Are Sanfu patches helpful for individuals with a cold body constitution?
Generally speaking, Sanfu patches (three伏贴) are beneficial for individuals with a cold constitution. The detailed analysis is as follows:
Individuals with a cold constitution often exhibit symptoms such as cold intolerance, cold hands and feet, cold abdominal pain, diarrhea, or joint pain that worsens in cold conditions. Sanfu patches can help improve this kind of constitution. These patches typically contain warming herbs such as ginger, mugwort leaves, and cinnamon bark. Applied on specific acupoints during the hottest days of summer (Sanfu days), they utilize the strong yang energy of nature along with the warming properties of the herbs to synergistically enhance the body's yang energy and expel cold pathogens. The warm herbs penetrate through the skin, helping to unblock the meridians, harmonize qi and blood, strengthen the functions of internal organs, improve overall blood circulation, and reduce discomfort caused by cold stagnation. Long-term, regular application may gradually improve the imbalances associated with a cold constitution.
Prior to application, a qualified physician should determine the constitution type to confirm it is indeed a cold constitution. The duration of each application should be carefully controlled, with the initial session being relatively short to assess skin tolerance. If significant itching or redness occurs at the application site, the patch should be promptly removed to avoid scratching and potential infection. Cold foods should be avoided during the application period, and keeping warm to prevent catching a chill is important.
