Do wormwood patches really work?

The use of mugwort paste will be effective if it meets the cold bleeding and cold pain.
Mugwort is pungent, bitter, warm and slightly toxic, and belongs to the liver, spleen and kidney meridians. It has the efficacy of warming menstruation, stopping bleeding, dispersing cold and relieving pain, and is mainly used for the treatment of all kinds of blood evidence (non-physiological bleeding disorders) and cold pain in the abdomen, cold menstrual disorders, cold uterus, infertility and other conditions.
Mugwort paste also has the efficacy of warming menstruation, stopping bleeding, dispersing cold and relieving pain, and can be applied to acupuncture points on the surface of the body to achieve the effect of treating diseases through stimulation of acupuncture points, but the external application of Mugwort paste is different from the decoction of traditional Chinese medicines, and the medicinal effect it can play is limited.
If patients have epistaxis, metrorrhagia (excessive menstrual flow or dribbling), excessive menstruation and other blood manifestations, or menstrual cold disorders, uterine cold and infertility, it is recommended to go to the hospital in a timely manner, and be treated under the guidance of a professional physician, rather than using medication by oneself to avoid delays in the condition.
