This document presents a chronological overview of key milestones in the global development, regulation, and integration of traditional medicine within health systems, as recognized by the World Health Organization (WHO) and its Regional Committees. Starting in 1974, it traces major resolutions, strategic plans, and declarations supporting the institutionalization of traditional and complementary medicine (TCM) across all WHO regions. Key moments include the adoption of the WHO Traditional Medicine Strategies (2002–2005 and 2014–2023), the establishment of the WHO Global Centre for Traditional Medicine in India (2022), and the extension of the Global Strategy through 2025. The document also references major UN frameworks such as the Declaration on the Rights of Indigenous Peoples (2007) and the Astana Declaration (2018), highlighting the alignment between traditional medicine and universal health coverage, primary health care, and sustainable development. It underscores efforts to ensure the safety, efficacy, quality, and accessibility of traditional medicine and calls for increased cooperation, regulation, capacity building, and knowledge preservation.
