Licorice for Indigestion

Indigestion, or dyspepsia, can include symptoms of fullness, pain, bloating, belching, nausea, vomiting, regurgitation, heartburn and appetite loss.
  Fifty people suffering from dyspepsia were given either licorice extract or a placebo in a double-blind fashion for thirty days. . . .
   Licorice significantly decreased total symptom score and scores for all of the above symptoms except early fullness. The licorice also significantly improved quality of life.
