In addition, the whole grass of the following two plants can also be used as Swertia mussotii medicine:

① Swertia bimaculata

One or two years old herb, height 60 ~ 100 cm. Stem erect, branched. Leaves opposite, elliptic or oblong, apex pointed, base decurrent. Corolla yellowish white, 5-lobed, lobes obovate, with many dark green spots on the upper part, and 2 yellowish green glands on the middle part, round, naked, about 0.1-0.2 cm in diameter.

[collection] harvest in summer and autumn, cut into sections and dry in the shade.

[chemical constituents] it contains about 2-4% of Sophora flavescens, as well as Angelin, yellow gentianin, yellow gentianin glucoside, etc.

Swertia bifasciatus contains isovitexin, isoorientin, 1,3-dihydroxy-4,5-dimethoxyxanthone, 1-O - β - d-glucopyranoside and 3-O - β - d-glucopyranoside of the xanthone, as well as dangyaopicroside and dangyaoside.

[pharmacological action] the bitter glycosides isolated from Chinese angelica are easy to be absorbed on the skin surface. After absorption, they are decomposed to form erythrocentaurin, which can dilate capillaries, activate or promote the enzyme system of skin cells, and improve the biochemical function of skin tissue. Intravenous injection of dangyao solution can increase skin temperature, which is similar to parasympathetic drugs. So we think it can treat alopecia.

In addition, the methanol extract from Japanese herbal medicine can protect the liver damage of mice caused by carbon tetrachloride and promote the redox function of skin. It has radiation like effect.

Bitter, cold.
