It is not easy to use the exact plant origin recorded in the literature since natural raw materials show inconsistent quality or ingredient content depending on the cultivation time and method. If research is conducted using non-standardized materials, the reliability and reproducibility of the research results will inevitably be low. Reproducible results can be obtained only when research is conducted using materials with clear origin plant, production area information, extraction method, and ingredient content.
