Synopsis

Source of validity: Traditional
Rating (out of 5): 2

American Bugleweed (Lycopus americanus) has a history of traditional use as an herbal remedy for conditions related to the thyroid gland, particularly for mild hyperthyroidism (overactive thyroid) symptoms such as palpitations and mild anxiety. Traditional herbalists in North America and Europe have employed both American and related European bugleweed (Lycopus europaeus) for their purported ability to reduce thyroid hormone levels and manage symptoms of Graves’ disease and other forms of hyperthyroidism. The mechanism is believed to involve interference with thyroid-stimulating antibodies and inhibition of thyroxine synthesis, though this is primarily based on traditional herbal literature and some limited in vitro and animal studies.

Scientific evidence for these effects is limited and mostly derived from the related European species. Only a few small clinical studies and laboratory investigations suggest potential for mild thyroid-suppressing effects, but these studies are neither large nor robust enough for definitive conclusions. No major clinical trials exist for American bugleweed specifically, and safety data are also sparse. Thus, while bugleweed’s use in supporting thyroid health—specifically for hyperfunction—has traditional precedent, scientific validation remains weak, and it should not substitute for medical management of thyroid disorders.
