Eucalyptus leaf comes from an evergreen species of tree in the myrtle family that grows in Australia that is also known as blue gum or Australian fever tree.
A favorite snack for koala bears, the glossy leaves are widely used in floral crafts.
Dried eucalyptus leaf is used to make infused oils, salves or chest rubs and other topical preparations. The dried leaf is also used in facial steam baths and herb pillows.
