MUC5AC and gastric ulcer: This finding is consistent with previous studies that have shown that Shilajit, as a rich source of phenolic compounds, can decrease acid and pepsin secretion, reduce the gastric ulcer index, stimulate cellular growth and repair, and increase mucin secretion and carbohydrate/protein ratio (Czinner et al., 2001; Goel et al., 1990; Rajic et al., 2001; Talbert, 2004).
