Background: Depression represents a serious public health concern, imposing a high burden, both in epidemiological and clinical terms. Crocus sativus (Saffron) is a herbal remedy that has anti-cancer, anti-oxidant, anti-inflammatory and anti-platelet properties. However, the exact mechanisms of Saffron in treating depression are not yet clear. This study was conducted to evaluate the effectiveness of Saffron versus placebo and Fluoxetine in the treatment of depressed patients. Methods: Different bibliographic thesauri, namely the Cochrane Library, Scopus, PubMed/ MEDLINE, Centre for Reviews and Dissemination (CRD), EMBASE, and ISI/Web of Science (WoS) were searched up to May 2018. Effect sizes were computed as Standardized Mean Differences (SMD) with their 95% confidence interval (CI). To evaluate the heterogeneity among the studies, I 2 test was carried out. Results: Eight studies were included. The SMD was −0.86 (95% CI: −1.73 to 0.00) concerning the comparison of Saffron with placebo. The SMD was found to be 0.11 (95% CI: −0.20 to 0.43) concerning the comparison of Saffron with Fluoxetine. In both sensitivity analyses, the results did not statistically change, confirming the stability of the findings. Conclusion: The findings of this study showed that Saffron administration was well comparable with Fluoxetine and placebo.

Background: Generalized anxiety disorder (GAD) is known as the most prevalent anxiety disorder. Saffron has been previously approved as an effective adjuvant therapy in depression and might alleviate GAD symptoms. Methods: In the current double blind randomized controlled trial, 40 patients with mild to moderate GAD, diagnosed according to the diagnostic and statistical manual of mental disorders-V (DSM-V) and received sertraline were randomly assigned to the saffron receiving group (450 mg, n = 20) or placebo taking patients (n = 20). Interventions were administered as an add-on therapy to sertraline on a daily bases for 6 weeks. In addition to assessing anthropometric, demographic data, and dietary intakes of patients, a 14-item Hamilton anxiety rating scale (HAM-A) was used to assess the effect of treatment. Results: The mean (SD) of age was 29.65 (8.45) and 32.40 (6.74) years in the Saffron and placebo groups, respectively. Applying AN-COVA models adjusted for age, baseline energy intake, HAM-A total score, and weight changes from baseline to the 6th week, showed that at the end of the 6th week, saffron treated patients had a significantly lower mean HAM-A score compared to placebo group (2.95 vs. 5.05; P value = 0.005). Furthermore, within the group analysis it was shown that the total HAM-A score significantly declined in both groups (P value ≤ 0.000). Measuring changes in the HAM-A total score, relative to the baseline, following adjustment of AN-COVA models, showed that saffron was more effective than the placebo in reducing the mean HAM-A score of patients (-17.25 ± 2.67 vs.-15.35 ± 2.30; P value = 0.029). The side effects were tolerable and did not result in discontinuation of the supplementation. Conclusions: Saffron as a sertraline add-on therapy may attenuate GAD symptoms. However, more randomized clinical trials with a larger sample size and longer duration of follow-up are needed to confirm this effect.

The morbidity and mortality associated with depression are considerable and continue to increase. Depression currently ranks fourth among the major causes of disability worldwide, after lower respiratory infections, prenatal conditions, and HIV/AIDS. Crocus sativus L. is used to treat depression. Many medicinal plants textbooks refer to this indication whereas there is no evidence-based document. Our objective was to compare the efficacy of stigmas of Crocus sativus (saffron) with imipramine in the treatment of mild to moderate depression in a 6-week pilot double-blind randomized trial.

Objective: Saffron was found efficient and safe in treatment of neuropsychiatric disorders, in particular depression. We compared the efficacy of saffron with duloxetine in treatment of patients with fibromyalgia. Materials and Methods: In this double-blind parallel-group clinical trial, outpatients with fibromyalgia were randomized to receive either saffron 15 mg or duloxetine 30 mg starting with 1 capsule per day in the first week followed by 2 capsules per day from week 2 until the end of week 8. Participants were men and women aged 18-60 years diagnosed with fibromyalgia based on the American College of Rheumatology 2010 criteria who also had a pain score≥40 based on visual analogue scale. Participants were excluded in case they had rheumatologic diseases, inflammatory/infectious/autoimmune arthritis, comorbid neuropsychiatric disorders except depressive disorders, pain due to traumatic injuries, drug history of duloxetine or saffron use, current use of psychoactive medications,...

Anxiety, stress, and low mood are closely related and may contribute to depressive symptoms. Among non-pharmacological solutions to improve subclinical mood symptoms and resilience to stress, natural products such as saffron—identified as promising following preliminary beneficial effects in major depressive disorder—represent a relevant strategy. This study aimed to assess the efficacy of 8 weeks' supplementation with 30 mg standardized saffron extract on emotional well-being in healthy adults with subclinical feelings of low mood and anxiety and/or stress and evaluate the acute effect of saffron in response to a lab-based psychosocial stressor. The study adopted a double-blind, randomized, parallel groups design in which 56 healthy male and female individuals (18–54 years) received either a saffron extract or a placebo for 8 weeks. Chronic effects of saffron on subjective anxiety, stress, and depressive feelings were assessed using a questionnaire battery [including Profile of...

Anxiety and depression have high prevalence in the general population, affecting millions of people worldwide, but there is still a need for effective and safe treatments. Nutritional supplements have recently received a lot of attention, particularly saffron. Thus, several pre-clinical studies support a beneficial role for bioactive compounds, such as saffron, in anxiety and depression. Here we used an animal model of depression based on social isolation to assess the effects of affron®, a standardized saffron extract containing ≥3.5% of total bioactive compounds safranal and crocin isomers. Affron® was administered both through the oral and the intraperitoneal routes, and several tasks related to anxiety and depression, such as the elevated plus maze, the forced swimming test or the sucrose preference test, were assessed. These tasks model key features of depressive states and anxious states relating to fear, behavioral despair or anhedonia, the lack of motivation and/or pleasure ...

Objective Saffron (Crocus sativus L.) has shown beneficial aphrodisiac effects in some animal and human studies. The aim of the present study was to assess the safety and efficacy of saffron on selective serotonin reuptake inhibitor-induced sexual dysfunction in women. Methods This was a randomized double-blind placebo-controlled study. Thirty-eight women with major depression who were stabilized on fluoxetine 40 mg/day for a minimum of 6 weeks and had experienced subjective feeling of sexual dysfunction entered the study. The patients were randomly assigned to saffron (30 mg/daily) or placebo for 4 weeks. Measurement was performed at baseline, week 2, and week 4 using the Female Sexual Function Index (FSFI). Side effects were systematically recorded. Results Thirty-four women had at least one post-baseline measurement and completed the study. Two-factor repeated measure analysis of variance showed significant effect of time  treatment interaction [Greenhouse-Geisser's corrected: F(1.580, 50.567) = 5.366, p = 0.012] and treatment for FSFI total score [F(1, 32) = 4.243, p = 0.048]. At the end of the fourth week, patients in the saffron group had experienced significantly more improvement in total FSFI (p < 0.001), arousal (p = 0.028), lubrication (p = 0.035), and pain (p = 0.016) domains of FSFI but not in desire (p = 0.196), satisfaction (p = 0.206), and orgasm (p = 0.354) domains. Frequency of side effects was similar between the two groups. Conclusions It seems saffron may safely and effectively improve some of the fluoxetine-induced sexual problems including arousal, lubrication, and pain.

Objective: A significant correlation exists between coronary artery diseases and depression. The aim of this trial was to compare the efficacy and safety of saffron versus fluoxetine in improving depressive symptoms of patients who were suffering from depression after performing percutaneous coronary intervention (PCI). Methods: In this randomized double-blind parallel-group study, 40 patients with a diagnosis of mild to moderate depression who had undergone PCI in the last six months were randomized to receive either fluoexetine (40 mg/day) or saffron (30 mg/day) capsule for six weeks. Participants were evaluated by Hamilton depression rating scale (HDRS) at weeks 3 and 6 and the adverse events were systemically recorded. Results: By the study endpoint, no significant difference was detected between two groups in reduction of HDRS scores (P¼ 0.62). Remission and response rates were not significantly different as well (P¼ 1.00 and P¼ 0.67; respectively). There was no significant difference between two groups in the frequency of adverse events during this trial.

Saffron (Crocus sativus L.) is a medicinal plant, originally cultivated in the East and Middle East, and later in some Mediterranean countries. Saffron is obtained from the stigmas of the plant. Currently, the use of saffron is undergoing a revival. The medicinal virtues of saffron, its culinary use and its high added value have led to the clarification of its phytochemical profile and its biological and therapeutic characteristics. Saffron is rich in carotenoids and terpenes. The major products of saffron are crocins and crocetin (carotenoids) deriving from zeaxanthin, pirocrocin and safranal, which give it its taste and aroma, respectively. Saffron and its major compounds have powerful antioxidant and anti-inflammatory properties in vitro and in vivo. Anti-tumor properties have also been described. The goal of this review is to present the beneficial effects of saffron and its main constituent molecules on neuropsychiatric diseases (depression, anxiety and schizophrenia) as well a...
