Our Pain Free Formula is based on Yan Hu Suo Wan, a very effective formula to reduce any kind of pain. Analgesic substances have long been sought after in every medical tradition. The ability to treat pain with non-addicitive substances is essential whenever possible. Acupunture and Chinese herbal medicine have great capacity to do this. According to Chinese medicine, pain results when there is qi and blood stagnation. This means that there is lack of movement and proper circulation. Immediately after and sometimes for years after, the body holds onto a physical injury/trauma. Proper circulation was never restored to the damaged tissue and pain is the result. Resolving qi and blood stagnation may help reduce pain at its source by rejuvinating injured issues and restoring normal circulation.
