Golmohammadzadeh SH et al evaluated saffron for its anti-solar activity. The pollens of the saffron (Crocus sativus) were dried and powdered in a grinder. The experimental formulations included a homosalate (8%) lotion reference, lotions with 2, 4 and 8% of grinded saffron, and the control lotion base without saffron. The lotions containing saffron were prepared like homosalate lotion reference according to FDA. The sun protection factors (SPFs) of the formulations were determined by an in vitro spectrophotometry method. The results of this study indicated that saffron can be used as a natural UV absorbing agent
