The thyroid gland controls how quickly the body uses energy, makes proteins, and controls how sensitive the body is to other hormones. The most common problems of the thyroid gland consist of an overactive thyroid gland, referred to as hyperthyroidism, and an underactive thyroid gland, referred to as hypothyroidism.

More About Herbalist & Alchemist

All H & A Formulas designed by David Winston, company founder, Herbalist (AHG), ethnobotanist, internationally known lecturer and author, who, for over 40 years has been studying, practicing, teaching and researching Cherokee, Chinese and Western herbal medicine. ENERGETICALLY BALANCED - Traditional practitioners generally use herbs in formulas. Each herb in every one of H&A formulas is selected by David not only for its own energetics, but also for how it will act in combination with other herbs in the formula.
CLINICALLY USED - All of the formulas have been used safely and effectively by David and many other practitioners--many of them for over 20 years.
RESPECTING TRADITION - They've been crafting the highest quality herbal products since 1982 by adhering to standards rooted in the practices of ancient guilds of alchemists. Species authentication by trained botanists and hand garbling of every raw material shipment are hallmarks of their BIO-SPECIFIC(tm) process.
USING THE WHOLE PLANT - The whole is always greater than the sum of its parts. Like the old masters, they believe that all the elements of the plant are essential in making herbal preparations. In ancient times alchemists pursued the quest of true knowledge of nature. Herbalist and Alchemist believe that all the elements of the plant are essential in making herbal preparations. Thus, one of the major differences between H & A and other herbal companies is their unique whole plant extraction process. Extracts are made with the finest ingredients: organically grown or conscientiously wildcrafted herbs, pure grain alcohol U.S.P., distilled water & when appropriate, vegetable glycerin U.S.P. or organic apple cider vinegar. Each extract is formulated according to the herb's distinct chemical makeup and made using Spagyric (alchemical) processes which give them a higher mineral & energetic content than found in other extracts.
Sometimes defined as "the transformation of common substance into vital essence," alchemy is based on true knowledge of nature. They combine ancient alchemical traditions with modern science to make exceptionally high-quality herbal products.
