Ayurveda, Homeopathy and Traditional Medicine: Use, Evidence and Safety

Who uses traditional medicine in India and the world, how other countries handle it, what the evidence and safety data say, and why the doctor needs to know.

Key Points
  • About half of Indians use AYUSH or home remedies[1]; WHO estimates about 80% of the world's population uses traditional medicine[2].
  • India hosts WHO's Global Centre for Traditional Medicine in Jamnagar[2]; China runs TCM services in almost every community health centre[3].
  • The evidence differs by system and product. Australia's national review found no reliable evidence that homeopathy works for any condition[4]; some metal-based Ayurvedic products carry real risk[5].
  • Whatever a doctor thinks of these systems, the patient is taking them. The doctor needs to know.

Who Uses Traditional Medicine?

46–53%Indians who used AYUSH or a home remedy in the past year (46.3% rural, 52.9% urban), 2022–23NSS 79th round[1]
170 of 194WHO member states that report use of traditional medicineWHO, 2022[2]
~40%Of approved pharmaceutical products derive from natural substancesWHO, 2022[2]

India has 7.52 lakh registered AYUSH practitioners[6]. In 2022 India and WHO established the WHO Global Centre for Traditional Medicine in Jamnagar, with a $250 million Indian investment[2].

How Other Countries Handle It

CountryApproach
ChinaIntegrates traditional Chinese medicine into the public system: 65,809 TCM institutions at the end of 2019, 1.16 billion TCM visits that year, and TCM available at 98.3% of community health centres and 97.1% of township health centres[3]
United KingdomNHS England told GPs in 2017 to stop prescribing homeopathy and herbal treatments, judging them of low clinical value[7]
AustraliaThe national medical research council reviewed more than 1,800 papers on homeopathy, kept 225 that met its standards, and found no reliable evidence of benefit for any health condition (2015)[4]
IndiaA separate Ministry of AYUSH; regulated colleges and practitioners; AYUSH medicines licensed under the Drugs and Cosmetics Act; a pharmacovigilance programme for AYUSH medicines[8]

Safety: What Is Known

~1 in 5Of about 200 Ayurvedic products bought online in the US contained detectable lead, mercury or arsenic: 40% of metal-based (rasa shastra) products, 17% of herbal-onlyJAMA, 2008[5]
3 of 8Patients with liver injury from single-ingredient ashwagandha in an Indian case series died; all had underlying liver diseaseHepatology Communications, 2023[9]
3,000+Adverse reactions to AYUSH medicines recorded by India's pharmacovigilance programme since 2018, none fatal according to the AYUSH SecretaryThePrint, March 2026[8]
65,000+Misleading AYUSH advertisements flagged in eight years under the Drugs and Magic Remedies ActThePrint, March 2026[8]

A small number of recorded reactions does not mean reactions are rare; it can mean they are rarely reported, especially when doctors do not know the patient takes the product.

How to Read the Evidence

  • Systems are not single treatments. "Ayurveda" covers thousands of preparations, from turmeric to metal-based bhasmas. Each needs its own evidence.
  • Natural is not the same as safe. Many modern drugs come from plants; so do some toxins.
  • Interactions matter more than ideology. A patient on blood thinners, diabetes medicines or chemotherapy who also takes a herbal product may be at risk regardless of whether the herb "works".

What This Means for 1Heath

1Heath takes no side between systems of medicine. It records what each patient takes, from every system, in the patient's own words, with official ingredients where the pharmacopoeia lists them and a flag for metal-containing preparations, so the treating doctor can decide. How 1Heath handles every system of medicine.
