These are phenolic compounds. Plants containing anthraquinones include senna, cascara, alder buckthorn, rhubarb, yellow dock, and aloe. Excessive internal use may interfere with certain drugs, and/or cause potassium depletion and other side effects. See Aloe Herb Monograph.

ANTIVIRAL
- Anthraquinones from the following plants inactivated the Herpes I virus: Rheum officinale (rhubarb), Aloe barbadensis (aloe), Rhamnus frangula (alder buckthorn), Rhamnus purshianus (cascara buckthorn), and Cassia angustifolia (senna).
