Botany: Neem is a fast-growing tree that can reach a height of 15–20 metres, rarely to 35–40 metres. It is evergreen, but in severe drought it may shed most or nearly all of its leaves. The branches are wide spread. The fairly dense crown is roundish or oval and may reach a diameter of 15–20 metres in old, free-standing specimens.

History and/or folklore: The medicinal and antimicrobial activity of plant extract has been known for generations. The earliest use of a plant being used as human medication is found on an Egyptian papyrus dated about 1550 BC (the Ebers Papyrus-ACD). Almost every part of the neem tree is used in traditional medicine in India, Sri Lanka, Burma, Indochina, Java and Thailand. The stem, root bark, and young fruits are used to treat malaria and cutaneous diseases. The tender leaves have been used in the treatment of worm infections, ulcers, cardiovascular diseases and for their pesticide and insect-repellent activity. Neem oil has been used in traditional Indian medicine for thousands of years, practically as a panacea for all ailments. It is one of Indian’s most reverential treatments for problem skin.

Neem bark and leaves
Traditional use: Neem is commonly used for toothbrushes for cleaning the teeth, mouth and hands. Neem is one of the trees that are used in India for toothbrushes. Chewing neem sticks is still common in India, although most modern Indian use neem toothpaste instead. In the toothpaste neem leaf powders and extracts are mainly used. The neem leaf is not the most effective neem product for dental care purposes, but manufacturers do not want to use the more effective bark in a toothpaste, because that would make it brown.
