Traditional medicine

Traditional medicine encompasses a diverse range of healing systems, including ancient practices such as Traditional Chinese Medicine (TCM), Ayurveda, Unani, and various indigenous healing traditions. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skill, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health and the prevention, diagnosis, improvement or treatment of physical and mental illness."¹ It includes practices like herbalism, acupuncture, manual therapies, and mind-body interventions. Traditional medicine is often contrasted with modern or allopathic medicine, but the boundary is not always clear, as many modern pharmaceuticals derive from traditional remedies.

Traditional medicine is widely used across the globe, with the WHO reporting that about 80% of the world's population relies on it for primary health care in some regions.² In many countries, traditional medicine is formally integrated into national health systems. For example, China has a well-established system of TCM hospitals and research institutions, and India has a dedicated ministry for Ayurveda, Yoga, Unani, Siddha, and Homeopathy (AYUSH). The WHO's Traditional Medicine Strategy 2014–2023 encourages member states to integrate traditional medicine into their health policies and to ensure its safety, efficacy, and quality.³ However, integration varies widely, from full recognition to marginalization, and often faces challenges such as lack of regulation and standardization.

Scientific research on traditional medicine has grown, with many studies evaluating the efficacy and safety of herbal remedies and other modalities. For instance, artemisinin, a drug derived from the traditional Chinese herb Artemisia annua, is a frontline treatment for malaria and was recognized with the Nobel Prize in Physiology or Medicine in 2015.⁴ However, many traditional practices lack rigorous evidence, and some can be harmful. The WHO has documented issues such as contamination, adulteration, and toxicity of herbal products, and emphasizes the need for pharmacovigilance.³ Regulatory frameworks vary; in the United States, herbal supplements are regulated as dietary supplements, not drugs, which means they are not subject to the same pre-market approval as pharmaceuticals.

Traditional medicine is deeply embedded in cultural identities and often serves as a primary healthcare option in low-income communities. It is also a significant economic sector; the global market for traditional medicine and herbal products is estimated to be worth billions of dollars annually.⁵ Many indigenous communities rely on traditional medicine for both health and cultural preservation. The WHO has recognized the importance of protecting traditional knowledge and ensuring equitable benefit-sharing when such knowledge is used in commercial products, aligning with the Convention on Biological Diversity.⁶ However, there are concerns about biopiracy and the exploitation of traditional knowledge without fair compensation to originating communities.

Beyond well-known systems, traditional medicine includes lesser-known practices such as traditional bone setting, cupping therapy, and leech therapy, which are still used in various regions. For example, leech therapy (hirudotherapy) has been used for centuries and is now being revisited in modern surgery for its anticoagulant properties.⁷ Another niche area is the use of traditional medicine in veterinary care, known as ethnoveterinary medicine, which is practiced in many rural areas.⁸ Additionally, some traditional remedies have led to unexpected discoveries: the anti-cancer drug paclitaxel (Taxol) was derived from the Pacific yew tree, a plant used in traditional medicine by some Native American tribes.⁹ The field also includes mind-body practices like yoga and meditation, which have gained global popularity and are now integrated into many wellness programs.
