Milk thistle is known for strong hepatoprotective and antioxidant actions. Its active constituents, the silymarin complex, help protect liver cells by stabilizing cell membranes, promoting protein synthesis for regeneration, boosting glutathione levels, and scavenging free radicals. This combination reduces lipid peroxidation and supports liver recovery after toxin or drug exposure.

Because milk thistle comes from the Asteraceae family, it can trigger allergic reactions in people with Asteraceae sensitivity, so it is contraindicated in that group. Other herbs in the list may offer antioxidant effects or some liver-supportive activity, but they don’t match both the clear hepatoprotective/antioxidant profile and the Asteraceae allergy contraindication as directly as milk thistle.
