We praise the article by Mokhtari-Zaer et al. (2015) published in the Avicenna Journal of Phytomedicine on the effects of saffron on smooth muscle activity (Mokhtari-Zaer et al., 2015). It was a well-designed and interesting study on the therapeutic properties of <em>Crocus sativus</em> which is a precious plant cultivated in our country. We do believe that along with all other medicinal effects, saffron or its active constituents, primarily crocin and crocetin, could also have some clinical implications in the gynecology field. Historically and particularly in traditional Persian medicine, saffron has been regarded as an abortifacient agent (Hosseinzadeh and Nassiri-Asl, 2013; Schmidt et al., 2007). Farmer women exposed to saffron had increased rates of miscarriage (Ajam et al., 2014). This could be due to the fact that saffron stimulates uterine contractions. However, in Table 1 of the article by Mokhtari-Zaer et al. (2015), a relaxant effect of saffron on uterine contraction was mentioned (Mokhtari-Zaer et al., 2015). Concerning various components of saffron including crocin, picrocrocin, crocetin, and safranal, each could have different actions on muscular tissue. As an antispasmodic, saffron is used for stomach pain by helping digestion and improving appetite. It also reduces tension and alleviates symptoms of premenstrual syndrome and renal colic (Agha-Hosseini et al., 2008; Moshiri et al., 2006; Kashani et al., 2018). In one study, the impact of saffron on cervical ripening in term pregnant women was evaluated for the first time in the form of a clinical trial (Sadi et al., 2016). They concluded that saffron could induce cervical priming which is a perquisite for vaginal delivery by improving the bishop score. Cervical ripening caused by prostaglandins such as misoprostol or prostaglandin E1 is associated with simultaneous increase in uterine muscle contractility which is apparently in contrast with the effects of saffron as a relaxing agent (Vahdat et al., 2015). In a study by Sadraei et al, the effects of <em>Crocus sativus</em> extracts on uterus contractions were assessed in vitro. Following removal of the uteri of rats, spontaneous rhythmic contractions were induced using potassium chloride (KCL). According to their results, <em>Crocus sativus</em> increased these contractions and showed spasmodic action on muscle fibers (Sadraei et al., 2003). Likewise, in other studies, saffron had stimulatory effects on uterus as a result of myogenic and neurogenic actions resulting in prolonged bleeding, premature birth and abortion (Tafazoli et al., 2004; Modaghegh et al., 2008). This stimulatory effect of saffron on uterine musculature, however, is sometimes desirable in obstetrics to enhance the process of labor and also in gynecology for facilitating the surgical procedures on the uterus (Sadi et al., 2016; Vahdat et al., 2015). Thus, the exact mechanism of action of saffron derivatives on uterus and cervix has not been fully elucidated yet. In all the studies mentioned, the effects of the plant extract were assessed without purifying or differentiating its different elements which could have different or even opposing actions. With the availability of saffron tablets in Iran which mainly consists of crocin, with the brand name of Krocina, we believe that it would be much easier to assess the impact of this particular component of saffron on uterine or cervical tissue to clarify the exact mechanisms underlying abortion or induction of labor.<br /> In the end, we congratulate Mokhtari-Zaer et al on their article and we appreciate the Avicenna Journal of Phytomedicine editorial board for their judicious concern on this topic. We hope to read well-controlled randomized clinical trials regarding the beneficiary effects of saffron in future

Objective: This study was conducted to assess the toxicity profile of the aqueous-fermented extract of Musa paradisiaca in rats.<br /> Materials and Methods: In acute toxicity test, the rats of different groups were orally administered with a single dose of 500, 1000, 2000 and 5000 mg/kg of fermented extract of M. paradisiaca. The rats were monitored for behavioral changes, toxicity signs and mortality. In sub-acute test, the rats were orally administered with fermented M. paradisiaca extract (200, 400 and 800 mg/kg/day) for 14 days. Haematological and serum biochemical parameters were evaluated and histopathological studies of the liver and kidney were done. The study was performed from June to July 2017.<br /> Results: Concerning the acute toxicity, no toxicity signs or death were recorded and an LD<sub>50 </sub>value of >5 g/kg for fermented extract of M. paradisiaca was observed. Regarding the sub-acute toxicity, ingestion of the fermented extract of M. paradisiacacaused no significant effects (p<0.05) in terms of relative organ weight, body weight percentage, haemoglobin, red blood cells count, electrolytes levels, lymphocytes count, basophils count, and aspartate aminotransferase (AST) and alkaline phosphatase (ALP) levels. However, significant differences (p<0.05) were observed in white blood cells, eosinophils, platelets, neutrophils and monocytes counts, and urea, creatinine, alanine aminotransferase (ALT) and high-density lipoprotein (HDL) levels. The histological assessments of the liver and kidney showed normal results.<br /> Conclusion: The findings of this study has suggested that daily administration of fermented extract of M. paradisiaca at doses up to 800 mg/kg for 14 days, is not toxic and may be considered safe for therapeutic uses.

Objective: The present study was designed to investigate the protective effects of hydroalcoholic extract of Rheum turkestanicum against HgCl<sub>2</sub> hepatorenal toxicity in rats.<br /> Materials and Methods: Animals were randomly divided into five groups (n= 6 in each group) and received HgCl<sub>2</sub> and plant’s extract, intraperitoneally. Group1 received saline (1 mL/kg/day), group 2 received extract (200 mg/kg/day), group 3 was treated with HgCl<sub>2</sub> (5 mg/kg/day,) and groups 4 and 5 received the extract (100 and 200 mg/kg/day, respectively), 1 hr before HgCl<sub>2</sub> administration. All injections last for 3 days. Blood samples and specimens of the liver and kidney were collected 24 hr after the last injection.<br /> Results: Data showed that HgCl<sub>2</sub> significantly increases liver malondialdehyde (MDA) level, reduces total sulfhydryl content and increases serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity, compared to control group. The histopathological changes such as inflammatory cells infiltration was observed in HgCl<sub>2</sub>-treated group while plant’s extract partially improved histological changes. The extract (100 and 200 mg/kg/day) improved the liver functions as reflected by significant reductions in AST and ALT levels in serum, MDA decreased and the content of total sulfhydryl elevated. Also, the extract improved necrosis and atrophy of the kidney induced byHgCl<sub>2</sub>. Pretreatment with the extract reduced creatinine and urea in serum, and glucose and protein concentrations in urine, compared to HgCl<sub>2</sub>- treated group (group III). The extract significantly reversed HgCl<sub>2</sub>-induced depletion in thiol content and elevation in MDA content.<br /> Conclusion: Therefore, oxidative stress may play an important role in HgCl<sub>2</sub>-induced hepatorenal injury and R. turkestanicum extract may be regarded as a useful to protect the kidney and liver against HgCl<sub>2</sub>-induced oxidative damage.

<strong>Objective:</strong> 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.<br /> <strong>Materials and Methods:</strong> 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, recent use of muscle relaxants, steroids, opioid analgesics, benzodiazepines, anti-epileptics, or injective analgesics. Primary outcomes included differences in mean score changes from baseline to endpoint between the treatment arms for Hamilton Rating Scale for Depression, Fibromyalgia Impact Questionnaire, and Brief Pain Inventory.<br /> <strong>Results:</strong> Socio-demographic characteristics and baseline scores were similarly distributed between the two treatment arms (2n=46). No significant difference was detected for any of the scales neither in terms of score changes from baseline to endpoint between the two treatment arms (Mean score changes: -4.26 to 2.37; p-values: 0.182-0.900) nor in terms of time´treatment interactions (p-values: 0.209-0.964).<br /> <strong>Conclusions:</strong> Saffron and duloxetine demonstrated comparable efficacy in treatment of fibromyalgia symptoms.

<strong><span style="font-size: medium;">Objective:</span></strong><span style="font-size: medium;"> <em>Cassia fistula</em></span><span style="font-size: medium;"> L. fruit extract has been traditionally used in the treatment of pemphigus vulgaris (PV) lesions in Iran. The aim of this study was to determine the efficacy of </span><em><span style="font-size: medium;">C. fistula</span></em><span style="font-size: medium;"> fruit gel on healing time of PV lesions in a clinical setting.<br /></span><strong><span style="font-size: medium;">Materials and Methods:</span></strong><span style="font-size: medium;"> This was a randomized, double-blind placebo-controlled clinical trial that was performed in dermatology ward at Saadi hospital, affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. Right- or left- sided lesions of PV patients on standard systemic treatment were randomized for treatment with either </span><em><span style="font-size: medium;">C. fistula</span></em><span style="font-size: medium;"> fruit gel or placebo prescribed twice daily. The largest diameter of each lesion was measured at the baseline (day 0) and on days 10 and 20. Epithelialization Index (EI), as outcome measure was calculated and compared between the two groups.<br /></span><strong><span style="font-size: medium;">Results:</span></strong><span style="font-size: medium;"> The present study comprised 20 patients, with overall 82 cutaneous lesions including 41 lesions in the </span><em><span style="font-size: medium;">C. fistula</span></em><span style="font-size: medium;"> fruit gel group and 41 lesions in the placebo group. The EI in the </span><em><span style="font-size: medium;">C. fistula</span></em><span style="font-size: medium;"> fruit gel group was significantly higher than that of the placebo group both on day 10 (65±28vs 30±34; p=0.001) and at the end of the study (91±22 vs 69±49; p=0.003). <br /></span><strong><span style="font-size: medium;">Conclusion:</span></strong><span style="font-size: medium;"> Topical application of </span><em><span style="font-size: medium;">C. fistula</span></em><span style="font-size: medium;"> fruit gel can be considered as an effective adjuvant therapy in treatment of PV.</span>
