Note: Glechoma hederacea (ground ivy) should not be confused with Hedera helix (English ivy), although the species have similar common names.

Background

Ground ivy belongs to the Lamiaceae family, which includes mints and herbs such as rosemary, pennyroyal, spearmint, basil, catnip, and thyme. Ground ivy is found in dams and shady places, especially in thickets, in Canada, most of the United States, the United Kingdom (except Scotland), Europe, northern Asia, and Japan.

Traditionally, ground ivy has been used for tinnitus, catarrh, diarrhea, bile disorders, hemorrhoids, and as a tonic. Before hops were available in the early 16th Century, the British used ground ivy to clarify beer. During the Tudor period, it was used to preserve beer for sea voyages. Some old English recipes flavored jam with ground ivy and added young spring leaves to oatmeal, soups, and vegetables. In the early 20th Century, ground ivy tea was used in Britain as a cure-all, and was frequently used for tuberculosis and as an antidote for lead poisoning. The stems of the plant were also made into wreaths for the dead.

Today, ground ivy is often a recommended addition to compost heaps because of its high iron content. Animal and laboratory studies indicate that ground ivy may be useful for its antibiotic or anti-inflammatory effects. However, ground ivy is considered by some local governments to be a bothersome and aggressive weed in Europe and North America. There are currently no high quality studies available on the medicinal applications of ground ivy.

Evidence

DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Tradition

WARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (over 18 years old)

There is currently no proven safe or effective dose for ground ivy. Traditionally, 2 grams of the dried plant or 2-4 milliliters liquid extract (1:1 in 25% alcohol) three times daily has been used. One cup of tea (2-4 grams dried plant steeped in 150 milliliters boiling water for 5-10 minutes) three times daily has also been used.

Crushed ground ivy leaves have been applied to the skin, but information on dosing or duration is unavailable.

Children (under 18 years old)

There is currently no proven safe or effective dose for ground ivy in children and use is not recommended.

Safety

DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.

Allergies

Avoid in individuals with a known allergy or hypersensitivity to ground ivy (Glechoma hederacea), or other members of the Lamiaceae family, including mint, rosemary, basil, oregano, thyme, and lavender.

Side Effects and Warnings

There are very few reports of ground ivy and its adverse effects. Pulegone, a constituent of ground ivy, may be toxic to the liver. Patients with compromised liver function should use ground ivy with caution. Ground ivy may also induce seizures, produce swelling of throat, and labored breathing. Use cautiously in patients with impaired kidney function, as ground ivy oil may irritate the kidneys.

Pregnancy & Breastfeeding

Ground ivy is not recommended in pregnant or breastfeeding women due to a lack of sufficient available scientific evidence.

Interactions

Interactions with Drugs

Ground ivy may contain high amounts of vitamin C (ascorbic acid), which may decrease the effect of warfarin (Coumadin®) and similar anticoagulants ("blood thinners"). The high vitamin C content may also enhance the body's absorption of iron, increase the levels of aspirin in the blood, decrease fluphenazine levels in the blood, or increase the concentration and effect of birth control pills. Consult with a qualified healthcare professional, including a pharmacist, before taking ground ivy.

Interactions with Herbs & Dietary Supplements

Ground ivy may contain high amounts of vitamin C (ascorbic acid), which may decrease the effect of some anticoagulants ("blood thinners"). The high vitamin C content may also enhance the body's absorption of iron. Individuals taking iron supplements or multivitamins should consult with a qualified healthcare professional, including a pharmacist, before taking ground ivy.

Ground ivy also contains pulegone, which is potentially toxic to the liver. This chemical compound may interact with pennyroyal, which also contains pulegone. Caution is advised.
