The evidence in words
The verdict
For mouth/peptic ulcers, DGL (Licorice) earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Older data
How it might work
It supports mucosal defense and mucus production in the stomach lining; removing glycyrrhizin avoids licorice's mineralocorticoid effects.
How to use it
Chewable DGL before meals for reflux/dyspepsia.
Safety & cautions
DGL is safe; regular licorice is not (hypertension, hypokalemia) — use the DGL form.
Bottom line
A useful, gentle option for heartburn and ulcers — but only as DGL. Never use high-glycyrrhizin licorice for this.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
