Insulin sensitivity / blood sugar (Russian tarragon)

Limited Evidence

Small clinical studies show improved insulin response; rigorous large trials are lacking.

Culinary / flavor

Mixed Evidence

Used for culinary flavor; no specific health claim.

How it works

French tarragon contains volatile oils (estragole, ocimene, methyl eugenol), flavonoids, and coumarins. Estragole has both flavor and biological activity. Russian tarragon extract has been studied in research settings for insulin-sensitizing and glucose-lowering effects, with one human pilot study showing improved insulin response. Estragole and methyl eugenol have potential genotoxic effects at high doses in animal models, which has raised some safety concerns about prolonged high intake of essential-oil-rich preparations; food-amount culinary use is considered safe.

Dosage

Food-amount culinary use is well tolerated. Russian tarragon extract studies have used 1000 mg/day. No established RDA.
