Azadirachta indica, commonly referred to as neem, is a highly versatile and diverse tree found in tropical regions, particularly India, with potential medicinal properties. Neem offers a range of valuable non-wood products including flowers, leaves, fruits, bark, gum, oil, seeds, and neem cake. This abundance of resources sets it apart as an exceptionally beneficial tree compared to others.
In Sanskrit, neem is known as 'arista,' signifying perfection and perishability, while 'Nimba' originates from the term 'nimbati swasthyamdadati,' meaning 'to give good health.' Even the Persians named it 'Azad-Darakth-E-Hind,' translating to 'Free Tree of India.' Neem's significance extends to environmental protection, pest control, and medicine, as it demonstrates the potential for natural pesticides, insecticides, agrochemicals, and health-related applications.
Nutritional Value of Neem
Investigations into leaf meals derived from certain tropical legumes have arisen from the necessity to discover substitute food sources for humans and fodder for livestock. An analysis of neem leaf meal indicated a substantial crude protein content of 18.10%, accompanied by a relatively elevated crude fibre level ranging from 15% to 56%. Despite a notably high gross energy content of 4.16 kcal/g, the metabolizable energy is limited. This suggests the potential utility of neem leaf meal as a protein, vitamin, mineral, and carotenoid source for non-ruminant animals as well.
