Why are there lots of “tea tree” oils and do they all have medicinal properties?
Fact: There are lots of plants known as “tea trees” including plants in the Melaleuca and Leptospermum genera. However, tea tree oil (TTO) can only be produced from a very small number of plants, mainly Melaleuca alternifolia. These other oils may have medicinal properties such as antimicrobial activity but few have been scientifically investigated as much as TTO.
