Cascara Sagrada Overview
Cascara sagrada is a tree native to the Pacific coast of North America. The name "cascara sagrada" means "sacred bark" in Spanish.
The bark of Cascara sagrada is used in traditional medicine most commonly as a laxative as it contains anthraquinone glycosides, which stimulate the muscles in the walls of the intestines, increasing peristalsis and promoting bowel movements. It is also used as a treatment for hemorrhoids and is sometimes used as a natural remedy for liver and gallbladder problems.

Ramucirumab is also used in combination with docetaxel to treat a certain type of non-small cell lung cancer (NSCLC) that has spread to other parts of the body in people who have already been treated with other chemotherapy medications and have not improved or worsened. It is also used in combination with erlotinib (Tarceva) to a certain type of NSCLC that has spread to other parts of the body. Ramucirumab is also used in combination with other chemotherapy medications to treat cancer of the colon (large intestine) or rectum that has spread to other parts of the body in people that have already been treated with other chemotherapy medications and have not improved or worsened.
