Neem has rightly been called sarvaroghari . Since time immemorial, Indians have learnt and made use of neem in a variety of ways both for personal and community health by way of environmental amelioration. Despite all the vicissitudes India has gone through over the centuries, neem has managed to remain a friend, philosopher and guide to an average Indian. It is time this heritage is appreciated and in area of promotional and preventive health care, our indigenous knowledge and resources are made use of on an increasing scale as low-cost, effective ingredient for the realization of the lofty goal of ‘Health for all'.

As Naveen Patnaik (1993, p. 40) says, “Possessed of many and great virtues, this native Indian tree has been identified on the five-thousand-year-old seals excavated from the Indus Valley Civilization”. How the tradition lives on has also been graphically brought out, “Today the margosa is valued more highly for its capacity to exercise the demon of disease than the spirit of the dead, and an image of the folk goddess Sitala can often be seen suspended from a margosa branch where she guards against small pox, once the great killer of the Indian country side. Renowned for its antiseptic and disinfection properties, the tree is thought to be particularly protective of women and children. Delivery chambers are fumigated with its burning bark (Margosa seed oil has been chemically tested as an external contraceptive, used by women as a spermicide). Dried margosa leaves are burned as mosquito repellent. Fresh leaves, notorious for their bitterness, are cooked and eaten to gain immunity from malaria.

Neem's antiseptic properties are widely recognized now. “Neem preparations are reportedly efficacious against a variety of skin diseases, septic sores, and infected burns. The leaves, applied in the form of poultices or decoctions, are also recommended for boils, ulcers, and eczema. The oil is used for skin diseases such as scrofula, indolent ulcers and ringworm.

Cures for many diseases have been reported but these need to be confirmed independently by trials under controlled conditions. Laboratory tests have shown that neem is effective against certain fungi that infect the human body. Some important fungi against which neem preparations have been found to be effective are: athlete's foot fungus that infects hair, skin and nails; a ringworm that invades both skin and nails of the feet; a fungus of the intestinal tract; a fungus that causes infections of the bronchi, lungs, and mucous membranes and a fungus that is part of the normal mucous flora that can get out of control leading to lesions in mouth (thrush), vagina, skin, hands and lungs.

Neem has been used traditionally in India to treat several viral diseases. Even many medical practitioners believe that smallpox, chicken pox and warts can be treated with a paste of neem leaves – usually rubbed directly on the infected skin. Experiments with smallpox, chicken pox, and fowl pox show that although neem does not cure these diseases, but it is effective for purposes of prevention. ‘Crude neem extracts absorb the viruses, effectively preventing them from entering unaffected cells.” Recent tests, although unconfirmed, have shown that neem is effective against herpes virus and the viral DNA polymerase of hepatitis B virus. Should these findings be confirmed, neem could be used to cure these dreadful diseases.

Its effectiveness is enhanced on account of its easy and plentiful availability and low cost along with the advantage – a big and critical advantage – of crating income and employment for the poor. Neem is effective against dermatological insects such as maggots and head lice. It is a common practice to apply neem all over the hair to kill head lice
