The lovely purple flowering tree, jacaranda mimosifolia, is native to Brazil and the West Indies, but is widely grown in Australia.
Nobel Laureate Alice Munro refers to it in a slightly comic story about an abandoned Ontario woman who follows her man to Australia, to a place she thinks of as The Jack Randa Hotel.
The protagonist in the story is scattered, rushing off before she can decide what she really wants. Perhaps this character should have taken this essence to help her become more clear-minded, decisive and centred.
The Jacaranda essence supports the Brow Chakra and is associated with the Mental and Astral planes.
