The practice can be called different things for different iwi (tribes) but in basics is called Tara Korohū (Vaginal steaming).
Māori use a umuroa (steam oven) to cook food but also Tohunga (spiritual healers/traditional doctors) would provide medicinal plants to be placed underneath hot stones and have men or women sit above covered in a traditional cloak to treat different ailments ranging from rheumatic issues, skin issues etc. This practice also happened often after childbirth, women would also bathe in a river as birth would take place outside or in a specially made hut and then have a steam bath.
