Absorption mechanism of Laozhangjia black plaster

When treating diseases such as meridians, human meridians and acupoints are generally used as sticking parts. The plaster attached to the body surface stimulates nerve endings, dilates blood vessels through reflection, promotes local blood circulation, improves the nutrition of surrounding tissues, and achieves the functions of detumescence and anti-inflammation. At the same time, drugs penetrate the skin at acupoints and reach subcutaneous tissue, resulting in the relative advantage of local drug concentration, thus playing a strong pharmacological role, and having local effects such as antisepsis, anti-inflammation and pain relief in the treatment of trauma, dermatosis and mucosal lesions. In addition, some irritating drugs can regulate the body function, promote the formation of antibodies and improve human immunity through nerve reflex. At the same time, after the drug penetrates through the skin and mucosa, it enters the systemic circulation through blood vessels or lymphatic vessels, which can produce systemic efficacy and achieve the purpose of treating diseases. Traditional black plaster is prepared by high temperature extraction, and the effective components are seriously damaged. After hundreds of tests, Lao Zhang's plaster finally solved the problem by extracting the effective components that are afraid of high temperature at low temperature and then extracting the effective components that can only be extracted at high temperature at high temperature.
