The Effects of Motherwort

Motherwort is a herb native to Asia, now grown worldwide, that has been used for centuries as a blood thinner, muscle relaxant and in other applications. The herb is also known as lion's tail, heartwort, leonurus and throwwort. When administered properly or included as an ingredient in other medications, motherwort has a broad range of beneficial effects but can have harmful side effects if used incorrectly.

Common Uses

Health-Care-Tips.org lists motherwort as beneficial in treating irregular heartbeat, specifically when nervousness causes the heart rate to increase, by reducing blood pressure and maintaining the heartbeat. It is sometimes used as a uterine tonic and to treat nervous conditions, improve circulation, lower blood lipids and reduce platelet aggregation. It is also used in supportive therapy for hyperthyroid activity. According to the Encyclopedia of Alternative Medicine, these properties are the result of leonurine and stachydine present within the herb. Modern herbalists also prescribe it as a sedative and sleep aid due to its calming effects.

Menopause, Menstruation and Childbirth

Motherwort may regulate abnormal menstrual cycles when taken on a regular basis. Its antispasmodic effects can be beneficial in restoring uterine muscle tone after childbirth, and its relaxing properties have been applied to treat the physical and emotional symptoms of premenstrual syndrome and menopause. It is an ingredient in the menopause medication Peritrol, in which it normalizes uterine musculature, which can become spasmodic and uncontrolled during perimenopause. Motherwort is also used to treat amenorrhea, vaginal dryness and night sweats, and it can relieve heart palpitations. It can also be taken regularly to prevent hot flashes or at the onset of a hot flash to provide relief.

Side Effects

Some side effects of an excess of motherwort include diarrhea and stomach irritation. In more severe cases, uterine bleeding can occur. Some individuals report an increased sensitivity to light after taking motherwort. The leaves can have an irritating effect and cause inflammation when in contact with the skin of some individuals. Taking motherwort during pregnancy can lead to uterine contraction and potential miscarriage.
