Claim 7:
8. A method of producing a pharmaceutical composition comprising:
providing dried pulverized powder of turmeric;
reacting the powder with an organic polar extraction solvent using percolation extraction;
acquiring a polar extract of the powder from the reacted extraction solvent;
purifying the polar extract to obtain purified curcuminoids;
mixing the purified curcuminoids with an oil phase, a co-solvent, and a surfactant in a weight ratio of 4-8:20-35:20-35:40-50 to produce the pharmaceutical composition, wherein the purified curcuminoids in the produced pharmaceutical composition has an average size of about 19 nm, wherein the purifying comprises dissolving the polar extract with a solvent mixture comprising paraffin and iso-propanol followed by filtration to generate a filtrate and crystallization of the filtrate to produce crystal having the purified curcuminoids then drying the crystal to obtain standardization 95% purified curcuminoids, wherein the purified curcuminoids comprises curcumin I, curcumin II and curcumin III in a weight ratio of 80 to 85:10 to 15:1 to 5.
