Who are the suitable candidates for Sanfu Patch (Three伏 Patches)?

Sanfu Patch is suitable for various populations, primarily due to its effects of warming the body, dispelling cold, promoting blood circulation, and unblocking meridians. It is appropriate for individuals with excessive dampness or poor immunity to help eliminate internal dampness and enhance resistance; for those suffering from respiratory conditions such as chronic bronchitis and asthma to alleviate symptoms; and for people with chronic osteoarthritis to relieve joint pain. However, it is essential to consult a doctor before use and determine suitability based on individual constitution and medical condition.
