Thyroid Calming features Bugleweed extract prepared from the flowering aerial portions of Lycopus spp. plants. It also features Motherwort extract prepared from the leaf and flowering tops of Certified Organic Leonurus cardiaca plants grown on Herb Pharm's own farms in southern Oregon.

The herb is extracted in small batches with Certified Organic cane alcohol for potency and to maintain the balance of phytochemicals as they exist in the plant. Herb Pharm assures herb identity via macroscopic and organoleptic analysis, then confirms it through methods such as HPTLC fingerprinting specific to each herb. The formula is easily dispensed, taken in liquid form and added to water or other liquid.
