The antioxidant activity of one herbal formulation (Freezy syrup) was evaluated in two types of free radical scavenging models i.e. (i) DPPH scavenging and (ii) nitric oxide scavenging model. The formulations responded effectively in both of the models tested. The results were also comparable to that of the standard ascorbic acid used as a standard for comparison in this present investigation. Thus, this investigation confirms the use of the Freezy syrup as an antioxidant agent.
