Cathartica

Cathartica is a term of Latin origin used in science to describe purgative properties. It is not a standalone organism or chemical, but a descriptive form that appears in different contexts. In taxonomy, cathartica commonly serves as a species epithet in the scientific names of plants and other organisms, signaling that the material or organism was historically associated with purgative or cleansing effects. The epithet does not by itself certify safety or efficacy, and many uses reflect historical or ethnobotanical knowledge rather than current medical practice.

In medicine, the related adjective cathartic designates agents that induce defecation and accelerate intestinal transit. Cathartics are a stronger category of laxatives and include stimulant, osmotic, and irritant compounds. Because of risks such as dehydration, electrolyte disturbances, and potential interactions with other medicines, cathartics are typically used under medical supervision and only for specific indications. They are contraindicated in conditions like bowel obstruction or active inflammatory disease unless advised by a clinician.

Outside pharmacology, the term also appears in linguistic and cultural discussions in the sense of cleansing or purification, reflecting the broader etymology from Greek katharsis.
