Quality Control

Our Rhamnus Frangula Extract is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure identity, purity, and consistency, with specifications potentially aligned to relevant pharmacopoeial standards (e.g., USP, Ph. Eur.) for botanical extracts. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metals, residual solvents, and microbiological limits is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and maintain product integrity.
