Chitin is widely distributed in nature, such as shells of aquatic crustaceans such as shrimps and crabs, exoskeletons of mollusks and many fungi. In traditional Chinese medicine, tortoise shell and sole cartilage have been used as medicine for a long time. According to statistics, crabs, insects, mollusks and fungi produce up to 1000 billion tons of chitin every year, which is the second richest wild resource after plant cellulose.
There are a considerable number of chitin production enterprises in China, which are rich in resources. Most of them are taken from shrimp shells and crab shells, with a large output. Chitin also exists in the bones of jellyfish, mushrooms, earthworms and cuttlefish, but it is generally not used for mass production.
The most direct cause of human illness is the decline of immunity. Chitin enters the human body, through activating cells, enhances the body's own immune ability and resists various diseases. When human blood and body fluids are maintained at normal pH (PH=7.4), the immune function is good. If you deviate from this value, it will lead to a decline in immunity. Chitin can adjust the PH value of human body to make it normal or slightly alkaline, thus improving human immunity.
At the "Seminar on Development and Application of Crustacean Resources Research Association of China" held in 1997, experts such as Ma Xiaotong from Hebei Health and Epidemic Prevention Station introduced the experimental research of chitin. The results show that chitin can enhance cellular immunity, humoral immunity and phagocytosis of mononuclear macrophages. Yang and other experts of Chinese Academy of Traditional Chinese Medicine conducted a comprehensive and systematic study on the application of tortoise plastron, which proved that it can reduce plasma viscosity and improve pain value, indicating that tortoise plastron has the function of removing blood stasis and relieving pain. The harmony between man and nature is the highest state of health preservation, and it is also the crystallization of thousands of years of medical experience of traditional Chinese medicine. With the upsurge of "returning to nature and advocating green", the concept of "whole nature" in TCM health care shows great vitality, which provides a profound theoretical basis for health care in line with the 24 solar terms.
