translate "For the healing of all mankind" to Latin?

Answer 1

Hi, this is the best I can do:

"(pro) sanatione humanitatis universae"

or

"(pro) sanatione humanitatis totae"


...or else, less literally:
"(pro) salute hominum omnum" = "for the health of all people"


The word "pro" (for) is in parentheses because it is not necessary since the ablative case of the word "healing" alone can also indicate the "for". Leaving the "pro" out makes it sound more elegant, but perhaps less clear/less explicit.

Answer 2

"ad sanitatem gentium" (Revelation 22:2)
