Motherwort - Cover


Motherwort (Leonurus cardiaca), commonly known as lion’s tail, belongs to the mint family. This plant normally grows 4 to 5 feet on areas where soils have been previously used for growing other plants or on those artificially placed-over soils. It also grows wildly on riverbanks and floodplains. This plant prefers partial exposure to sunlight and moist and fertile soil. In some countries, this plant is propagated for its medicinal properties and uses.

The History Of Motherwort

There is a long historical account of the medicinal use of Motherwort. This plant is said to have likely originated from both central and northern Asia, specifically in Japan and Siberia. It was later introduced to Europe in about the 17th century and subsequently to Northern America. Presently, this variety of mint has flourished largely in Canada and the continent of the United States.

  • In Ancient Greece, it has been indicated for use on many female reproductive issues. Many records mention the herb was used for heart ailments and anxiety among pregnant women.
  • Ancient China also claims historical use of the herb. It was traditionally used for menstrual disorders and varied gynecological issues among Chinese women. Motherwort was recorded as the highest grade plant in one of the earliest pharmacological manuscripts entitled “Shennong Bencao Jing” for its non-toxicity.
  • In 1652, Nicholas Culpeper published a book, “The Complete Herbal.” The book contains a useful description and uses of motherwort, which modern herbalists keep on citing. Culpeper talked about how the herb makes women calm, and how it positively affects many mothers after child delivery. Thus, its name Motherwort has been derived.
  • In 1869, William Cook, a known physiomedicalist at that time, also wrote about the herb as a good way to calm the nerves and to relieve muscle spasms, particularly the muscle found in a person’s bowel wall. Additionally, he specifically indicated that the herb is a cure for nervousness, chest pains related to palpitations, and various menstrual pains or cramps among women.
  • In 1919 and 1922, Finley Ellingwood and Harvey Wickes Felter consecutively published their books, The American Materia Medica and Eclectic Materia Medica. They have described Motherwort as “nervine, antispasmodic, laxative, and emmenagogue.”
  • In 1998, according to Moerman, some native and indigenous tribes in America used the herb brew as a gynecological relief for “female ills.” Meanwhile, the Cherokee and Iroquois used it as gastrointestinal help to promote digestion and as a calming aid for nervousness. The Cherokee specifically used this as a tonic for fainting.

Where This Plant Is Found

Motherwort is perennial and is widely popular in Asia and the southeastern part of Europe. However, it is considered invasive in the United States. Although the herb is uncommon in the southern part of Illinois, it is widespread in the central and northern areas of the state.

Currently, Motherwort is now growing in most parts of the world. It is usually found on woodland borders, among the groups of other plants in the bushes, underneath the trees, wetlands or moist lands, and underneath shady areas.

How to Identify Motherwort

It stands on an erect or straight orientation, crowned with dark green and a sort of compound leaves, resembling that of a maple leaf. The leaves grow opposite from one another on the stem.

Uniquely, its petioles or stalks that spring from the stem and leaf sprout longer than the flowers. Its flowers are spiky and have five-pointed sepals or calyx.

How To Grow Motherwort

Motherwort propagates easily by seeding or through its rhizomes.

To begin growing Motherwort using its seeds, cold stratification is advised. Cold stratification is a simple method used to trick the seeds to feel as if it is already experiencing winter. The method first entails soaking the seeds for a period of at least 10 hours to 24 hours or a day. After this step, place the seeds on the sand and peats, or compost in a zipped bag. Place it inside the refrigerator for 10 days. While the seeds are in the refrigerator, regularly check to make sure that the mix does not dry up. Spritz the mixture with water if moist is absent and if it has gone dry.

After 10 days, the seeds are ready for planting in a plot. Prepare the area by softening the topsoil using a garden hoe or any cultivating garden tool available. Space the planting 2 to 3 feet apart from each other. The seeds should be covered with at least 1/8-inch soil. Normally, one would just wait a week for it to sprout.

If you bought the seed product from a store, read the label to see if it already went through the cold stratification method before proceeding any further.

If you do not want the trouble of doing the cold stratification method, sowing the seeds in late fall is recommended. Planting during this time will help the plant to sprout and thrive easily.

Once the Motherwort matures, it quickly spreads through its rhizomes. You can simply unearth the surrounding soils where the new sprouts grow. It can be separated or gently cut so that you can plant it in a new area. When transferring, the hole should be double the length of its roots or rhizoids.

Water the young plants accordingly. Ideally, it thrives well on soils with good alkalinity of at least 7.7 pH. As it matures, there is a rare need for watering the plant as it becomes stable, sturdy, and drought-resistant. Motherwort is rarely affected by pests and diseases.

To prevent the plant from seeding, you can just cut the stems 2 to 3 inches after the flowering stage.

May I offer a gentle correction? This article mentions that the heart is smooth muscle. It is actually STRIATED muscle. The blood vessels, however, are lined with smooth muscle.

I’ve been waiting to see herbs that help pregnant mothers, or mother’s to be. In particular, I have a 60# canine who was diagnosed with chronic inflammation of the uterus. I’ve collected stinging nettle for it’s potential use. Would motherwort be a possibility? Can you make any other recommendations?

Wonderful article! Thank you for including so much information all in one place. And thank you to Grama PEI for the note. ‘Hoping Marsha’s canine is better soon. I am interested in knowing what works.

Just a quick correction. Motherwort is known as lion’s HEART, not lion’s tail. Leonurus = lion and cardiaca = heart.
