Milk thistle meal is a food supplement, not a medicine; however, the manufacturer recommends consulting a doctor before use. The following situations are particularly important to consider:
- Pregnancy and breastfeeding. The manufacturer lists these periods among the restrictions, along with individual intolerance, so the product is not taken during this time.
- Allergy to plants of the daisy family (Asteraceae, or Compositae). Milk thistle belongs to this family; people who react to ragweed, chrysanthemums or chamomile may, in theory, have a cross-sensitivity.
- Regular medication. Fibre and flavonolignans may interact with the metabolism of some medicines. If you take anything regularly, check with a doctor or pharmacist.
- Chronic conditions of the liver, biliary tract or gastrointestinal tract. With such conditions, any supplement traditionally associated with liver function requires medical supervision.
The product is not intended for children unless a paediatrician recommends otherwise. In the absence of the risk factors listed, milk thistle meal can be included in an adult's diet in the recommended serving — after the consultation with a doctor that the manufacturer advises for everyone.
