Generally Dendrobium has no effect on menstruation. For menstrual diseases such as low menstrual flow and late menstruation caused by yin deficiency, Dendrobium may have some improving effect. Dendrobium is a common Chinese medicine with sweet flavor and slightly cold nature. It belongs to the stomach and kidney meridians. It has the effect of benefiting the stomach and generating fluid, nourishing Yin and clearing heat. It is used in the treatment of heat illness and injury to fluid, dry mouth and thirst, deficiency of stomach yin, little food and dry vomiting, deficiency of deficiency heat after illness, deficiency of kidney yin, darkness of the eyes and unclear vision, weakness of sinews and bones, and deficiency of yin and fire. The adverse reactions of Dendrobium are not clear. Dendrobium does not have the effect of activating or stopping bleeding, and its nature is not too cold, so it is not a drug that women should use with caution or prohibited during menstruation. If used regularly under the guidance of a professional doctor, it will not cause any effect on women’s menstruation. If the menstrual disease is identified as Yin deficiency, taking Dendrobium may have some therapeutic effect. However, the effect of single dendrobium is limited, and should be treated under the guidance of a professional physician. Chinese medicine should be used under the guidance of a professional Chinese medicine practitioner, and should not be used blindly on its own, so as not to aggravate the condition.
