Flavokavain A is a flavokavain found in the kava plant.^[1] It induces apoptosis in bladder cancer cells via a Bax protein-dependent and mitochondria-dependent apoptotic pathway.^[2]

Flavokavains A and B enhance hepatotoxicity of paracetamol, underscoring a potentially serious interaction between paracetamol and kava.
