Also known as Ling You or Japanese gentian, Gentiana scabra grows in mountainous valleys. With a pronounced bitter taste and cold nature, it enters the liver, gallbladder, and stomach meridians. Although its bitterness is notable, its straight upward growth signifies its ability to promote the ascent of Qi. Regarded as a superior herb in the Shennong Ben Cao Jing, Gentiana scabra is credited with treating conditions such as alternating chills and fever, convulsions, and disruptions in Qi flow, as well as for stabilizing internal organs and detoxifying the body. Despite its cold and bitter properties, its Qi-uplifting and heat-clearing benefits can be highly effective when combined appropriately with other ingredients.
