Results-  Saffron at a dose of 10 mg/kg significantly increased renal blood flow with minimum tissue side effects, while at the higher doses it was remarkably associated with tissue lesions such as ATN and glomerulopathy. Conclusion and Clinical Relevance- Saffron is a scarce and valuable crop because of the stigma’s charming fragrance and pleasant flavor, the aroma of which is naturally furnished by a desirable golden color when dried. Due to innate therapeutic properties, it has been a focus of interest for modern pharmacological studies to comprehensively recognize the advantages of using saffron, in the light of its low toxicity and powerful anti-oxidant properties. Beyond direct effects on the epithelial cell function, saffron significantly enhances vascular blood flow, resulting in an indirect control towards cardiovascular system. In conclusion, saffron therapy is recommended in ischemic conditions. The preferred doses ranged between 10 to 40 mg/kg. At the dose of 10 mg/kg lower tissue side effects is expected.}, keywords = {Saffron,Kidney,Doppler ultrasonography,Pathology,Blood flow}, url = {https://www.ivsajournals.com/article_3214.html}, eprint = {https://www.ivsajournals.com/article_3214_a5e9fffa9d6aa1bd66856e2ca9733399.pdf} }
