Scientific Summary

Milk Thistle is the flowering plant *Silybum marianum*, cultivated for its bright yellow flower heads and bitter orange‑green fruits. It is used primarily as a liver tonic to support liver health and detoxification, especially in conditions such as hepatitis and liver injury. It is generally well tolerated, but high doses or prolonged use can cause mild gastrointestinal upset; people taking anticoagulants or other liver‑metabolized drugs should consult a healthcare professional.
