6 pharmacological effects
Alcohol inhaler 0.5% can inhibit the movement of Paramecium. The oestrogen contained in the female uterus of the developing female rats was excited first, that is, after 1-2 weeks of application, the weight of the uterus increased, the myometrium of the uterus increased and the hyperplasia and hypertrophy of the endometrium, and the length of the epithelial cell layer of the uterus increased. After continuous application for 3-4 weeks, it showed an inhibitory effect. The sub-division was degraded and the epithelial cell layer was flattened; however, there was also no estrogen-like substance in it. The saponins contained therein can increase the tension of isolated rabbit intestine and accelerate the exercise. Its leaves can make the animal (rats, guinea pigs, and sheep) goiter. [Toxic] It can cause photoallergenic dermatitis.
