This is a great question! The simple answer is, “No!”
Ayurveda, of course, comes out of the civilization that communicated in Sanskrit, and even though Sanskrit isn’t commonly spoken, it is still a viable language. All of the ancient texts about Ayurveda—and its related Vedic sciences—are written in Sanskrit, so students of Ayurveda are steeped in it, and practitioners find its terminology useful. It is sometimes helpful to use Sanskrit because it is such a poetic, lyrical, and musical language.
You, however, are not expected to know these words and terms. If we use a Sanskrit term with you, there will be a reason why we do so, and we’ll provide the English equivalent.
