Native Americans have given much to the world, including the first aquaducts, the game of lacrosse, kayak designs, snowshoes, toboggans, hammocks, igloos and popcorn as well as being the first to cultivate the potato and avocados, even the first solid rubber balls (and ball games), among many other things.
One of those other things was a precursor to modern day aspirin, an effective pain-relieving tea made from willow bark, and Native Americans used drugs like peyote and datura to numb and desensitize patients during surgery and as analgesia in recovery, overseen by specialist healers who served life long apprenticeships in folk medicine.
Another practical thing that indigenous Americans developed was an early model disposable nappy. Animal skins were worked until soft and absorbent and lined with broad plant leaves and topped with dried mosses or grasses, so when the infant needed cleaning the whole shebang could be lifted out of the skin wrapping and discarded, and a new lining of leaves and mosses would be wrapped, loin-cloth style on the baby. Damp mosses and herbs were used to wipe the babies clean and keep them free from irritation and the anti bacterial properties prevented skin infection. Moss was also used to keep babies warm, and 'moss-bags' were the padded baby warmers of the time. An outer lining of soft leathers and inner lining of fabric would be filled with mosses and grasses for insulation, and the baby popped into the moss-bag before being laced into the cradleboard, a rigid structure made of oak by the babies father, complete with spinal support, head protection and a foot plate to prevent slipping. The tight swaddling of the moss-bag and lacing to the cradleboard is something emulated today with commercial baby swaddles and sleeping bags and slings. The dreamcatchers sold to alternative types as some kind of spiritual symbol are simply NA cradle mobiles, toys designed to hang above a cradle for a baby to focus on.
So when people in the 'civilized' nations were having limbs hacked off with dirty instruments by barbers, either fully conscious or black out drunk, many Native American tribes had specially kept instruments, sterilized with steam, used on patients that had been given anesthetics and treated with pain relief afterwards cared for by dedicated healers, and while European children were diapered in rags that weren't washed but rinsed and hung to dry which sometimes led to fatal skin infection, NA babies were being being cleaned with anti inflammatory wipes and changed with single use nappies.
