Enhancing Immunomodulatory Properties of Javanese Turmeric (Curcuma xanthorrhiza) Kombucha against Diethylnitrosamine in Male Balb/c Mice

Kombucha is a fermented tea beverage, made by the addition of symbiotic culture of bacteria and yeasts (SCOBY). This study utilized Javanese turmeric in a concentration of 0.4% (w/v) as a kombucha fermentation medium and evaluated its immunomodulatory activity, compared to non-fermented Javanese turmeric beverage. Forty-two healthy male BalB/C mice (20-30 g, 2-3 weeks old) were divided randomly into five groups with seven mice each. The groups were fed: Normal diet; normal diet + Javanese turmeric kombucha; normal diet + diethylnitrosamine (DEN); DEN + non-fermented Javanese turmeric and DEN + Javanese turmeric kombucha. Kombuchas and non-fermented Javanese turmeric were given at dose of 0.3 mL/20 g BW/day. The mice were injected with 100 mg/kg DEN intraperitoneally. The spleen was collected and analyzed for CD4+, tumor necrosis factor α (TNF-α+), interleukin-6 (IL-6+), CD8+, CD11b+, and IL-10+. The statistical analyses included ANOVA and the Fischer’s exact test. The percentage of CD8+, CD11b+, and CD8+ IL-10+ increased significantly (p<0.05) among DEN-induced groups, Javanese turmeric kombucha and these values were higher than non-fermented Javanese turmeric. These findings verify that Javanese turmeric kombucha possessed better immunomodulatory activity compared to non-fermented Javanese turmeric
