Leonurus japonicus root
Free herbal dosage calculator — adult & child doses by weight.
Yi Mu Cao root contains active compounds including stachydrine, leonurine, alkaloids, flavonoids, and iridoids that promote blood circulation and stimulate uterine contractions. These bioactive constituents help break up blood stasis and move blood through the body's channels. In Traditional Chinese Medicine, this root is specifically valued for its ability to address abdominal masses and uterine blood stasis conditions by invigorating blood flow (Evidence Level C).
Yi Mu Cao root has blood-thinning properties and may interact with anticoagulant and antiplatelet medications such as warfarin, aspirin, or clopidogrel. Combining this herb with blood thinners may increase bleeding risk. Due to its effects on blood circulation and uterine tissue, consult a qualified healthcare provider before using Yi Mu Cao root alongside any prescription medications (Evidence Level C).
The standard adult dosage for Yi Mu Cao root is 9–30 grams of dried root prepared as a decoction. This dosage range reflects Traditional Chinese Medicine practice for addressing blood stasis and abdominal masses. Dosage should be adjusted based on individual condition and constitution under guidance from a qualified TCM practitioner. Evidence for specific dosing protocols is limited (Evidence Level C).
Yi Mu Cao root is unsafe during pregnancy and is strongly contraindicated. The herb stimulates uterine contractions and promotes blood movement, which can trigger miscarriage or premature labor. Women who are pregnant or attempting to conceive should avoid this herb entirely. In TCM, Yi Mu Cao root is specifically used for postpartum conditions precisely because of its uterine-stimulating properties (Evidence Level C).
Yi Mu Cao root is used in Traditional Chinese Medicine primarily for abdominal masses, blood stasis conditions, and postpartum recovery. Unlike the aerial parts of motherwort, the root specifically targets uterine blood stasis and is classified as a blood-moving herb. It may be prescribed for conditions involving stagnant blood, menstrual disorders related to blood stasis, and recovery after childbirth (Evidence Level C).
