Can applying Bai Zhi (Angelica dahurica) and yellow wine to the knee treat meniscal effusion?

Generally, the severity of knee conditions is assessed based on symptoms. If discomfort occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under a doctor's guidance. Specific analysis is as follows:

1. Can be treated

Osteoarthritis, trauma, gout, and other conditions may cause cartilage wear, leading to excessive fluid accumulation within the joint capsule of the knee, resulting in meniscal effusion and symptoms such as knee swelling, softness in the joint cavity, and pain. Bai Zhi (Angelica dahurica) is a traditional Chinese herb known for its effects of relieving exterior syndromes, dispelling cold, eliminating wind, alleviating pain, drying dampness, stopping leukorrhea, reducing swelling, and promoting pus discharge. Huangjiu (Chinese rice wine) also has functions of dispelling cold and resolving blood stasis. If symptoms are mild, applying a poultice of Bai Zhi and Huangjiu to the knee joint may help alleviate discomfort caused by knee joint effusion.

2. Cannot be effectively treated

However, if the symptoms of knee joint effusion are severe—such as intense pain, significant knee swelling, leg weakness, and limited mobility—the effectiveness of treating knee effusion with a Bai Zhi and Huangjiu poultice is limited. In such cases, patients should seek medical treatment under professional guidance, including procedures such as joint aspiration, arthroscopic surgery, or synovectomy.

Patients are advised to maintain a positive mindset and follow a healthy diet, consuming more protein-rich foods such as eggs, beef, and shrimp, which can support recovery.
