Which of the following ear points is effective for treating motion sickness and headaches?

The occiput point is recognized for its effectiveness in treating motion sickness and headaches. In acupuncture and auriculotherapy, the occiput point is associated with various cranial functions and is believed to help alleviate tension and discomfort in the head region. It plays a crucial role in addressing issues that involve balance, which is particularly relevant for motion sickness, as this condition often arises from disturbances in the inner ear and nervous system.

The other points mentioned may serve different functions. For example, Shen men is generally used for its calming effects and to alleviate stress but is not specifically targeted for motion sickness. The eye point typically addresses visual issues and eye strain rather than broader scope problems like headaches or motion sickness. The stomach point may aid in digestive complaints, which can sometimes be associated with nausea due to motion sickness, but it is not directly aimed at addressing these specific issues. Therefore, the occiput is the most appropriate choice for treating both motion sickness and headaches due to its specific indications and relationships in traditional Chinese medicine.
