Women during menstruation can use Angelica sinensis to regulate menstruation and relieve pain. Because Angelica sinensis is good for activating blood stasis, regulating menstruation and relieving pain, moistening and relaxing the bowels, it is a good treatment for women with symptoms such as irregular menstruation, poor menstrual discharge, and stagnant Qi and blood stasis. Because most of the causes of menstrual disorders or low menstrual bleeding in women are due to Qi stagnation and blood stasis, the endometrium does not shed smoothly, and Angelica sinensis has a very good regulating effect on Qi stagnation and blood stasis, so it can be used for menstrual disorders caused by Qi stagnation and blood stasis. However, it should be noted that women with menstrual cramps, excessive bleeding or functional uterine bleeding are not recommended to use Angelica during menstruation as it may aggravate the symptoms of bleeding, so whether Angelica can be used during menstruation should be differentiated according to the symptoms during menstruation.
