Acupuncture is a complementary medical practice that entails stimulating certain points on the body, most often with a needle penetrating the skin, to alleviate pain or to help treat various health conditions. current research shows that acupuncture probably excites the biochemical responses in the human body via the nerves. Acupuncture itself doesn’t directly release feel-good chemicals that can aid in inflammation, stress, and so forth, according to Study, but it works higher up the chain such as affecting the pituitary gland to produce the extra hormones. Another hypothesis is that acupuncture works by reducing pro-inflammatory markers, or proteins, in the body. Yet another hypothesis applies specifically to how acupuncture can be used to treat nerve damage, such as chemo-induced peripheral neuropathy, a condition that often causes numbness or weakness in the feet and hands.
