Ayurveda is adjective medicine. Western medicine is noun medicine. Adjectives are about the whole but nouns are about the parts. Your whole body can be hot but your whole body can't be an arm.

Ayurveda treats disease like an adjective. Influenza is a noun but a cold is an adjective. To think Ayurvedically you have to rename the disease as an adjective. We find that herbs work better when you use them to treat adjectives instead of nouns. Because herbs are whole too.
