1.Treatment of leukopenia.　　2?Treatment of uterine bleeding, including taking birth control pills bleeding, abortion bleeding, on the birth control ring bleeding, uterine fibroid bleeding, postpartum menorrhagia.　　3?Intramuscular injection for the treatment of psoriasis; topical treatment of vitiligo and eczema; intramuscular injection plus topical treatment of pemphigus; internal treatment of vulvar leukoplakia.　　4. Internal and umbilical cord treatment of pediatric enuresis, pediatric diarrhea, salivation.　　The role of psoralen: (a) estrogen-like effect and anti-natriuresis Psoralen can cause changes in the estrous phase of the female mice, so that the uterine weight increased significantly, there is a strong estrogen-like effect.　　Psoralen and isopsoralen have significant anti-sperm implantation effect on mice, female mice intrauterine injection of psoralen and isopsoralen have anti-early pregnancy, the experiment confirms the ancient understanding that psoralen can abort the fetus. The Compendium of Materia Medica listed it as a medicine for aborting fetuses. The Compendium of Materia Medica classifies it as a medicine for aborting fetuses.　　(B) Enhancement of immunity and whitening effect: It has the effect of enhancing the immune function, and can improve the phagocytosis function of mouse peritoneal macrophages. Can promote the growth of granulocyte progenitor cells, and can counteract the injection of cyclophosphamide-induced leukocyte decline, the mechanism may be complementary coumarin excitation of the adrenal cortex and leukocyte elevation.　　(C) has a photosensitizing effect, thus making the skin pigmentation: Tyrosinase is the key enzyme of melanin biosynthesis in the human body. By increasing the activity of tyrosinase in the human body, the complementary lipid promotes the synthesis of melanin and restores the color of the skin at the white spots. To achieve the purpose of the treatment of vitiligo.　　(D) expanding the coronary heart and hemostasis: Psoralen B has a significant role in expanding the coronary arteries, enhance the rat's cardiac contractility, excitation of the frog's heart, against lactic acid-induced heart failure, and has a cardiac effect. Psoralen A also has the effect of coronary expansion.　　Psoralen can make mice shorten the bleeding time and reduce the amount of bleeding.　　Psoralen has a significant inhibitory effect on S180, Ehrlich ascites carcinoma, hepatocellular carcinoma H I 22. Psoralen and 8-methoxypsoralen had significant killing effect on Sl80 ascites-type cells. Psoralenetin and volatile oil both have anticancer effects.
