(don't) Drink and be damned

Having posted the story about the New York Christians who may have contracted Hepatitis A from a fellow communion drinker I came across another story today, this one is about an Indian shaman who prepared a herbal brew for local Women to drink in order that they prove themselves not to be witches, unfortunately for them it was poison and several are now seriously ill.

I was struck by how similar these stories are, we might almost derive a consistent narrative around what happens when reality intersects with superstition?
