Cindergut Pepper

Cindergut Peppers are extremely spicy, red chili peppers native to Pandaria. Only for those who truly love spicy food, even touching these with your bare hands is not recommended by most, although the Kunzen hozen are known to carry them on their bodies.

These peppers are also used to make cindergut powder, a hot spice that is also red. Having this blown into one's face, in the right amounts, can cause the eyes to swell shut and a runny nose.
