Tai Chi, or Tai Chi Ch’uan, means “supreme fighting” or “ultimate fists” in Mandarin. It is basically a form of martial art originating in China sometime around the 16th century. It has five known forms in existence today, though all are connected to each other without any drastic difference. During the 1970s, it was introduced in America and has been growing in popularity ever since. There have been no known side effects or harm caused by practicing Tai Chi in long term or short term.
