Si Wu Tang

Four Substances Decoction

Nourish Blood • Regulate Menstruation • Harmonize the Blood • Restore Vitality

Si Wu Tang is one of the most fundamental Blood-nourishing formulas in Chinese medicine and is often considered the cornerstone formula for Blood deficiency patterns. First recorded in the Tai Ping Hui Min He Ji Ju Fang (Imperial Grace Formulary of the Tai Ping Era), it represents the classic approach to rebuilding Blood while maintaining healthy circulation.

Unlike formulas that only tonify, Si Wu Tang combines nourishment with movement. It replenishes Blood while ensuring that circulation remains smooth, preventing stagnation from developing as the body rebuilds its reserves.

When patients present with dizziness, pale complexion, scant menstruation, dryness, fatigue, or signs of Blood deficiency, Si Wu Tang is often one of the first formulas practitioners consider.

Beyond traditional deficiency patterns, this formula has become one of the most important prescriptions in gynecology, fertility support, recovery after blood loss, and cases where restoring healthy Blood physiology is central to treatment.

• Blood deficiency
• Dizziness
• Pale complexion
• Scant menstruation
• Irregular menstruation from deficiency
• Fatigue
• Dryness
• Weak circulation

• Recovery after illness or blood loss
• Deficient Blood affecting the Liver

Clinical Pearl

Si Wu Tang is one of the classic formulas every practitioner associates with the phrase “nourish the Blood.” Its hallmark indication is a patient whose tissues, cycles, and vitality lack sufficient Blood nourishment—often reflected through paleness, dizziness, dryness, or menstrual irregularity.

Its brilliance lies in its balance between replenishment and movement. A purely tonifying approach can sometimes create stagnation, while a purely moving approach can further deplete. Si Wu Tang addresses both needs by building Blood while maintaining healthy circulation.

For practitioners, Si Wu Tang remains the essential foundation formula for women’s health, fertility support, and any case where restoring the quality and abundance of Blood is central to healing.
