Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine external preparations, specifically to a type of external application of traditional Chinese medicine powder for relieving cavitary effusion and its preparation method. Background Technology

[0002] Joint effusion is a common clinical condition, often caused by factors such as trauma, inflammation, and degeneration. It leads to fluid accumulation in the joint cavity, pleural cavity, and abdominal cavity, causing symptoms such as pain, swelling, and limited mobility, significantly impacting the patient's quality of life. Currently, there are various treatment methods for joint effusion, including oral medications, aspiration, and surgery. However, these methods have certain limitations. Oral medications often need to be absorbed through the gastrointestinal tract, which may irritate the digestive system, and some drugs reach low concentrations at the lesion site, resulting in limited therapeutic effects. Aspiration is an invasive procedure that may cause complications such as infection and bleeding, and the effusion is prone to recurrence. Surgical treatment is more invasive, requires a longer recovery time, and is more expensive.

[0003] Traditional Chinese medicine (TCM) topical preparations have unique advantages in treating articular effusion. They act directly on the affected area, have a rapid onset of action, and avoid the gastrointestinal reactions associated with oral medications, resulting in higher safety. However, existing TCM topical preparations suffer from problems such as unreasonable formulations, complex preparation processes, unsatisfactory therapeutic effects, and long improvement cycles for effusion. Some preparations also contain added chemical components, which may cause adverse reactions such as allergies. Therefore, developing a scientifically formulated, simple-to-prepare, safe, and effective topical TCM powder that can rapidly improve the symptoms of articular effusion has significant clinical importance and market value.
