Kavinessa Вопрос спорный, ведь есть ингредиенты (травы), которые у магов считаются волшебными, а у магглов условно волшебными (сказки,предания) и которые если просто скушать, ничего, кроме несварения не будет. Как быть с ними? И опять же, как быть тогда с тем, что магия передается и меняет состав жидкостей организма..значит, Пожиратели были правы отчасти в теориях своих.
Насчет зелий, вот цитата из интервью Ро:
Unknown (1): Can muggles brew potions if they follow the exact instructions and they have all of the ingredients?

J.K. Rowling: Well, I'd have to say no, because there is always... there are magical component in the potion, not just the ingredients. So, at some point they will have to use a wand. I've been asked what would happen if a Muggle picked up a magic wand in my world, and the answer would probably be something accidental... possibly quite violent. Because wands, in my world, is merely a vehicle, a vessel for what lies inside the person. There is a very close relationship -- as you know -- between the wand that each wizard uses and themselves. In fact, we'll find out more about that in book 7 (crowd applauds).

For a muggle you need the ability, in other words, to make these things work properly but you're right and I think that's an interesting point. Potions seems, on the face of it, to be the most Muggle-friendly subject. But there does come a point in which you need do more than stir. Thank you, good question.
