Formulation And Evaluation of Hibiscus Tea Granules Powder

The present study aimed to formulate, develop, and evaluate a herbal tea granule preparation composed of Hibiscus rosa-sinensis (Java), Zingiber officinale (Ginger), Elettaria cardamomum (Cardamon), and Stevia rebaudiana (Stevia), targeting potential antidiabetic effects. Each of these herbs has been traditionally recognized for its antidiabetic properties, and their combination was hypothesized to exert enhanced synergistic effects. A total of nine formulation, differing in the properties of herbal components. Hibiscus rosa-sinensis has also been widely used in herbal teas and beverages. Several studies conducted using animal models have evaluated the antidiabetic and antioxidant potential of the Hibiscus flower petals and leaves. The optimized formulation was subjected to comprehensive evaluation, including phytochemical profiling, antioxidant assays, antidiabetic and organoleptic analysis (taste, color, aroma, and overall acceptability) and assessment of physical parameters (moisture content, bulk density, and particle size).
