If someone has swallowed an Ayurvedic or other remedy and is very unwell, or a baby or young child has been given a product that may contain mercury or lead, seek emergency care. In the US call 911, or Poison Help at 1-800-222-1222. [1] See poisoning: what to do first and poison help by country. Bring the product and its packaging.The concern in one paragraph
The US National Center for Complementary and Integrative Health (NCCIH) says some Ayurvedic preparations may contain lead, mercury or arsenic in amounts that can be toxic. [2] This is a statement about specific products, not about the whole tradition, which also includes diet, daily routines and plant-based remedies. The concern is strongest for preparations that deliberately contain metals and for products made or sold with little quality control.Evidence labels used on this page: evidence of harm (documented contamination and poisonings), established (that these metals are toxic), traditional use only (traditional purification claims).
Why some products contain metals
Rasa shastra is the branch of Ayurvedic pharmacy that deals with formulations made with minerals and metals, particularly mercury (parad). [3] In the tradition the metals are put through a purification step (shodhana) before use. [4] Whether a particular finished product is safe cannot be assumed from that tradition; it has to be tested. A product can also be contaminated through raw materials or manufacturing even when no metal was meant to be in it. A 2024 review notes that Ayurvedic medicines frequently lack standardized manufacturing processes and quality control. [4]Headline findings
- A JAMA study of 193 Ayurvedic medicines bought online found that 20.7% contained detectable lead, mercury or arsenic, with a similar share in US-made (21.7%) and Indian-made (19.5%) products. [5]
- Products made under rasa shastra had metals more often than other products (40.6% versus 17.1%). [5]
- Of the metal-containing products, 75% claimed Good Manufacturing Practices, so that label claim did not show a product was clean. [5]
- A US agency warning says there are no FDA-approved Ayurvedic products and that these products typically are not labeled as containing lead, mercury or arsenic. [6]
- Health Canada found high levels of arsenic, mercury or lead in 14 of 15 products seized from one clinic, and prescription drugs in three of them. [7] [8]
These figures come from samples that were bought, seized or investigated. They do not say how common metals are across every product on sale today, and we did not find a recent market-wide survey.
Practical guidance
- Be most cautious with anything described as bhasma, rasa, sindura, parad, or as a "mineral" or "metal" preparation, with products shipped from overseas, and with products that have no ingredient list.
- A "natural" or "GMP" label does not prove a product is free of metals. [5]
- Where regulators run a product register, check the product against it. For example, Victoria's health department (Australia) says an AUST R or AUST L number on the packaging indicates a product can be legally supplied there. [9]
- Do not give these products to babies or children, or use them in pregnancy, without a clinician's advice. [10]
- Tell your doctor or pharmacist which product you use. Whether to check blood levels is a decision for your clinician. [11] Do not start a "detox" or chelation product on your own.
- Do not use Ayurvedic medicine to postpone seeing a conventional health care provider about a medical problem. [12]

Frequently asked questions
Are all Ayurvedic products contaminated?
No. In the 2008 online study about one in five contained metals, so most did not. [5] But you cannot tell which from the label.
Does traditional purification (shodhana) make metals safe?
The tradition describes purifying metals before use. [4] Product testing still found toxic levels in some rasa shastra products. [5] [15]
Are US-made products safer than imported ones?
Not necessarily. The 2008 study found a similar share with metals in US-made (21.7%) and Indian-made (19.5%) products. [5]
Why do health agencies warn about children?
Children are particularly susceptible to lead because of higher absorption through the gut and effects on the developing nervous system. [16] Health Canada also lists children among those most susceptible. [10]
How can I report a bad reaction?
See reporting a problem with an Ayurvedic product. In the US the FDA asks that products suspected of containing heavy metals be reported to its MedWatch program. [1]

Regulation, by country
- United States: the FDA says Ayurvedic products as a category are not specifically defined under US law, and depending on the circumstances they could be regulated as drugs, dietary supplements, foods, cosmetics or devices. [13] Dietary supplements are not approved by the FDA before they are sold. [14]
- Australia (Victoria): medicines including Ayurvedic ones must be on the TGA's national register; products without an AUST number may be unregulated. [9]
- Canada: Health Canada says unauthorized health products have not been assessed for safety, effectiveness and quality. [7]
