Can I take Da Huang Zhe Chong Wan during my menstrual period?

It can be taken in moderation if there is no significant excessive bleeding or physical weakness during menstruation, and if recommended by a physician. However, it should not be used if there is heavy menstrual bleeding, a cold and weak constitution, or a tendency to bleed easily. If in doubt, it is advisable to consult a doctor in advance. Detailed explanations are as follows:

Dahuang Zhechong Wan (Rheum and Insect Pills) has the functions of promoting blood circulation to remove blood stasis and relieving pain by unblocking the meridians. It is commonly used to treat diseases such as angina pectoris due to blood stasis blocking the meridians and stroke with hemiplegia. If a female experiences significant symptoms of blood stasis during menstruation, such as poor menstrual blood flow, dark color, or blood clots, and a physician determines that treatment to promote blood circulation and resolve blood stasis is required, the medication may be taken in moderation under medical supervision. At this time, the medicine can help improve blood circulation and relieve related symptoms.

Some women may experience deficiency of qi and blood or have a cold constitution during menstruation, or may have underlying bleeding disorders. The blood-activating ingredients in Dahuang Zhechong Wan may exacerbate menstrual bleeding, leading to increased blood loss or prolonged menstruation. Additionally, individuals with a cold constitution may experience adverse reactions such as worsened abdominal pain and darker menstrual blood after taking the medication. Therefore, this group of people should avoid using this medication during menstruation.

While taking the medication, attention should be paid to monitoring bodily reactions. If any abnormalities occur, such as significantly increased bleeding, dizziness, or fatigue, the medication should be discontinued immediately and medical attention should be sought promptly.
