Reversible worsening of Parkinson disease motor symptoms after oral intake of Uncaria tomentosa (cat's claw).
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.
