Is kava hard on your liver?

I've heard some rumors that consuming KAVA can have negative effects on the liver. Is this true? Are there any scientific studies that have confirmed or denied this claim? I'm particularly interested in knowing if there's a safe amount of kava that can be consumed without any risk to the liver. I'd also like to understand if there are any specific factors, such as pre-existing liver conditions, that could make kava consumption more dangerous. Could you please provide me with a detailed explanation of the potential risks and benefits of kava use?
