some common weeds are among the best herbal remedies I have found. plantain makes for a great poultice for bites and stings. mash it up and apply it as a compress. dandelion sap relieves bee stings better than anything else I have found. Jewel weed/touch me nots makes for the best poison ivy remedy, too.
