## What is it made of?

### Mineral/Elemental Profile

- **Primary component:** Mercury-based preparation (Parada) with herbal processing
- **Note:** Restricted use — requires strict Shodhana protocols and expert supervision

**Analytical Methods:** AAS/ICP-MS (heavy metals), XRD, Namburi phased spot test

## Dosage forms and preparation

**Dosage Forms:** Fresh juice (primary form), Concentrated juice, Syrup, Panak (medicated beverage), Freeze-dried juice powder, Effervescent tablets

**Standard Dosage:** 10-20 mL fresh juice diluted with water, 1-2 times daily; 5-10 mL concentrated juice; reconstituted freeze-dried powder equivalent to 15 mL fresh juice

**Bioavailability:** Liquid form provides fastest absorption of organic acids and vitamin C. [Citric acid](/glossary/compounds-c-d/#citric-acidcitric-acid) enhances mineral bioavailability by chelation. Flavonoid [glycosides](/glossary/compounds-g-l/#glycosides) in juice matrix show 30-40% better absorption compared to isolated compounds due to food matrix effect. Low pH of juice enhances iron absorption when consumed with iron-containing foods or supplements.

**Optimal Timing:** Morning on empty stomach diluted with warm water for digestive stimulation; before meals for appetite; with meals for iron absorption enhancement; as needed for nausea

**Standardized Extract:** Cold-pressed juice with minimum 6% [citric acid](/glossary/compounds-c-d/#citric-acidcitric-acid) and 40 mg/100 mL ascorbic acid. Vacuum concentrate (5x) with standardized organic acid profile. Freeze-dried powder reconstituting to original juice characteristics.

**Shelf Life:** Fresh juice: 24-48 hours refrigerated, 6-8 hours at room temperature. Pasteurized juice: 6 months at 2-8 deg C. Concentrate: 12 months. Freeze-dried powder: 24 months. Effervescent tablets: 24 months.

**Storage:** Fresh juice at 2-8 deg C immediately after extraction. Concentrate in glass or lined containers at cool temperature. Freeze-dried powder in moisture-proof, nitrogen-flushed sachets below 25 deg C. Effervescent tablets in aluminum-foil tubes with desiccant cap.

**Marker Compounds:** Citric acid, Ascorbic acid, [Hesperidin](/glossary/compounds-g-l/#hesperidin), [Naringin](/glossary/compounds-l-o/#naringin), [Limonene](/glossary/compounds-g-l/#limonene) (trace volatile), Malic acid, [Potassium](/glossary/compounds-o-q/#potassium) citrate

### Extraction Methods

- Fresh mechanical juice extraction (cold press preferred)
- Centrifugal separation and clarification
- Vacuum concentration for shelf-stable concentrate
- Spray drying with maltodextrin (30-40%) for powder
- Freeze drying for premium powder retaining volatile aroma
- Pasteurization (flash, 72 deg C/15 sec) for microbial safety

### Synergistic Combinations

- [Saindhava Lavana](/herb/saindhava-lavana/)/Rock salt (digestive and electrolyte)
- Shunthi juice (anti-emetic and digestive)
- [Madhu](/herb/madhu/)/Honey (sore throat and cough)
- [Ajwain](/herb/ajwain/) (carminative combination)
- [Pudina](/herb/pudina/)/Mint (cooling digestive)
