The most common clinical cause of increased menstrual flow in teenage girls is functional uterine bleeding. As the ovarian function is not yet perfect during puberty, the imbalance of hormone level secretion will lead to the endometrial lining of the uterus not being able to repair as soon as possible, and so there will be a relatively heavy menstrual flow. If you exclude other organic lesions, you can take Tonic Jiale orally, it is recommended to take two tablets twice a day, basically about forty-eight hours after taking Tonic Jiale, the vaginal bleeding will be significantly reduced or disappear. It is also recommended to pay attention to good rest after menstruation, and do not eat cold or drink ice-cold drinks in diet, which will have corresponding effects on menstruation.
