I was reading a book about the Zulu Wars against the British. The Zulus would wear JuJu GrisGris bags that would protect them from British bullets. I did some research on JuJu GrisGris bags and found out it can protect you from disease and evil as well as bullets. I even found out that you can buy JuJu GrisGris bags on Etsey and also from this vendor:
