Prof. Zhang Zhili has practised traditional medicine for more than 40 years, hence an accumulation of rich clinical experience. As we have been fortunately guided by him in medical practice we would like to share with readers his experience in treatment of eczema as follows:rnrnAnalyses of PathogenesisrnProf. Zhang holds that eczema is often caused by both endogenic and exogenic pathogens conflicting in skin and muscles: endogenic factors refer to improper diet or over-intake of irritative foods which may hurt the spleen and stomach, resulting in dysfunction of the spleen in transport and, as a result, leading to the accumulation of dampness-heat in the body; and exogenic factors refer to the invasion of exogenic pathogenic wind, dampness and heat. Moreover, a prolonged course of the illness may exhaust yin and blood and, consequently, t pathogenic dryness factor into wind-evil. In the case of children, it is mostly caused by pathogenic heat stagnating in the gastrointestinal region due to weak congenital resistance and improper diet.
