# Tanduliyaka

> Tanduliyaka is a substance used in the Ayurvedic materia medica. Polyphenols and flavonoids undergo extensive Phase II metabolism. The high dietary fiber content slows gastric emptying and may modulate absorption kinetics of co-administered drugs.

## What is it made of?

### Mineral/Elemental Profile

- **Primary component:** Mineral-derived preparation
- **Note:** Composition varies by specific preparation method

**Analytical Methods:** XRD, ICP-OES, SEM-EDS

## Dosage forms and preparation

**Dosage Forms:** Svarasa (fresh juice), Churna (powder), Kwatha (decoction), Capsule, Tablet

**Standard Dosage:** 10-20 mL fresh juice twice daily; 3-5 g powder twice daily; 50-100 mL decoction twice daily

**Bioavailability:** Betalains (amaranthine, isoamaranthine) show moderate oral bioavailability (~20-30%) with rapid absorption in the upper GI tract. [Polyphenols](/glossary/compounds-o-q/#polyphenols) and [flavonoids](/reference/flavonoids/) undergo extensive Phase II metabolism. The high dietary fiber content slows gastric emptying and may modulate absorption kinetics of co-administered drugs. Iron and calcium from the plant matrix have moderate bioavailability enhanced by vitamin C co-administration.

**Optimal Timing:** Before meals for hematinic effect; morning administration with honey or jaggery as traditional vehicle

**Standardized Extract:** Aqueous or hydroethanolic extract standardized to >0.5% total betalains (as amaranthine by UV-Vis at 538 nm); >2% total polyphenols (as gallic acid equivalent)

**Shelf Life:** Fresh juice: 24-48 hours refrigerated; Powder: 12 months; Capsules/Tablets: 24 months; Spray-dried extract: 24 months

**Storage:** Store in airtight, light-resistant containers at 15-25 deg C. Betalain-containing products require protection from light, heat, and humidity. Freeze-dried forms stored at 2-8 deg C for maximum stability.

**Marker Compounds:** Amaranthine, Isoamaranthine, [Rutin](/glossary/compounds-q-t/#rutin), [Quercetin](/reference/quercetinquercetin/), [Kaempferol](/reference/kaempferol/), beta-[Sitosterol](/glossary/compounds-q-t/#sitosterol), Gallic acid, Ferulic acid

### Extraction Methods

- Aqueous extraction (decoction)
- Hydroethanolic extraction (40-60% ethanol)
- Cold pressing for fresh juice
- Spray drying of aqueous extract
- Freeze drying for color-sensitive betalains

### Synergistic Combinations

- Amalaki (Emblica officinalis) - vitamin C enhances iron absorption from Tanduliyaka
- Shunthi - digestive enhancement and anti-inflammatory synergy
- [Guduchi](/herb/guduchi/) - [immunomodulatory](/reference/immunomodulatory/) potentiation
- Jaggery - traditional vehicle for hematinic formulations
