Cascara Sagrada, also known as Rhamnus purshiana, is a natural laxative derived from the bark of a tree native to North America. It has been traditionally used by indigenous people for its medicinal properties, particularly as a bowel stimulant and a remedy for constipation. Cascara Sagrada contains compounds called anthraquinones, which stimulate the muscles of the intestine to promote bowel movements. It is also believed to improve digestive health by supporting the liver, increasing bile secretion, and reducing inflammation. However, it is important to note that Cascara Sagrada should only be used under the guidance of a healthcare professional, as it can cause adverse effects if taken in excessive amounts or for prolonged periods.
