The dried root of Gentiana macrophylla, G. straminea, G. crassicaulis, or G. dahurica (Gentianaceae). Enters the Stomach, Liver, and Gallbladder channels. Bitter, pungent, and neutral, it is the mildest and most balanced of the wind-dampness-dispelling herbs, called the 'moistening agent among wind medicinals.' It treats both heat and cold impediment patterns while also withdrawing vacuity heat and clearing damp-heat, making it especially suitable for chronic impediment with yin vacuity and heat.

秦艽含龙胆生物碱及苦苷，现代研究显示其具抗炎、镇痛、解热及升血糖（动物实验）作用，与传统祛风湿、清虚热之功相符。
Gentiana macrophylla contains iridoid alkaloids (gentianine) and gentiopicroside, with anti-inflammatory, analgesic, antipyretic, and (in animal studies) glucose-elevating effects that parallel its traditional wind-damp dispelling and vacuity-heat clearing use.
《中药学》（Bensky）指出秦艽为风药中之润剂，可用于热痹。
Bensky describes Qin Jiao as a moistening wind-medicine suitable even for hot bi (joint) patterns.
