Answer by Dr. Ru: About St Mary´s Thistle usage in lactation

Milk thistle is a herb from which its fruits are used. It contains flavonolignans, silymarin and especially silibinin isomers, silychristin and silydianin, flavonoids, steroids and estrogen-like compounds. Attributed properties: Liver Protector.Indications based on the Commission E of the German Ministry of Health: cholelithiasis, liver disorders. Devoid of toxicity. It is excreted into breast milk in little or no amount.There is no evidence of its effectiveness as a galactogogue. Two studies have been performed (one with cows and the other with women) trying to show a galactogogue effect, but both are limited by a very flawed methodology.Best galactogogue is a frequent and on-demand breastfeeding together witn an appropriate technique. Precaution is recommended before taking herbal infusions:1. Ensure a reliable source: poisoning occurred by confusion with another plant that resulted to be toxic, poisoning from heavy metals and food poisoning by contamination with bacteria or fungi.2. Avoid excessive consumption. The "natural" products are not good in any amount: plants contain active substances from which come out much of our traditional pharmacopoeia and can cause poisoning if eaten in exaggerated quantity or prolonged time.
