Habitat: Azadirachta indica is native to India and the Indian subcontinent including Nepal, Pakistan, Bangladesh and Sri Lanka. It is typically grown in tropical and semi-tropical regions. Neem trees now also grow in islands located in the southern part of Iran. Its fruits and seeds are the source of neem oil.
Description:
Neem is a fast-growing tree that can reach a height of 15–20 metres (49–66 ft), and rarely 35–40 metres (115–131 ft). It is evergreen, but in severe drought it may shed most or nearly all of its leaves. The branches are wide and spreading. The fairly dense crown is roundish and may reach a diameter of 15–20 metres (49–66 ft) in old, free-standing specimens. The neem tree is very similar in appearance to its relative, the Chinaberry (Melia azedarach).
The opposite, pinnate leaves are 20–40 centimetres (7.9–15.7 in) long, with 20 to 31 medium to dark green leaflets about 3–8 centimetres (1.2–3.1 in) long. The terminal leaflet is often missing. The petioles are short.
The (white and fragrant) flowers are arranged in more-or-less drooping axillary panicles which are up to 25 centimetres (9.8 in) long. The inflorescences, which branch up to the third degree, bear from 150 to 250 flowers. An individual flower is 5–6 millimetres (0.20–0.24 in) long and 8–11 millimetres (0.31–0.43 in) wide. Protandrous, bisexual flowers and male flowers exist on the same individual tree.
The fruit is a smooth (glabrous), olive-like drupe which varies in shape from elongate oval to nearly roundish, and when ripe is 1.4–2.8 centimetres (0.55–1.10 in) by 1.0–1.5 centimetres (0.39–0.59 in). The fruit skin (exocarp) is thin and the bitter-sweet pulp (mesocarp) is yellowish-white and very fibrous. The mesocarp is 0.3–0.5 centimetres (0.12–0.20 in) thick. The white, hard inner shell (endocarp) of the fruit encloses one, rarely two or three, elongated seeds (kernels) having a brown seed coat.

Commercial plantations of the trees are not considered profitable. Around 50,000 neem trees have been planted near Mecca to provide shelter for the pilgrims.
Warning: The neem tree is very much lookalike to the Chinaberry, whose fruits (and everything else) are extremely poisonous.
Medicinal and other uses:
Neem Leaf is said to be India’s best-kept secret, and for thousands of years this “Pride of India”
has treated more than one hundred health problems! It is said to be one of the most important detoxicants in Ayurvedic medicine and is also believed to be a potent antiviral, antifungal, antibacterial and parasiticide that combats infections of all kinds. In addition, Neem is used to facilitate digestion, support heart health, improve the urinary tract and treat fevers and pain. Important, new research claims that Neem will help diabetics and combat invasive disease.
Neem Leaf is a bitter tonic herb that nourishes and strengthens the digestive tract and is excellent for digestive disorders. Because it is believed to work wonders for the gastrointestinal tract (the passage along which food passes for digestion, including esophagus, stomach, duodenum, liver, pancreas, gallbladder, small and large intestines), Neem is often taken to correct problems of the stomach and bowels and is effective in easing nausea, indigestion, gastritis, intestinal distress, hyperacidity, and peptic and duodenal ulcers. It also appears to reduce gastric secretions and aids in eliminating toxins and harmful bacteria from the system, thereby reducing stomach discomfort.
In the treatment of constipation, Neem Leaf is thought to be an effective purgative, especially in larger doses, but because it is also a soothing demulcent, it is not a harsh laxative, and its use is thought to regulate bowel function. It has also been used as an anthelmintic, which destroys and expels intestinal worms, perhaps because of its effective laxative and parasiticidal properties.
Neem Leaf is thought to support heart health in several ways. Recent studies have shown that the leaf extract, nimbidin, significantly lowers serum cholesterol levels, which helps to reduce blood clots. Nimbidin also causes blood vessels to dilate and may be responsible for lowering blood pressure and improving blood circulation. These actions are thought to reduce the risk for arteriosclerosis, stroke and heart attack. Moreover, it is also thought to slow rapid heartbeat and inhibit irregularities of the rhythms of the heart (arrhythmia).
Neem Leaf is said to improve many urinary tract disorders, especially burning urination. The leaf extract, sodium nimbidinate, acts as a diuretic, promoting the flow of urine, and this action helps to relieve phosphaturia (excess phosphates in the urine) and albuminuria (escess albumin in the urine), which can be caused by chronic congestion of the kidneys. The increased urine helps to flush the kidneys and further cleanse toxins from the system.
The tannin in Neem Leaf acts as an astringent, and as such, it has been used to remedy diarrhea and dysentery.
Neem Leaf is said to be one of the finest detoxicants available that clears pollutants from the body. The herb’s antiseptic qualities are said to cleanse the blood of harmful bacteria that cause infections. Moreover, cleaner blood is invaluable for improving skin conditions, and Neem Leaf has been famous for its beneficial effects in cases of skin diseases and problems, including eczema, psoriasis, septic sores, infected burns, boils, acne and scrofula.
Supporting Neem’s traditional role as an antibacterial (twig) toothbrush, modern studies confirm its important role in total oral hygiene. Neem’s antimicrobial and antiseptic properties are effective in reducing plaque, caries, gingival scores and pathogenic (disease causing) bacteria in the mouth. A mouthwash prepared from Neem extract was found to inhibit the growth of Streptococcus mutans,
an oral pathogen (bacteria) responsible for dental caries and was effective in reversing mouth ulcers (incipient carious lesions).
Recent research is being conducted into the use of Neem Leaf for diabetes. A number of insulin-dependent diabetics were able to reduce their insulin considerably when treated with Neem Leaf extract and Neem oil. The general impression is that Neem may enhance insulin receptor sensitivity and may work well on Type II diabetics.
Neem Leaf is a virtual living pharmacy and is a powerful antibacterial and antifungal. Its quercetin content (a polyphenolic flavonoid) helps to combat infections and certain fungi. Neem is believed to destroy the fourteen most common fungi that infect the human body, such as athlete’s foot, nail fungus, intestinal tract fungi and a fungus that is part of the normal mucous flora that may get out of control and lead to lesions in the mouth, vagina, skin, hands and lungs.
As an antiviral, Neem Leaf has been used to combat smallpox, chicken pox, and recent tests have shown that it may be effective against herpes virus and the viral DNA polymerase of hepatitis B virus.
Neem has been used in Ayurvedic medicine to treat malarial fevers, and recent experiments have shown that one of the Neem’s components, gedunin, is as effective as quinine against malaria. It is also used to control trypanosomiasis (African sleeping sickness or Chagas’ disease), caused by a parasite that lives inside nerve and muscle cells. Neem is also considered effective in reducing fever, relieving pain and reducing inflammation.
Neem Leaf is said to be an expectorant that loosens and expels phlegm and congestion from the respiratory system and has been used to relieve dry cough, nasal congestion, bronchitis, laryngitis, pharyngitis, tuberculosis, pleurisy and other respiratory disorders.
Neem has been used effectively as a contraceptive since the first century B.C., when an eminent Ayurvedic physician wrote of its use for this purpose. It is a highly potent antibacterial, spermicidal, parasiticide, antifungal and antiviral, and in cases of sexual contact, current studies claim that it may help to prevent AIDS, gonorrhea, trichomonas, chlamydia and other sexually transmitted conditions. Whether ingested or used topically in the vagina, the leaves and oil have been effective in killing human spermatozoa. Many women in Madagascar chew Neem leaves every day, which is believed to prevent pregnancies, and in cases of unwanted pregnancies, it is thought to be capable of inducing a miscarriage (it is a uterine stimulant that has also been used to stimulate suppressed menstruation). Neem Leaves have been used as a vaginal douche to heal wounds caused during delivery and disinfect the vaginal passage.
When used externally, Neem Leaf is used as an eyewash for the treatment of night blindness, in shampoos for hair loss and premature graying. Used topically, its antiseptic, insecticidal and antiviral properties are believed efficacious against septic sores, warts, infected burns, ringworm, lice, boils, ulcers, indolent ulcers, glandular swellings, wounds, smallpox, syphilitic sores and eczema. Its anti-inflammatory qualities will also relieve painful joints and muscles.

Construction: The juice of this plant is a potent ingredent for a mixture of wall plaster, according to the Samar??ga?a S?tradh?ra, which is a Sanskrit treatise dealing with ?ilpa??stra (Hindu science of art and construction).
Neem oil is used for preparing cosmetics such as soap, shampoo, balms and creams as well as toothpaste.
Toothbrush: Traditionally, slender neem twigs (called datun) are first chewed as a toothbrush and then split as a tongue cleaner. This practice has been in use in India, Africa, and the Middle East for centuries. Many of India’s 80% rural population still start their day with the chewing stick, while in urban areas neem toothpaste is preferred. Neem twigs are still collected and sold in markets for this use, and in rural India one often sees youngsters in the streets chewing on neem twigs. It has been found to be as effective as a toothbrush in reducing plaque and gingival inflammation.
Tree: Besides its use in traditional Indian medicine, the neem tree is of great importance for its anti-desertification properties and possibly as a good carbon dioxide sink.
Neem gum is used as a bulking agent and for the preparation of special purpose foods.
Neem blossoms are used in Andhra Pradesh, Tamil Nadu and Karnataka to prepare Ugadi pachhadi. A mixture of neem flowers and jaggery (or unrefined brown sugar) is prepared and offered to friends and relatives, symbolic of sweet and bitter events in the upcoming new year, Ugadi. “Bevina hoovina gojju” (a type of curry prepared with neem blossoms) is common in Karnataka throughout the year. Dried blossoms are used when fresh blossoms are not available. In Tamil Nadu, a rasam (veppam poo rasam) made with neem blossoms is a culinary specialty.
Cosmetics : Neem is perceived in India as a beauty aid. Powdered leaves are a major component of at least one widely used facial cream. Purified neem oil is also used in nail polish and other cosmetics.
Bird repellent: Neem leaf boiled in water can be used as a very cost-effective bird repellent, especially for sparrows.
Lubricant : Neem oil is non-drying and it resists degradation better than most vegetable oils. In rural India, it is commonly used to grease cart wheels.
Fertilizer : Neem has demonstrated considerable potential as a fertilizer. Neem cake is widely used to fertilize cash crops, particularly sugarcane and vegetables.
Plant protectant : Ploughed into the soil, it protects plant roots from nematodes and white ants, probably as it contains the residual limonoids.
In Karnataka, people grow the tree mainly for its green leaves and twigs, which they puddle into flooded rice fields before the rice seedlings are transplanted.
Resin : An exudate can be tapped from the trunk by wounding the bark. This high protein material is not a substitute for polysaccharide gum, such as gum arabic. It may, however, have a potential as a food additive, and it is widely used in South Asia as “Neem glue”.
Bark : Neem bark contains 14% tannin, an amount similar to that in conventional tannin-yielding trees (such as Acacia decurrens). Moreover, it yields a strong, coarse fibre commonly woven into ropes in the villages of India.
Honey : In parts of Asia neem honey commands premium prices, and people promote apiculture by planting neem trees.
Soap : 80% of India’s supply of neem oil is now used by neem oil soap manufacturers. Although much of it goes to small-scale speciality soaps, often using cold-pressed oil, large-scale producers also use it, mainly because it is cheap. Additionally it is antibacterial and antifungal, soothing and moisturising. It can be made with up to 40% neem oil. Generally, the crude oil is used to produce coarse laundry soaps.
Against pox viruses : In India, people who are affected with pox viruses are generally made to lie in bed made of neem leaves and branches. This prevents the spreading of pox virus to others and has been in practice since early centuries.
Known Hazards: Neem oil can cause some forms of toxic encephalopathy and ophthalmopathy if consumed in large quantities
