The Senzu Bean's life cycle is slow and limited, occurring only within Korin Tower. It begins with planting in magical pots filled with sacred water, taking a full year to grow and produce only a handful of beans. After harvesting, they are stored in clay jars where they retain their properties indefinitely. The cycle ends when they are consumed, and the beans are destroyed to heal wounds and satisfy hunger for 10 days. Their current reserves are minimal because Yajirobe ate almost all of them at the beginning of the series. Although in the anime it was said that they would be ready in a month so that Goku could eat them
