Which acupoint is associated with beriberi symptoms such as toe pain and swelling of the dorsum of the foot?

The acupoint known to be associated with beriberi symptoms, including toe pain and swelling of the dorsum of the foot, is BaFeng. BaFeng is a grouping of eight acupoints located in the area of the foot that correspond to various conditions, particularly those affecting the lower extremities. In the context of beriberi, which is a condition caused by thiamine deficiency, symptoms often manifest in the feet, such as pain and swelling. BaFeng points are specifically utilized to help alleviate these kinds of symptoms, making them particularly relevant in treating the manifestations of beriberi.

In contrast, the other acupoints listed have different primary uses and associations. For example, Ren-12 is more traditionally involved in issues related to the stomach and digestive health, ST-36 primarily focuses on regulating Qi and supporting overall wellness, while BL-40 is associated with lumbar pain and respiratory issues. These points do not specifically target the symptoms associated with beriberi, highlighting why BaFeng is the most appropriate choice for this particular condition.
