If you don't understand the difference, how can you question it? There is no active ingredient in homeopathic remedies. They belive what makes you ill makes you better so they say put a drop arsenic and say they dilute it to 1 in a million or more.
So say you have a headache a homeopath would give you, say, a drop of diluted asprin that drop of asprin would be dropped ( in proportion) in a swimming pool, but much more, and you would get a bottle from the pool to cure your headache.
