Can natural remedies (e.g. plants, spices, roots) be utilized in rudimentary wound care? if so, what are the best options?

Yes, many options: Medicinal herbs have been successfully used to treat wounds for thousands of years. Herbs can be antimicrobial, relieve pain and swelling and speed healing. Dozens of herbs can help, including calendula, aloe vera, plantain, yarrow and comfrey. Health food stores sell salves containing these herbs.
