The Death Touch refers to any martial arts technique that can kill using seemingly less than lethal force targeted at specific areas of the body. The concept known as Dim Mak (simplified Chinese: 点脉; traditional Chinese: 點脈; pinyin: diǎnmài; literally "press artery"; Jyutping: dim2 mak6), alternatively diǎnxuè (simplified Chinese: 点穴; traditional Chinese: 點穴) traces its history to Traditional Chinese Medicine Acupuncture. Tales of its use are often found in the Wuxia genre of Chinese martial arts fiction. Dim mak is depicted as a secret body of knowledge with techniques that attack pressure points and meridians, said to incapacitate or sometimes cause immediate or even delayed death to an opponent. There is no scientific or historical evidence for the existence of a touch of death.
The concept known as Vibrating Palm originates with the Chinese martial arts Nei Jing ("internal") energy techniques that deal with the Qi energy and the type of force (jin) used. It is depicted as "a technique that is part psychic and part vibratory, this energy is then focused into a wave". According to a United States National Institutes of Health consensus statement in 1997, concepts such as qi "are difficult to reconcile with contemporary biomedical information."
