Leonurus japonicus (Yi Mu Cao) possesses multiple therapeutic effects, including promoting blood circulation and regulating menstruation, promoting diuresis and reducing edema, clearing heat and detoxifying, resolving blood stasis and relieving pain, and nourishing the blood while facilitating its smooth flow. By leveraging its herbal properties, it helps unblock qi and blood circulation within the body and specifically alleviates various stasis-related discomforts commonly experienced by women. It must be used only under the guidance of a qualified healthcare provider. Individuals experiencing abnormal bleeding should seek prompt medical evaluation.

1. Promotes Blood Circulation and Regulates Menstruation: This herb effectively resolves blood stasis and qi stagnation in the uterus, improving symptoms such as dysmenorrhea, scanty menstrual flow, and delayed menstruation caused by impaired blood flow. It helps regulate menstrual disorders stemming from qi and blood stagnation and supports regular, predictable menstrual cycles.

2. Promotes Diuresis and Reduces Edema: It facilitates water metabolism in the lower jiao (lower abdomen), alleviating edema of the limbs and abdominal fluid retention associated with blood and qi stagnation. By unblocking pathways for fluid transport, it reduces the sensation of distension and fullness caused by internal accumulation of dampness and fluid.

3. Clears Heat and Detoxifies: Its cooling nature disperses accumulated heat and eliminates toxins resulting from blood stasis and heat accumulation. It improves skin abscesses and swellings, as well as discomfort in the lower jiao due to damp-heat obstruction, and clears internal pathogenic heat generated by stasis.

4. Resolves Blood Stasis and Relieves Pain: It dissolves congealed blood and alleviates stabbing pain in the lower abdomen or postpartum pain caused by blood stasis. By unblocking meridians and restoring smooth flow of qi and blood, it mitigates persistent pain associated with stasis.

5. Nourishes the Blood While Facilitating Its Flow: It gently promotes blood circulation without depleting yin or blood, balancing both blood-activating and blood-nourishing actions. It improves sallow complexion and general sluggishness of qi and blood circulation resulting from concurrent blood deficiency and stasis.

When using Leonurus japonicus, dosage must be carefully controlled. It is contraindicated during pregnancy and should never be taken without professional supervision. To support treatment efficacy, avoid excessive intake of raw, cold, or chilling foods; maintain regular sleep-wake patterns to harmonize qi and blood; and combine it with mild, nourishing foods to minimize potential irritation to the internal organs.
