Blessed Thistle is a plant that can be used medicinally. During the Middle Ages, it was used to treat the Bubonic Plague and as a tonic for monks. Over time, it has been discovered to be able to treat many ailments including colds, loss of appetite and indigestion, fevers, bacterial infections, and diarrhea when made into a tea. It is also a diuretic and helps increase urine output. In modern times, Blessed Thistle has been used as an herbal remedy to increase milk supply for breastfeeding mothers.  It is often used together with Fenugreek when being used as a breast milk stimulant. Its active ingredients that help it work are called tannins. A tannin is an astringent that binds to proteins and other organic compounds like amino acids and alkaloids. These tannins may help diarrhea, coughs, and inflammation, however more research needs to be done to see how effective they are.

Although Blessed Thistle and Fenugreek are herbal supplements, they aren’t without risks. Pregnant and breastfeeding women should always seek advice from their doctors before taking any supplements. If taken in high doses, Blessed Thistle may cause stomach irritation and vomiting. Liver disease, gastrointestinal and liver problems, and esophageal or nasal cancer have been reported when it is taken in excessive amounts. If taken orally, it can cause irritation to the gastrointestinal tract. The recommended dosage of Blessed Thistle is 3-4 capsules taken three times a day. It is also available in liquid form and the dosage is 10-20 drops or 2mL for three times a day. For infusions, the dosage is 1.5-2g in 150ml of water taken orally three times a day. For tea, 1.5-3g of dried Blessed Thistle boiled in 150ml of water for 10-15min can be taken three times daily.
