Vaginal steaming, sometimes shortened to V-steaming, and also known as yoni steaming, is an alternative health treatment whereby a woman squats or sits over steaming water containing herbs such as mugwort, rosemary, wormwood, and basil. It has been practiced in Africa (Mozambique, South Africa), Asia (Indonesia, Thailand), and Central America (among the Q'eqchi' people). There is no evidence that vaginal steaming has any benefits, while there is evidence to show it can be dangerous.
