Cannabidiol, or CBD, has gained significant popularity, particularly as a method for relieving pain and anxiety, and it’s starting to pop up in patch form as well.

Both guarana and yerba mate contain caffeine. It’s a stimulant, so it can boost your energy, but patch manufacturers also claim both herbs can help you burn more calories and melt more fat.
