Charms are also called talismans, or amulets.
They’re objects but also words; spells, chants and incantations.
Rosaries and holy relics are encouraged and blessed.
Other objects are thought of as superstitious.
In the 17th century Scotland a charm could be reason enough to condemn someone to be burned.
In South America shamans must have a large knowledge of many charms to battle illness, overcome evil, and destroy enemies.
