Native American medical practices and death rituals

hey guys I need some help locating sources for a paper I'm working on about Native Americans and their medical
practices and death rituals. I'm not focusing on any certain tribe or group, mostly just doing an overview. I've been
able to find a couple of good texts on death rituals but not so much on medical practices and was just wondering if anyone had any suggestions on some books or websites with good accurate info. Also I've found a couple of sites that mention the medicine wheel? Any information that y'all have would be a great help thanks in advance!
