Six Paths Yang Power

Overview
Passed down to Naruto Uzumaki, from the Sage of the Six Paths, Hagoromo Ōtsutsuki, the Six Paths Yang Seal is a sealing tattoo that is, and when combined with Sage Mode, capable of not only increasing the bearer's overall physical parameters to the point of surpassing even the jinchūriki of the Ten-Tails and allows him to revitalise the life-forces of another individual, but also serves as one half of a powerful sealing technique that is capable of sealing bothe the Ten-Tails and Kaguya Ōtsutsuki.

Healing
By utilising the Yang Release withing the seal, he can heal others from an otherwise fatal and untreatable condition; such as halting the effects of the Eighth Gate on Might Guy, restoring Kakashi Hatake's missing eye, and resuscitating a dying Obito Uchiha. This ability, however, does have its limits as Naruto was unable to heal the effects of Kaguya Ōtsutsuki's All-Killing Ash Bones, albeit being capable of slowing down the process enough for the latter to give his final wishes.
