About Licorice
Licorice root is a botanical used mainly in herbal supplements and, less often, in small food inclusions for flavor and its traditional anti-inflammatory reputation.
Licorice is used in pet foods and supplements primarily as a flavoring and herbal ingredient with mild demulcent and anti‑inflammatory properties rather than as a significant source of nutrients. While small amounts may help soothe the gastrointestinal tract, licorice contains glycyrrhizin which can cause sodium retention, potassium loss and high blood pressure, so it should be used cautiously and avoided in pets with heart, kidney or liver disease, hypertension, pregnancy, or when taking diuretics or corticosteroids.

Why it's used
Licorice root has a long history in herbal medicine as a demulcent thought to soothe the digestive tract lining, and formulators use it at low levels for its natural sweetness and aromatic profile rather than as a nutrient source. Its principal active compound, glycyrrhizin, has a chemical structure that resembles corticosteroid hormones, which is the basis for its traditional anti-inflammatory reputation.
Common concerns
- Pseudoaldosteronism from glycyrrhizin Research on glycyrrhizin metabolism shows it inhibits an enzyme that normally breaks down cortisol in the kidney, and the resulting cortisol buildup can drive sodium retention, potassium loss, and elevated blood pressure with prolonged or high-dose exposure.
- Duration-dependent risk Veterinary herbal sources describe this electrolyte and blood pressure effect as tied to dose and duration, with some recommending licorice root not be used continuously beyond a couple of weeks without veterinary guidance.
- Underlying heart, kidney, or endocrine conditions Because the mechanism involves sodium and potassium handling, licorice root is a topic to raise with a veterinarian for pets with existing heart, kidney, or liver disease, or those on diuretics or corticosteroid medication.
Also relevant
Deglycyrrhizinated licorice (DGL) is a processed form with the glycyrrhizin removed, marketed specifically to reduce these electrolyte and blood pressure effects while retaining other traditional uses.
