Progress in research on applying Sijunzi Decoction in treating digestive malignant tumor.

Patients with digestive malignant tumor always have their immune function, especially the cellular immunity, suppressed to a certain extent. Traditional Chinese medicine (TCM) holds that Pi-Wei is the essence of postnatal life, and the genesis and development of digestive tumor are chiefly due to the insufficiency of vital-qi, which makes the body open to the invasion of evil pathogens. Starting from regulating the immune function of organisms, researchers recently obtained some therapeutic effects by applying the Chinese recipe, Sijunzi Decoction, in the treatment of digestive malignant tumors. In this paper, the related studies on the concerned basic theory and clinical application were reviewed.
