There is usually no saying that women during menstruation should not take Cistanchis. This drug is a yang tonic and can be taken as prescribed by the doctor. Cistanchis belongs to the group of Chinese medicines that warm the kidneys and promote yang (warming and tonifying the yang qi of the kidneys), moistening the intestines and relaxing the bowels. It can be used for treating the symptoms of lumbar and knee pain caused by kidney yang deficiency, lack of semen and blood, impotence in men, infertility in women with uterine cold, clear and long urine, and constipation of dry intestines and bowels. The adverse effects of the drug are not clear, diarrhea, yin deficiency and fire (deficiency of yin and essence in the body, the appearance of hyperactive deficiency fire) is contraindicated. Therefore, there is no saying that women should not take Cistanchis during menstruation, and there is no authoritative clinical information confirming that women should not take Cistanchis during menstruation. It is suggested that patients should take medication under the guidance of Chinese medicine practitioners, and should not take medication blindly, so as not to cause delay in their condition.
