Toki-shakuyaku-san (Angelica and Peony Powder / TJ-23): Ligustilide, Microvascular Pelvic Flow & Gynecological Dysmenorrhea

The Cornerstone of Kampo Women's Health
In Japanese obstetrics and gynecology (Sanfujinka), where Kampo formulas are routinely integrated into clinical practice, Toki-shakuyaku-san (Kampo Code: TJ-23; Chinese: Dang Gui Shao Yao San) is recognized as the quintessential formula for women presenting with constitutional chilliness (Hiesho), pale complexion, dizziness, fluid retention, and painful menstrual cramping.Originating in the Jingui Yaolue (Essential Prescriptions from the Golden Cabinet), this classical six-herb prescription addresses a dual pathology: Blood Deficiency with Stagnation (Ketsu-kyo / Oketsu) coexisting with Fluid Accumulation (Sui-doku).
The balanced prescription unites:
- Japanese Angelica Root (Toki / Angelicae Acutilobae Radix) (3.0g)
- Peony Root (Shakuyaku / Paeoniae Radix) (4.0g)
- Cnidium Rhizome (Senkyu / Cnidii Rhizoma) (3.0g)
- Atractylodes Rhizome (So術 / Byakujutsu) (4.0g)
- Poria Sclerotium (Bukuryo) (4.0g)
- Alisma Tuber (Takusha / Alismatis Rhizoma) (4.0g)
Phytochemical Spectrum & Active Constituents
| Botanical Pillar | Key Bioactive Markers | Molecular Target | Clinical Gynecological Action |
|---|---|---|---|
| Toki & Senkyu | Z-Ligustilide, Butylidenephthalide, Ferulic acid | Uterine vascular smooth muscle endothelin-1 | Promotes vasodilation, clears microvascular pelvic stagnation |
| Shakuyaku | Paeoniflorin, Oxypaeoniflorin | Uterine myometrial calcium channels | Relaxes spastic menstrual cramping and pelvic discomfort |
| Byakujutsu & Bukuryo | Atractylodin, Pachymic acid | Renal tubular epithelial water channels | Resolves cyclic premenstrual fluid retention and pedal edema |
| Takusha | Alisol triterpenoids | Aquaporin-4 (AQP4) water pores | Drains heavy, sluggish pelvic fluid without dehydrating tissues |

Pharmacological Actions in Gynecological Care
- Pelvic Microvascular Perfusion: Clinical transvaginal color Doppler ultrasound studies in Japan have verified that Toki-shakuyaku-san significantly reduces resistance in the uterine and ovarian arteries, warming cold pelvic extremities.
- Resolution of Cyclic Premenstrual Edema: The tripartite combination of Alisma, Poria, and Atractylodes drains stagnant lymphatic fluid from the lower extremities and pelvis, relieving the heavy, water-logged sensation common before menstruation.
Standardized Administration & Posology

- Standard Extract Dosage: 7.5 grams daily of standardized extract granules (Tsumura TJ-23), taken before meals in 2 to 3 divided doses with warm water.
- Duration: Typically prescribed continuously across 2 to 3 menstrual cycles to systematically rewrite constitutional vascular reactivity and resolve chronic Hiesho.
Safety & Considerations
- Exceptional Safety Record: Unlike harsher blood-invigorating formulas (such as Keishi-bukuryo-gan), Toki-shakuyaku-san is gentle and has a celebrated historical safety record, even during early pregnancy under clinical guidance.
- Mild GI Sensitivity: Occasionally, sensitive individuals may experience mild loose stools due to the rich Angelica content; taking the formula with warm ginger tea mitigates this.
