- Natural distribution: Found naturally in the tropical forests of the Western and Eastern Ghats, Odisha, Andhra Pradesh, Maharashtra, and Tamil Nadu.
- Climate and soil: Thrives in tropical humid climates receiving over 1,000 mm annual rainfall, preferring well-drained sandy loam and lateritic soils.

- Fruiting cycle: Trees produce smooth orange-yellow globular fruits containing 1 to 5 flat, silky, disc-shaped seeds that ripen during winter.
Medicinal value and mandatory Ayurvedic Shodhana
In traditional Indian medicine systems, Kuchla is designated as an Upavisha (sub-toxic substance). Unprocessed raw seeds are extremely poisonous and must never be consumed. Under AYUSH pharmacopoeial standards, the seeds undergo rigorous Shodhana purification—traditionally boiled or soaked in cow milk, gomutra, or castor oil—which lowers acute toxicity while preserving therapeutic neuromuscular and tonic properties.
Harvesting, regulatory compliance and marketing
- Collect fallen ripe fruits, separate seeds from pulp, wash thoroughly in clean water, and dry in the shade on raised tarpaulins.
- Comply with local forest department transit permits and sustainable collection norms established by State Medicinal Plants Boards.
- Market produce directly to licensed Ayurvedic, Unani, or pharmaceutical manufacturers certified under Good Manufacturing Practices (GMP).
