This study evaluated the stability characteristics of oil-in-water emulsions prepared using purified glycyrrhizin (PG) or a non-purified glycyrrhizin-rich extract from liquorice root (LRE) at equivalent concentrations (0.01−0.1%, w/w). PG-stabilized were sensitive to acidic pH (< 5), NaCl addition (≥ 50 mM), and freeze-thaw cycles. Consequently, they showed signs droplet coalescence upon storag...

the protective effect of liquorice plant extract (lpe) on ccl4-induced hepatotoxicity in common carp was evaluated using fifty adult carps. the fish were cultured in a standard environment in terms of water flow rate, oxygen, ph, food and temperature. the fish were assigned into 5 groups (n = 10) as control, sham, and tests. the test groups were pre-treated for 3 h with various concentrations o...

Ninety-six patients with gastric ulcer were randomly allocated to treatment either with deglycyrrhizinised liquorice or placebo. After four weeks no differences were found between the treatment groups in the proportions with complete healing, whether assessed by gastroscopy or radiology, or in the percentage reduction in ulcer area, or in clinical improvement.
