Symptoms and TCM Patterns

Huang Lian is widely used to treat a range of conditions, including stomach-damp heat, intestines-damp heat, stomach-heat, severe heat, excess-type conditions, and blood-heat. When assessing a patient's suitability for Huang Lian, TCM practitioners often look for symptoms such as a red tongue and a rapid, full pulse.


While Huang Lian is a powerful herb, it should be used with caution in certain situations. It is contraindicated in cases of cold signs, Yang-deficiency, Yin deficiency, and stomach cold from deficiency. Additionally, it may damage the stomach and spleen if used inappropriately.

Treatment Principles

Huang Lian's versatility is showcased in its wide array of treatment principles. It is used to cool heat, drain stomach fire, drain heart fire, dry dampness, resolve toxicity, clear heat, drain dampness, drain fire, resolve fire toxin, and stop bleeding.

The distribution of its effects across these channels further emphasizes its versatility as a TCM remedy.
