Is the Sanfu贴 applied to the Zusanli points on both legs?

　　Zusanli (ST36) is an important acupoint in traditional Chinese medicine, located on the lower leg and belonging to the Stomach Meridian. Generally, Sanfu patches can be applied to the Zusanli points on both legs or on just one leg, depending on individual circumstances. It is recommended to use Sanfu patches as directed by a healthcare provider. If any discomfort occurs, medical attention should be sought immediately. The detailed analysis is as follows:

　　1. Both legs

　　According to traditional Chinese medicine theory, stimulating the Zusanli point can regulate organ function, improve gastrointestinal issues, relieve abdominal discomfort, and enhance immune function. Applying Sanfu patches to both legs is suitable for individuals seeking comprehensive body regulation and overall immune enhancement. Stimulating the Zusanli points on both legs simultaneously helps promote smooth flow of qi and blood throughout the body, regulate organ functions, and achieve systemic coordination and balance.

　　2. One leg

　　On the other hand, applying patches to only one leg is typically appropriate when dealing with specific or localized symptoms. If a health issue or symptom primarily affects one leg, the Sanfu patch may be applied solely to the affected leg's Zusanli point. This allows for more targeted stimulation of the specific area, potentially providing better relief for localized symptoms. For example, focusing on the side where leg pain or other local discomfort occurs may be more effective.

　　During application, attention should be paid to the duration; leaving the patch on for too long may cause skin allergies or other adverse reactions.
