Ayurvedic Herbs vs Supplements: Not the Same Thing
Why an Ayurvedic herb in a clinic and an "Ayurvedic" supplement on a shelf are not the same product, and how rules, standards and evidence differ between India and the United States.

Two things with one name
"Ayurvedic" is used for very different products. One is a herb or formulation prescribed inside the Ayurvedic tradition, where the Ayurvedic practitioner chooses it for a person. The other is a capsule or powder sold as a dietary supplement, often named after one herb such as ashwagandha. This page explains how they differ. It is information only and does not recommend any product.The US National Center for Complementary and Integrative Health (NCCIH) describes Ayurvedic treatment as a combination of products (mainly from plants, but sometimes animal, metal and mineral material), diet, exercise and lifestyle. [1] A shelf supplement usually keeps only one piece of that picture: a single ingredient in a bottle.
Side by side
| Question | Traditional Ayurvedic medicine | Supplement sold as "Ayurvedic" |
|---|---|---|
| What is it? | A herb or classical formulation chosen within a wider plan that includes diet and lifestyle [1] | Usually one herb or extract, such as root, leaf or root/leaf extract [2] |
| Who decides? | A practitioner, in the tradition | The buyer, guided by the label and marketing |
| Rule book in India | Drugs and Cosmetics Act of 1940, amended in 1964 to cover Ayurveda, Unani and Siddha; the Ayurvedic Pharmacopoeia of India sets standards for quality, purity and strength of selected drugs [3] | Not applicable |
| Rule book in the US | Not applicable | Dietary supplement rules: no FDA approval before sale; companies must check safety and labeling themselves [2][4] |
| Evidence | Mostly traditional use, plus some small or poorly designed trials [1] | Depends on the exact extract; trials often use varied preparations [2] |
Same plant, different product
A herb name on a label does not tell you what is inside. A review of the plant chemistry of ashwagandha found that levels of withanolides (plant compounds) varied with the type of plant and the part used. [5] Researchers who tested ashwagandha supplements in trials have used a variety of preparations, which makes results hard to compare. [2] That is why this site treats evidence for one extract as evidence for that extract, not for "ashwagandha" in general.Quality problems can affect both
Quality problems are not limited to one side. NCCIH reports that some Ayurvedic preparations may contain lead, mercury or arsenic in amounts that can be toxic. [1] A study of 193 Ayurvedic medicines bought over the internet found 20.7% had detectable metals, and the share was similar for US-made (21.7%) and India-made (19.5%) products. [6] Products made under rasa shastra (a tradition of combining herbs with metals, minerals and gems) more often contained metals, 40.6% against 17.1% for others. [6] Details are in Ayurvedic products: heavy metals and product quality.If you or someone else may have swallowed a harmful amount of something, call Poison Help in the US at 1-800-222-1222 (see Poison help by country).
Practical points
- Ask a clinician or pharmacist before combining any herb or supplement with prescribed medicines. NCCIH says ashwagandha may interact with medicines for diabetes and blood pressure, sedatives, thyroid medicines and others. [2]
- Do not use Ayurvedic products to put off seeing a conventional provider about a medical problem. [1]

Frequently asked questions
Are Ayurvedic herbs and Ayurvedic supplements the same?
No. A herb or formulation in the tradition is chosen by a practitioner inside a wider plan. [1] A supplement is a packaged product, often a single extract, sold without FDA approval before sale in the US. [2]
Are Ayurvedic supplements regulated in the United States?
They are regulated as dietary supplements, not as drugs. Companies must evaluate safety and labeling before marketing, and the FDA can act after a product is on the market. [4]
Is a product made in India safer than one made in the US?
Not by that fact alone. In one study of internet-sold products, metals were found in about one in five of both US-made and India-made medicines. [6]
Does the herb name on the label guarantee what is inside?
No. Chemical levels in the plant vary by type, part and growing conditions, and trial products differ widely. [5][2]
Who should check with a clinician first?
Anyone who takes prescribed medicines, is pregnant or breastfeeding, or has liver, thyroid or autoimmune conditions. NCCIH advises avoiding ashwagandha in pregnancy and while breastfeeding. [2]

What the regulation difference means
NCCIH also notes that there is no significant regulation of Ayurvedic practice or education in the United States, and no state requires a practitioner to have a license. [1]
