The present study focuses on the formulation and evaluation of a herbal immunity booster syrup using Moringa oleifera leaves and lemon juice. Herbal medicines are widely used because they are natural, safe, economical, and associated with fewer side effects compared to synthetic products. Moringa oleifera is known as a highly nutritious medicinal plant rich in vitamins, minerals, proteins, flavonoids, tannins, polyphenols, and antioxidants, which help improve immunity and overall health. Lemon is an excellent source of Vitamin C and provides antioxidant and immune-enhancing properties. Honey was used as a natural sweetening agent and sodium benzoate as a preservative in the formulation.(15)

The syrup was prepared by hydroalcoholic extraction of Moringa oleifera leaves followed by formulation using suitable excipients. The prepared syrup was evaluated for various physicochemical parameters such as color, odour, taste, pH, density, viscosity, and stability. The formulation showed acceptable organoleptic properties with a yellowish-brown color, characteristic odour, sweet and slightly sour taste, pH in the range of 5.56–5.84, and viscosity between 3.2–3.4 cP. Stability studies indicated that the syrup remained stable in closed containers.(11)
