Saint Mary’s Thistle (S. marianum)
Liver Health and Immune Modulation
Has a stimulatory and restorative effect on the liver, removes free-radicals, and toxic peroxides products. Silybin helps reduce enzymatic hyperactivity and hyperlipidemia in the liver. [1,2] Silybin has also been found to accelerate liver regeneration via stimulation of hepatocytes. [3,4] Extracts did not show any restorative capabilities in subjects with liver cirrhosis but did show liver protection capabilities when given in conjunction with alcohol. [5] Immunomodulant activities were regarded as similar to that of echinacea. [6]
Lactation
Increases in breastmilk is usually conducted in studies using isolated compounds or analogues of compounds found in saint Mary’s thistle (SMT). The results are mixed, with some papers reporting little-no change in breast milk production, while others find significant differences between control and “active” groups. [7,8,9,10] One thing of note is that while the results are mixed in terms of total milk volume day to day, a few studies have shown that the treatment group often breastfed their babies more, for longer. While also having less issues while doing so. [5,11]
Toxicity
Classed as low toxicity, with one study showing no toxicity at doses of 10,000 mg/kg [12] No embryotoxicity was observed. [13] No detectable transfer of thistle compounds into breast milk. [14] 5g mixture of thistle and goats rue showed no side effects in breastfed infants. [15]
