Herb used for treating liver conditions.

• A. Milk thistle
• B. Bladderwrack
• C. Echinacea purpurea
• D. Goldenseal

Answer: (A)

Milk thistle is known for its hepatoprotective effects. The active component silymarin helps stabilize liver cell membranes, acts as an antioxidant to reduce free-radical damage, and supports hepatocyte regeneration. This combination makes it a commonly used herb for liver conditions, including chronic liver disease and toxin-related liver injury, in supportive care. The other herbs listed have different primary uses: bladderwrack is valued mainly for iodine content and thyroid-related concerns; echinacea purpurea is used to support immune function; goldenseal is used for antimicrobial purposes. Therefore, milk thistle best aligns with liver treatment.
