Yoniverse Steam | Plant Powered Female First Aid Use me with Beauty Tofu’s Yoni Potion - Yoni Duo of Dreams ! Yes, you did hear correctly – this is really about steaming your vagina, your yoni, your YONIVERSE ! Yoni steaming involves exposing the vagina to steam to cleanse it and enhance its health. How does is work? The warmth of herbal steam softly permeates the exterior of the vagina. During the process, which should last for about 20 to 45 minutes, the steam dilates the blood vessels, increasing blood circulation, providing oxygen, and relaxing the pelvic floor muscles.Yoni steams bring heat to the womb. The use of specific herbs adds layers of different healing benefits, depending on the health condition being treated.
