People are more worried than ever before about the toxicity of the world around them. This may be one reason for a greater interest in detoxification products and diets.
Dr. Andrew Weil recommends that people trust their body's own means of detoxification. Common sense things like drinking lots of water, eating well and exercising go a long way toward health.
He does suggest milk thistle as a means of detoxification. But he is not convinced that there is great value in buying detoxification products in general.
"Dr. Andrew Weil, M.D., was born in Philadelphia in 1942, received an A.B. degree in biology (botany) from Harvard in 1964 and an M.D. from Harvard Medical School in 1968. After completing a medical internship at Mt. Zion Hospital in San Francisco, he worked a year with the National Institute of Mental Health before writing his first book, The Natural Mind. From 1971-75, as a Fellow of the Institute of Current World Affairs, Dr. Weil traveled widely in North and South America and Africa collecting information on drug use in other cultures, medicinal plants, and alternative methods of treating disease."
