  • N.B!

  • Glycyrrhizin increase fluids and sodium retention so decrease potassium ,so a person with cardiac problems and hypertension must avoid Licorice

  • Through licorice lovers in the U.S.A rarely eat enough glycyrrhizic acid to get a blood-pressure boost.

  • European physicians are now debating whether moderate doses of natural licorice have a significant hypertensive effect.

  • Glycyrrhizic acid, which makes up from 4 to over 20% of the root, is not the only biologically active molecule.

  • About 300 different polyphenols, which make up 1 to 5% of the root, are suspected antioxidants, perhaps even cancer-fighting compounds.

  • Licorice helps heal ulcers by inactivating 15-hydroxyprostaglandin dehydrogenase in the stomach lining. As with cortisol in the kidney, licorice locally extends the life of prostaglandins that protect the stomach wall.

  • The effect on prostaglandins may also explain why licorice helps soothe a cough. The extract added to some cough drops may affect the prostaglandins that release mucous.

  • But getting in the cogs of bio-regulation pathways isn't always beneficial.

  • Because glycyrrhizic acid allows cortisol to stick around in the distal tubules of the kidney, cortisol binds to a protein that causes the kidney to retain sodium longer than it normally would, increasing blood pressure.

  • Other effects of high licorice consumption include water retention, headaches, lethargy, and, in massive amounts, heart failure.
