No, he did not. Aragorn has an uncanny skill as a healer because he was destined to, and thats derived from his backstory being effectively raised by Elves.
People don't often understand or even realize that much of what we see as "magical" in LOTR is just uncanny skill. Things like Lembas Bread or Elvish Rope may seem wildly magical relative to us, but thats because we're no better than Hobbits. Elves know more about how their world works and this reflects in how they can exploit their long lives to develop fantastical skills with what are otherwise mundane practices.
Hence travel bread that can satiate a grown man in a single bite, and rope that can untie itself from any knot as the users command.
And anyway, the uncanny is ultimately where something like the Ranger as class ought to lie. Mundane and fantastical, simultaneously.
