This video from the World Wildlife Federation shows Himba women in Namibia harvesting omumbiri1 and making perfume. About 4 minutes long. You can read more about this project at The Nature Conservancy.
1. Omumbiri is the local name for the resin from the Commiphora wildii tree, a relative of the Commiphora myrrha tree that produces myrrh. You can read more about omumbiri resin at Anya's Garden, or at the African Aromatics page at Facebook, which is the source of this quote:
The Omumbiri is used only for perfume making among the Himba. They make both a dry powdered perfume and the ochre, butterfat mix perfume. The dry perfume mix is made up of more than 20 plants – some of which are not found in the area. Karin Knott has been trying to identify these plants – but a few are found only on the holy mountain and as she says. “I haven’t been given the privilege of going there yet.” Karen Knott [note: the plant ecologist in the video above] works in the Kunene Region for the IRDNC, a field-based, non-governmental, Namibian organisation that gives technical and financial support to the communal conservancies
