far **** contains 10 kinds of Chinese medicine or herbal medicine, Ganoderma lucidum is one of them, see the U.S. pharmaceutical industry on the medicinal value of Ganoderma lucidum is also attached great importance to.

Ganoderma lucidum belongs to the fungi plants, according to its life history, can be divided into three stages, after the maturity of the ganoderma lucidum entity to disseminate spores, after the spores are dispersed all over the world, only 2% to 3% of the spore powder can meet the environment adapted to its growth, and then the formation of the mycelium, and finally become a child entity. Therefore, spore powder, mycelium and fruiting body constitute the three different growth stages of Ganoderma lucidum. Artificially cultivated Ganoderma Lucidum fruiting bodies are grown by inoculating mycelium onto wood or other culture materials, not directly from Ganoderma Lucidum spores. As herbal medicine or health food, all three parts are useful. However, only Ganoderma lucidum (Chi Chi and Zi Chi) fruiting bodies are included in the 2000 edition of the Chinese People's **** and National Pharmacopoeia as legal herbal medicines, while spore powder is not a legal herbal medicine.

Modern pharmaceutical research has proved that Ganoderma lucidum contains many chemical components, among which polysaccharides, triterpenoids, peptides, adenosine, purines and other components are its main active ingredients. It has also been proved that Ganoderma lucidum and its active ingredients have a wide range of pharmacological effects, such as immunomodulation, anti-tumor, anti-radiation and chemotherapeutic agent-induced damage, sedation, cardiotonic and anti-cardiac ischemia, hepatoprotection, hypoglycemia, antioxidant and scavenging of free radicals, as well as anti-aging effects. Clinical studies have proved that Ganoderma preparations can be used to prevent and control chronic bronchitis and asthma, coronary heart disease, dyslipidemia, neurasthenia, insomnia, hepatitis, diabetes and as an adjuvant therapy for tumor radiotherapy.

Based on the pharmacological and clinical research of ganoderma lucidum, our scholars proposed that ganoderma lucidum's function of "supporting the right and fixing the root" is related to its ability to enhance the function of the body's important organs and systems, regulate the body's neurological-endocrine-immune network, and promote the stabilization of the internal environment, i.e., the homeostatic regulation effect. It is related to the homeostatic regulation. "The homeostatic effect is related to the enhancement of the functions of the vital organ systems and the regulation of the neuro-endocrine-immune network of the body, which promotes the stabilization of the internal environment of the body. Research on the chemical composition and pharmacological effects of Ganoderma lucidum has laid a good foundation for the clinical application and product development of Ganoderma lucidum, as well as the quality control of the products.

At present, there are many kinds of Ganoderma lucidum products sold in the domestic market, such as raw herbs, medicinal preparations, and health foods, etc. The efficacy of Ganoderma lucidum is subject to different opinions, and is often exaggerated and untruthful, so the rational application and correct evaluation of Ganoderma lucidum's medicinal value is still a top priority.

In general, Ganoderma lucidum can be used as a therapeutic medicine for some diseases, and for more diseases, it can be used as one of the comprehensive or auxiliary therapeutic drugs. In addition, it can also be used for the health care of sub-healthy people, especially the middle-aged and elderly health care.
