Mentha australis – River Mint

A native mint that is used as a bush food, an insect repellent and is also said to have medicinal properties.  Mentha australis is commonly called River Mint.

The leaves can be picked and either used fresh or they can be dried. The fresh leaves are preferred as the flavour of this mint is more intense when fresh.
