Formulation and evaluation of herbal antioxidant face cream of Nardostachys jatamansi collected from Indian Himalayan region

Objective: To prepare and evaluate a herbal antioxidant face cream which is made by the ethanol extract of Nardostachys jatamansi (Valerianceae). Methods: Antioxidant activity of ethanol extract was assessed by previously reported 2, 2-Diphenyl-1-picrylhydrazyl method. By discovering different types of formulations, such as oil in water, we were able to create several face creams respectively classified from F1 to F6, by incorporating different concentrations of stearic acid and acetyl alcohol. The evaluation of all formulations (F1 to F6) has been done by the analysis of different parameters like pH, viscosity, spread ability and stability. Results: An ethanol fraction analyzed from a sample of Nardostachys jatamansi showed a significant antioxidant activity with an IC50 value of 58.39.μg/mL while for ascorbic acid the IC50 value was 46.68 μg/mL. Among the six formulations (F1-F6) F5 and F6 showed good spread ability, good consistency, homogeneity, appearance, pH; there is no proof of a separation phase and ease of removal. Also the formulations F5 and F6 showed no redness or edema or erythema and irritation during irritancy studies. Conclusions: These formulations can be safely used on the skin. Hence, the study suggests that the composition of extract and the base of the cream F5 and F6 are more stable and safe, but it may produce synergistic actio
