All of the following xi-cleft points treat menstrual disorders EXCEPT?

The xi-cleft points are particular acupuncture points that are often used to address issues related to acute conditions and can be specifically effective in treating menstrual disorders.

PC-4 (Ximen) is primarily associated with issues related to the heart and the pericardium, which can influence emotional well-being and heart-related symptoms, but it does not have a direct association with menstrual disorders. This differentiates it from the other points mentioned.

KI-8 (Jiaoxin) is known for its effects on regulating menstruation and is commonly used for various gynecological concerns. SP-8 (Diji) is recognized for its ability to help with menstrual pain and regulating menstrual flow, making it relevant in treating menstrual disorders. Similarly, KI-5 (Shuiquan) is also directly related to menstrual issues as it helps to regulate the kidney and menstrual cycles.

Thus, while the other options have clear relationships with menstrual health, PC-4's function is more focused on emotional and cardiac issues rather than directly influencing menstrual disorders.
