Sujok therapy is a Korean drug-free healing modality developed by Prof. Park Jae Woo in the 1980s, which uses specific stimulation points on the hands ('Su') and feet ('Jok') to treat ailments. It acts as a comprehensive, natural system that maps the entire body to these, allowing for safe, effective, and often rapid relief of pain and various illnesses through acupressure, needles, or seed therapy.
