RESUMO

Sweet almond (Prunus dulcis (Mill.) D.A.Webb) is a known nut, which has long been used in several ethnomedical systems, especially in Persian medicine (PM) for its nutritional and therapeutic activities. In this study, we aimed to provide a summary on traditional uses, phytochemistry, and pharmacological activities of sweet almond. Thus, we reviewed textbooks of PM and electronic literature on traditional medicine. Moreover, the available data on the usage of sweet almond were searched in electronic databases to find articles on its pharmacological properties and phytochemistry. According to phytochemical investigations, this plant contains macronutrients, micronutrients, essential oils, various phenolic compounds, and phytosterols. Current pharmacological studies represent that Prunus dulcis has several biological activities including prebiotic, antimicrobial, antioxidant, antiinflammatory, anticancer, hepatoprotective, cardiometabolic protection, nootropic, anxiolytic, sedative-hypnotic, and nervous-improving effects. Further clinical trials and meta-analysis are required to draw a definitive conclusion on the efficacy and therapeutic activities of almond.

RESUMO

This trial was performed to compare quince (Cydonia oblonga) fruit with vitamin B6 on 76 pregnant women with a gestational age of 6-14 weeks and mild-to-moderate nausea and vomiting (NVP) (40 in the quince and 36 in the B6 group). The 'Pregnancy-Unique Quantification of Emesis' (PUQE-24) scale was used to examine the severity of NVP. The quince syrup (1 tablespoon/TDS) or vitamin B6 tablets (20 mg/TDS) were used as intervention for 1 week. The mean (±SD) age was 27.5 (±5.2) years. The score of the PUQE was decreased from 9.5 (± 2) at baseline to 5.2 (±2.3) on the 7th day and 5.3 (±2.6) on the 14th day (p < .001) in the quince group. In the other group, the scores were 8.4 (±1.8), 7.3 (±2.4) and 7.7 (±3.8), respectively (p = .001). The change in symptoms were more marked in the quince group (p < .001). Quince syrup seems to be a suitable treatment for NVP. Impact statement What is already known on this subject: Pregnancy-induced nausea and vomiting (NVP) is one of the most common problems during gestation. Treatment is mainly symptomatic, ranging from dietary changes and oral pharmacological treatment to hospitalization in severe forms. In early pregnancy, the use of chemical drugs is avoided, so there is an increasing tendency to use alternative therapies. According to the literature review in Iranian Traditional Medicine (ITM), the quince fruit (Cydonia oblonga) can be useful in NVP. Quince has a wide range of pharmacological activities including antioxidant, antibacterial, antifungal, anti-inflammatory, hepatoprotective and antidepressant effects. ITM literature suggests some therapeutic effects of the quince fruit on important organs like brain, heart, liver and stomach. What the results of this study add: The results of this study demonstrated the significant efficacy of quince in comparison with vitamin B6. What the implications are of these findings for clinical practice and/or further research: This fruit is also safe to be administered in pregnant women suffering from NVP.

RESUMO

Terminalia chebula (family: Combretaceae) is widely used in the traditional medicine of India and Iran to treat diseases that include dementia, constipation, and diabetes. This tree is known in Iranian traditional medicine (ITM) as halileh or halilaj and the fruit is used to develop treatments. It is described in ITM as an astringent that has a "cold" and "dry" temperament. References to the medicinal properties of Terminalia chebula were collected from important ITM sources and from modern medical databases (PubMed, Scirus, ScienceDirect, and Scopus). The medicinal properties described for this tree in ITM were compared with those reported in studies of modern phytotherapy. The results confirm that the tree referred to as halileh in traditional books is the Terminalia chebula used in present-day studies. Treatments that have not been evaluated in modern phytotherapy but have been traditionally treated with Terminalia chebula include fever, and psychological and psychiatric issues. This article confirms the medicinal uses of Terminalia chebula.

RESUMO

Background: Basil is a widely used herb in Persian medicine and is gaining recognition as a functional food worldwide. Aim of the study: This trial aimed to assess the effectiveness of a traditional formulation of basil oil in comparison with diclofenac gel in treating knee osteoarthritis, considering its established anti-inflammatory, anti-nociceptive, and anti-oxidative properties. Materials and methods: One hundred eligible patients were equally randomized to the traditional basil oil (containing sesame oil) and diclofenac gel groups. They used their respective topical treatments thrice daily for 4 weeks. Various measurements were taken at the beginning of the study, 2, and 4 weeks after starting the intervention, including the 8-m walk test, knee pain (based on visual analog scale), flexion angle of the knee joint, analgesic consumption, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Results: No significant differences were observed between the basil oil and diclofenac gel groups in any of the measured outcomes. However, significant improvements were noted within each group for most variables. Conclusion: Topical application of the traditional formulation of basil oil appears to improve clinical symptoms and certain functional indicators of knee osteoarthritis to a similar extent as diclofenac gel. This suggests that basil oil could be considered an effective management option for this condition. Clinical Trial Registration: https://irct.behdasht.gov.ir/, identifier IRCT2017081711341N7.

RESUMO

BACKGROUND: Although there are various therapeutic options to control oily skin, they have potential side effects and limitations especially in long-term use. Pre/probiotics may have beneficial effects in atopic dermatitis' acne, dandruff, and seborrhea, demonstrated by some clinical trials. This trial conducted to determine whether the herbal prebiotic Triphala is effective in reducing scalp sebum secretion in patients with scalp seborrhea. METHODS: In this 8 week patient and outcome assessor-blinded, placebo-controlled trial participants with scalp seborrhea aged 14-50 years were randomized to Triphala or placebo groups. 1 g of Triphala (standardized as 91.82 ± 0.5 mg gallic acid) or placebo (wheat flour) were administered BID. Scalp sebum levels were detected objectively using Sebumeter® sm 815, and treatment satisfaction was measured using a score between 0 and 100. [Registration no. IRCT2014070218332N1]. RESULTS: Eighty patients completed the study (40 in Triphala group and 40 in placebo group). Participants in the Triphala group experienced 25.34 scores (95% CI, 0.39-50.29: p = .047) more improvement in scalp sebum levels compared with the placebo group. The mean percentage of patients' satisfaction was 37.91 (24.88) in the Triphala group and 17.89 (25.80) in the placebo group (p = .001). CONCLUSION: Herbal prebiotic Triphala significantly reduced scalp sebum scores compared to placebo.

RESUMO

OBJECTIVE: Golnar product is a poly herbal formulation advised by Persian medicine to control heavy menstrual bleeding (HMB). This study was conducted to compare the efficacy of this product with placebo in patients with HMB. MATERIALS AND METHODS: In this double-blind randomized clinical trial, 100 women with HMB were randomly assigned into two groups. The patients in the Golnar group (n=50) took Golnar capsules 500 mg three times a day for the first 7 days of menstrual cycle for three cycles. The placebo group (n=50), took placebo capsules in the same manner. The duration and volume of bleeding (using Pictorial Blood Loss Assessment Chart: PBAC), quality of life (using Menorrhagia Questionnaire: MQ), and hemoglobin level (Hb) were measured 3 months after initiation of the intervention. RESULTS: Eighty-two patients (43 in the Golnar and 39 in the placebo groups) completed the 3-month intervention period. In the Golnar group, PBAC score decreased from 201.62 (144.11) to 109.44 (69.57) (p<0.001) and MQ score improved significantly from 0.58 (0.27) to 0.39 (0.31) (p<0.001), while changes in placebo group were not significant. Hb increased in the Golnar group from 12.78±0.98 to 12.97±0.95 mg/dl (p=0.048) and decreased in the placebo group from 12.94±1.08 to 12.44±1.01mg/dl (p<0.001). No significant adverse effects were found in the Golnar group. CONCLUSION: The Golnar product can be considered an effective intervention for patients with HMB. Assessment of side-effects is suggested to be performed in a larger sample. In addition, a comparison between the Golnar product and nonsteroidal anti-inflammatory drugs could be valuable.

RESUMO

Objective: To investigate the effect of the Carum carvi (Bunium persicum Boiss) plant, a gas solvent, on resumption of bowel motility after caesarean section. Materials and methods: A randomized controlled trial was done on a group of 98 women undergoing elective caesarean section under general anesthesia in a university hospital. Patients in the intervention group (Group A) drank 10 ml of a syrup containing 8 g of Bunium persicum Boiss in 20 ml of syrup 6 to 7 hours after surgery. The control group (Group B) comprised 10 patients who drank 10 ml of placebo syrup 6 to 7 hours after surgery. Demographic characteristics, time to first hearing of normal intestinal sounds, time to first flatus, time to first bowel movement, and length of hospital stay were compared between the two groups. Results: Compared with the control group, the intervention group had a significantly shorter mean time to hearing the first intestinal sounds (10.66 ± 2.38 vs. 19.54 ± 3.85 h), mean time to first flatus (13.91 ± 3.73 vs. 24.82 ± 5.83 h), mean time to first bowel movement (19.31 ± 4.63 vs. 30.70 ± 10.21 h), and mean length of hospitalization (31.70 ± 7.70 vs. 49.20 ± 10.16 h) (p < 0.05). No patients developed serious side effects associated with consumption of the syrup. Conclusion: The use of a gas solvent such as Bunium persicum Boiss after caesarean section can speed the resumption of postoperative bowel motility.

RESUMO

BACKGROUND: Insomnia is an important problem in medical sciences students and has implications for their educational progress. The current study aimed to estimate the prevalence of sleep disorders and investigating the impact of sweet almond on quality of sleep in students of the Tehran University of Medical Sciences (TUMS), Tehran, Iran who live in dormitories. METHODS: This is a before-after study conducted in 2017. At first, using the ISI questionnaire prevalence of sleep disorders was determined. Sweet almond was the study intervention. Each day, 10 almonds were given to 446 students for 14 d. At the end of the second week, again ISI questionnaire was filled. SPSS was used to analyze data. The McNemar, Wilcoxson Signed Ranks, and Repeated Measures tests were used. RESULTS: Out of 442 participants, 217 (49.1%) were female. Before intervention, 343 (77.6%) had insomnia and 99 (22.4%) had normal sleep. After intervention, 306 (69.2%) had insomnia and 136 (30.8%) had normal sleep. Having sweet almond for two weeks is associated with reducing insomnia (P<0.05). Investigating the almond impact in different categories also showed that it has a reducing impact on severe, mild, weak and normal sleep categories (P<0.05). CONCLUSION: Sweet almond has impacts on quality of sleep of those students of the TUMS that are living in dormitories. Intervention programs to improve quality of sleep are necessary and with regard to the high prevalence of insomnia, students must be protected, guided and consulted.

RESUMO

A 32-yr-old man with a 10-yr history of scalp seborrhea referred to Skin and Stem Cell Research Center, Tehran, Iran, in 2015. He suffered from scalp seborrhea. Concurrent gastrointestinal symptoms and the changes in the clinical symptoms after consumption of the polyherbal traditional drug called Triphala are discussed. The scalp sebum was measured with a Sebumeter SM815. Gastrointestinal symptoms were followed using a valid questionnaire. After two months of treatment, scalp sebum secretion had decreased substantially. The patient also experienced remarkable improvement in gastrointestinal symptoms. Considering the positive effect of this known and safe polyherbal drug on skin sebum, it is an appropriate option for detailed large-scale clinical trials.

RESUMO

INTRODUCTION: Traditional Persian Medicine (TPM) was the prevailing practice of medicine in the Eurasia region up through the 18th century, a practice of medicine stemming back to Hippocrates and to the 5000 year old civilization of the region. It is a school of medicine which touches on many a delicate points which may seem unimaginable within the realm of modern allopathic medicine. This practice of ancient medicine besides shedding light on various possible theoretical modern day disorders serves as a vast resource for therapeutics. In this paper, we present study of the manuscripts of this ancient medical practice in search of symptom presentations coinciding with presentation of multiple sclerosis (MS). MATERIAL & METHOD: This paper represents a comprehensive search through TPM texts and manuscripts with the intention to seek possible clues on MS from potentially valuable age-old resources. We predominantly focused our search on the works of five eminent physicians of Medieval Persia: Avicenna (980-1037 AD), Haly Abbas (949-982 AD), Rhazes (865-925 AD), Averroes (1126-1198 AD) and Jorjani (1042-1137 AD). RESULTS: In this paper, the authors attempt a theory and conclude with high probability that a conjunction of a series of signs, symptoms found in TPM texts under the terms khadar, isterkha and falej form the symptoms and the disease pattern of modern day MS. This theory draws upon existent similarities in terms of disease pathology, disease patterns and predisposing factors seen between MS and the related morbidities within Persian Medicine. CONCLUSION: We recommend further examinations of such potentially valuable long-standing resources, examining the diagnoses and treatments as set forth by Persian Medicine through international collaboration within the global scientific community.

RESUMO

BACKGROUND: Diaper dermatitis (DD) is a common inflammatory disorder in infants, including newborns. OBJECTIVES: This study aimed to compare the effects of a traditional medicine product (containing natural henna oil 25%) and hydrocortisone 1% cream on DD in infants. PATIENTS AND METHODS: In a triple-blind, randomized trial, 82 children aged two years or less were randomly divided into two groups of 41 children each to receive either hydrocortisone ointment or henna medicinal product. Infants were treated 3 times a day for 5 days. The severity of dermatitis was assessed on the first, third, and fifth days using a six-point scale. The study was conducted in 2013 in a children teaching hospital in Qazvin, Iran. RESULTS: Both groups showed an improvement in the severity of DD (mean DD severity on the first, third and fifth days, respectively, was 3.20, 1.39, and 1.20 in the henna group versus 3.20, 2.05, and 1.90 in the hydrocortisone group; P < 0.001). The henna group showed a better response when compared with the hydrocortisone group: the rate of improvement on the fifth day of treatment was 90.2% (37 of 41 children without erythema) in the former versus 61% (25 of 41 patients) in the latter (P = 0.042). No significant side effects were observed in both the groups. CONCLUSIONS: Henna, a traditional medicine product, can be considered an effective and appropriate treatment for DD in infants and children.

RESUMO

CONTEXT: Recurrent aphthous ulcer (RAU) is an oral disease and the most common oral lesion, with 2% to 66% of the world's population infected annually. Its prevalence is about 25% in Tehran and 27.6% in Mashhad. The etiology of RAU is multifactorial. Aphthous risk factors include: immunological factors, psychological factors, stress, trauma, sensitivity, family history, blood disorders, malnutrition, and use of certain medications, It should be noted that the best treatment for RAU is the topical application of drugs. The use of topical treatments is recommended not only because the drug can directly impact the source of the disease, but also systemic side effects of the drug are reduced. Treatment of RAU has been considered in Iranian traditional medicine (ITM), and is covered in therapeutic books. The use of herbs in RAU has a centuries-old history; accordingly, extensive research should be conducted for this treatment of the disease. EVIDENCE ACQUISITION: Iranian medical sources were reviewed and effective plants used in the traditional treatment of RAU were found and compared with new findings. Finally, we have created a table listing the plants that are part of the therapeutic protocol for RAU. RESULTS: Based on this article we can explain some of traditional pharmacological effects of plants and how these plants can be a source for a cure. CONCLUSIONS: The plants listed can be used as a prediction of RAU management. Of course, there are is no evidence for curing RAU by some of these plants in allopathic medicine, and the further investigations in this area could lead to the discovery of a new drug.

RESUMO

OBJECTIVE S: Mucoadhesive disc is one of the various routes of drug delivery for curing buccal disease. MATERIALS AND METHODS: Every discs containing 70 mg stem bark extract of Ziziphus jujuba were formulated by using Carbopol 934, PVP k30 and gelatin as polymers. Discs were made by granulation and direct compression. Discs were standardized based on the total phenol. Properties such as in vitro and in vivo mucoadhesion, drug release, water uptake, and disintegration were carried out. RESULTS: Discs showed excellent mucoadhesion and released high amount of the active ingredients (47%) immediately and completed after approximately the first hour. They had a good adhesion in buccal cavity. CONCLUSION: This study showed that the kinetics of release of the active substance from the mucoadhesive disc obeyed the zero order kinetic and didn't follow the fick's law. The water uptake and dissolution (DS), increased with the passing of time.

RESUMO

BACKGROUND: Nutritional deficiency, bleeding, and inflammation are three main causes of anemia. On the other hand, erythropoietin (EPO) production, iron availability, and a healthy bone marrow are essential for erythropoiesis. Recently, recombinant human erythropoietin (rhEPO) has been used to treat the patients already taking iron supplements. In Iranian traditional medicine literature, much has been written about anemia and its treatment. OBJECTIVES: This study aimed to review Iranian traditional medicine theories in the treatment of anemia. MATERIALS AND METHODS: In the present study, authors have attempted to find the etiology and pathogenesis of anemia in Iranian traditional Medicine Literature and the views of ancient physicians in this field. RESULTS: Our findings proved that Iranian traditional medicine defined anemia as blood humor production dysfunction, which is caused by several reasons mainly hepatic dysfunction. Thus, liver is supposed to be the most important organ in this regard. This will make considering hepatoprotective medicines in anemia even in patients with non-hepatic problems. CONCLUSIONS: The article presents the relation between anemia and liver dysfunction viewed by Iranian traditional medicine as an important finding in designing a treatment plan. Despite the new findings on the evaluation of liver function (i.e. laboratory tests), it seems that further studies for earlier evaluation of liver function in anemia are highly required.

RESUMO

Some physicochemical parameters of honey have been introduced by the International Honey Commission to evaluate its quality and origin but processes such as heating and filtering can affect these parameters. In traditional Iranian medicine, deslagging process involves boiling honey in an equal volume of water and removing the slag formed during process. The aim of this study was to determine the effects of deslagging process on parameters of color intensity, diastase evaluation, electrical conductivity, pH, free acidity, refractive index, hydroxy methyl furfural (HMF), proline and water contents according to the International Honey Committee (IHC) standards. The results showed that deslagged honey was significantly different from control honey in terms of color intensity, pH, diastase number, HMF and proline content. It can be concluded that the new standards are needed to regulate deslagged honey.

RESUMO

CONTEXT: In modern phytotherapy, Stachys lavandulifolia Vahl., a type of Stachys also known as Mountain Tea (Chay-e-Kouhi) has been widely studied based on its botanical and therapeutic characteristics over the recent decades. EVIDENCE ACQUISITION: The present study investigated morphology, botanical characteristics, and some therapeutic activities of this plant and compares them with those of Marmazad, as the traditional equivalent of Stachys in traditional iranian medicine (TIM), to evaluate the similarities between Stachys and Marmazad. RESULTS: In this study by exploring morphology, botanical properties and therapeutic activities of Stachys from modern botany and Marmazad in TIM, comparing them and considering similarities between those botanical properties and some of therapeutic activities this outcome was drawn that what had been known as Marmazad in TIM nowadays is equal to Stachys or Chay-e-Kouhi in modern botany. CONCLUSIONS: The achieved findings from this comparison between botanical characteristics and therapeutic activities of Stachys based on modern researches and those of Marmazad by referring to traditional manuscripts revealed significant similarities between them. Also, there were some applications mentioned for Marmazad in TIM which could help new researchers in modern phytotherapy to deal with those dimensions of this herb which are not worked out yet.

RESUMO

PURPOSE: To investigate the effect of tinted filters on visual acuity (VA), contrast sensitivity and patient satisfaction in diabetic retinopathy associated with low vision. METHODS: In a prospective study, 51 patients with diabetic retinopathy and low vision were assessed. We chose a simple random sampling method and used the patient's files for data collection. LogMAR notations were applied for assessing VA and a contrast sensitivity chart (CSV-1000) was employed for measuring contrast sensitivity. First, measurements were performed without tinted filters and then using them. Appropriate lenses were given to the patients for 2 days, and they were questioned about their satisfaction using them in different places. RESULTS: A total of 20 male and 31 female patients with mean age of 57.3 years participated in the study. With a 527 ± 10 nm filter, mean VA improved significantly (P ≤ 0.05). Using the 527 ± 10 nm and 511 ± 10 nm filters, mean contrast sensitivity was improved significantly at 3 and 6 cycles/degree frequencies (P < 0.05). The effect of other filters on VA and contrast sensitivity was not significant. Patient satisfaction rate was generally high. CONCLUSION: Tinted filters are able to rehabilitate low-vision patients due to diabetic retinopathy. The 527 ± 10 and 511 ± 10 nm wavelength filters improved contrast sensitivity and the 527 ± 10 nm filter improved VA to some extent. Further investigations are recommended to assess the effect of these filters in patients with other causes of low-vision.
