How to Make Milk Thistle Glycerite

Milk thistle is a medicinal herb that has been shown to be healing and regenerative to the liver, according to the University of Maryland Medical Center -- the seeds contain medicinal compounds. Usually the seeds are extracted into an alcohol base to make an herbal tincture, but it is possible to extract the seeds into vegetable glycerine to make an alcohol-free extract. This is known as a glycerite. The process does take time, but yields several ounces of herbal extract. Always consult with a physician before taking herbs.
