The only real treatment for thyroid disease, whether hypothyroidism, hyperthyroidism or any other condition of thyroid gland, is cleansing of the system and adoption of a rational diet thereafter, combined with adequate rest and relaxation. To begin with, juices of fruits such as orange, apple, pineapple, and grapes may be taken every two or three hours from 8 am to 8 pm for five days. The bowels should be cleaned daily with lukewarm water.
