How YOUNG AS started Australia is a clean country with a rich source of natural ingredients. DNA studies prove that Aboriginal Australians are the oldest civilization, who have been using natural remedies for thousands of years. Professor Joanne Jamie, a medicinal chemist from Macquarie University, in Sydney has compiled a database on Aboriginal plants.
