Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine compositions, and more specifically, to a topical plaster for external injuries and its preparation method. Background Technology

[0002] External injuries, a common type of injury in daily life, encompass a wide range of conditions from minor abrasions to serious traumas, such as falls, sprains, fractures, and dislocations. In Traditional Chinese Medicine (TCM) theory, the treatment of external injuries emphasizes both internal and external therapies. Through the combined use of Chinese herbal medicines, the aim is to promote blood circulation, remove blood stasis, reduce swelling and pain, accelerate wound healing, prevent infection, and speed up the recovery process.

[0003] External plasters are a common type of traditional Chinese medicine composition used to treat external injuries. External injury plasters typically consist of a base, medicinal ingredients, and excipients. The base serves as the carrier of the plaster and commonly includes water-soluble and oil-soluble bases. The medicinal ingredients vary depending on the therapeutic purpose, such as those promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, and antibacterial and anti-inflammatory drugs. Excipients are used to adjust the viscosity and stability of the plaster. Based on the different medicinal ingredients, external injury plasters can be divided into several types, such as those promoting blood circulation and removing blood stasis, those reducing swelling and relieving pain, and those with antibacterial and anti-inflammatory properties. These plasters each have their own focus in treating external injuries, while also possessing a certain comprehensive therapeutic effect.

[0004] However, the existing topical ointments for external injuries are not yet effective enough in promoting blood circulation, removing blood stasis, reducing swelling and relieving pain, and need to be improved. Summary of the Invention
