"BHT" is often used to refer to a set of diagnostic, prescribing, preparation and marketing practices including compounding (the preparation of custom-mixed hormones by a pharmacist, according to a prescription), saliva testing, and an emphasis on countering the effects of aging rather than relieving the symptoms of menopause. This compounded BHT package has been promoted by Suzanne Sommers, Oprah Winfrey and other proponents as safer and more effective than CHRT, though there is no evidence to support these claims. Compounded BHT has been marketed on the internet by pharmacies which make unfounded claims for its safety and its effectiveness for a variety of conditions.
