An acupressure wristband that is claimed to relieve the symptoms of motion sickness and other forms of nausea is available.
The first formally recognized mention of qi is in the Chinese writings of the Shang dynasty oracle bones which were produced between the 16th to 11th century B.C.
Possibly the earliest evidence of use of the meridian system for health purposes has been found in Europe. Ötzi the Iceman, a 5,000 year old mummy found preserved in an Alpine glacier, seems to have tattoos, some of which correspond to points that a modern acupuncturist or tui na specialist would use to treat symptoms of diseases that Ötzi seems to have suffered from, including digestive parasites and degenerative bone disease. However, it is difficult to speculate on the meaning of the tattoos as to whether they served a decorative, religious, or a medical function.
Many East Asian martial arts also make extensive study and use of acupressure for self-defense and health purposes (chin na). The points or combinations of points are said to be used to manipulate or incapacitate an opponent. Also, martial artists regularly massage their own acupressure points in routines to remove blockages from their own meridians, claiming to thereby enhance their circulation and flexibility and keeping the points "soft," or less vulnerable to an attack. Attacking the acupressure points is one theme in the wuxia genre of movies and novels.
