Traditional and Herbal Medicine in Kenya: Regulation, Practice, and Integration into Healthcare

Traditional and herbal medicine occupies a complex and often contentious space in Kenya's healthcare landscape. An estimated 60–80% of the population relies on traditional healers and medicinal plants for primary healthcare, particularly in rural areas where conventional medical facilities are scarce. Yet for decades, this vast sector has operated largely outside regulatory frameworks, creating risks of exploitation, unsafe practices, and unverified therapeutic claims. Kenya is now moving decisively toward formalisation, with the government unveiling plans to integrate traditional medicine into the mainstream healthcare system by 2028, supported by new legislation, research infrastructure, and quality assurance mechanisms led by institutions like the Kenya Medical Research Institute (KEMRI).

The Scale and Significance of Traditional Medicine in Kenya

Kenya's 47 ethnic communities possess rich traditions of plant-based medicine, spiritual healing, and indigenous health practices accumulated over centuries. Traditional healers — known as herbalists, traditional birth attendants, bone setters, spiritual healers, and diviners — serve as the first point of healthcare contact for millions. The World Health Organization (WHO) estimates that traditional medicine serves over 80% of Africa's population for some aspect of primary healthcare. In Kenya specifically, the ratio of traditional healers to population is approximately 1:400, compared to roughly 1:7,000 for conventional medical doctors, making herbalists the most accessible healthcare providers in many communities.

Common medicinal plants used in Kenyan traditional medicine include Aloe vera (treating burns, digestive issues), Prunus africana (prostate conditions), Warburgia ugandensis (respiratory infections and malaria), Ajuga remota (malaria treatment), and Croton megalocarpus (wound healing). The Luo, Kikuyu, Kamba, Maasai, Mijikenda, and other communities each maintain distinct pharmacopoeias refined through generations of empirical observation. This indigenous knowledge represents both a cultural heritage and a potential source of pharmaceutical innovation — several modern drugs trace their origins to traditional medicine practices across Africa.

The Legal and Regulatory Framework

The Health Act 2017

Part X of the Health Act 2017 specifically addresses traditional and alternative medicine. The Act directs the Ministry of Health to develop policies guiding the standardisation of traditional medicine and provides for the establishment of a regulatory body for traditional and alternative medicine through a separate Act of Parliament. However, this regulatory body has not yet been fully established, leaving a significant governance gap. The Act represents formal recognition of traditional medicine's role in Kenya's health system but lacks the implementing regulations needed to give it practical effect.

The Traditional Health Practitioners Bill

The Traditional Health Practitioners Bill aims to create a comprehensive framework for registering, licensing, and regulating traditional medicine practitioners. The Bill proposes establishing a Traditional Health Practitioners Council responsible for maintaining a register of practitioners, setting minimum qualification standards, enforcing a code of ethics, and investigating complaints. Critics argue the Bill's requirements may be too burdensome for informal practitioners, while supporters maintain that regulation is essential for patient safety and professionalisation of the sector.

The Pharmacy and Poisons Board

The Pharmacy and Poisons Board (PPB) currently regulates herbal products from development to sale. The Board has published guidelines for the registration of herbal products, establishing requirements for quality, safety, and efficacy that mirror pharmaceutical standards but are adapted for herbal preparations. Registration requires product identification, quality control specifications, stability data, and evidence of traditional use or clinical evidence supporting therapeutic claims. Despite these guidelines, the vast majority of herbal products sold in Kenya remain unregistered, sold through informal channels that bypass quality assurance mechanisms.

KEMRI and Scientific Validation

The Kenya Medical Research Institute's Centre for Traditional Medicine and Drug Research (CTMDR) is mandated to conduct research rationalising traditional medicine in Kenya. CTMDR researchers have investigated hundreds of plant species used in traditional healing, screening for antimalarial, antibacterial, antifungal, and anticancer properties. Notable research includes work on Prunus africana bark extract for benign prostatic hyperplasia, studies of Ajuga remota for antimalarial activity, and investigation of Kenyan plant species for anticancer and sickle cell disease applications.

The proposed Kenya Medical Research Institute Bill 2025 seeks to strengthen KEMRI's framework for traditional medicine research and commercialisation. The Bill proposes stringent quality controls, provisions for conservation of medicinal plants, safeguards against exploitation of indigenous knowledge, and penalties for false or unverified claims about herbal cures. This legislative effort reflects growing recognition that scientific validation — through biochemical screening, clinical testing, and documentation — is essential for safe integration of traditional remedies into the healthcare system.

The Path to Integration by 2028

At the Second WHO Global Summit on Traditional, Complementary and Integrative Medicine in New Delhi in 2025, Health Cabinet Secretary Aden Duale outlined Kenya's strategy to create a National Policy and a Department of Traditional Medicine by 2028. The plan envisions traditional healers working alongside conventional healthcare providers, with herbal medicines incorporated into hospital formularies where scientific evidence supports their safety and efficacy. Kenya has established a comprehensive policy framework including the Traditional, Complementary and Integrative Medicine Policy, the National Research Framework, and the Herbalists' Handbook — designed to professionalise practice and strengthen safety standards.

The Herbalist Society of Kenya, led by Dr. Lydia Kemunto Matoke, has expressed support for integration, with traditional healers indicating readiness to work with researchers and regulators. The government is also considering allowing herbal medicines in hospitals, marking a significant shift from the historically dismissive attitude of Kenya's formal healthcare establishment toward traditional practices.

Challenges and Controversies

Traditional medicine in Kenya operates in a space rife with genuine healers and outright charlatans, making regulation urgently necessary. Unregulated practitioners make unsubstantiated claims about curing HIV/AIDS, cancer, and diabetes, endangering patients who abandon proven treatments. Contamination and adulteration of herbal products — including cases of herbal medicines laced with pharmaceutical drugs like steroids or analgesics — pose serious safety risks. The unregulated market also facilitates biopiracy, where multinational pharmaceutical companies exploit indigenous knowledge without fair compensation to communities.

Conservation is another concern. Overharvesting of medicinal plants threatens biodiversity — Prunus africana is listed under CITES Appendix II due to unsustainable harvesting for the international pharmaceutical market. Kenya's forests, which harbour much of the country's medicinal plant diversity, face ongoing deforestation pressures. Balancing commercial demand, conservation needs, and the rights of communities who have traditionally used these resources requires carefully designed policy frameworks that Kenya is still developing.

The Future of Traditional Medicine in Kenya

Kenya stands at a turning point. With political commitment to formalisation by 2028, institutional research through KEMRI, and a willing traditional medicine community, the country has the ingredients for successful integration. The WHO's establishment of the Global Centre for Traditional Medicine in Jamnagar, India, provides international momentum and technical support. Success will require sustained funding for research and regulation, genuine collaboration between conventional and traditional practitioners, protection of indigenous knowledge through intellectual property frameworks, and patient safety mechanisms that weed out dangerous practices while preserving legitimate traditional healing traditions that have served Kenyan communities for centuries.
