Nature and Extraction
Essential oils are complex mixtures extracted via distillation, enfleurage, maceration, solvent extraction, and supercritical CO2 methods.
India’s Global Position
India commands a 16-17% share in global production and is the second-largest exporter by value, while the USA is a leading consumer.
Raw Material and Quality Issues
Over 90% of medicinal plants come from wild collection, affecting quality and sustainability; spice oil production in India’s horticulture sector highlights processing challenges.
Export and Research Growth
India’s essential oil exports are rising, with Andhra Pradesh contributing significantly; institutions like the National Research Centre for Medicinal and Aromatic Plants in Anand, Gujarat focus on high-yield varieties.
Pharmaceutical and Cosmetic
Essential oils have antibacterial, antifungal, and antioxidant properties used in medicines, aromatherapy, perfumes, and skincare.
