Abstract
This work examines the commercialization trajectories of herbal ingredients from southern Africa, tracing their evolution from traditional medicines to established natural (medicinal) products in global markets. Historically, the success of such ingredients depended on entrepreneurship, serendipity, colonial interests, and the absence of regulatory barriers. Remedies like Pelargonium sidoides (Umckaloabo), Harpagophytum spp. (devil's claw), and Agathosma spp. (buchu) transitioned from indigenous use to recognized phytopharmaceuticals and functional botanicals in Europe and the United States. However, modern regulatory frameworks have complicated market access, raising costs and deterring investment. While access and benefit-sharing agreements safeguard traditional knowledge at its origin, protecting proprietary manufacturing knowledge remains a challenge, further discouraging innovation. Through 10 case studies spanning 4 centuries, this investigation highlights recurring themes affecting commercialization: identity and quality, supply chain management, efficacy and safety, regulatory environments, intellectual property, and respect for traditional knowledge. Each case illustrates how these factors interplay.
