Mechanism of action

Silymarin, the active component of milk thistle (Silybum marianum), exerts hepatoprotective effects primarily through free radical scavenging and lipid peroxidation inhibition. It also modulates inflammatory pathways and may enhance liver cell regeneration. The mechanism involves stabilization of hepatocyte membranes and competitive inhibition of toxin binding to liver cells.
