DGL vs regular licorice?

DGL has the glycyrrhizin removed, so it doesn't raise blood pressure or drop potassium. Use DGL for daily gut support; reserve whole licorice for short courses — throat, formula harmonizer, adrenal-type fatigue after clinician review.

How long can I take whole licorice?

Most herbal traditions limit whole-root licorice to 4–6 weeks at a time, with breaks. Avoid it entirely with high blood pressure, heart disease, kidney disease, low potassium, or in pregnancy.

Why does licorice raise blood pressure?

Glycyrrhizin inhibits 11β-hydroxysteroid dehydrogenase type 2 — the enzyme that clears cortisol from mineralocorticoid receptors in the kidney. Cortisol builds up there, mimics aldosterone, and drives sodium retention and potassium loss. The effect is dose- and time-related; small culinary amounts are fine; daily strong tea is not.

Is licorice tea safe every day?

Not the whole-root tea. DGL preparations are safe long-term; a strong daily whole-root decoction for months at a time can drive blood pressure up and potassium down, especially in adults over 60 or anyone on diuretics.
