The Tree of Renewal is a magical tree that appeared in the Aladdin episode "Eye of the Beholder".
After Jasmine was turned into a Nagi by Mirage's cursed lotion, Aladdin and company set out to find the tree. Of course, Iago knew that reaching the tree was impossible, but Aladdin was willing to do whatever it took to get there.
Following the markers (mystical stone tablets) set up by the Ancient Nomads, the group eventually reached the Tree. But Mirage made it shrivel up and disappear, leaving Jasmine saddened and hopeless. When Mirage revealed herself to the group, she shredded up Genie when he tried to take her out. Aladdin decided that if he and Jasmine couldn't be together as humans, they'd instead live together as snake creatures. Mirage threw a fit, outraged that love had proven to be stronger than she'd anticipated. Much to Mirage's dismay, Fasir used his mystic powers to restore the Tree of Renewal. Jasmine and Aladdin each took a bite from one of its fruits, and the two were restored to normal.
