Traditional medicine practiced by the Karo ethnic group, who live in the highlands of North Sumatra, Indonesia, is an integral part of their social and cultural life. With ancestral knowledge, the Karo people utilize medicinal plants from home gardens, agricultural lands, forests, and local markets. Remedies such as parem, tawar, Karo herbal oil, oukup, and sembur are still being produced and traded today, reflecting the philosophy that nature provides solutions for all ailments. Historically, Karo traditional medicine has been enriched by the exchange of knowledge and medicinal plants along the Maritime Silk Road, now part of the Belt and Road Initiative (BRI), which influenced local practices. Despite its cultural and economic significance, the production and trade of these remedies are constrained by limited resources and restricted market access. However, the BRI now provides opportunities to enhance the global reach and sustainability of this heritage. A cross-sectoral approach involving natural resource conservation, halal certification, modern innovation, and strengthened global promotion can establish Karo traditional medicine as a high-value health solution, bridging cultural traditions and global markets.
