Pomegranate peel powder can not be eaten regularly.
While the pomegranate skin has these effects: warm, stop dysentery, treatment of sinew and bone wind, waist and foot attempts, walking contracture pain. Take the juice of the eyes, stop tears; decoction, under the roundworm, stop diarrhea.
However, pomegranate peel has some side effects, it has a little poison, the dosage should not be too large.
So, I suggest you eat once in a while is good, and should not eat too much at a time.
