Slow Havamal: 147

In verse 147, Odin says he knows a second spell that me need to know in order to heal others.

In this short verse, we learn that the next purpose for which the Norse might have used magic is in healing. Unlike the previous spell, this one does seem to be accessible to men, and in fact it’s necessary according to Odin. We don’t learn anything about what it is or how to acquire it, but presumably that would either be obvious—as in, there’s a woman in every village who can teach it to you—or you would simply ask Odin, himself.
