Final answer:
The point mentioned, found on the radial side of the index finger near the nail, doesn't have a clear indication from the provided excerpts but is typically used in Chinese medicine for local hand issues or as determined by meridian theories.
Step-by-step explanation:
The point located on the radial side of the index finger and at 0.1 cun from the nail corner is used in Chinese medicine, often related to acupuncture. It specifically doesn't match any presented indications such as pain of the eye, nasal obstruction, or sore throat. In traditional practices, points in this region could be associated with issues of the hand or local areas according to meridian theories, but without exact traditional context or agreed upon indication in practice, it's not possible to provide a detailed indication for the point from the provided excerpts. However, general practice involves using nearby points for issues like hand pain or carpal tunnel syndrome, where the median nerve is compromised, leading to symptoms in the thumb and first two fingers.
