Dr Petrus Arnoldus Kotze (!Kui : tan nja)

Dr Petrus Arnoldus Kotze, also known as Arnolous P. Kotze, P.A. Kotze, and by his indigenous name !Kui : tan nja, holds a profound identity as a South African traditional healer and practitioner. He is formally recognised within the |Xam Ka! Ke! Nation for carrying the inherited spiritual and herbal healing knowledge of the |Xam people. His indigenous lineage and identity have been officially affirmed by Elder Magdalena Adolf of the Nama communities, acting specifically within the sphere of spiritual and herbal healing.

This formal recognition was granted with the direct consent of Paramount Chief Sedas Kleinschmidt, the National Leader of the |Xam Ka! Ke! Nation. The recognition serves as a testament that Dr Kotze carries the inherited abilities and qualities required to nurture and serve the spiritual and herbal healing knowledge system of the |Xam nation.

He combines this deep-rooted First Nation identity with formal medical training, having successfully completed the Basic Ambulance Course at the Transvaal Ambulance Training College in May 1991.

Lady Genna (Dr Bobo)

Lady Genna, known professionally in her practice as Dr Bobo, carries the identity of an experienced South African traditional practitioner who actively elevates indigenous knowledge onto broader, cross-cultural platforms. Her professional identity is defined by representing South Africa’s rich indigenous healing traditions in vital dialogues alongside international counterparts, researchers, academics, and policymakers.

This role was recently highlighted during her attendance at the inaugural India–South Africa Traditional Medicines Symposium in Durban, where she represented the intersection of indigenous knowledge systems and contemporary healthcare.

Lady Genna’s work directly embodies the core values of !Xam Kwasi !Gixa — Healers and Herbalists. Her identity as a practitioner is fundamentally tied to the active recognition, preservation, and responsible advancement of traditional knowledge systems to ensure community well-being.
