Acupuncture treatment of lung heat has the advantages of no side effects and quick results. The specific method is a combination of local treatment and overall regulation. Local treatment involves acupuncture to remove the secretions from the roots of acne, while overall regulation is achieved by using plum blossom acupuncture or pricking the blood for the bladder meridian to clear the lung fire. The patient has had acne on her face and back for 2 years.
