Oom Yung Doe (음양도; 陰陽道) is a line of Korean martial arts schools founded by John C. Kim (Grandmaster "Iron" Kim). In addition to teaching a broad range of physical movements and self-defense, the training also incorporates meditation, philosophy, and the use of herbal formulas and equipment. Some students describe substantial benefits including self-defense skills, mental and physical health, and improvements in conditions such as asthma, diabetes, rheumatoid arthritis, and blood pressure. Critics, however, accuse the school's founder and instructors of unethical behavior, charging large fees, and pressuring students to commit to long-term contracts. Beginning in the late 1980s, several TV and newspaper reports publicized these accusations, and described the school as a "cult." Kim and four of the organization's instructors were found guilty of conspiracy to commit tax fraud in 1995. Despite those issues, certain benefits of the training such as increased lung capacity and the healing of treatment-resistant back pain have been demonstrated to be effective in clinical settings; and there have also been several news reports publicizing some of the benefits described by the students.
