The document provides guidelines for regulating herbal medicines in Europe and Japan. In Europe, herbal medicinal products are regulated and must comply with guidelines on quality control, safety, efficacy, advertising and more. Herbal medicines from foreign countries entering the market must also provide proof of quality, safety and efficacy. In Japan, traditional herbal medicines called Kampo are regulated similarly to conventional drugs, and must undergo clinical trials and comply with good manufacturing practices. Japan also has various systems for monitoring adverse reactions to herbal medicines. The regulatory frameworks aim to standardize quality while allowing traditional herbal approaches to be practiced legally.
