Local nerves within ill tissues gather information about the chemistry and activities of ill tissue, then sends that information to the brain. The brain then finds the healing solution, sends nerve impulses that direct and coordinate chemistry and activity to return the ill tissue to a healthy balance. An object penetrating through the skin into the body, is seen as a crisis by the body. By needling the ill tissues, this stimulates the local nerves to increase information about the ill tissue to the brain, and increases the brains healing responses sent back to the tissue.
