Reversible Worsening of Parkinson Disease Motor Symptoms After Oral Intake of Uncaria Tomentosa (Cat's Claw)

Carlos Cosentino et al. Clin Neuropharmacol. .

Abstract

Uncaria tomentosa (UT), also known as cat's claw, isa Peruvian Rubiaceae species widely used in traditional medicine for the treatment of a wide range of health problems. There is no report about the use, safety, and efficacy of UT in neurological disorders. We describe reversible worsening of motor signs in a patient with Parkinson disease after oral intake of UT, and some possible explanations are discussed.
