1. Copper oxide nanoparticles, the copper oxide nanoparticles resulting from the method comprising the steps of:
a) adding boiled water to Rumex vesicarius material to produce a liquid extract;
b) filtering the extract to produce a filtered liquid extract;
c) dissolving a copper salt in the filtered liquid extract to produce a solution with copper nanoparticles;
d) adding a base to the solution with copper nanoparticles to form a precipitate;
e) removing liquid from the precipitate to provide a pellet;
f) drying the pellet, to produce a powder including the copper oxide nanoparticles.
