This beauty was growing at the Aripeka entrance of the Weeki Wachee Preserve. It looks similar to Brazilian Pepper, so I wasn't about to touch it. Which is a good thing, because as I read about it sounds like there's not too much use for this plant medicinally. That being said, the berries supposedly contain caffeine and theobromine, a caffeine metabolite that has some unpleasant effects. It is also the reason why chocolate is poisonous to dogs. It sounds like it would be difficult to isolate that perfect amount of berry that would grant a caffeine boost without also granting theobromine poisoning to humans, which causes seizures and death.
That being said, hollies are beautiful in the winter.
