Toxicological effects, residue levels and risks of endocrine disrupting chemicals in Chinese medicine: A review

Abstract

Abstract Endocrine disrupting chemicals (EDCs), which exist in all aspects of our lives, may interfere with the synthesis, action and metabolism of human sex steroid hormones, resulting in development and fertility problems as well as obesity and the disturbance of energy homeostasis. Traditional Chinese medicine (TCM) that used worldwide possess the satisfactory function of disease prevention, treatment and health care, and this natural medicine seems to be favored due to its low side effects. From planting to processing, TCM may be polluted by various EDCs. Many studies pay attention to this problem, but there are still few reviews on the residues and toxicity risks of EDCs in TCM. In this paper, researches related to EDCs in TCM were screened. The possible contamination sources of TCM from planting to processing and its toxic effects were introduced. Moreover, the residues of metals, pesticides and other EDCs in TCM as well as the health risks of human exposure to EDCs through ingestion of TCM materials were reviewed.
