Medicine wheels, known also as sacred circles or sacred hoops, are monuments constructed by certain Native American cultures by laying stones in a particular pattern on the ground. The most basic pattern, which is followed by the majority of medicine wheels, consists of a center of stones, which is connected to an outer ring by ‘spokes’. Medicine wheels were, and still are, constructed for healing purposes. It may be mentioned that this ‘healing’ should be understood within the context of inner spiritual energy and enlightenment, rather than the taking of drugs or herbal remedies. Apart for that, such wheels are speculated to have been made for astronomical, ritual and teaching purposes as well.
