Scientific: Lycopus americanus [WikiPedia]
Composition: Lycopus contains rosmarinic acid, a phenolic compound derived from caffeic acid and found in several other Lamiaceae plants, all indicated historically for the symptoms of hyperthyroidism. Rosmarinic acid, and the related lithospermic and chlorogenic acids, may exert an antithyroid effect in cases of hyperthyroidism.
Appearance: Not to be confused with Carpet bugle or common bugle (Ajuga virginicus), bugleweed is a marshland native to Europe and naturalized to the United States in the 17th century by colonists who grew it for its beneficial qualities. The herb is also known as gypsywort or waterhorehound. It bears clusters of white, bugle-like flowers where stems connect to leaves. It is of the lamiaceae family, but is often referred to as the “odorless mint”. The botanical name Lycopus refers to the resemblance of the cut leaf to a wolf’s paw, which also explains the plethora of common names in many languages referring to wolves.
Parts Used: Dried leaves and flowers.
Common Uses: Bugleweed’s reputation for treating an over-active thyroid aka hyperthyroidism is exciting, even if hyperthyroidism is more common in cats than dogs. Hyperthyroidism shouldn’t be confused with hypothyroidism. While hyperthyroidism describes an overactive thyroid, hypothyroidism occurs when the thyroid gland underperforms. Nevertheless, dogs that do struggle with this condition can see some serious results with bugleweed. Bugleweed might reduce the body’s production of thyroid hormone. Bugleweed also seems to reduce the release of the hormone prolactin, which might help relieve breast pain. Bugleweed is used to lower high levels of thyroid hormones (hyperthyroidism). It is also used to treat premenstrual syndrome; breast pain; nervousness; trouble sleeping (insomnia); and bleeding, especially nosebleeds and heavy bleeding during menstruation.
Dogs with hypothyroidism, a condition caused by an underactive thyroid gland, should NEVER take bugleweed.
