## Dosage forms and preparation

**Dosage Forms:** Churna (powder), Kwatha (decoction), Svarasa (fresh juice), Capsules, Tablets, Topical paste, Ointment

**Standard Dosage:** 3-6 g powder per day in divided doses; 50-100 mL decoction twice daily; 10-20 mL fresh juice

Mimosine undergoes partial hepatic first-pass metabolism. Co-administration with [piperine](/reference/piperine/) or lipid-based carriers can improve absorption of flavonoid [glycosides](/glossary/compounds-g-l/#glycosides) by 25-40%.

**Optimal Timing:** Before meals for GI indications; with meals for systemic anti-inflammatory effects; topical application 2-3 times daily on affected area

**Standardized Extract:** Standardized aqueous-ethanolic extract (10:1 concentration ratio), minimum 2% total flavonoids, 1.5% tannins (as gallic acid equivalents). Mimosine content controlled below 0.5% in oral formulations for safety.

**Shelf Life:** 24 months for powder in airtight containers; 36 months for tablets/capsules; 18 months for liquid extracts

**Storage:** Store below 25 deg C in airtight, light-resistant containers. Protect from moisture (relative humidity below 60%). Liquid extracts require refrigeration at 2-8 deg C after opening.

**Marker Compounds:** Mimosine, Gallic acid, [Quercetin](/reference/quercetinquercetin/), [Stigmasterol](/reference/stigmasterol/), Beta-[sitosterol](/glossary/compounds-q-t/#sitosterol), [Apigenin](/glossary/compounds-1-a/#apigenin), D-pinitol

### Extraction Methods

- Hydroalcoholic extraction (50-70% ethanol)
- Aqueous decoction
- Cold maceration

- Soxhlet extraction with methanol

### Synergistic Combinations

- [Ashwagandha](/herb/ashwagandha/) (stress and wound healing)
- [Haridra](/herb/haridra/) (anti-inflammatory synergy)
- [Guduchi](/herb/guduchi/) ([immunomodulatory](/reference/immunomodulatory/) potentiation)
