Bugleweed is used to relieve aches and pains. It contains compounds that contract the tissues of the mucous membranes and reduce fluid discharges. Bugleweed is also used as a treatment for enlargement of the thyroid gland because bugleweed tea contains certain compounds that have the ability to reduce specific hormones in the body such as the thyroid hormone thyroxine which is often overproduced in the body by those who suffer from hyperthyroidism. This compound also keeps antibodies from binding to and “burning out” cells in an overactive thyroid gland. By moderating estrogen levels, bugleweed relieves cyclic breast pain in women. Like digitalis, it works to lower the pulse, as well as equalize circulation. One of its most common uses is soothing the irritations of a cough.
