Are Sanfu Patches really effective?

Applying Sanfu patches can be effective, but they are not suitable for everyone. For individuals with yin deficiency and damp-heat, Sanfu patches may help dispel coldness in the body, but they should only be applied at正规 hospitals and under a doctor's guidance.

Are Sanfu Patches Really Effective?

For asthma or rhinitis patients with poor physical resistance, applying Sanfu patches during the hottest days of summer (Sanfu period) can enhance bodily resistance, eliminate internal coldness, and improve symptoms of physical weakness.

Keep the patch dry—avoid direct exposure to air conditioning and refrain from bathing immediately after application to prevent skin irritation or ulceration. Sanfu patches are effective. Rooted in traditional Chinese medicine's concept of harmony between humans and nature, Sanfu patches are used during the hottest days of summer to treat diseases that tend to flare up or worsen in winter.

The body’s yang energy is strongest in summer, so treating cold-related chronic conditions during this time can yield twice the result with half the effort. Conditions such as chronic bronchitis, bronchial asthma, and allergic rhinitis often worsen in winter, significantly affecting health and quality of life. Applying these patches in summer helps regulate body constitution, strengthen the body, especially in those who are frail, and preserve yang energy.

Common Sanfu patches typically contain herbal ingredients such as cinnamon bark (Rougui), astragalus root (Huangqi), agarwood (Chenxiang), and ginger (Shengjiang). Applied to specific acupoints, they stimulate the skin and help regulate the body's internal environment. They may also serve as adjunctive therapy for rheumatoid arthritis, dysmenorrhea, uterine coldness, hypertension, and coronary heart disease.

There are certain risks associated with using Sanfu patches; therefore, their use is recommended only under medical supervision.
