Abstract

Herbal distillates are used in abundance as a beverage in Iran. The main purpose of this study was to determine the amount of fluoride in plant distillates.This study was performed for the first time in Iran. Sixty samples of twenty types of most commonly used herbal distillates(fennel, fenugreek, ginger , camel's thorn, cardamom, rice bran, citrus, licorice, aloe era , eglantine , coriander , lemon balm, hawthorn , pussy , cinnamon, thyme, rosewater, alfalfa, olive leaf, malva)were selected. Fluoride content of each sample was measured three times with SPANDS method by spectrophotometer.(model Dr4000, HACH Co.).The lowest concentration of fluoride were found in ginger, eglantine, hawthorn, thyme, licorice, olive leaf (mean = 0 mg/l) and the highest in alfalfa (mean= 0.32)samples respectively. The survey results showed that fluoride levels in the samples is low and there is no risk of fluorosis.
