Tea Tree Oil

ANSWER

Captain James Cook was a British naval captain, skilled navigator experienced cartographer and successful explorer.
He is remembered for his voyages of discovery aboard his vessel Endeavor and in particular the region of Australia he named New South Wales.
Cook's sailors used the leaves of Melaleuca to brew tea despite the fact that the plant bears no relationship to Camellia Sinensis (Tea).
It was without doubt a desperate substitution however the coined name persisted and is still in use today.
Captain Cook met an untimely and violent death in Hawaii but Tea Tree Oil went on to become a popular natural bactericide and fungicide in numerous products.
This was no surprise to the aboriginal Australians as they had employed the plant for such use over hundreds of years and given their history no doubt much longer.
