Is it effective to use Sanfu patches during the menstrual period?

Generally speaking, whether using cold patch (Sanfu patch) during menstruation is effective depends on the specific circumstances. For some menstrual discomfort caused by cold coagulation and blood stasis, using cold patch during menstruation may have certain effects; however, for other conditions or individuals with special constitutions, the effects may not be obvious or may even cause discomfort. The specific analysis is as follows:

If a woman experiences dysmenorrhea, poor menstrual flow, or dark menstrual blood caused by cold coagulation and blood stasis, applying the warm-natured herbs in the cold patch to specific acupoints may help to warm the meridians, dispel cold, and resolve blood stasis to some extent, thereby helping to relieve menstrual discomfort. In such cases, some effects may be observed.

However, for women experiencing heavy menstrual flow or those with a constitution characterized by blood heat, using cold patch during menstruation may stimulate blood circulation due to the warming effects of the herbs, leading to increased menstrual flow, prolonged menstruation, or even worsening of physical discomfort. In such cases, the treatment may be ineffective or even cause adverse effects.

To better regulate overall health, it is important to stay warm, avoid getting chilled, maintain emotional stability, and avoid excessive fatigue during menstruation. If experiencing menstrual discomfort, appropriate methods of regulation can be selected based on individual conditions, combined with healthy lifestyle habits, to maintain menstrual health.
