From the perspective of Chinese medicine, the body’s constitution is too weak and leads to recurrent fires. The most common factor is that the body is susceptible to infections, and the foci of infection in the body are not completely and thoroughly cleared, so there will be recurrent infections and prolonged situations, such as respiratory, digestive, pelvic, urinary and skin infections. 2, non-infectious diseases can also lead to recurrent fires when the immune system is low. The body can be infected with rheumatism, tuberculosis, immune tissue disease, and connective tissue disease. 3, recurrent fire is also related to the body’s very low immunity, such as the body is infected with severe anemia, tuberculosis, tumor disease or infected with serious AIDS, etc., will occur recurrent fire.
