Is kava bad for your liver?

Could you elaborate on the potential risks of kava to the liver? I've heard some conflicting opinions regarding its safety, and I'm interested in understanding the scientific evidence behind its potential harm. Could you provide a concise but comprehensive overview of the studies that have been conducted, highlighting any significant findings or conclusions? Additionally, are there any specific groups of individuals, such as those with existing liver conditions, who should avoid consuming kava altogether? Thank you for your time and attention to this matter.
