The Empire Saga
Little green beans with amazing healing properties.
When eaten a Senzu bean recovers full hit-points for the person eating the bean and half of their full power level. Example – Jot has only 35 hp out of 200 and 10k power out of 50k. He eats a Senzu bean and is immediately back to full hp (200) and gains 25k power, putting him at 35k power available.
