My acupuncturist first used this on me, with massage.....and sold me my first jars. Later, I began buying it through this site. Strong stuff, but very effective. I use it on my hip and leg. Almost immediately the pain/ache is relieved. Sent a sample jar to my 92-yr old aunt who, for the first time, was not able to walk after a long winter of sitting. Her reaction was amazement. The pain was relieved and she began her active life again. Sent some to my cousin who has knee and foot problems. She just told me how she could feel the balm working as she retired for the night.....and then woke up with literally no pain in her knees. My 94-yr old mother has shoulder tissue damage that flared up so badly a couple of months ago that the slightest pressure on her shoulder caused her to cry out in pain. I gently applied balm and took her to the ER. The doctor asked what this product is, and then told me to keep applying it to her shoulder as she recovered.....with the help of an anti-inflammatory drug she had prescribed. My acupuncturist claimed that this product is better than Tiger Balm. I'm sold on it.
