BackgroundCarthamus tinctorius L., known as Kafesheh (Persian) and safflower (English) is vastly utilized in Traditional Medicine for various medical conditions, namely dysmenorrhea, amenorrhea, postpartum abdominal pain and mass, trauma and pain of joints. It is largely used for flavoring and coloring purposes among the local population. Recent reviews have addressed the uses of the plant in various ethnomedical systems.ObjectiveThis review was an update to provide a summary on the botanical features, uses in Iranian folklore and modern medical applications of safflower.MethodsA main database containing important early published texts written in Persian, together with electronic papers was established on ethnopharmacology and modern pharmacology of C. tinctorius. Literature review was performed on the years from 1937 to 2016 in Web of Science, PubMed, Scientific Information Database, Google Scholar, and Scopus for the terms “Kafesheh”, “safflower”, “Carthamus tinctorius”, and so forth.ResultsSafflower is an indispensable element of Iranian folklore medicine, with a variety of applications due to laxative effects. Also, it was recommended as treatment for rheumatism and paralysis, vitiligo and black spots, psoriasis, mouth ulcers, phlegm humor, poisoning, numb limbs, melancholy humor, and the like. According to the modern pharmacological and clinical examinations, safflower provides promising opportunities for the amelioration of myocardial ischemia, coagulation, thrombosis, inflammation, toxicity, cancer, and so forth. However, there have been some reports on its undesirable effects on male and female fertility. Most of these beneficial therapeutic effects were correlated to hydroxysafflor yellow A.ConclusionMore attention should be drawn to the lack of a thorough phytochemical investigation. The potential implications of safflower based on Persian traditional medicine, such as the treatment of rheumatism and paralysis, vitiligo and black spots, psoriasis, mouth ulcers, phlegm humor, poisoning, numb limbs, and melancholy humor warrant further consideration.

Ethnopharmacological relevance: The genus Curcuma, which is the most important source of curcumin, has been widely used in different traditional medicines. Various species of Curcuma have long been used for several purposes such as healing wounds, liver disorders, jaundice and also as a blood purifier. Aim of the study: This review focused on the ethnopharmacological uses and phytochemical aspects of Curcuma. Additionally, in this study, the different properties of two species of Curcuma in Islamic Traditional Medicine (ITM), C. longa and C. zedoaria, as well as their pharmacological aspects in modern medicine are reviewed. Materials and methods: ITM literatures were searched to find Curcuma’s applications. Also, electronic databases including PubMed and Scopus were searched to obtain studies giving any in vitro, in vivo or human evidence of the efficacy of C. longa and C. zedoaria in the treatment of different diseases. ChemOffice software was used to find chemical structures. Results: The analysis showed that ethno-medical uses of Curcuma have been recorded for centuries. Approximately, 427 chemical compounds have been isolated and identified from Curcuma spp. This genus is rich in flavonoids, tannins, anthocyanin, phenolic compounds, oil, organic acids and inorganic compounds. Curcumin is one of the main active ingredients in Curcuma which has strong anti-inflammatory and antioxidant effects. Besides, pharmacological studies have indicated wide range of Curcuma’s activities, such as hepato-protective, antifungal, antihypertensive and neuroprotective. Conclusions: In this study, we reviewed various studies conducted on ethno-medicinal, ITM properties and photochemistry of Curcuma spp. Also, pharmacological activities of two species, C. longa and C. zedoaria are summarized. Pre-clinical investigations have demonstrated some of the traditional aspects of Curcuma, such as wound healing, anti-arthritic, anti-tumor and liver protective activities. These could be related to antioxidant and anti-inflammatory properties of Curcuma which might be due to high amounts of phenolic compounds. Curcuma is mentioned to have neural tonic properties in ITM which have been confirmed by some animal studies. Considering various preclinical studies on C. longa and C. zedoaria and their active ingredient, curcumin, randomized controlled trials are warranted to confirm their promise as a clinically effective hepato and neuro-protective agents.

Background: The fruit of genus Rosa, known as "rose hip", is frequently used in different traditional medicines. Rose hips have long been used to treat kidney stones, gastroenteric ailments, hypertension and respiratory problems such as bronchitis, cough and cold. Aim: This review is focused on the ethnopharmacological uses of rose hip as well as phytochemical and pharmacological aspects. Results: Ethno-medical uses of rose hip have been recorded in many countries since a long time. Approximately, 129 chemical compounds have been isolated and identified from rose hip. This fruit contains some major active components such as flavonoids, tannins, anthocyanin, phenolic compounds, fatty oil, organic acids and inorganic compounds. Scientific studies have suggested a wide range of pharmacological activities for rose hip including antioxidant, anti-inflammatory, anti-obesity, anti-cancer, hepatoprotective, nephroprotective, cardioprotective, antiaging, anti H. pylori, neuroprotective and antinociceptive activities. In particular, the rose hip powder and extract have been reported to exert therapeutic effects on arthritis. Conclusion: Some of the ethnomedical indications of rose hip, such as nephroprotective and gastroproetctive actions, have been confirmed by preclinical pharmacological studies. Additional investigations on the pharmacological effects of rose hip as well as evidence from randomized controlled trials are essential to assess the therapeutic value of this natural product.
