Origin.
Dudu-Osun finds its origin with the Yoruba people in Nigeria, Benin and Togo.
The name Dudu Osun is derived from two Yoruba words “"osun” (camwood) a"nd "“dudu”" ("black)." This translates as “camwood soap”, although “osun” can also be translated as "“ose”" which means soap. This translates as “black soap”.
Manufacturing Process.
Generally, traditional black soap is made from the ash of locally harvested barks and plants.
Dudu-Osun, however, derives its primary ingredient from Camwood, a  tree from West Africa. The tree’s bark is pounded and ground into a smooth powder form, which is then made into a paste. The camwood paste is added to the rest of the mixture that includes aloe vera, lime juice, honey, etc.  This mixture is cooked and stirred till it solidifies before the soap is moulded to shape.
