Motherwort is a mint with dull green, hairy leaves and an intensely bitter taste. The botanical name Leonurus refers to a fanciful resemblance of the leaves to a lion’s tale. One rather odd Hindu tale relates that if you make a tea of motherwort and add it to the laundry when you wash your socks and underwear, you will bring peace to your home. Motherwort is used for heart conditions, including heart failure, irregular heartbeat, fast heartbeat, and heart symptoms due to anxiety. It is also used for the absence of menstrual periods, intestinal gas (flatulence), and over-active thyroid (hyperthyroidism). Some people apply motherwort directly to the skin for itching and shingles. The seeds of two of the species are used to improve eyesight and as a general tonic. Motherwort might slow down the heart and thin the blood. It might also stimulate uterine tone and blood flow.
