Chuan Lian Zi, also known as Toosendan Fructus or Sichuan Chinaberry Fruit, is a bitter, slightly cold, and slightly toxic herb used in Traditional Chinese Medicine (TCM) to regulate Liver Qi, relieve pain, clear heat, and kill parasites. It is most valued for treating pain and discomfort related to Liver Qi stagnation, especially in the chest, flanks, abdomen, or genitals. Its cooling and dispersing nature also makes it useful for heat-related conditions with dampness and parasites in the digestive system.
