Whatever truths are contained in Ayurvedic texts are accidental unless they were arrived at by some sort of experimentation, and they're mixed in with a lot of nonsense which "Western" science is attempting to sift through. Along with proving the potency of some Ayurvedic treatments, science is also DISproving that of many others, which means that it's not "catching up" with Ayurvedic so much as catching it, shining a bright light on it, and asking it much tougher questions than anybody thought to ask before.
