There are 3 kind of logic systems 4 corners(chatuskoti), 3 corners(trikoti), 2 corners( binary logic). Entire western civilization is build top of binary logic. Only one god, america has friends(5 eyes) and enemies but no nutral parties(there are occasional cat paws ).
From western binary logic they can't even explain zero(mathematically). One reason is science is not global thing it's creation of given culture(In current case western culture). Because western main philosophy is binary one and as per there binary logic they thing there are only one science. And since west control the world for half millennia and still control the world they teach us there are only one global/universal science. example if you change Euclid's main assumptions you get entirely different geometry. In some comments says that ayurved is joke or useless fact is I know(and probably OP know's) it can cure series illnesses like cansces/diabetic and etc.
Trying to understand ayurvedic methods using modern western apothecary teaching is absolutely useless.
