Zhao's health tennis elbow patch can be directly attached to the painful part, which can dispel cold and relieve pain, relax tendons and promote blood circulation, improve tissue metabolism and nutrition, and has the functions of relieving pain, reducing swelling and promoting tissue recovery. Generally speaking, a patch can last for two to three days, and 30 to 40 days is a course of treatment. Changing one patch at a time can make the skin rest and the effect is better! I used to treat tennis elbow with Zhao's healthy tennis elbow patch, and I felt that one patch was better than the other. It's a good medicine of Chinese medicine!
