Tip of Licorice Root … Safety & Interactions

Gan Cao Shao · Radix Glycyrrhizae Uralensis

Contraindications

  • Uncontrolled hypertension, edema, hypokalemia, or severe heart failure

Cautions

  • Gan Cao Shao may be used in smaller, more directional prescriptions, but it is still real licorice and can contribute to sodium retention, potassium loss, and blood-pressure elevation.
  • Cumulative exposure matters ... patients may encounter licorice from multiple formulas, teas, and supplements at the same time.

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
