Autoimmune function is extremely complicated. It is not like other functions, about which you would think the stronger, the better. For instance, allergic asthma is caused by excess of some factors in the autoimmune system. It is a sensitive reaction. For a pregnant woman, if some factors in her autoimmune system are hyper, i.e. too active, her body will repel the embryo, and she may fail in her pregnancy. In the perspective of Chinese Medicine, abnormal autoimmune function is the same as an imbalance of Yin and Yang.
Chinese Medicine emphasizes the balance of Yin and Yang and the harmony of the body’s different functions, a concept which is totally alien to Western Medicine.
