Neem-Azadirachta indica

Chemical composition

The neem tree has numerous medicinal properties by virtue of its chemical compounds. Seeds of the neem tree contain the highest concentration of azadirachtin, a chemical [an effective natural insectide]. Neem also has salannin, gedunin, azadirone, nimbin, nimbidine, nimbicidine, nimbinol, etc., which are important liminoids [steroid-like substances].

General uses

Neem has been the most traditionally used plant in India, Pakistan and Africa. It’s used to protect grains and cereals from pests.

Fresh neem leaves are mixed with grains and cereals before storage. A paste of fresh neem leaves is also rubbed against the wall of large mud bins, or gunny bags, in which the grains and cereals are stored. Sometimes, a thick layer of dry neem leaves are spread over grains. Neem oil, extracted from seeds, acts as an effective and safe bio-pesticide. Jute bags treated with neem oil, or extracts of neem, are also used to store food grains. Neem oil is a very cheap and effective household pesticide. It protects grains and legumes. Neem is used to protect stored roots and tubers from potato moth too.

Azadirachtin is available in high concentration in neem seeds. It is used as a “botanical pesticide,” and is environmentally-friendly. It prevents insects from feeding on plants and regulates the growth of insects.

Neem extracts, however, do not harm insects like bees and butterflies, which help in pollination.
