Tea, food or medicine?
"Ayurvedic tea" is a marketing label, not a defined product. It can mean a pleasant mix of kitchen herbs and spices, a single herb such as tulsi (holy basil), or a blend sold with health claims. In Ayurveda, herbal water preparations are also made as medicines by practitioners; see forms of Ayurvedic preparations. This page covers retail teas. It gives no recipes or amounts, and it does not match teas to a body type.Pregnant, breastfeeding, taking prescribed medicines, or giving a tea to a child? Check with a clinician or pharmacist first. See interactions, pregnancy and children.
What research shows
| Tea or herb | What the source found | Evidence label |
|---|---|---|
| Tulsi (holy basil) | A systematic review found 24 human studies on metabolic disorders, cardiovascular disease, immunity and neurocognition. All reported favourable outcomes and none reported significant adverse events, and the authors say further studies are needed on mechanisms, dose, dose form and who benefits [1] | Promising but limited |
| Ginger, fennel, cumin, coriander | Covered on separate pages | See Ayurvedic spices and digestive teas |
| Tulsi as a tea specifically | We did not find a trial of tulsi tea itself in the review we read; it covered "ingestion of tulsi" in several forms [1] | Proper evidence not found for tea as a form |
Two cautions on the tulsi review. First, "all studies favourable" is a pattern that can signal small studies and selective reporting, so it should not be read as proof; the authors themselves call for more research. [1] Second, the studies used different forms and doses, so they say little about a tea bag. Individual guides: tulsi in Ayurveda and tulsi tea.
Buying and reading a tea label
Look for the botanical name of each herb, the plant part and a named maker, as described in reading an Ayurvedic product label. General guidance is in herbal tea quality and labels. If a product mentions metals or "bhasma" (a traditional metal preparation), read heavy metals and product quality before going further.Frequently asked questions
Is Ayurvedic tea healthier than ordinary herbal tea?
We found no study comparing them. The label "Ayurvedic" does not guarantee a different or better product.
Does tulsi tea reduce stress or blood sugar?
The review reported favourable outcomes in studies of tulsi on stress and metabolic problems, but it did not isolate tea and asks for more study. [1] Evidence is promising but limited.
Are herbal teas safe to drink every day?
Not automatically. Metals were found in all commonly consumed herbal teas in one review, and individual herbs such as licorice carry their own cautions. [2][3]
Can I give Ayurvedic tea to a child or while pregnant?
Ask a clinician first. NCCIH advises that people who are pregnant or nursing consult their provider because some Ayurvedic products may be harmful. [6]
Do herbal teas interact with medicines?
They can. Tell your pharmacist what you drink regularly. See natural remedy medicine interactions.

Safety and quality
- Metals. A systematic review of 49 papers found that all commonly consumed herbal teas contained metals and none met WHO requirements, though more than 70 percent of the health risks were acceptable; the risks from arsenic and lead were considerably higher than for other metals, and the authors recommended preventing consumption of low-quality herbal teas. [2] This was a review of herbal teas generally, not Ayurvedic blends specifically.
- Licorice (mulethi). Licorice root is a common ingredient in herbal blends. A 2026 review calls licorice-induced pseudohyperaldosteronism, with low potassium and high blood pressure, a frequent adverse effect of licorice-containing Japanese Kampo medicines. [3] Read the label for licorice and see licorice root tea.
- Teas sold for "detox" or weight loss. Treat these as claims to check, not benefits. See Ayurvedic detox and cleanse claims and detox and weight loss teas.
- Regulation. In the US, the FDA says it is not authorized to approve dietary supplements for safety and effectiveness before they are marketed. [4] Disease claims on Ayurvedic products make them illegally marketed there. [5]
