Sarapin is a natural medicine that is used for chronic pain relief. Sarapin is a biological medicine – which means it is derived from a naturally occurring organism (the Pitcher plant). It works by stopping pain signals in the nerves of the spine where they exit the spinal column. It does not affect any other nerve functions or motor functions and is not affected by heat or cold. This natural substance is commonly used to treat myofascial pain syndrome, sciatic pain and intercostal neuralgia.
