Raw Licorice Root … Safety & Interactions

Gan Cao · Radix Glycyrrhizae

Contraindications

  • Uncontrolled hypertension, edema, hypokalemia, or severe heart failure
  • High-dose or prolonged unsupervised use

Cautions

  • Raw licorice is still real licorice ... it can retain sodium, waste potassium, raise blood pressure, and complicate cardiac disease.
  • Because Gan Cao sits in so many formulas, cumulative exposure from multiple products is easy to underestimate.

Drug Interactions

Drug Class / Substrate Mechanism Severity Source
Loop or thiazide diuretics ... additive potassium loss and arrhythmia risk
Digoxin and other cardiac glycosides ... hypokalemia may increase toxicity risk
Corticosteroids ... additive mineralocorticoid-like effects
Antihypertensives or antiarrhythmics ... electrolyte shifts may complicate therapy
