the body. The participant had a restricted diet, including large doses of vitamins and a teaspoon of salt, and spent at least an hour a day jogging in a rubberised suit. For some, this regimen lasted for months. The program was developed for use in Narconon, and was published in Hubbard's Technical Bulletins of Dianetics and Scientology as well as the book Clear Body, Clear Mind. Two other books describe the procedure, Purification: An Illustrated Answer To Drugs and Narconon New Life Detoxification Program: the effective purification program by L. Ron Hubbard. The term "Purification Rundown" is a trademark of the Religious Technology Center (the governing body of the Church of Scientology), though an RTC spokesman has denied any licensing arrangement with Narconon. Process The Purification Rundown usually takes several weeks. As well as spending time in saunas, people are required to do light exercise including calisthenics, treadmills, and other similar activities. The program consists of a course of doses of vitamins (niacin in particular), long periods in a sauna, exercise, and consumption of a blend of vegetable oils, in the belief that the subject will sweat out the toxins and replace the oils in the body's fatty tissues with the vegetable oil. Clear Body, Clear Mind recommends that participants maintain their normal diet throughout the procedure, supplemented with fresh vegetables. The program requires its participants to ingest the following at regular intervals: A multi-vitamin cocktail, the main ingredient of which is niacin. Clear Body, Clear Mind recommends initial doses of 100 mg, increasing to 5,000 mg over the course of the program. This contrasts with the medically recommended level of about 15 mg: larger doses can have severe, even potentially fatal side effects. The participant is told to expect toxic symptoms due to the release of poisons or radiation from their body fat. Mineral supplements, including calcium, magnesium, iron, zinc, manganese, copper, iodine and potassium. Up to half a cupful of pure oils per day. "CalMag", a drink which Clear Body, Clear Mind describes as a solution of calcium gluconate, magnesium carbonate and vinegar in water, in such proportions that the mix has twice as much elemental calcium as magnesium. This is taken up to three times per day. Enough liquids to replace the fluids lost in the sauna. Hubbard specified that each participant must complete a daily report form, listing the amounts of vitamins, minerals, Cal-Mag and other
