Background technique

"Lingshu Nine Needles and Twelve Origins" said: "I have sons and thousands of people, support the people, and collect their rent and tax. I mourn that they don't pay, but I have a disease. I want not to be poisoned, useless stone needles, and I want to use microneedles to treat Its meridians regulate its blood and qi, and manage its ingress and egress meeting." Poison is a drug that is harmful to the human body ("Shuowen Jiezi": "poison, the grass that harms people"). It is used to treat sores and sores. To attack it with poison", Bianstone is used to cut carbuncle and drain pus. Both sores and carbuncles with pus are in the late stage of the disease and are more serious. Therefore, the ancients hoped to use microneedles to dredge the meridians, regulate qi and blood, and treat the disease at the beginning of the disease, so as to prevent the disease from developing, so that it can avoid the pain of poison and meteorites.

The skin is mainly composed of three layers, mainly divided into epidermis, stratum corneum and dermis. Among them, the stratum corneum is a dead tissue without blood vessels and nerves. The thickness of the stratum corneum is about 10-20um, which mainly has a barrier effect on the absorption of drugs. The epidermis is located at a distance of about 50um to 100um under the epidermis. The epidermis contains a small amount of living cells and nerves, but does not contain blood vessels. The dermis is the deepest part of the three skin layers, and it contains a large number of living cells, blood vessels and nerves.

Traditional acupuncture and moxibustion generally use individual acupuncture needles to pierce the required acupuncture points of the human body.
