Interactions

↑ risk of cardiotoxicity with cardiac glycosides ↓ effectiveness of antihypertensives ↑ potassium loss with potassium-depleting diuretics ↑ metabolism and ↓ levels of warfarin Licorice causes potassium depletion which may increase the risk of cardiotoxicity withcardiac glycoside-containing herbs (digitalis) Additive potassium depletion can occur with stimulant laxative herbs (senna)
Oral (Adults) Dyspepsia—1 mL three times daily (Iberogast — combination product with other herbs) for 4 weeks

Nursing implications

Nursing assessment

  • Assess GI function (bowel sounds, abdominal distention, and usual pattern of bowel function) before and periodically during therapy.
  • Monitor blood pressure and ECG periodically during prolonged therapy.
  • Lab Test Considerations: Monitor 17–hydroxyprogesterone concentrations, electrolytes, LDH, lipid profile, liver function tests, plasma renin, renal function test, and testosterone periodically during therapy.

Potential Nursing Diagnoses

Deficient knowledge, related to medication regimen (Patient/Family Teaching)

Implementation

  • Oral: Administration should be limited to 4 wks.

Patient/Family Teaching

  • Instruct patient to take as directed.
  • Advise female patient to notify health care professional if pregnancy is planned or suspected or if breastfeeding.

Evaluation/Desired Outcomes

  • Reduction in dyspepsia.

liquorice

A preparation from the root of a legume, usually Glycyrrhiza glabra, which contains asparagine, betaine, chalcones, choline, coumarins, flavonoids, glycyrrhizin, gums, isoflavonoids and saponins. Liquorice has a high content of glycyrrhizic acid—glucuronic acid + glycyrrhetinic acid—which is structurally similar to steroids, explaining its anti-inflammatory, antipyretic and antirheumatic effects; it is antitussive, demulcent, expectorant, laxative, sedative and reduces serum glucose and cholesterol.
 
Chinese medicine
Liquorice is used topically for abscesses and wounds, and internally for abdominal pain and spasms, alcohol and other intoxications, asthma, cholecystitis, cirrhosis, colds, coughing and wheezing, constipation, diabetes, fever, gastritis, gastric ulcers, heartburn, hepatitis, lung congestion, and sore throat.
 
Herbal medicine
In Western herbal medicine, Glycyrrhiza glabra is used topically for eczema, herpes and skin infections, and internally for arthritis, colic, constipation, cough, gastric ulcers, hepatitis and for many of the same conditions as Chinese medicine.
 
Toxicity
Excess liquorice causes mineralocorticoid excess (e.g., suppresses 11 beta-hydroxysteroid dehydrogenase and the RAA axis), with sodium and water retention, hypertension, hypokalemia and myopathy with myoglobulinuria; it should not be used in patients with glaucoma, hypertension, renal disease or pregnancy.

Sexology
Liquorice has an unsubstantiated reputation as an aphrodisiac. Its erotic power is mentioned in the Kama Sutra, and liquorice potions are recommended for “sexual vigour”. Liquorice odours are said to increase blood flow to the genitalia.
