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.
Acupuncture has been shown to reduce these symptoms of allergies really well, frequently clearing the sinuses within 1 day of a treatment.
Dating back to over 250 BC, the ancient Chinese were exploring Acupuncture, which is a stimulant to the nervous system. They observed how needling affects the local area of needle placement and distal areas from the needle placement, including soft tissues and internal organs. They created maps of influences. When needling certain areas, other certain areas of the body are influenced and certain internal organs are influenced. These ancient maps correlate with modern understanding of neurological anatomy and connective tissue anatomy.
Nothing is supposed to penetrate the skin.
When something does penetrate the skin, the sensory nerves send a message to the brain like an alarm.
The brain responds by directing and coordinating healing activities to the needled area!
