Interesting stereotype you've got there. I have a huge Amish community near me. Not only do they adhere to strange folk remedies, but they sell various tonics based on same and have a couple faith healers who accept donations for healing any English wanting help. And these are Old Order Amish, not the new order who carry cellphones, drive diesel tractors, and the like.
The local Amish also buy and drink coffee, as well as whiskey, although the latter is for when they're sick. And they have their own Amish dentist - I've never heard of an Amish seeing an English doctor or dentist, but I know of an old coot who insists on only seeing Amish healers and the dentist. They hire local hippie midwives for birthings. Could be the community near you is different than the community near me.
And then there's this guy, a local. If you look at the pictures, you will notice despite being Old Order, he had no qualms about running illegal electricity to his "project barn":
The 33-year old Amish man who is now facing drug and weapons charges was not born into the Amish community. Detectives say he joined several years ago.

One of the local country grocer's still has a "Free Appleby" sticker outside. The local rumor is that the Amish are disavowing him because the operation was much bigger than what the law found.
