History/Folklore: Motherwort’s name derives from the herb’s strength in treating many female issues. Historically it has been used in China to prevent pregnancy. The Ancient Greeks gave it to women to reduce anxiety. The herb’s common name Lion’s Ear comes from the leaf’s lion tail shape, as well as the plant’s ability to strengthen the heart, making one strong and brave like a lion.

There is an old tale of a town whose waters flowed through banks of motherwort which caused the residents to live to be 130 years old.

The 17th-century English herbalist, Nicholas Culpepper, used the herb for treating depression. The herb was also often used in Europe to help treat cattle for a variety of diseases.

Unlike other herbs in the mint family, motherwort is a bitter herb without the fragrance and flavor of many mint family plants. The taste is often softened by the use of honey, lemon, or other herbs to help balance the herb’s strong bitter flavor.

Motherwort contains heart-healthy flavonoids and glycosides. That help improve circulation and regulate the heartbeat. It is especially useful for those who are anxious and carry a lot of tension in their body. As a heart tonic, it is used to treat palpitations, mild heart irregularity, hypertension, and to strengthen the heart.

It is an herb that is useful for treating the emotional body in times of grief or sorrow. The plant’s common name, Lion’s Heart, hints at this function. The herb is known for lending strength to those who are experiencing intense vulnerability and stress-related symptoms.

The compound, leonurine, found in motherwort, is known to help relax blood vessel walls helping to lower blood pressure and improve heart rate. This same compound also promotes uterine contractions that can both encourage childbirth and promote menstruation.

In China, motherwort is considered the premier herb for strengthening the heart and promoting longevity. It is recognized for its blood-moving and cleansing ability. This includes the ability to reduce masses in the blood that can cause unwanted clotting and heart attacks or strokes. It is also often used for treating a wide range of female disorders caused by hormonal shifts or blood stagnation.

Motherwort seeds can also be used medicinally. They are slightly sweet and cold. They are generally used to break up blood clotting or masses and are considered more astringing and tonifying than the fresh or dried herb.

Motherwort has a long history as a guard against dark spells or repelling negative energies and bad luck. In occult worlds, the herb is said to have powers that work through energies to help heal and exorcize evil energies or entities. It is valued as a highly protective herb and is associated with immortality and spiritual healing.

Another member of the mint family, L. leonurus, is a different species, native to South Africa. It is also sometimes called lion’s tail and is not to be confused with motherwort (Leonurus cardiac or Leonurus artemisia). This African relative is sometimes also called wild dagga, and is used for among other healing properties, its mild psychoactive compounds that have a similar, but milder, effect as cannabis.

Motherwort flowers have been added to beers to add flavoring.
