In order to inhibit the growth of fungi, such as Madurella mycetomatis, gold nanoparticles are synthesized and capped with an extract of Reseda arabica. The gold nanoparticles capped with the extract of Reseda arabica are made by adding the extract of Reseda arabica to an aqueous sodium tetrachloroaurate (NaAuCl.sub.4) solution to reduce the sodium tetrachloroaurate and form a suspension of gold nanoparticles capped with the extract of Reseda arabica. The extract of Reseda arabica acts as a reducing and stabilizing agent while also functionalizing the surfaces of the gold nanoparticles to cap the surfaces. The suspension may be boiled, followed by removal of the gold nanoparticles capped with the extract of Reseda arabica from the suspension. To treat a Madurella mycetomatis infection, an effective dose of the gold nanoparticles capped with Reseda arabica extract may be administered to a patient in need thereof.
