Ayurveda is a traditional system of medicine from India with a long history, but modern evidence that its remedies work is limited and uneven. Some practices, like diet and daily routine, overlap with ordinary health advice. Some herbal products have been studied only lightly, and a few have documented safety problems.
Why is Ayurveda in the news?
Ayurveda Day is an annual observance promoted by India's Ministry of Ayush, which began it in 2016. Since a 2025 government notification, it falls on September 23 each year, and the 11th Ayurveda Day was held on September 23, 2026 (Organiser).
What does Ayurveda claim?
Ayurveda holds that health depends on balance among three doshas, which are energy types called vata, pitta and kapha. Treatment aims to restore that balance through diet, herbs, massage, cleansing routines and lifestyle changes.
The doshas are a traditional framework. They are not anatomical structures, and no modern test measures them. That does not make every Ayurvedic practice useless, but it does mean the underlying theory can't be checked the way a blood pressure reading can.
What does the research show?
The evidence is sparse and mixed. The U.S. National Center for Complementary and Integrative Health (NCCIH) says that few well-designed clinical trials and systematic research reviews suggest Ayurvedic approaches are effective. It notes that a few studies suggest Ayurvedic preparations may help with osteoarthritis pain and type 2 diabetes symptoms, but that most of those trials are small or not well designed, and that there is little scientific evidence on Ayurveda's value for other health issues (NCCIH).
There are individual trials. In one randomized, double-blind trial of 440 people with knee osteoarthritis, two Ayurvedic herbal formulations performed about as well as glucosamine, a common supplement, and celecoxib, a prescription anti-inflammatory drug, over 24 weeks (Chopra et al., 2013, Rheumatology). A single trial of this kind is a starting point. It does not show that the treatment is effective, particularly because NCCIH says it is still uncertain whether glucosamine helps knee osteoarthritis symptoms (NCCIH).
Lifestyle elements, such as regular meals, sleep routines and gentle movement, are harder to credit to Ayurveda specifically. Research supports those habits in general, whatever tradition recommends them.
Is Ayurveda safe?
The main documented risk is contamination. In a 2008 study in JAMA, researchers bought Ayurvedic products online and tested them. Of 193 products tested, 20.7%, or about one in five, contained detectable lead, mercury or arsenic (Saper et al., 2008). An earlier JAMA study from 2004 found a similar share, 14 of 70 products, among products bought in the Boston area (Saper et al., 2004).
Some Ayurvedic preparations include metals, minerals or gems, and the U.S. Food and Drug Administration warns that the presence of metals in some Ayurvedic products makes them potentially harmful (NCCIH). The FDA also does not have the authority to approve dietary supplements before they are marketed (FDA).
Individual herbs carry their own concerns. Ashwagandha, an herb used in Ayurveda, has been linked to liver injury in a case series of five patients from Iceland and the United States (Björnsson et al., 2020, Liver International). None developed liver failure, and liver tests returned to normal within one to five months in four of them.
Turmeric and its compound curcumin are also sold as supplements. NCCIH says highly bioavailable curcumin formulations may harm the liver, and liver damage has been reported in some people who took them (NCCIH).
How can someone approach it more carefully?
Tell every clinician about any herbal product being taken, since some herbs and medicines interact in harmful ways (NCCIH). Never stop or swap out prescribed medication or treatment for an herbal remedy. Anyone with a health condition should talk with their regular health care provider before using Ayurvedic products (NCCIH).
What is a sensible next step?
Before buying any Ayurvedic supplement, write down the product name and ingredients, then bring the list to a pharmacist or doctor and ask whether it could interact with anything else being taken.

Our editors' take
The article separates two questions that usually get blurred: whether the theory is testable, and whether a given product does anything. The doshas fall in the first group. No instrument measures vata, pitta or kapha, so the framework can be respected as tradition without being treated as a finding. The products are testable, and the record there is thin. One trial of two herbal formulations against glucosamine and celecoxib, Chopra and colleagues in 2013, is a starting point. Glucosamine is itself a modest benchmark, so matching it is like beating a slow runner. The safety evidence is firmer than the benefit evidence, which is an awkward position for any product. Saper's 2008 JAMA work on metal contamination is the reason we would take the pharmacist advice seriously. A pharmacist can at least check what is in a product and what it might interact with; that is a check on contents, not a verdict on benefit.
