Licorice is very popular in the winter time taken as a tea with other herbs to help relieve sore throats, coughs, stomach aches, and help boost the immune system.  Just the thought of curling up on a cold fall or winter day with a cup of licorice tea may have a calming and peaceful effect on the mind and body!
Licorice root is one of the most commonly used herbs in traditional Chinese medicine.  Used to help harmonize the effects of other herbs and prolong their effect.  In the United States ninety percent of the licorice that in imported is used to flavor and sweeten tobacco.
Today licorice is often seen as a candy, however, that delicious candy is often not flavored with licorice at all but with anise and fennel! So don’t count on that candy having any healing value (except for maybe subduing that sweet tooth)!  Licorice root is fifty times sweeter than sugar, often used as a sweetener that can be safely consumed by most diabetics.
There are about twenty species of licorice native to Eurasia, Australia, and North and South America.  It is often found in the wild in grassy areas where the soil is more alkaline.  Licorice can be cultivated and worked into the soil to enrich it.

  • Avoid licorice in cases of high blood pressure, edema, nausea, vomiting, and rapid heartbeat. Long term use with large doses may elevate blood pressure, cause headaches and vertigo.
  • Large doses may cause sodium retention and potassium depletion.
  • Licorice root is not recommended during pregnancy or in combination with steroids or digoxin medication.
  • Continuous use is not recommended for more than six weeks.
  • The deglycyrrhized extract (which has had the glycyrrhizin removed) is safe to use, and has no side effects; however, if using licorice as an antiviral, the deglycyrrhized extract will be ineffective
