It is indeed. It's a very effective medicine to heal smaller wounds, and it's quite tasty as well. It's called a Dragon Tree Fruit because of the appearance of the fruit. The trees themselves grow on the northern part of the Isle of Seiren.

[And Thanatos is going to grab a piece as well. He'd been saving this in case someone got hurt and once cut into, the fruit won't last long. This one is actually fully ripened as well, so it should heal pretty fast.]
