Goreisan Formula (Five Herb Hydroregulation / TJ-17): Alisol Triterpenes, Aquaporin Channel Modulation & Fluid Balance

The Pinnacle of Botanical Fluid Homeostasis

First recorded in the ancient Shanghan Lun, Goreisan is uniquely not a brute-force dehydrating diuretic. Unlike pharmaceutical loop diuretics that force water excretion through sodium depletion (risking dehydration and electrolyte collapse), Goreisan is a bidirectional hydroregulator: it drains excess water from edematous, congested compartments while simultaneously rehydrating dehydrated cells.

The five-herb botanical formula consists of:

1. Alisma Tuber (Takusha / Ze Xie) — Monarch herb (5.0g)


2. Poria Sclerotium (Bukuryo) (3.0g)


3. Polyporus Sclerotium (Chorei) (3.0g)


4. Atractylodes Rhizome (So術 / Byakujutsu) (3.0g)


5. Cinnamon Twig (Keihi / Gui Zhi) (2.0g)

Phytochemical Spectrum & Aquaporin Modulation

| Botanical Component | Key Bioactive Markers | Molecular Target | Clinical Hydroregulatory Action |
|---|---|---|---|
| Alismatis Rhizoma | Alisol A, B, B 23-acetate | Aquaporin-4 (AQP-4) & Aquaporin-1 (AQP-1) | Suppresses water influx across astrocytic and endothelial water pores |
| Polyporus umbellatus | Ergosterol, Polyporusterone A, B | Renal collecting duct sodium-potassium channels | Saluretic fluid drainage without potassium wasting |
| Poria cocos | Pachymic acid, Dehydrotumulosic acid | Cerebral astrocyte membrane fluidity | Quenches cellular swelling and osmotic stress |
| Cinnamomi Ramulus | Cinnamaldehyde, Cinnamic acid | Vascular endothelial TRPA1 channels | Promotes peripheral microvascular circulation, dispersing fluid |

Pharmacological Actions in Modern Medicine

1. Aquaporin-4 (AQP4) Channel Inhibition: Cerebral edema and weather-induced migraines often result from excessive water influx into astrocyte foot processes via AQP4 water channels. Goreisan selectively inhibits AQP4 upregulation, preventing brain swelling.
2. Chronic Subdural Hematoma Management: In Japanese neurosurgical clinics, Goreisan is widely prescribed post-operatively to prevent the recurrence of chronic subdural hematomas, demonstrating a statistically significant reduction in re-operation rates compared to conventional observation.

Standardized Clinical Administration

• Standard Extract Dosage: 7.5 grams daily of standardized extract granules (Tsumura TJ-17), taken before meals in divided doses with warm water.
• Pre-Emptive Dosing for Weather Headaches: For individuals sensitive to drops in barometric pressure (typhoons, approaching rain fronts), take a single dose of 2.5g at the first sign of barometric decline or sensory heaviness.

Safety & Considerations

• No Electrolyte Imbalance: Extensive clinical studies confirm that Goreisan does not alter serum sodium, potassium, or chloride levels, making it exceptionally safe for elderly patients.
• Safety in Pregnancy: Used historically for gestational edema with an exemplary safety profile.
