# Avaleha

> Avaleha is a classical Ayurvedic avaleha, a semi-solid herbal confection. Avaleha (Sanskrit: ava-lih, "to lick"), also called Leha or Lehya, is the classical Ayurvedic semi-solid confection pharmaceutical dosage form.

**Avaleha** (Sanskrit: *ava-*lih, "to lick"), also called **Leha** or **Lehya**, is the classical Ayurvedic semi-solid confection pharmaceutical dosage form. It is the **kalpana** (preparation class) that encompasses [Chyawanprash](/formulation/chyawanprash/), Vasa Avaleha, Kushmanda Avaleha, Agastya Haritaki, Bilwadi Leha, Manibhadra Guda and the full family of medicated jams, pastes and electuaries.

## Definition

Per *Sharangadhara Samhita* Madhyama Khanda Chapter 8 — the canonical Avaleha Kalpana chapter — an Avaleha is a medicated paste prepared by combining:

1. A herbal **kashaya** (decoction) or **swarasa** (juice) base, reduced and cooked
2. A sugar/jaggery matrix cooked to defined **pakva** (consistency) stages
3. Fine **prakshep dravya** (aromatic powders) added at lukewarm temperature
4. Optional **sneha** (ghrita, taila) for lipid-mediated absorption
5. Optional **madhu** (honey) added cold, after full cooling, to respect the viruddha (incompatibility) doctrine — hot honey generates *Ama* (toxic metabolite)

## Pakva stages

Sharangadhara defines five grades of avaleha consistency, tested between fingers:

| Pakva | Test | Use |
|-------|------|-----|
| Mridu Paka | Thread breaks immediately | Soft avalehas, high moisture |
| Madhyama Paka | One-thread test | Classical leha / lehya |
| Kharatara Paka | Two-thread test | Chyawanprash, Haridra Khanda |
| Khara Paka | Stiff, sets on cooling | Guda-pakas |
| Atikhara Paka | Brittle on cooling | Khandapaka / crystallized |

## Why Avaleha matters

The dosage form solves four pharmacological problems classical practitioners faced:

1. **Palatability** — allows bitter herb complexes to be delivered orally with compliance
2. **Bioavailability** — the sneha (ghee/oil) matrix provides lipid-soluble absorption; the sugar-honey matrix provides rapid glucose-mediated uptake; the prakshep piperine enhances systemic absorption
3. **Shelf stability** — high sugar content (≥65% w/w total solids) + airtight storage yields 24–36 month shelf life without refrigeration
4. **Multi-constituent synergy** — allows 30–60+ herbs to be compounded in a single, stable, pleasant-tasting preparation

## API standards (Avaleha general monograph)

- Total solids: NLT 65% w/w
- Moisture: <25%
- pH: 3.5–5.0
- Microbial limits per API
- Heavy metals, pesticide residues, aflatoxins per API
- Preparation-specific markers (e.g. gallic acid NLT 0.5% for Chyawanprash)
