Great questions =) If I may point you to http://www.bragg.com who makes the ACV I've used. It's raw, unfiltered and unpasteurized. It's good for everything from itchy heads to itchy skin, from weight loss to weight gain, from nose bleeds to restless leg.
The taste is a bit much for me, so I mix with a little honey as they suggest - a cocktail. But you can simply mix it with water to dilute it's taste strength. Good stuff!
