The Effect of Black Tea (Camellia sinensis (L) Kuntze) on Pediatrics With Acute Nonbacterial Diarrhea

Abstract

We aimed to evaluate the antidiarrheal effect of black tea in pediatric patients with acute nonbacterial diarrhea. This single-blind randomized clinical trial study was performed on 2 to 12-year-old patients, with acceptable criteria for acute nonbacterial diarrhea in Shiraz, Iran. In total, 120 patients took part in this study. Blocked randomization method was used to allocate them into 2 groups of intervention (black tea tablet + standard treatment) and control group (standard treatment; 60 patients in each). Frequency of defecation, volume, and consistency of stool were registered on arrival and 24 hours later. We used χ2 test, t test, and Mann-Whitney U test. After a 24-hour follow-up, the proportion of patients with formed stool was higher in the intervention group when compared with the control group ( P < .001). There was a significant difference between the mean number of defecations per 24 hours in both groups, after treatment ( P < .001). We found a possible antidiarrheal effect of black tea.
