Looked it up because I hadn't heard of it. Wikipedia say the following:
Common names in English include Indian borage, country borage, French thyme, Indian mint, Mexican mint, Cuban oregano, broad leaf thyme, soup mint, Spanish thyme.
What? So does it taste like a mix of borage, thyme, mint and oregano?? Sure, they are all Lamiaceae (except for borage), but they have wildly different aromas!
