喝酒前先吃颗护肝片就能护住肝
真相
没有补剂被证明能抵消乙醇的肝损伤，酒精性肝病里水飞蓟对死亡率与并发症都无显著效果；把它当许可证只会让真正起作用的那件事——少喝——被推迟。

水飞蓟本身不太会伤肝。美国国立卫生研究院的药物性肝损伤数据库（LiverTox）把它引起肝损伤的可能性评为 E 级：不太可能引起临床上看得到的肝损伤，也没有被记录到会让转氨酶升高（LiverTox 2020）。口服最常见的不适是腹胀、恶心、排气多和稀便。它是菊科植物，对豚草、菊花、万寿菊、雏菊过敏的人可能交叉过敏（NCCIH）。

Human trials in chronic liver disease have been 'promising but inconclusive'; milk thistle itself has not been implicated in serum enzyme elevations or clinically apparent liver injury (likelihood score E); intravenous purified silybinin is approved in Europe for Amanita phalloides poisoning.

Trial results for liver disease have been 'conflicting or too limited to allow conclusions'; two NCCIH-funded trials (hepatitis C and nonalcoholic steatohepatitis) showed no benefit. Allergic reactions can occur in people allergic to ragweed, chrysanthemum, marigold, and daisy.
