Introduction: Costus pictus belong to Zingiberaceae family, in Cuba is known as caña mexicana and decoction of leaves and fresh stems is traditionally used for urinary disorders like infections, lithiasis and renal colic. The aim of this work was to identify the main groups of secondary metabolites and to validate pharmacology and toxicology properties of a decoction of fresh leaves and stems from C. pictus. Methods: Airs fresh parts were collected and conducted a farmacognostic and pharmacology study. A phytochemical screening identified the main groups of secondary metabolites present in the decoction 30%. Analgesic activity was determinate by contortions induced by acid acetic (0.75% via i.p) and removal of the tail submerged into water at 55°C. Anti-inflammatory activity was assay in cotton-induced granulomas in rats and relaxations of smooth musculature in urethra. Toxicology test were CTA and toxicity in repeat doses. Results: Main secondary metabolites were phenol, tannins, and flavonoids. Decoction of C. pictus inhibits contractions of the urethra induced by KCl. The toxicology study not presents nor intoxications, nor death. It significantly reduced the painful response both models, but there was no anti-inflammatory effect on cotton-induced granuloma. Conclusions: The results contributed to validate the traditional use of C. pictus fresh leaves and stems in order to relieve the pain caused by renal diseases.
