I don't think activating taste receptors while not having calories is harmful and haven't seen any studies to suggest otherwise. Have you? As for health benefits apparently it has antioxidant properties, but I don't know to what extent that's true. I use it because I like the taste and doesn't seem to be harmful in any way, but it also hasn't been studied as extensively.
