Bugleweed (Lycopus virginicus) is an herb that in the same family as mint and sage. It is commonly found in Eastern North American states. The leaves have pointed, serrated edges and are colored green and reddish-brown with small white flower clusters at the base of the leaves on the stem.

Traditionally, bugleweed was used to treat coughs and induce sedation. In modern times, bugleweed is used as a supplemental treatment for mild cases of hyperthyroidism and goiter.

Bugleweed can be used as supplemental treatment for the following:

  • Hyperthyroidism
  • Toxic goiter
  • Grave’s disease
  • Other hormonal imbalances
  • Contraception

How does it work?

Active compounds found in bugleweed include phenolic compounds. The exact mechanisms are not known; however, studies have shown that extracts of L. virginicus inhibit iodine metabolism and thyroxine release in the thyroid. This can explain its use in treating thyroid disorders.

It may also possess antigonadotrophic, anti-prolactin, and anti-glucagon effects. These properties make it a potential contraceptive and blood sugar regulator.
