Accupressure - An ancient system of medicine from China.
What is accupressure?

According to the Chinese philosophy two forces govern the body: the active Yang and the passive Yin. Disease occurs due to imbalance of these forces. 

How does it work ?

Accupresure aims to correct this imbalance by applying pressure to specific points on the body. This redirects the flow of life-force or Chi through special nerve-like channels known as meridians. Stimulation of accupressure points releases endorphins in specific parts of the brain contributing to relief from unpleasant symptoms.

Accupressure is commonly resorted to by masseurs to relax the body. Acupuncture is an advanced use of the same theory where instead of digital pressure, the meridians are stimulated by inserting needles.
