Not so ! I know for a fact they work they are called ionic foot baths! In fact in New York city plumbing companies send thier employees who receive large amounts of toxins in thier work environment to these clinics that offer this service to prevent them from becoming ill, as many of thier co worker in the past have!
A color chart can even tell you what type of toxins you are releasing and these colors coincide with the toxins they have been exposed to! Your chemistry education may be little more then establishment propaganda!
