“Herbal medicines are plant-based medicines made from differing combinations of plant parts eg. leaves and flowers or solely the roots. Each part can have different medicinal uses and the many types of chemical constituents require different extraction methods. Both fresh and dried plant matter are used, depending on the herb.
I am aware of the importance of medicines being sourced from reputable manufacturers who maintain consistent quality standards. Traceability (right back to the original batch of herbs) and certificates of authenticity are key ways in which quality is maintained. Sustainability is also of crucial importance.”
