What are the indications of the point located on the ulnar side of the little finger?

The point located on the ulnar side of the little finger corresponds to the Heart channel in Traditional Chinese Medicine (TCM). This specific point is often associated with indications that pertain to emotional and physiological aspects related to the heart and its functions.

The indications of headache, insufficient lactation, and sore throat reflect the interconnectedness of the heart with other systems in the body. Headaches can arise from disturbances in the heart’s qi or blood, and insufficient lactation is often linked to heart yang deficiency or heart blood deficiency, which directly impacts the body's ability to nourish. A sore throat can also be related to heart fire or the influence of emotions, reflecting the connection between the heart and the throat area.

In contrast, the other options include symptoms that are either unrelated to this point’s classical indications or pertain to different channels or organs in TCM. This understanding emphasizes the importance of integrating the location of acupuncture points with their relevant indications for effective practice in TCM.
