Objective This study aimed to evaluate the clinical effect of fermented raw potato juice on improving symptoms of gastric disease. Methods Fifty patients diagnosed with gastric disease at our hospital from March 22 to April 7, 2023, were enrolled. They consumed 100 mL of fermented raw potato juice twice daily on an empty stomach (before breakfast and dinner or one hour before lunch and dinner) for 6 consecutive days. Efficacy and adverse reactions were compared. Results All 50 patients completed the study. After the intervention, the total symptom score significantly decreased from 10.9 ± 6.15 to 3.1 ± 3.20 (P < 0.01). The effective rates for 16 major symptoms ranged from 66.67% to 100%. Except for periodic and rhythmic epigastric pain, the scores of the other 15 symptoms showed significant improvement after the intervention (P < 0.05 or P < 0.01). No adverse reactions were reported, and participants expressed high satisfaction with the taste of the juice. Conclusion In conclusion, consumption of fermented raw potato juice can help alleviate symptoms of gastric disease without significant adverse effects.
