Herbal tea can be use for therapeutic or nutritional purposes, depending on the chemical constituents\npresent. This study aims at evaluating phytochemical, physicochemical parameters and elemental\ncontents of herbal teas commonly consumed in Nigeria. Level of essential and toxic metals in medicinal\nplants is a matter of great concern all over the world. Six different brands of herbal teas were analysed\nin this study. Phytochemical screening results showed the presence of tannins, steroids, terpenoids,\nsaponins, cardiac glycosides, flavonoids, alkaloids and phlobatannins, while the physicochemical\nparameters which includes moistures content, ash, water extractive and alcohol extractive matter\nvalues ranges from 7.55 to 21.20, 5.52 to 9.28, 8.86 to 14.80 and 4.22 to 7.05%, respectively. Atomic\nabsorption spectroscopy (AAS) was used for the elemental analysis of different teas in which the\ncontent ranges from 0.83 to 2.63, 3.28 to 5.96, 7.45 to 86.67, 0.53 to 2.85 and 1.11 to 9.73 �µg/g for\nchromium (Cr), iron (Fe), manganese (Mn), Lead (Pb) and zinc (Zn), respectively. The outcome of this\nstudy serves as an important contribution to knowledge in establishing quality parameters for the\nstandardization of herbal tea in Nigeria.
