Modern indispensable medicals for the bush or off grid.
These are prudent to have on hand. Not necessary, but prudent.
Polysporin is effective in treating debilitating foot infections that you don't have the time or resources to heal on their own. Raw garlic is said to produce the same effect but will burn your skin if left there.
Sutures—I've used these to keep down a flap. A good Band-Aid or butterfly Band-Aid will do just as well until the flesh catches and heals, and you may be lucky enough to be left with a killer scar, but probably not if you do it right.
Flesh wounds will be fine and rarely need sutures. Keeping the wound closed with butterfly-style bandages will be fine. If you sever a tendon, it is critical to get professional medical attention to reattach the connection. WITHOUT REGRET—DO NOT BE A HERO WITH THIS—or the connection will be lost permanently. Though, have some sterile stitchers on hand—both absorbable and non.
Band-aids—these are nearly indispensable. I don't want to have to boil a rag and reuse it.
Hydrogen peroxide will clear out tooth and gum infections. Rinse after use. It works on any surface; unfortunately, if used on skin, it dissolve it unless rinsed afterward, which defeats the purpose. Have an iodine water or swab for cleaning skin. The black charcoal is a possible alternative, but putting anything natural on a deep infection is a big risk
On that note...
Vinegar—white, apple cider, or other—is not modern, but it is and has been an effective antibacterial agent. Kills bacteria on contact and is an effective substitute if Polysporin or iodine water is not available to clean wounds. My experience is limited, and I was using ACV.
