Milk Thistle

A liver-positioned botanical where silymarin standardization, medication context, and diagnosis-aware expectations matter more than detox marketing.

Practical read

Do not use milk thistle as a substitute for evaluating liver symptoms or abnormal labs. If a clinician clears it, keep the extract and dose consistent so effects and tolerability are easier to interpret.
