Neem
Neem trees are medium to large sized, drought resistant, multipurpose trees, that can be up to 30 m tall. All parts of the plant produce azadirachtin, a powerful antibiotic and antimicrobial. Seeds and leaves often have the highest concentrations and may be used to make insecticides and fungicides. Neem is also used for fuelwood, makes excellent charcoal, and is a source of durable timber.
