Vaginal steam may be a method of herb administration because of how permeable the vaginal mucus membrane is and how vaginal blood vessels connect to the body’s circulatory system. If herbs are indeed absorbed during a steam session, this may help to target specific health imbalances through administering herbs with specified properties.
For example, instead of oral antibiotics to treat infections connected to the reproductive organs and adjacent anatomy, one might be able to observe comparable success with anti-bacterial herbs administered via vaginal steaming.
