"Scar" refers to the damage caused to the soft tissues of the human skin by physical, biological, chemical, and other factors. This results in severe damage to the soft tissues of the skin that cannot completely self-repair and is replaced by fibrous tissue, leaving behind local symptoms that affect both appearance and function. The presence of "scars" brings enormous physical and mental suffering to patients, especially those left with scars after burns, scalds, or severe trauma.

Addressing scars left by burns and scalds has a long history, dating back thousands of years to the Miao people in the Miao villages. Early on, they discovered methods to treat burns and scalds caused by fire and hot water. Due to the frequent migration of the Miao people in their early history, they often settled in remote and inhospitable mountainous areas and regions plagued by diseases. Engaged primarily in fire cultivation and water farming, they inevitably encountered situations of burns and scalds under these specific conditions. Therefore, almost everyone could recognize and master methods to treat burns and scalds. The formula known today as Miao Medicine for Burns and Scalds was developed and refined over generations of Miao physicians, successfully healing countless patients for centuries.

Burns and scalds refer to injuries caused by direct contact with burning objects, hot liquids, solids, gases, electricity, and other elements that result in scalding or burning of the skin. In some cases, the injury may extend to internal organs due to the direct attack of fire toxins. Common symptoms include redness, swelling, significant oozing, redness and swelling at the site of injury, blistering, and scab formation. In traditional Chinese medicine, scar repair is considered a relatively safe, environmentally friendly, and side-effect-free method of treatment.
