Medicinal plant and tree farming involves cultivating botanicals traditionally used in Ayurveda, Unani, Homoeopathy, and modern herbal industries. With rising demand in wellness, pharmaceuticals, and natural health sectors alongside government support, it presents an attractive opportunity for sustainable, high-value agriculture.
Benefits of Cultivating Medicinal Plants
- High-value demand from AYUSH products, herbal extracts, essential oils, teas, and nutraceuticals.
- Adaptable to marginal lands, offering productive use of semi-arid or low-fertility areas.
- Environmental advantages: soil regeneration, biodiversity enhancement, reduced chemical input.
- Government incentives via NAM and NMPB in the form of subsidies for cultivation, nursery, processing, and marketing are also available in India for whoever wants to cultivate on a larger scale.
Species-by-Species Detailed Cultivation Guide

Government Schemes & Support Overview
- NAM for Medicinal Plants Component:
- Subsidies of 30%, 50%, or 75% depending on species and region.
- Fully funded in North-Eastern and Hill states.
- Coverage: Cultivation, nurseries, QPM, processing units, clusters.
- NMPB Central Sector Scheme (2021–26):
- Focus on conservation, value addition, warehousing, and certification.
How to Access:
- Visit your State Medicinal Plants Board or AYUSH department portal.

- Consider forming or joining farmer clusters/FPOs for better access to shared infrastructure and collective marketing.
Smart Agronomy Tips
- Soil pH & type: Most MAPs thrive in sandy loam; ensure proper drainage (especially for Aloe, Giloy).
- Use certified planting material: Disease-free nursery transplants or QPM; particularly crucial for turmeric, tulsi, moringa, and ashwagandha.
- Water management: Align irrigation with crop stage—low-water species (aloe, ashwagandha) require minimal irrigation; high-water ones (mentha, amla) need timely moisture.
- Pests & disease: Use botanical solutions (neem-based), especially for crops like peppermint prone to fungal issues.
- Post-harvest: Shade-dry herbs promptly; cure rhizomes (turmeric); clean roots and leaves; maintain moisture standards.
