The aqueous solution of total alkaloids, glycosides, flavonoids and phenolic compounds of Cyperus seu also has the effect of strengthening heart and slowing heart rate, and has obvious antihypertensive effect.

2. Estrogen-like effect: The ovariectomized rats showed that the volatile oil of Cyperus seu had mild estrogen-like activity. The volatile oil was injected subcutaneously twice at an interval of 6 hours, and the vaginal epithelium was completely keratinized 48 hours later. 0.3 After 3 ml administration, many white blood cells appeared in the large number of keratinocytes. The appearance of white blood cells may be caused by the stimulation of volatile oil.
