Golden Thread Root (Huang Lian): A Bitter Herb for Damp-Heat, Infections, and Digestive Fire
Introduction
Golden Thread Root, known as Huang Lian (黄连) in Traditional Chinese Medicine (TCM), is a highly bitter and intensely cooling herb used to clear heat, dry dampness, and purge fire toxins. It is a powerful remedy for a wide range of inflammatory conditions, particularly those affecting the gastrointestinal tract, Heart, and Liver. Huang Lian is often used in formulas for infections, diarrhea, ulcers, and mental restlessness.
What Is Golden Thread Root?
Huang Lian is the dried rhizome of Coptis chinensis or related species such as Coptis deltoidea. In TCM, it is classified as bitter and cold, entering the Heart, Liver, Stomach, and Large Intestine meridians. It contains a high concentration of berberine, a compound known for its antibacterial and anti-inflammatory properties. Golden Thread Root is traditionally used to treat damp-heat, high fever, digestive inflammation, and emotional irritability due to Heart fire.
