Abstract
The jungles of Central and South America contain two predominant species of cat’s claw (Uña de Gato), Uncaria tomentosa (Willd. ex Schult.) DC. and Uncaria guianensis (Aubl.) J.F. Gmell, which are used in traditional medicine mainly for their anti-inflammatory properties. However, a wealth of compounds have been isolated from these two vines of the Rubiaceae family, including alkaloids, flavonoids and terpenoids, showing a wide range of activities: anti-inflammatory, anti-oxidative, hypotensor, antiviral, smooth muscle relaxant, antispasmodic, gastrointestinal mucosa protector, antiarrhythmic, anticonvulsant, analgesic, anti-leishmaniosis, cytostatic, cytotoxic, hypoglycaemizing, anticholestatic, antihistaminic, hepatoprotective, diuretic, antiulcer, immunostimulating and sedative effects. Some of these activities have been confirmed in both in vitro and in vivo models.
