However，curcumin is difficult to dissolve in water，and low bioavailability limits the development prospect of curcumin in clinical use. It can be compensated by changing the administration mode and dosage form of curcumin. Currently，curcumin can prepare lipids. Dosages such as body，nanoparticle，microspheres，micelles，and microemulsions are administered in different ways to improve their hydrophilicity and improve bioavailability.
