Neem Tree

If you are visiting India and ask for the village pharmacy then you're likely to be pointed towards this tree. The discovery of its complex chemical pesticide qualities make it resistant to more than two hundred different types of insect, as well as various mites, nematodes, fungi, bacteria and viruses . Although lethal to bugs it does not have an adverse effect upon humans, animals or birds.

Weed Warning: This tree will not succeed in temperate zones and is far from a weed in most subtropical areas as it has a reputation for turning up its toes in through the winter in the subtropics, however in tropical climates it is much hardier and has been recorded to spread through large areas in Northern Queensland.
