Long, long time after Jesus, the people were being burnt to death for "witch" because they know how to heal sick people with herbs. They have no idea what "miracle" is but evil or witch. I know those history was in England. I beleive that it´s also the same with other countries as well, not just Islamic.
No, it has nothing to do with herbs. There were victims from witches, like the movie what it called and also the missing reporter ( few years ago) and was a true story and even reporting missing people and spells and etc. (before America been named)
