Acupuncture to tonify the Lung qi- One of the most powerful points on the Lung channel, lieqi (lung 7), is used to open the lungs and descend the qi to stop coughing. It also clears wind-heat or wind-cold, relieving sore throat, sneezing and sniffling. As part of the Metal Element, lung 7 can help heal deep seated grief or sadness that has gone unexpressed. It is also the "command point" of the head and neck, enhancing circulation to the brain and stimulating memory. This point is often coupled with hegu (large intestine 4) to treat colds, clear the sinuses and strengthens the weiqi or immune system.
