Revelation 22:2

Revelation 22:2. In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.

The fruit of this "tree of life " is for all those who have partaken of the water of life; and the tree provides medicine as well as food: " the leaves of the tree were for the healing of the nations."
