Neem (Azadirachta indica) belongs to Meliceae family, and grows rapidly in the tropic and semi-tropic climate. The Neem Tree is an incredible plant that has been declared the Tree of the 21st century by the United Nations. In India, it is variously known as ‘Divine Tree’, ‘Life giving tree’, ‘Nature’s Drugstore’, ‘Village Pharmacy’ and ‘Panacea for all diseases’. It is one of the major components in Ayurvedic medicine, which has been practiced in India since many centuries.
Neem powder contains a unique composition of organic and beneficial compounds, so products derived from it are very popular in herbal remedies. From tea and garnishes to skin salves and herbal supplements, it is considered as one of the most important and versatile plants in the Indian culture.
Neem is therefore currently one of the world's most researched trees. It is a tree that can help solve global environmental and health concerns.
Neem Leaves are now known to contain nimbin, nimbinene desacetylnimbinase, nimbandial, nimbolide and quercentin. The constituents of the leaves have been demonstrated to exhibit immune-modulatory, anti-inflammatory, anti-hyperglycaemic, antiulcer, antimalarial, anti-fungal, anti-bacterial, anti-viral, anti-oxidant, anti-mutagenic and anti-carcinogenic properties. (Subapryia. R, 2005) Fourteen common fungi species are proven to be sensitive to Neem, including Trichophyton, Epidermophyton, Microsporum and Candida. Bacterias such as Staphylococcus aurus, Salmonella typhi, E.coli and K. pneumonia are also recognised for being suppressed by Neem. The use of Neem Leaf powder moreover facilitates Glutathione-s-transfer, thus improving the ability of the liver to detoxify itself from chemical contamination.The powder can be retailed in its original form as well as in capsules or tablets. The many bioactive phyto-chemicals present in Neem, makes it a promising nutraceutical with multiple pharmacological functions including anti-inflammatory, antioxidant, anti-viral functions.
Neem Leaves contain carotenoids that help the skin fighting damaging free radicals. Leaf extract and neem seed oil are therefore used in many skin and hair products, as well as pet shampoo. Neem leaf powder and neem seed oil are also used to prevent and treat skin issues such as acne, allergies and rashes due to their anti- bacterial and anti-inflammatory properties
Neem Leaves, known to contain nimbin, nimbinene desacetylnimbinase, nimbandial, nimbolide and quercentin, based pesticide are found to be much safer compared to the synthetic chemicals having both side effects on the humans and animals, this being mainly due to its composition in Azadirachtin. The pesticidal activity of Neem ranges from , repelling, anti-feedant, insect growth regulation, anti-ovipositional, and suppressing fecondity . Shmutter and Singh (1995) demonstrate that 413 insects are sensitive to Neem in having their reproductive growth process blocked. Neem can also be used as a bio-control agent to manage plant disease, up the 350 species of arthopods can be controlled with Neem. Finally, Neem is effective against 195 insects that have become resistant to synthetic pesticide, while it does itself not develop any resistance.
