IntroductionChronic kidney disease (CKD) has limited treatment options and is becoming more and more common. Since apparent evidence in the literature shows that herbs may be reno-protective, we discussed different kinds of herbal tea in relation to CKD and related disorders. MethodsThis cross-sectional study was conducted in health care centres located in a region in central Iran by enroling subjects aged 18 years and older. A self-reported questionnaire was used to evaluate the frequency and type of herbal tea drinks by participants. Anthropometric characteristics were measured and blood samples were obtained using a standard procedure. The Kidney Disease Outcome Quality Initiative (K/DOQI) guideline was the reference for diagnosis of CKD. Through multiple logistic models, the association between herbal tea drinking with CKD and related disorders was examined. ResultsOverall, 3 322 subjects were examined in this study. Three types of herbal tea were consumed by the study participants including green tea, chamomile-thyme tea, and borage tea. No statistically significant consistent associations between kidney disorders, including CKD, haematuria, albuminuria, and kidney stone and consumption of these herbal preparations were identified. ConclusionOverall, this study failed to suggest any consistent association between renal function and three categories of herbal tea in adult Iranian individuals.
