Very interesting and helpful! Thanks for sharing, Daniel!
It’s amazing how many health benefits ghost peppers have! I definitely can’t handle them but I’m getting used to spiciness in the US. Contrary to the myth, being from South America does NOT equal eating spicy food! 
I’d like to add that chili powder is also used in hot foot powder, a hoodoo blend to drive unwanted people away. And also, like you mentioned for love and fidelity spells.
