Disease description:

I previously heard that the "Sanfu Patch" must be applied when entering the first "Fu" period. May I ask, does the Sanfu Patch have to be applied exactly on the first day of the first "Fu" period?

Generally speaking, Sanfu贴 (Sanfu Tuo) does not have to be applied on the first day of the beginning of the "Sanfu" period; it is sufficient to apply it at any time during the Sanfu days. Sanfu Tuo is one of the characteristic therapies in traditional Chinese medicine that combines acupuncture, meridians, and herbal medicine. It involves applying medicinal herbs directly onto specific acupoints, where the herbs create a thermal stimulation effect to achieve therapeutic and preventive health benefits. Sanfu Tuo is specifically used during the Sanfu period based on the TCM principle of treating winter diseases in summer.
