White pepper, like black pepper, is made from the berries of the pepper plant, also known as the Piper nigrum. Unlike black pepper, however, white pepper comes from berries that are picked at full ripeness. These berries are then soaked in water to ferment.
White pepper is a good source of flavonoids, vitamin A, and vitamin C. These aid in lowering high blood pressure. Thus, white pepper may help manage blood pressure.
