Treating injuries in the wilderness

The man has multiple injuries, the most notable one being an arrow to the calf, which he unceremoniously ripped out.

Even back then, combat arrows were typically broadheads - i.e., with an oversized, cutting head that isn't removed easily. Anyway, just something to keep in mind.

Otherwise, just Google "medieval wound care". There's even a good article on Wikipedia. Unless your story really requires some mystical and arcane treatments (which seem to be a bit overdone in historical fiction), I think the basics were fairly well-understood: stitching if possible, bandages and splints, amputation before gangrene sets in if the damage is too grave. Amputations were pretty common. Things like spiderwebs, honey, clay, and oil were sometimes used as antiseptic dressings, with varied results. Alcohol was known to have antiseptic properties, too.

There was also a lot of mystical quackery, but that was related mostly to the treatment of more exotic conditions. Wounds were pretty straightforward and easy to reason about, even in the ancient times.
