Calcium hydroxide nanoparticles synthesized with carob pulp extract

A pharmaceutical composition comprising:

• calcium hydroxide nanoparticles and a pharmaceutically acceptable carrier, wherein the calcium hydroxide nanoparticles are synthesized by:
• (a) heating ethylene glycol, wherein heating the ethylene glycol is performed in an ultrasonic water bath heated to a temperature of about 99.9° C.;
• (b) adding calcium hydroxide to the ethylene glycol to form a first mixture;
• (c) heating the first mixture, wherein heating the first mixture is performed in an ultrasonic water bath heated to a temperature of about 99.9° C.;
• (d) adding a carob pulp aqueous extract to the first mixture to form a second mixture;
• (e) heating the second mixture wherein heating the second mixture is performed in an ultrasonic water bath heated to a temperature of about 99.9° C.;
• (f) adding sodium hydroxide to the second mixture to form a third mixture;
• (g) heating the third mixture wherein heating the third mixture is performed in an ultrasonic water bath heated to a temperature of about 99.9° C.;
• (h) resting the third mixture after heating;
• (i) centrifuging the third mixture and collecting a colloid sediment, wherein the centrifuging is at 1500 rpm for 30 minutes and repeated a plurality of times;
• (j) extracting chemical contaminants from the colloid sediment to provide a purified colloid sediment;
• and
• (k) drying the purified colloid sediment to obtain the Ca(OH)2 nanoparticles, wherein the nanoparticles have a minimum diameter of 31.22 nm and a maximum diameter of 81.22 nm.
