Abstract

Heavy metal contamination of traditional herbal medicine (jamu) is a threat to humans, especially at levels above known threshold concentrations. Traditional herbal medicine found in Banda Aceh City – Indonesia, polluted by heavy metals cadmium (Cd), lead (Pb), and mercury (Hg) was performed. Heavy metal analysis used Flame - Atomic Absorption Spectrometry (FAAS) and Chemical Vapor Generation - Atomic Absorption Spectrometry (CVG - AAS) methods. The validation of the method was performed to obtain more accurate heavy metal analysis results for the samples. Heavy metal contamination, especially Pb metal, with concentrations of 4.32 ± 0.14 mg/Kg to 29.25 ± 0.24 mg/Kg. The Cd metal contamination was only found in herbal medicine sample E with a concentration of 0.80 ± 0.02 mg/Kg, above the threshold. The Hg metal contamination was also found with concentrations of 0.20 ± 0.01 to 2.14 ± 0.06 mg/Kg, and some were not detected. The government should be very concerned about stopping the distribution of herbal medicine that can be harmful to health and should inspect drug stores that still sell herbs that do not have established standards.

Abstract

Curry leaves (Bergera koenigii) are widely recognized for their rich phytochemical content and antioxidant properties; however, their application as active ingredients in cosmetic delivery systems remains relatively underexplored. This study aimed to evaluate the phytochemical profile and antioxidant activity of the ethanol extract of B. koenigii leaves and to investigate its potential incorporation into a peel-off mask formulation through physicochemical characterization. Antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay, while formulation quality was evaluated through organoleptic properties, homogeneity, pH, viscosity, spreadability, drying time, stability testing for 28 days, cycling test, and skin irritation assessment. Phytochemical screening confirmed the presence of tannins, flavonoids, steroids, and saponins. The ethanol extract exhibited very strong antioxidant activity with an  value of 8.23 µg/mL, indicating a high free radical scavenging capacity. The formulated peel-off masks demonstrated stable physicochemical properties during storage, with viscosity values of 6,740–13,729 cPs, spreadability of 5.3–6.6 cm, drying time of 14.03–16.36 minutes, and pH values within the acceptable skin-compatible range (6.40–6.63). No irritation responses were observed in the preliminary skin test. These findings highlight the potential of B. koenigii ethanol extract as a promising natural antioxidant ingredient for peel-off mask cosmetic formulations.
