PREPARATION AND CHARACTERIZATION OF A POLY-HERBAL TEA WITH EFFECTIVE ANTIOXIDANT PROPERTIES

Abstract

Many herbal teas consist of poly-herbal materials that are often folk recipes with known health benefits. Poly-herbal teas containing the leaves of Moringa oleifera, Zingiber officinale and juice of Citrus limon were developed and evaluated for its physicochemical and stability properties. The herbal tea generally showed good physicochemical properties such as organoleptic properties, excellent flow, optimal ash value and moisture content. It showed stability properties that are characteristic of a good finished herbal product. The tea also showed effective free radical scavenging properties similar to that of ascorbic acid and consistent with its antioxidant benefits. Some of its physicochemical and antioxidant properties were diminished when stored in a stress environment. Formulating the poly-herbal recipe of M. oleifera, Z. officinale and juice of C. limon into herbal tea is an effective means of presenting the herbal medicine for use.
