Antacid
Eat two teaspoons of menthol toothpaste mixed with cold water.
Antibacterial Ointment
Use honey to discourage infection and promote healing. (it’s a natural antibacterial agent). Spread it over the surface of minor cuts, burns, abrasions, and frostbite (but not directly in a wound) and cover with gauze.
Bandage
Cut a thin strip of fabric out of a T-shirt (snip in a circular pattern around the shirt to get the longest dressing possible).
Cervical Collar
No SAM splint? Roll a bulky jacket or fleece, leaving the sleeves out, and wrap it around the patient’s neck (see left). Tie it in place with the sleeves. Or cut a foam pad into a collar and tape it in place.
Cold Pack Soak the injury in cold water, or wrap soaked bandannas or cotton T-shirts around the site.
Irrigation Syringe Force water out of a hydration tube or squeeze a zip-top bag with a pinhole poked in it.
Medical Gloves Put your hands inside clean zip-top bags.
Sling Pull the bottom of the patient’s short-sleeve shirt up and over the injured arm and pin it to the front with two safety pins. Long-sleeve shirt? Pin the sleeve of the injured arm (with the arm in it) to the shirt.
Wound closure strips Cut 1/4-inch-long strips of duct tape; punch pinholes to let fluid drain.

Cleanest water for washing a wound = urinate on it.
That would help sanitize, though I'd take hand sanitizer over urination. The honey technique works well if you have it.
