An Introduction to Bugleweed

Posted by: Sina Ghaboussi | Sep 02, 2010

Bugleweed, also known as Lycopus virginicus, is from the mint family and is found in nature in very wet areas in North America and throughout Europe. The leaves and flowers from this plant are used traditionally for the treatment of cough and as a sedative. Bugleweed is currently used in treating mild hyperthyroidism.

The active elements in bugleweed are lithospermic acid and other organic acids. These acids decrease levels of many hormones in the body including thyroid-stimulating hormone and thyroid hormone thyroxine. Bugleweed also inhibits antibodies that can bind to the thyroid gland causing Graves’ disease, the most common form of hyperthyroidism. These acids activities can explain bugleweed’s use in the treatment of mild hyperactive thyroid.

Bugleweed supplements should be taken as directed by the manufacturer. The German Commission E monograph recommends 1 to 2 grams of the whole herb per day or it has been taken 1 to 2 ml of the tincture three times per day. It can be found combined with other herbs also used for hyperactive thyroid such as lemon balm and gromwell. The side effect from excessive intake is a harmful decrease in thyroid function. Since thyroid disease is a serious condition, bugleweed should be used only under the supervision of a health care professional. People with hypothyroidism, pregnant women and breast feeding mothers should not use bugleweed.
