I've spoken with a number of herbalists over the years who held this opinion, but it was really an Ayurvedic doctor who brought it home for me, as she explained that, in that part of the world, those three oils are commonly used together, as they work synergistically when used together, often in combination with ginger and black pepper.

It resonated with me the first time I heard it, and has ever since, so I'm inclined to believe that it is at the very least quite likely.
