What does the AnMian point target specifically?

The AnMian point is primarily associated with the treatment of insomnia and other sleep-related issues. Its location directly influences the calming of the mind and the regulation of the body's stress response, making it particularly beneficial for individuals who struggle with sleep disturbances. The stimulation of this point encourages relaxation and can help alleviate anxiety, creating a more conducive environment for natural sleep patterns to arise.

The other options, while they address various health concerns, do not directly relate to the AnMian point. For instance, lumbar pain and dysmenorrhea are typically addressed through points that correspond to the lower back and reproductive organs, respectively. Tongue swelling and aphasia relate to different issues that are specifically linked to speech and systemic health, whereas vomiting and cough involve points that target the digestive system and respiratory functions. Therefore, AnMian's specific targeting of insomnia and related sleep issues makes it a unique and critical point in acupuncture practice.
