Abstract
Description
Technical Field
[0001] This invention relates to the field of traditional Chinese medicine preparations, and more specifically, to a traditional Chinese medicine preparation for treating skin burns. Background Technology
[0002] Burns are a common traumatic injury in clinical practice. They can be caused by a variety of factors, including high temperature, open flame, boiling water, and steam. After a burn, the skin barrier is damaged, making the wound prone to redness, swelling, exudation, and pain. It is also highly susceptible to bacterial infection. If not treated promptly or properly, it can lead to delayed wound healing, scar hyperplasia, and in severe cases, even systemic infection, tissue necrosis, and other complications, causing irreversible damage to the patient's skin appearance and physiological function. There is an urgent clinical need for safe, effective burn treatment agents with excellent wound repair effects.
[0003] Currently, clinically used preparations for treating skin burns are mainly divided into chemically synthesized and traditional Chinese medicine preparations. Although chemically synthesized preparations can have antibacterial and pain-relieving effects to a certain extent, they have problems such as strong wound irritation, easy development of drug resistance, and only single symptomatic treatment without addressing wound repair. Furthermore, long-term use may cause secondary damage to the skin. Traditional Chinese medicine burn preparations have become a research hotspot in burn treatment due to their natural ingredients, low toxicity and side effects, and the synergistic effect of multiple components in antibacterial, anti-inflammatory, and tissue-regenerating and wound-healing effects. However, they still have many technical shortcomings.
[0004] Existing traditional Chinese medicine (TCM) burn preparations are mostly in the form of ointments and powders, which suffer from problems such as difficulty in controlling the release rate of active ingredients and low bioavailability. Furthermore, some preparations use only a single extraction process for the raw materials, resulting in insufficient extraction of active ingredients and limited efficacy. Simultaneously, most TCM burn preparations lack optimized dosage form design, leading to poor wound adhesion, easy detachment, and an inability to continuously provide an effective environment for wound healing. This can also further increase the risk of wound infection due to external contamination. In addition, some TCM burn preparations lack scientific formulation, simply mixing herbs without classifying and extracting them according to their properties, failing to achieve comprehensive therapeutic effects such as anti-inflammatory, antibacterial, and tissue-regenerating wound healing, and thus failing to meet clinical needs for rapid wound healing and reduced scar formation.
[0005] Based on this, developing a traditional Chinese medicine burn preparation with scientific compatibility of Chinese herbs, sufficient extraction of effective components, and reasonable dosage form design, which can achieve synergistic effects of anti-inflammatory, antibacterial, and tissue regeneration and wound healing, as well as good wound adhesion, controllable release of effective components, and high bioavailability, has become a technical problem that urgently needs to be solved by those skilled in the art.
