Senzu Bean

Senzu Beans are mystical beans with immense rejuvenation properties.

Other World Series
Senzu Beans are grown by Master Kai in Other World. When eaten, the consumer's energy and physical health are restored to their fullest; the effects are typically almost instantaneous for the recipient, making these beans a great asset both in and out of battle. Their texture is said to be a cross between an uncooked (or under ripe) bean and a celery stalk, and Master Kai states that Senzu Beans taste like fish. One bean can keep a person full for ten days.
