About Eucalyptus
Eucalyptus was brought to the Nilgiri Hills from Australia in the 1840s, and "nilgiri oil" is now the common name for eucalyptus oil in India. It grows fast and is widely planted for paper pulp and poles. It is also controversial: dense plantations use a lot of groundwater and suppress undergrowth, so they are discouraged near water-scarce farmland.
Botanically known as Eucalyptus globulus, it belongs to the Myrtaceae family. It is native to Australia and grows best in a tropical/sub-tropical climate. The parts most often used are the wood, leaves and oil.
