Plant
Neem
Azadirachta indica
Also known as: Azadirachta indica, Indian lilac, margosa
A fast-growing evergreen tree native to the Indian subcontinent — one of the most extensively used multipurpose plants in any traditional pharmacopoeia. Every part of the tree (leaves, bark, seeds, oil, twigs, roots) is used medicinally or practically in Ayurvedic and Unani traditions. The seed oil contains azadirachtin, one of the most-studied natural insecticides — globally available as the active ingredient in many organic-pest-control products. Called *Sarva roga nivarini* ('curer of all ailments') in Sanskrit and 'the village pharmacy' in colloquial Indian usage.
Scientific
Azadirachta indica (family Meliaceae) is fast-growing and drought-tolerant — qualities that have made it one of the most-planted reforestation and village-shade species across South Asia and Africa.
The seed oil contains azadirachtin and several related limonoid compounds with documented insect-repellent, insect-antifeedant, and growth-disrupting properties. Azadirachtin is now the active ingredient in many commercial organic insecticides, including Neem Oil, NeemAzal, and dozens of horticultural products.
Cultural and medicinal
Neem is one of the most extensively used plants in Indian traditional medicine — every part has a documented Ayurvedic or Unani indication:
- Leaves — eaten or applied for skin conditions, fevers, parasites
- Bark — decoctions for fever, malaria, ulcers
- Twigs — chewed as natural toothbrushes (the miswak / datun tradition)
- Oil — applied topically for skin and hair conditions; used in soaps and cosmetics
- Seeds — pressed for oil, ground into pest-control pastes for grain storage
- Roots — decoctions in traditional pharmacology
The Sanskrit name Sarva roga nivarini (“curer of all ailments”) reflects the tree’s status. Many Indian villages traditionally plant neem at the entrance to homes for medicinal access, pest control, and cooling shade.
The species is also a key plant in the global organic-agriculture toolkit — neem-based pesticides are accepted under most organic certifications because the active compounds break down quickly in the environment, don’t accumulate in tissues [[daoism|the way]] synthetic pesticides do, and are selectively toxic to insect pests with low mammalian toxicity.
Modern biopiracy controversy
The 1995 US patent granted on a neem-oil fungicide preparation by W.R. Grace & Co. became a landmark case in biopiracy debate. India and the international NGO RAFI challenged the patent on the grounds that the use was already documented in centuries-old Ayurvedic texts and therefore not novel; after a 10-year legal battle the European Patent Office revoked the patent in 2005, partially establishing the principle that traditional knowledge constitutes prior art.
