Long Dan Xie Gan Tang

Long Dan Xie Gan Tang from Empirical Health is a classical Chinese herbal formula powder, based on the traditional Long Dan Xie Gan Tang (Gentiana Longdancao Decoction to Drain the Liver), originating from the Qing Dynasty text Yi Fang Ji Jie (Collected Explanations of Medical Formulas, ~1682 AD).

This foundational formula clears excess Liver and Gallbladder fire, drains damp-heat from the lower jiao, and soothes Liver Qi. In modern Western terms, it supports healthy inflammatory balance in the liver and urogenital systems, helps maintain normal bile flow and detoxification processes, promotes comfort during heat-related patterns, and assists with symptom relief in cases of excess heat—making it particularly useful for patterns of Liver fire blazing upward with damp-heat in the lower jiao, such as irritability, short temper, red eyes or bitter taste in the mouth, headache (especially temporal or vertex), rib-side pain or distention, dark or scanty urine, vaginal itching/discharge, genital swelling or pain, difficult/painful urination, ear ringing or sudden deafness (from heat), or insomnia with restlessness, commonly seen in acute conjunctivitis, herpes zoster, urinary tract irritation, prostatitis-like patterns, migraine with anger triggers, or PMS with heat signs in TCM terms.
