Acknowledging the importance of plants and its Medicinal & Agricultural value, extraction of Essential Oil had been done using Steam Distillation method. In this project Steam Distillation was used to extract oil from different plant materials like eucalyptus leaves, curry leaves, hibiscus leaves, lemon leaves, marigold flowers, rose flowers, orange peels etc. Research has confirmed centuries of practical use of essential oils, and we now know that the 'fragrant pharmacy' surrounds compounds with an extremely broad range of biochemical effects.
