What to know

Popular "liver detox" herb. Evidence for protecting or repairing the liver in healthy people is weak; it is not a substitute for reducing alcohol or treating disease.

Interactions & cautions

  • May affect how some medications are metabolized — check interactions.

Do you actually need it?

"Detox" claims outrun the evidence. Diet and alcohol matter more.
