Can I use the Sanfu Patch during my menstrual period?

Whether one can use the Sanfu贴 (Sanfu patch) during menstruation depends on individual constitution and menstrual flow. If menstrual flow is light and symptoms such as cold uterus are present, applying the Sanfu patch may help warm the body, dispel cold, promote blood circulation, and resolve blood stasis, thereby alleviating symptoms. However, if menstrual flow is already heavy, using the Sanfu patch might increase bleeding and lead to menstrual irregularities. Therefore, the decision to use the Sanfu patch during menstruation should be made under the guidance of a physician, with careful consideration of individual circumstances.
