Which symptoms might SiShenCong help alleviate?

SiShenCong, also known as the Four Spirit Points, is a group of acupuncture points located on the scalp. These points are particularly effective in addressing neurological and psychological conditions. The symptoms associated with headaches, vertigo, and insomnia can often be linked to disruptions in the body's energy and blood circulation, particularly in the head and brain area.

Stimulation of SiShenCong is believed to enhance mental clarity, improve sleep quality, and alleviate headaches. In acupuncture practice, these points are often utilized for conditions that involve the neurological system, where both physical tension (like tension headaches and migraines) and psychological aspects (such as stress and anxiety leading to insomnia) can be addressed. Therefore, it is fitting that SiShenCong can effectively help alleviate these specific symptoms, making it the correct answer.

The other options would involve different techniques or points that are more suited to their specific conditions, such as back pain and muscle spasms, gastrointestinal discomfort, or respiratory problems, which require a different approach in acupuncture treatment.
