How It Works

Lithospermic acid and other organic acids are believed to be responsible for bugleweed’s activity. These acids decrease levels of several hormones in the body, particularly thyroid-stimulating hormones2 and the thyroid hormone thyroxine (T4).3 Bugleweed inhibits the binding of antibodies to the thyroid gland.4 These antibodies can cause the most common form of hyperthyroidism, Graves’ disease. All these actions may help explain bugleweed’s benefit in people with mildly overactive thyroids.

How to Use It

The German Commission E monograph recommends 12 grams of the whole herb per day.5 Intake of tincture should be limited to 12 ml three times a day. Bugleweed is often combined with other herbs used to treat mildly overactive thyroid function, including lemon balm(Melissa officinalis) and gromwell (Lithospermum ruderale).
