RESUMEN
OBJECTIVE: Coronavirus disease 2019 (COVID-19) is a debilitating disease with numerous medical and non-medical consequences. Our study aimed to evaluate the efficacy of Persian barley water in controlling the clinical outcomes of hospitalized COVID-19 patients. PATIENTS AND METHODS: This was a single-blind, add-on therapy, randomized controlled clinical trial conducted in Shiraz, Iran, from January to March 2021. One hundred hospitalized COVID-19 patients with moderate disease severity were randomly allocated to receive routine treatment (per local protocols) with or without 250 ml of Persian barley water (PBW) daily for two weeks. Clinical outcomes and blood tests were recorded before and after the study period. Multivariable modeling was applied using Stata software for data analysis. RESULTS: The PBW product passed our standardization and safety assessments. Length of hospital stay (LHS) was 4.5 days shorter in the intervention group than the control group regardless of history of cigarette smoking (95% confidence interval: -7.22, -1.79 days). Also, body temperature, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and creatinine significantly dropped in the intervention group compared to the control group. No adverse events related to PBW occurred. CONCLUSIONS: This clinical trial demonstrated the efficacy of PBW in minimizing the LHS, fever, and levels of ESR, CRP, and creatinine among hospitalized COVID-19 patients with moderate disease severity. More robust trials can help find safe and effective herbal formulations as treatments for COVID-19.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional medicine has a long history and plays an important role in the Kurdish community in Sarvabad county, Kurdistan province, Iran. Despite the great diversity of medicinal plants, cultural history, and variety of herbal medicine uses among Kurdish tribes, very few cohesive ethnopharmacological studies of this unique region are available in the scientific literature. Our study tried to gather medicinal plant species and document the associated indigenous knowledge of the ethnic groups in the Sarvabad district for the first time. MATERIALS AND METHODS: Ethnobotanical data were collected from 92 local informants through semi-structured questionnaires, open interviews, and field surveys during a period of two years (2018-2020). The statistical analysis included use reports (UR) for each species, and informant consensus factor (FIC) to evaluate the data. RESULTS: In the present study a total of 156 plant species belonging to 58 botanical families, were recorded for the treatment of 16 diseases categories. The most represented families were Lamiaceae, followed by Asteraceae, and Apiaceae. The most frequently cited plant species with the highest use report (UR) were Pistacia atlantica (161), Hymenocrater longiflorus (128), Melissa officinalis (124), Cyperus rotundus (114), Thymus transcaspicus (112), and Quercus brantii (109). Psychological (ICF = 0.96), musculoskeletal (ICF = 0.94), and digestive (ICF = 0.93), followed by respiratory problems (ICF = 0.92) showed the highest informant consensus factors among all ailment categories. Most herbal remedies were consumed as decoction. Leaves (28.5%) were the most widely used plant parts, followed by flowers (18.7%), aerial parts (14.5%), seeds (13.2%), and terrestrial parts (8.41%). Some interesting new medicinal uses for native and common species were reported. Species such as Cyperus rotundus, Hymenocrater longiflorus, Anthriscus nemorosa, Pistacia atlantica and Quercus brantii would be interesting targets for drug discovery and are suggested for further investigations. CONCLUSION: The plant use reports, and quantitative data analyzed demonstrate that the relative importance of plant species and shared knowledge of herbal therapies among Kurdish communities of the Sarvabad county is still rich. A systematic study and evaluation of the biological activity of highly consumed plants, could identify the possible mechanism of action.

ETHNOPHARMACOLOGICAL RELEVANCE: Carthamus tinctorius L. (Safflower) has been widely recommended to treat metabolic disorders in traditional herbal medicine in Persia, China, Korea, Japan, and other East-Asian countries. The anti-hypercholesterolemic and antioxidant effects of this plant have been well documented, but its protective effects against Metabolic Syndrome (MetS) have not been fully illustrated. AIM OF THE STUDY: The present study aimed to evaluate the effects of safflower oil on MetS risk factors. MATERIALS AND METHODS: In this randomized, double-blind, placebo-controlled clinical trial, 67 patients with MetS were administered either divided 8 g safflower oil or placebo daily for 12 weeks. All patients were advised to follow their previous diets and physical activities. RESULTS: Safflower oil resulted in a significant reduction in waist circumference (-2.42 ± 3.24 vs. 0.97 ± 2.53, p<0.001), systolic blood pressure (-8.80 ± 9.77 vs. -2.26 ± 8.56, p = 0.021), diastolic blood pressure (-3.53 ± 7.52 vs. -0.70 ± 6.21, p = 0.041), fasting blood sugar (-5.03 ± 10.62 vs. 2.94 ± 7.57, p = 0.003), and insulin resistance (-0.59 ± 1.43 vs. 0.50 ± 1, p = 0.012), but an increase in adiponectin level (0.38 ± 0.99 vs. -0.09 ± 0.81, p = 0.042) in the treatment group in comparison to the placebo group. The results revealed a direct relationship between leptin level and Body Mass Index (BMI) in both groups (p<0.001). In addition, increase in BMI resulted in a non-significant decrease in adiponectin level in both groups. Moreover, no significant difference was observed between the two groups regarding lipid profiles, leptin serum level, serum creatinine concentration, and other outcomes. CONCLUSION: Safflower oil without lifestyle modification improved abdominal obesity, blood pressure, and insulin resistance in patients with MetS.

Osteoarthritis (OA) is known to be the leading cause of pain and disability in the elderly. The prevalence of this disease in adults over 60 years was 9.6% in men and 18% in women. The therapeutic goals of this disease generally include pain relief with the least side effects, improvement of articular function and improvement of life, in which pharmacological and nonpharmacological treatments are performed in different protocols. Due to the common side effects of pain relievers and complaints after invasive joint surgeries, there is a growing interest in the use of Traditional and Complementary protocols in OA treatment. In this paper, different sources of Traditional Persian Medicine (TPM) were searched to obtain any evidence evaluating any medicinal plants in the management of OA. Over 250 effective medicinal plants for the treatment of OA have been introduced in these sources, and by searching electronic databases including PubMed and Scopus, we have found that of these plants, 39 have direct or indirect evidence in the treatment of this complication by different mechanism of actions such as effect on Body mass index (BMI), obesity and dyslipidemia, anti-inflammatory, anti-nociceptive and antioxidant activity. The most important medicinal plants with direct evidence in the management of OA are Allium sativum, Commiphora mukul, Linum usitatissimum, Matricaria chamomilla, Nigella sativa, Zingiber officinale, and Piper nigrum. Medicinal plants seem to be a valuable source for discovering and identifying new drugs for treatment of OA; however, since most of the studies are preclinical, further clinical trials are required to achieve more conclusive results.

Sciatica is a common back pain caused by irritation of the sciatic nerve. Current pharmacologic therapies have proven inadequate for many patients with sciatic pain. On the other hand, there is a globally increasing demand for the use and administration of natural medicaments for this disorder. Traditional Persian Medicine (TPM) is a school of medicine and a medicinal plant-based resource for clinical studies put forward by Persian scholars. The aim of the present study is to gather and study the effectiveness of all medicinal plants from five main Persian pharmacopeias. Furthermore, different databases such as PubMed and Scopus have been checked to derive relevant activities for these plants. In all, 99 medicinal plants related to 42 families have been authenticated. Asteraceae and Apiaceae were the most frequent families and roots and seeds were the most reported botanical parts. The employed routes of administration were oral (54%), topical (33%) and rectal (13%). Anti-inflammatory, analgesic activity and antinociceptive properties of medicines are known as some main mechanisms to manage sciatic pain. These functions are possessed by 30%, 15%, and 15% of the studied plants, respectively. Medicaments that can be introduced as lead agents for further investigation are Zingiber officinale Roscoe, Olea europaea L., Strychnos nux-vomica L and Artemisia vulgaris L which showed all of these properties in previous studies. Hence, conducting adducible clinical trials using these lead agents may lead to novel drugs with lesser undesirable and much more therapeutic effects on controlling sciatic pain.

BACKGROUND: Cancer is one of the most prevalent diseases associated with heavy complications in treatment. Mucotoxic cancer therapies such as head and neck radiotherapy and some of the chemotherapy agents may lead to oral mucositis. In addition to its economic consequences, mucositis also affects patients' quality of life. In Traditional Persian Medicine (TPM) manuscripts, several medicaments have been suggested for the treatment of mucositis. OBJECTIVE: Considering the public welcome for herbal medicine, the current evidence-based review study is conducted to investigate the herbal remedies which have been proposed for oral mucositis in TPM. METHODS: At first, a comprehensive survey was done on Qanon fi al-Teb, which is the most important textbook of TPM; then the scientific name of the herbs was authenticated according to the botanical textbooks. At last, data banks including Scopus, Pubmed, Web of science and Science direct were investigated for possible relevant properties of each medicinal plant in the literature. RESULTS: In total, 30 herbs are introduced in this study. According to the registered documents, 18 herbs are reported to have antioxidant, anti-inflammatory, antimicrobial, anti-nociceptive and wound healing properties of which the therapeutic effect of only a few herbs including Glycyrrhiza glabra, Malva sylvestris, Morus nigra, Punica granatum, and Solanum nigrum were directly evaluated against oral mucositis on the literature. CONCLUSION: Despite the lack of human studies on mucositis for the other discussed herbs, their related pharmacological properties can be considered for new natural drug discovery supported by medieval and traditional experiments.

BACKGROUND: Vitiligo is a hypopigmentation disorder that affects 1% of the world's population. Vitiligo causes white spots on the skin, mucous membranes, or white hair by destroying skin melanocytes. The pathogenesis of vitiligo is unknown but autoimmune, autocytotoxic, and neural mechanisms are suggested. According to the autoimmune theory, in people with vitiligo, immune cells invade and damage melanocytes. T cells are more commonly present in vitiligo patients' skin and remain in the lesion site, which is composed of CD8 and CD4 T cells. Many studies have been conducted on the presence and role of cytokines such as interleukins and interferongamma (IFN-γ) in the vitiligo process. AIM: This study aimed to introduce herbs effective against vitiligo from the perspective of Persian medicine and to investigate their possible therapeutic mechanisms with the possible effects of herbs on autoimmune mechanisms. METHODS: For this purpose, keywords were used to extract data from Persian medicine textbooks, and then relevant scientific databases, including Google Scholar, PubMed, Web of Science, and Scopus were examined. RESULTS: It was found that Persian medicine scholars used 50 different medicinal plants to treat and reduce the complications of vitiligo, and recent scientific studies have proven immune-regulating properties and reducing the effect of many of them on cytokines. CONCLUSION: According to scientific evidence on immunomodulatory effects, new research into the effects of these plants on vitiligo can lead to the discovery of new drugs and approaches for treating this disease.

BACKGROUND: Cough is one of the most common medical symptoms for which medical advice is sought. Although cough is a protective reflex responsible for clearing the airways from secretions and foreign bodies, it can be a troublesome symptom that causes discomfort to patients. Due to the increasing interest in herbal remedies in both developed and developing countries, in the current study, we aimed to overview medicinal herbs containing essential oils used as antitussive agents according to Traditional Persian Medicine (TPM) textbooks. We summarized the relevant scientific evidence on their possible pharmacological effects. METHODS: To collect the evidence for the treatment of cough or "seaal" (cough in ancient books) from TPM sources, five main medicinal Persian manuscripts were studied. The antitussive herbs were listed and their scientific names were identified and authenticated following botanical reference books. ScienceDirect and PubMed online databases were searched for related mechanisms of action of the reported medicinal plants. RESULTS: Forty-nine herbs containing essential oils have been recommended in TPM for the treatment of cough; 21 of them had at least one known mechanism of action for cough suppression in the scientific literature. According to this review, most of the cited medicinal plants were assessed for either nitric oxide inhibitory or antitussive/expectorant activities. CONCLUSION: In addition to advantageous effects of antitussive herbs recommended by TPM, the present review highlighted some recent evidence-based data on these promising herbs that could be used as an outline for future research on their medicinal use.

INTRODUCTION: According to Rome IV, functional dyspepsia is diagnosed with the presence of dyspepsia in the absence of organic or metabolic causes. FD caused by several factors, such as impaired gastric accommodation and hypersensitivity to gastric distention. Several studies have reported the effectiveness of herbal medicine on FD. This article, thus, reviews Persian herbal medicine in FD. METHODS: Electronic databases, including Pubmed, Scopus, Cochrane, Embase, Web of science and Ovid, were searched so as to find clinical articles related to dyspepsia and herbal medicine by July 2019. Our search strategies were traditional medicine, complementary and alternative medicine, herb, plant, and dyspepsia. We excluded all articles except Persian clinical trials. RESULTS: We found 34 clinical trials with 15 herbs and 4 compound herbal remedies like Asparagus racemosus, Brassica oleracea, Cynara scolymus, Ocimum basilicum, Mentha longifolia, Mentha pulegium, Mentha piperata, Pimpinella anisum, Nigella sativa, Mastic gum, Curcuma longa, Pistatio Atlantica, Glycyrrhiza glabra, Solanum tuberosum and Zingiber officinale and compound remedies of Rosa damascene & Crocus sativus, Trachyspermum copticom & Apium graveolence, Carum carvi & Mentha pipperata, Gingiber officinalis & Cynara scolymus are effective in functional dyspepsia. CONCLUSION: Many people use herbal and traditional remedies for the treatment of disorders such as gastrointestinal disorders, especially in Asian countries. Several studies reported the efficacy of herbal medicine in functional dyspepsia. Although their mechanisms are not fully understood, it seems they can modulate GI motility and improve symptoms of FD.
