Traditional Chinese Uses

Jin Long Dan Cao is the herb of Conyza blinii (Herba Conyzae), a bitter, cold medicinal entering the Lung and Liver channels and classed among Heat-clearing herbs. Its core actions are to clear Heat and resolve Phlegm and to relieve cough and dyspnea, so it is used for Lung-Heat patterns with cough, copious phlegm, and wheezing, and for sore, swollen throat. It also relieves toxicity and promotes urination for damp-heat jaundice.

A further function is to cool the Blood and stop bleeding, applied to nosebleed, coughing or vomiting of blood, bloody stool, and uterine bleeding, as well as mouth ulcers. It is typically decocted (about 6-9 g), while fresh herb may be pounded for topical use on sores or expressed as juice. Use within a formula and under professional guidance.

Botanical Description

Jin Long Dan Cao (金龍膽草) is a Pinyin entry that translates as 'golden gentian herb' or 'golden dragon-gall grass.' While 'Long Dan Cao' alone refers to the well-known TCM herb Gentiana scabra (and related Gentiana species), the addition of the 'Jin' prefix produces a name not standardized in Bensky & Gamble, the Chinese Pharmacopoeia, or other mainstream materia medica. The name may refer regionally to a yellow-flowered Gentiana, to Tripterospermum, or to an unrelated bitter herb used as a folk substitute. Because the identity cannot be established with confidence, no morphological description or slug assignments can be responsibly provided, and substantive fields are left null pending verified identification.
