Milk Thistle Seed Oil is cold pressed from the seeds of the Milk Thistle Plant (Silybum Marianum), which we commonly see throughout the land in the summer months. Milk Thistle Seed Oil is an excellent source of silymarin, a complex of bioactive compounds. It is unrefined, i.e., unsaturated, which means that as many valuable ingredients as possible are retained. Milk Thistle Seed Oil is cold-pressed, as many of the compounds contained in the oil are temperature-sensitive, so the richness of the substances given by nature is preserved and enriched with vitamin E.
