4. What Happens When Milk Thistle Goes Bad?
When expired or improperly stored, milk thistle may lose potency or develop harmful by-products:
Silymarin degradation: Reduced antioxidant activity (source: Journal of Pharmacy and Pharmacology, 2014)
Rancid oils: Cold-pressed oil oxidizes, forming aldehydes and ketones, which are cytotoxic.
Mycotoxin risk: Moisture exposure may lead to mold growth, especially Aspergillus flavus, which can produce aflatoxins, known liver carcinogens.
💡 According to a 2021 study in Food Control, improperly stored milk thistle seeds showed a 3.4% contamination rate with detectable aflatoxins in humid conditions above 65% RH.
