The genus Gentiana (English name: gentian) includes the alpine species G. makinoi Kusn., G. triflora Pall.var. japonica (Kusn.) Hara, the pale yellow-flowered Japanese gentian G. algida Pall. (illustration), the small alpine species G. nipponica Maxim., as well as the annual or biennial grassland species G. zollingeri Fawc. (illustration), G. squarrosa Ledeb. and the wetland species G. thunbergii (G.Don) Griseb. (illustration). The rhizomes and roots of Gentiando contain bitter substances such as the bitter glycoside gentiopicrine and gentianine, and in traditional Chinese medicine it is called gentian gall bladder and is used as a bitter stomachic, and is also used in combination with other herbal medicines to reduce fever, hepatitis, sore throat, otitis media, high blood pressure, and urethritis.
