Why was kava banned in Germany?

Could you elaborate on the reasons behind the ban of kava in Germany? I'm curious to understand the specific regulatory concerns or health risks that may have prompted this decision. As a professional practitioner in the field of cryptocurrency and finance, I'm always interested in how different jurisdictions approach the regulation of digital assets and their potential implications for investors and the market. Is there any precedent for this ban in other countries? And what are the potential consequences for the kava community and its ecosystem?
