Drinking dandelion usually does not affect the delay of menstruation. Dandelion is a herbal medicine that can play a role in reducing heat and diuresis, as well as improving the state of the organism. Drinking dandelion can generally play a role in regulating the endocrine function. In clinical practice, if a patient has eczema or measles, drinking dandelion can relieve the symptoms. Dandelion cannot affect endocrine disorders or reduce the function of the ovaries, so drinking dandelion alone will not affect the menstrual cycle. If menstruation is clinically delayed, it may be delayed due to pregnancy, or it may be delayed due to ovarian dysfunction, mental stress, or exertion.
