The Effects of Aloe Vera Cream on the Alar Scar in Rhinoplasty, A Randomized Double-Blind Controlled Trial.

Introduction: Many studies have been done on the use of aloe vera in wound healing, but fewer studies were done on the influence of this material on the reduction of the alar scar. Therefore, we evaluated the effect of a newly made aloe vera cream on alar wound healing after rhinoplasty. Materials and Methods: This was a randomized, double-arm, parallel-group, double-blind controlled trial and was done from June 2021 to February 2022. External wedge resection was done for all patients. The patients were randomly assigned to receive aloe vera cream (n=31) (intervention group) or Face Doux cream (comparison group) (n = 29). A pharmacist prepared the aloe vera cream. The primary outcome measure was the wound scar status which was assessed by two Questionnaires, including the mean Patient Scar Assessment Questionnaire (PSAQ) and Vancouver Scar Scale (VSS). Randomization and Blinding were done. Results: The mean PSAQ was significantly lower in group A after two weeks (26.9 versus 31.5, P<0.001), after two months (15.7 versus 19.6, P=0.04), and six months follow-up (8.8 versus 11.8, P=0.005). The mean VSS was significantly lower in group A after two weeks (5.6 versus 7.1, P=0.001), after two months (3.5 versus 4.9, P=0.002), and six months (1.2 versus 2.7, P<0.001). Repeated measurement analysis showed that both interventions significantly affected PSAQ and VSS. Conclusion: Although both interventions had a significant effect on PSAQ and VSS, compared to Face Duox, the topical use of Aloe Vera cream significantly reduced scar formation after alar resection, both statistically and clinically.

Safety and efficacy of a polyherbal formulation from traditional Persian medicine in patients with calcium kidney stones: A randomized, double-blinded clinical trial.

Background: 10%-15% of the world's population suffers from kidney stones. Nearly 50% increase was observed in diagnosing and treating nephrolithiasis in the last decades. Effective medical treatment for the disease is not yet well established. Moreover, there is an increasing global demand to manage diseases using complementary and alternative medicine. This study aimed to formulate and assess the safety and efficacy of a multi-ingredient formulation from traditional Persian medicine (TPM) known as Mofatet powder in patients suffering from calcium kidney stones. Materials and Methods: The aqueous extract of Mofatet powder was prepared, freeze-dried, and formulated as capsules. 26 patients in the drug group and 25 patients in the placebo group used 500 mg capsules of the drug/placebo twice daily for 5 weeks. Ultrasonography/kidney, ureter and bladder imaging, urine analysis, and biochemical parameters were evaluated before and after the intervention. Results: The imaging results showed a 60.73% decrease (P < 0.001) in stone size in the drug group. Moreover, the urinary calcium decreased (P = 0.02) and the urinary magnesium increased (P < 0.001) in the drug group. No remarkable changes were observed in the placebo group in these parameters. No significant effect was observed in aspartate transaminase, alanine transaminase, serum creatinine, and blood urea nitrogen levels in none of the groups. Conclusion: This study suggests that Mofatet powder was effective in reducing calcium kidney stones size with no potential nephro/hepatotoxicity. After confirming these results in larger clinical trials with longer duration, this formulation can be considered a treatment for nephrolithiasis.

Efficacy of castor oil cream in treating infraorbital hyperpigmentation: An exploratory single-arm clinical trial.

INTRODUCTION: Infraorbital hyperpigmentation represents one of the most prevalent conditions in cosmetic dermatology. To treat this condition, many patients prefer natural remedies. This study explored the efficacy of topical castor oil cream in treating patients with infraorbital hyperpigmentation. METHODS: We conducted an exploratory single-arm clinical trial at the Shahid Faghihi Dermatology Clinic and Molecular Dermatology Research Center of Shiraz University of Medical Sciences, Shiraz, Iran, during 2021-2022. Using the convenience sampling method, we enrolled 25 patients with infraorbital hyperpigmentation. We instructed the patients to apply topical castor oil cream twice daily for 2 months. The darkness, melanin, and erythema levels were evaluated by VisioFace® 1000 D and SkinColorCatch® devices. We used a visual analog scale to assess skin laxity, wrinkles, and patient satisfaction. Data analysis was done with Stata version 14.2. RESULTS: The data of 22 patients with a mean age of 40.92 ± 7.33 years were analyzed. The VisioFace® scores decreased significantly by the end of the study [right eyes: mean difference (MD): -5.63 (95% CI: -7.12 to -4.15), p < 0.001; left eyes: MD: -5.91 (95% CI: -7.46 to -4.36), p < 0.001]. Moreover, castor oil cream significantly reduced the melanin level, wrinkles, and skin laxity in the infraorbital region (p < 0.05). CONCLUSIONS: Castor oil cream seems to be an effective alternative for treating infraorbital hyperpigmentation. Randomized clinical trials are needed to confirm our findings.

The efficacy of Allium ampeloprasum L. in reducing neutrophil recovery time in childhood cancer with febrile neutropenia: a randomized, double-blind, placebo-controlled trial.

INTRODUCTION: Febrile neutropenia is a serious complication of cancer chemotherapy that can result in delays in treatment. This study evaluates the efficacy of A. ampeloprasum L. at neutrophil recovery time in children with chemotherapy-associated febrile neutropenia. METHODS: This single-center, parallel-group, double-blind, randomized clinical trial was conducted at an oncology hospital. Patients selected among childhood cancers with febrile neutropenia. Overall, 97 febrile neutropenic children were enrolled. The intervention group (n=49) was given A. ampeloprasum L. in capsules (500 mg twice daily) for seven days plus supportive care. The control group (n=48) was treated similarly with supportive care and placebo capsules. Total white blood cell (WBC) and absolute neutrophil counts (ANC) were checked daily and neutrophil recovery time in both groups was compared. RESULTS: Patients in the intervention group experienced shorter neutrophil recovery compared to the control group (4.02 ± 2.32 days vs. 6.38 ± 2.80 days, respectively, P less than 0.001). The intervention group was discharged from the hospital earlier than the control group with a mean of two days, but it did not reach statistical significance (P=0.133). Mean WBC and ANC were not significantly different in the two groups. Herbal medicine was well tolerated, and no adverse effect was reported. CONCLUSIONS: A fresh, lyophilized extract from deciduous leaves of A. ampeloprasum L. can effectively shorten the ANC recovery time leading to an earlier release from the hospital. The trial was registered in the Iranian Registry of Clinical Trials with registration No. IRCT2015051615666N2 (http://www.irct.ir/).

Topical Licorice for Aphthous: A Systematic Review of Clinical Trials.

Background: Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease that affects oral mucosa. The coating agents, topical analgesics, and topical steroids are usually used as treatment methods. Glycyrrhiza glabra has been used for RAS treatment based on its anti-inflammatory, antioxidant, and immunomodulatory properties. In this study, a systemic review on the therapeutic effect of topical licorice on RAS management was performed. Methods: Science Direct, Scopus, Cochrane databases, PubMed Google Scholar, and ResearchGate were searched up to September 2021 to find all English randomized clinical trials studying the effect of G. glabra, or its compositions on RAS. Meta-analysis was not conducted because of data heterogeneity. Articles were reviewed qualitatively, and only those with a Jadad score ≥3 were included. Animal studies, in vitro, review papers, non-English papers, and case reports were excluded. Results: Six studies with 314 subjects were included after screening. The result showed licorice has significant effects on RAS pain reduction, ulcer size, and healing time. Its effectiveness is related to its dose-dependent anti-inflammatory and antioxidant effects through several mechanisms. It also has antibacterial effects against Streptococci mutans and Porphyromonas gingivalis as another mechanism of action in RAS treatment. In addition, licorice can elevate the epidermal growth factor (EGF) level compared to the control group, which has an essential role in oral mucosal tissue integrity. Conclusion: Licorice extract has been used in different dosage forms, including paste, patch, and mouthwash with concentrations of 1% or 5%. The healing time after licorice therapy is expected to be within 4-8 days. Licorice did not show any adverse effect in the intervention groups, indicating its effectiveness and safety in RAS treatment.

An Overview of Pharmacological and Clinical Aspects of Spirulina.

Spirulina or Arthrospira, a Cyanobacterium from the class Cyanophyceae, with a wide range of properties, has been applied for over 400 years. The present study aimed to review available investigations surrounding the clinical and pharmacological properties of Spirulina that have been carried out so far. Databases including Scopus, PubMed, Google Scholar, and Web of Science were searched for relevant literature using the keywords: (Spirulina), (pharmacology), and (clinical). About 130 papers that studied the pharmacological characteristics of Spirulina in animal models, as well as clinical trials, were selected from the beginning to 29 July 2021. According to this review, antioxidative, anti-inflammatory, anti-neoplastic, hypolipidemic, antiviral, immunomodulatory, antimicrobial, anti-atherogenic, anti-diabetic, and radio-protective functions are attributed to Spirulina. Moreover, Spirulina's positive influence on several organs, including hair, skin, liver, CNS, lung, and genitourinary tract, are ascribed to different components of various species of Spirulina such as Spirulina platensis, Spirulina fusiformis, and Spirulina maxima. Although so many studies have been accomplished on every aspect of Spirulina in recent years, the lack of a comprehensive investigation surrounding this microalga encouraged us to prepare this paper. Therefore, the present study could be considered an up-to-date overview of the clinical, pharmacological, and molecular aspects of Spirulina, resulting in more occupational research on this valuable organism.

Evaluation of metabolites in Iranian Licorice accessions under salinity stress and Azotobacter sp. inoculation.

Licorice (Glycyrrhiza glabra L.) is an industrial medicinal plant that is potentially threatened by extinction. In this study, the effects of salinity (0 and 200 mM sodium chloride (NaCl)) and Azotobacter inoculation were evaluated on 16 licorice accessions. The results showed that salinity significantly reduced the fresh and dry biomass (FW and DW, respectively) of roots, compared to plants of the control group (a decrease of 15.92% and 17.26%, respectively). As a result of bacterial inoculation, the total sugar content of roots increased by 21.56% when salinity was applied, but increased by 14.01% without salinity. Salinity stress increased the content of glycyrrhizic acid (GA), phenols, and flavonoids in licorice roots by 104.6%, 117.2%, and 56.3%, respectively. Integrated bacterial inoculation and salt stress significantly increased the GA content in the accessions. Bajgah and Sepidan accessions had the highest GA contents (96.26 and 83.17 mg/g DW, respectively), while Eghlid accession had the lowest (41.98 mg/g DW). With the bacterial application, the maximum amounts of glabridin were obtained in Kashmar and Kermanshah accessions (2.04 and 1.98 mg/g DW, respectively). Bajgah and Kashmar accessions had higher amounts of rutin in their aerial parts (6.11 and 9.48 mg/g DW, respectively) when their roots were uninoculated. In conclusion, these results can assist in selecting promising licorice accessions for cultivation in harsh environments.

Startup-Based Learning as an Innovative Method for Pharmacy Education: Medicinal Plants Course Model.

Background: Familiarizing students with knowledge-based businesses is one of the goals emphasized in the developed educational systems worldwide. This study aimed to design a startup-based learning model (SBL). Methods: As a qualitative research study, startup teams were formed by the pharmacy students of Shiraz University of Medical Sciences in 2020. This model was used to train 120 students as pharmaceutical entrepreneurs through related lectures, simulations, and field activities. We employed this model for students to become familiar with the various stages of examining market needs, knowledge-based company registration, intellectual property, logo design, and even pharmaceutical product development. Students' feedback was assessed with a questionnaire designed by the team of researchers, and its results were used to analyze the course and improve the quality of the proposed model. Results: Most of the studied indices revealed that the students rated this model as good or excellent. Satisfaction with more important indices includes student creativity and ideation in educational activity (60.7%), attractive presentation (60.4%), teamwork among learners (62.2%), appropriateness of evaluation method (65.4%), understanding how to make herbal remedies (49.1%), learner participation in the educational activity (74.8%), entrepreneurial motivation (60.7%), and applicability (64.4%). Conclusion: We found this model effective in boosting students' satisfaction, creativity, and entrepreneurial spirit. Lecturers also play a facilitator role in addition to specialized training. Therefore, in this model, both lecturers and students can grow more and make education more attractive. This study, for the first time, demonstrated that SBL could be applied in education systems and make the students more interested in educational content and help them to prepare for the job market.

Efficacy of Ginger Supplementation in Relieving Persistent Hypothyroid Symptoms in Patients with Controlled Primary Hypothyroidism: A Pilot Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

Primary hypothyroidism is a common disease. Some patients have persistent symptoms despite normal serum thyroid-stimulating hormone (TSH) levels. Ginger is reported to be beneficial in relieving similar symptoms. Our aim was to evaluate the efficacy of ginger supplementation in relieving persistent symptoms in these patients. In this randomized, double-blind, placebo-controlled clinical trial, 60 hypothyroid patients aged 20-60 years with normal serum TSH concentrations were randomly allocated to two equal parallel study groups of ginger (500 mg twice a day) or placebo for 30 days. Hypothyroid symptoms were evaluated as the primary outcome using the Thyroid Symptom Rating Questionnaire (ThySRQ) before and after the intervention. Anthropometric measures and laboratory indices including TSH, triglyceride (TG), total cholesterol (TChol), and fasting blood sugar (FBS) were considered as secondary outcomes. A significant lower mean total ThySRQ score (8.63 ± 5.47 vs. 15.76 ± 6.09, P < 0.001) was observed in the ginger group compared to the control group. Ginger led to significant improvements in the mean scores of the weight gain, cold intolerance, constipation, dry skin, appetite, memory loss, concentration disturbance, and feeling giddy or dizzy domains (P < 0.001). However, no significant improvements were observed in hair loss, nail fragility, hearing, hoarseness, speech, and depression or feeling down (P > 0.05). Ginger supplementation also led to a significant decrease in body weight, body mass index, waist circumference, serum TSH, FBS, TG, and TChol levels compared to the placebo. In summary according to preliminary results of this study, ginger supplementation can help relieve persistent hypothyroid symptoms. Also, it may have beneficial effects in terms of weight reduction and regulation of the FBS and lipid profile in hypothyroid patients.

Cardiovascular implications of the COVID-19: Management of complications and drug safety concerns.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, has rapidly spread worldwide and has been infected more than 219 million individuals with 4.55 million deaths worldwide as of September 2021, causing a pandemic. Preexisting cardiovascular (CV) comorbidities such as hypertension, diabetes, and coronary artery disease seem to be associated with greater severity of infection, worse prognosis, and higher mortality. Moreover, COVID-19 can contribute to CV complications, including acute myocardial injury, arrhythmia, acute coronary syndrome, and venous thromboembolism, emphasizing the importance of precocious detection and implementation of optimal therapeutic strategies. This review provides an overview of evidence-based data of CV complications of COVID-19, focusing on their management strategies, as well as potential cardiac adverse effects and drug interactions, due to off-label and investigational drugs used for the treatment of COVID-19.

Antibacterial Activity of Prunus Scoparia Root Methanol Extract against Most Common Burn Wound Pathogens.

BACKGROUND: Burn wound infection and sepsis are serious medical conditions requiring prompt intervention. Plants are a good natural source for the development of novel, safe, and cost-effective antibacterial agents. The objective of the present study was to assess the antibacterial potential of aqueous, chloroform, and methanol extracts of the Prunus scoparia (P. scoparia) root against the most common burn wound pathogens. METHODS: The present experimental study was conducted at Shiraz University of Medical Sciences (Shiraz, Iran) during 2018-2019. The antibacterial activity of the total plant extract was assayed using the broth microdilution method. Fractionation was performed using a separation funnel and solvents with different polarities. Broth microdilution and agar well diffusion assays were performed to determine the antibacterial potential of the obtained fractions. Quantitative and qualitative phytochemical analyses were performed to confirm the presence of secondary metabolites in both the total extract and the fractions. RESULTS: Methanolic extract of P. scoparia root exhibited antibacterial activity against all tested bacterial strains, especially against Methicillin-resistant Staphylococcus aureus (MRSA) isolates. This extract, compared to the aqueous and chloroformic extracts, exhibited the presence of active antibacterial compounds. The quantitative and qualitative results of phytochemical screening showed that phenols and flavonoids were the main antibacterial compounds in the methanolic extract of the plant. CONCLUSION: For the first time, we demonstrated the antibacterial activity of the P. scoparia root against MRSA isolates and other common burn wound pathogens.

Efficacy of cinnamon in patients with type II diabetes mellitus: A randomized controlled clinical trial.

BACKGROUND & AIMS: Multiple studies have evaluated the hypoglycemic effect of cinnamon in patients with diabetes mellitus (DM) type II, with conflicting results. Differences in Baseline Body Mass Index (BMI) of patients may be able to explain the observed differences in the results. This study was designed to evaluate the effect of cinnamon supplementation on anthropometric, glycemic and lipid outcomes of patients with DM type II based on their baseline BMI. METHODS: The study was designed as a triple-blind placebo-controlled randomized clinical trial, using a parallel design. One hundred and forty patients referred to Diabetes Clinic of Yazd University of Medical Sciences with diagnosis of DM type II were randomly assigned in four groups: cinnamon (BMI ≥ 27, BMI < 27) and Placebo (BMI ≥ 27, BMI < 27). Patients received cinnamon bark powder or placebo in 500 mg capsules twice daily for 3 months. Anthropometric, glycemic and lipid outcomes were measured before and after the intervention. RESULT: Cinnamon supplementation led to improvement of all anthropometric (BMI, body fat, and visceral fat), glycemic (FPG, 2hpp, HbA1C, Fasting Insulin, and Insulin Resistance), and lipids (Cholesterol Total, LDL-c and HDL-c) outcomes (except for triglycerides level). All observed changes (except for Cholesterol Total and LDL-c) were significantly more prominent in patients with higher baseline BMI (BMI ≥ 27). CONCLUSION: Based on the study findings, cinnamon may improve anthropometric parameters, glycemic indices and lipid profile of patients with type II diabetes. These benefits are significantly more prominent in patients with higher baseline BMI (BMI ≥ 27). The trial protocol was registered in Iranian Registry of Clinical Trials database (registration ID: IRCT2017031133015N1).

The effects of Zataria multiflora Boiss. (Shirazi thyme) on nonalcoholic fatty liver disease and insulin resistance: A randomized double-blind placebo-controlled clinical trial.

OBJECTIVE: The aim of the study is to evaluate the effects of Zataria multiflora Boiss. (Shirazi thyme) (ZM) supplementation on nonalcoholic fatty liver disease (NAFLD) and related insulin resistance (IR). DESIGN: In this randomized double-blind placebo-controlled clinical trial, 85 patients with NAFLD were administered either 700 mg ZM powder or placebo twice daily for 12 weeks. All patients were advised to follow the recommendations for diet modification. RESULTS: ZM supplementation resulted in a significant reduction in serum insulin level (-2.72 ± 0.80 vs -0.67 ± 0.90, P=0.030), insulin resistance (-0.80 ± 0.22 vs 0.06 ± 0.22, P=0.023), systolic (-3.44 ± 1.05 vs 1.03 ± 0.98, P= 0.002) and diastolic (-2.33 ± 0.77 vs 0.26 ± 0.63, P= 0.009) blood pressure in patients with NAFLD in comparison with the placebo group. There was no significant difference between two groups regarding serum levels of alanine aminotransferase (ALT), high sensitive C-reactive protein (hs-CRP), Tumor necrosis factor-α (TNF-α), grade of fatty liver in ultrasonography, lipid profiles, and other outcomes. CONCLUSION: ZM supplementation with daily dose of 1400 mg for 12 weeks improved insulin resistance in patients with NAFLD. Further studies with longer duration and larger sample size are recommended.

Anorexia: Highlights in Traditional Persian medicine and conventional medicine.

OBJECTIVE: Anorexia and impaired appetite (Dysorexia) are common symptoms with varying causes, and often need no serious medical intervention. Anorexia nervosa (AN) is a chronic psychiatric disease with a high mortality rate. In Traditional Persian Medicine (TPM), anorexia is a condition in which anorexic patients lose appetite due to dystemperament. This review aims to discuss the common points of traditional and conventional approaches rather than introducing Persian medical recommendations suitable for nowadays use. MATERIALS AND METHODS: For this purpose, Avicenna's Canon of Medicine, main TPM resources and important databases were reviewed using the related keywords. RESULTS: Despite complex hormonal explanation, etiology of AN in conventional approach is not completely understood. In TPM approach, the etiology and recommended interventions are thoroughly defined based on humoral pathophysiology. In TPM approach, disease states are regarded as the result of imbalances in organs' temperament and humors. In anorexia with simple dystemperament, the physician should attempt to balance the temperament using foods and medicaments which have opposite quality of temperament. Lifestyle, spiritual diseases (neuro - psychological) and gastrointestinal worms are the other causes for reducing appetite. Also, medicines and foods with warm temperaments (such as Pea soup and Mustard) are useful for these patients (cold temperament). CONCLUSION: Although the pathophysiology of AN in TPM is different in comparison with conventional views, TPM criteria for treatment this disorder is similar to those of current medicine. Recommending to have spiritual support and a healthy lifestyle are common in both views. Simple safe interventions recommended by TPM may be considered as alternative medical modalities after being confirmed by well-designed clinical trials.

Insulin resistance improvement by cinnamon powder in polycystic ovary syndrome: A randomized double-blind placebo controlled clinical trial.

Our aim is to assess the effect of cinnamon powder capsules on insulin resistance, anthropometric measurements, glucose and lipid profiles, and androgens of women with polycystic ovarian syndrome (PCOS). Out of 80 women that were diagnosed as PCOS by Rotterdam Criteria, 66 were enrolled in this randomized double-blind placebo-controlled clinical trial. All of the PCOS women were taking medroxy progesterone acetate 10 mg/day for the last 10 days of their menstrual cycles. The cases were randomly allocated to 2 groups. The women in the first group were treated by cinnamon powder capsules 1.5 g/day in 3 divided doses for 12 weeks and the second group by similar placebo capsules. Anthropometric measurements, fasting blood sugar, fasting insulin, blood glucose 2 hr after taking 75 g oral glucose, HbA1c, testosterone, dehydroepiandrosterone sulphate, homeostatic model assessment for insulin resistance, triglyceride, and cholesterol (low-density lipoprotein, high-density lipoprotein, and total) before and after the intervention were evaluated and compared as outcome measures. Fasting insulin (p = .024) and homeostatic model assessment for insulin resistance (p = .014) were reduced after 12 weeks in the cinnamon group compared with the placebo. There was also a significant decrease in low-density lipoprotein in cinnamon group (p = .004) as compared with baseline that caused significant difference with placebo (p = .049). However, changes in other outcome measurements did not lead to statistically significant difference with placebo. The present results suggest that complementary supplementation of cinnamon significantly reduced fasting insulin and insulin resistance in women with PCOS.

Efficacy of cryotherapy plus topical Juniperus excelsa M. Bieb cream versus cryotherapy plus placebo in the treatment of Old World cutaneous leishmaniasis: A triple-blind randomized controlled clinical trial.

BACKGROUND: Cutaneous leishmaniasis is one of the highly prevalent endemic diseases in the Middle East and North Africa. Many treatment modalities have been recommended for this condition but success rates remain limited. Herbal remedies have also been used for treatment but evidence-based clinical trials with these products are sparse. In-vitro and in-vivo studies have shown the anti-leishmanial and curative effects of extract of fruits and leaves of Juniperus excelsa (J. excelsa). The aim of this study was to determine the efficacy of topical J. excelsa M. Bieb extract as an adjuvant to cryotherapy for the treatment of human CL. MATERIALS AND METHODS: This study was designed as a two-arm triple-blind randomized placebo-controlled clinical trial using a parallel design. Seventy-two patients with clinical diagnosis of CL confirmed by leishmania smears were allocated to receive either a topical formulation of leaf of J. excelsa extract (group A) or placebo (group B) for 3 months. Both groups received cryotherapy as baseline standard treatment. Patients were evaluated before and weekly after the intervention was initiated until complete cure. RESULTS: Overall, 82% of patients in group A, experienced complete cure and 9% of them had partial cure. On the other hand, 34% in group B reported complete cure, while 14% of them had partial cure at the end of treatment protocol with a significant difference between the two groups (P< 0.001). The mean duration to healing of the lesions in patients who received J. excelsa extract was statistically significantly shorter than the placebo group (p = 0.04). No significant side effect was seen in the J. excelsa extract group except for mild to moderate local irritation after a few weeks in a few numbers of patients. CONCLUSION: The results of this study showed that topical J. excelsa extract can be used as an adjuvant treatment modality in addition to cryotherapy for accelerating the time to cure in addition to increasing the complete cure rate in CL.

An Evidence-Based Review on Medicinal Value of Clays in Traditional Persian Medicine.

The use of earths and clays for medical purposes dates back to antiquity. In recent years, there has been an increasing interest in researches on traditional remedies in the hope of discovering new drug. Iran is an ancient country with a medical backbone acquired from the experiences of ancient Persian scholars, who had made a great contribution to the development of the medical sciences. Many medical and pharmaceutical books by early Persian scientists still exist and may have the potential of leading researchers to new drug discoveries. Owing to the emergence of new and antimicrobial-resistant infections, present-day medicine has recently begun focusing on medicinal earths and clays especially as mineral antimicrobials. The current study is, therefore, aimed at gathering information regarding medicinal clays in traditional Persian medicine (TPM). Five main Persian materia medica with the key word 'tin' (clay) and current databases such as PubMed, Scopus, ScienceDirect, and Google Scholar were searched by key words 'white, green, red, maroon, violet, black, grey and pink clays' and 'pharmacological effects'. Twenty three clays were found in Persian manuscripts. Although their mineralogical compositions are unknown, different pharmacological properties have been attributed to these mineral medicaments. Clay's properties were widely used in medieval times for the treatment of infections to poisoning. They were also used in compound formulations, possibly for their pharmaceutical formulation modifying effects. Modern scientific proofs have also been found in many of the medicinal clays reported in Persian manuscripts. Although many of the reported clays are still unknown, their characterization may lead to new medicinal developments. Novel analytical methods available today make it possible to elucidate the chemical compositions of these minerals as parameters responsible for their medicinal effects.

The Effect of Traditional Treatments on Heavy Metal Toxicity of Armenian Bole.

BACKGROUND: Clay has been used for its nutrition, cosmetic, and antibacterial properties for thousands of years. Its small particle size, large surface area, and high concentration of ions have made it an interesting subject for pharmaceutical research. There have been studies on scavenging foreign substances and antibacterial properties of clay minerals. The main problem with the medical use of these agents, today, is their heavy metal toxicity. This includes arsenic, cadmium, lead, nickel, zinc, and iron. Iranian traditional medicine (ITM) introduces different clays as medicaments. In this system, there are specific processes for these agents, which might reduce the chance of heavy metal toxicity. Armenian bole is a type of clay that has been used to treat a wound. Before in vivo studies of this clay, its safety should be confirmed. METHODS: In this work, we investigated the effect of washing process as mentioned in ITM books regarding the presence of Pb, As, and Cd in 5 samples using atomic absorption spectrometry. We washed each sample (50 g) with 500 cc of distilled water. The samples were filtered and dried at room temperature for 24 hours. RESULTS: In all studied samples, the amount of Pb and Cd was reduced after the ITM washing process. The amount of As was reduced in 3 samples and increased in 2 other samples. CONCLUSION: In ITM books, there are general considerations for the use of medicinal clay. These agents should not be used before special treatments such as the washing process. In this study, we observed the effect of washing process on reducing the amount of heavy metals in Armenian bole samples. In two samples, washing caused an increase in the amount of As. As these heavy metals sediment according to their density in different layers, the sample layer on which the spectrometry is performed could have an effect on the results.

Ethnopharmacological knowledge of Shiraz and Fasa in Fars region of Iran for diabetes mellitus.

ETHNOPHARMACOLOGICAL RELEVANCE: This study provides ethnopharmacological knowledge of traditional herbal healers from Shiraz and Fasa in Fars region (Iran) for treatment of diabetes mellitus. MATERIALS AND METHODS: Field surveys were carried out during September 2013-February 2014 in Shiraz and Fasa. The data were collected through structured questionnaire in Persian. All plant species recorded for the treatment of diabetes mellitus were sampled. Samples were identified by a botanist and obtained a voucher specimens number and deposited in the Shiraz School of Pharmacy Herbarium. The information such as scientific name, family, local name, medicinal use(s), parts used and preparation method were provided. Literature review on available data about antidiabetic effect of the addressed plant species was done to highlight gaps in current knowledge and propose the next steps.
