Tab

It is leafy, with upright branches and evergreen, it can reach up to seven metres and has small lanceolate leaves. Its fruits are small capsules containing elongated seeds and its flowers have five petals and are very fragrant.

Why call a tree that has nothing to do with tea "tea tree"? It was discovered in Australia by the naturalists accompanying Cook on his second voyage in the Endeavour (1772-1775), when it was given this misleading name. Did its leaves actually replace the tea that the great navigator's crew lacked so direly? Another version says that an Australian lake where ill people who bathed in it were healed was surrounded by beneficial trees whose leaves fell into the water and infused under the sun. Whatever the truth, the healing virtues used by the Aboriginals were so obvious that the soldiers from the Second World War Australian expeditionary force included tea tree in their field pharmacy.
