Rhine is a relevant phytopharmaceutical with a broad pharmacological spectrum of activity. Rhine has numerous pharmacological effects such as: anti-inflammatory, anti-tumour, antioxidant, anti-fibrotic, and hepato -and nephroprotective.

Rhine has a laxative effect by stimulating the large intestine motility and by influencing the synthesis of prostaglandins, serotonin and histamine. On the other hand the drug influences several electrolyte secretion and resorption processes in the colon. The laxative effect occurs about 8-12 hours after ingestion of e.g. Senna-containing laxatives (see below Sennae folium).
