1. A method of treating methicillin-resistant S. aureus infection, comprising administering to a patient in need thereof an effective dose of gold nanoparticles capped with Caralluma sinaica extract, the gold nanoparticles capped with Caralluma sinaica extract made according to a method comprising the steps of:

adding an extract of Caralluma sinaica to an aqueous HAuCl₄solution to reduce the HAuCl₄and form a suspension of gold nanoparticles capped with the extract of Caralluma sinaica;

removing an unreacted portion of the extract of Caralluma sinaica from the suspension; and

collecting the gold nanoparticles capped with the extract of Caralluma sinaica from the suspension.
