Razi’s Al-Hawi and saffron (Crocus sativus): a review

-

Traditional knowledge can be used as a source for development of new medicines. In the present study, we compare the data on saffron in Raziʹs Al-Hawi book with modern scientific studies. A computerized search of published articles was performed using MEDLINE, Scopus as well as native references. The search terms used were saffron, Crocus sativus, crocetin, crocin, safranal, Razi, and Al-Hawi. A variety of properties of saffron including diuretic, analgesic, anti-inflammatory, hepatoprotective, appetite suppressant, hypnotic, antidepressant, and bronchodilator effects were mentioned in Al-Hawi. Modern studies also confirmed most of these characteristics. This review indicates that the pharmacological data on saffron and its constituents are similar to those found in Razi’s Al-Hawi monograph and it can be concluded that ethnobotanical information and ancient sources have precious data about medicinal plants that lead to finding new compounds for treatment of several diseases.
