Recent Therapeutic Interventions of Fenugreek Seed: A Mechanistic Approach.

Fenugreek seeds have widespread relations with Ayurveda, Unani, and Arabic medicine. The seeds were useful for the treatment and prevention of different ailments. Fenugreek (Trigonella foenum-graecum) or methi is from the Leguminosae family and are primarily known for its anti-diabetic and hypocholesterolemic activities. The germinated fenugreek seeds were used in the treatment of E.coli infection in Germany and France. The important phytoconstituents responsible for such medicinal applications are saponins, polyunsaturated fatty acids, galactomannans, trigonelline, and 4-hydroxy isoleucine. Flavonoids, apigenin 6,8-di-C-glucoside, apigenin-6-C-glucosyl-8-C-galactoside, 6-Cgalactosyl- 8-C-arabinoside are the chief ingredients of fenugreek seeds; responsible for reducing blood glucose while given to diabetic rats, whereas important flavones are epigenin, luteolin and vitexin. The other major bioactive components in fenugreek seeds are polyphenols like rhaponticin and isovitexin. Fenugreek seeds contain phosphorus and are categorized into different classes such as inorganic phosphorus, phospholipids, phytates, phosphor-proteins, and nucleic acid. Germinated seeds profusely filled with amino acids with amino acids, proteins, ascorbic acid, sugars. Further, this review shares information about the recent therapeutic intervention not covered earlier; on in vivo and in vitro and some clinical applications against certain interesting ailments other than older applications. This review includes certain nano delivery systems of Fenugreek seeds and their medicinal application.

A Review Article About Some Herbs Affecting Vitiligo Based on Avicenna's Canon.

BACKGROUND: Vitiligo is a pigmentary disorder characterizing by white macules due to loss of melanocytes. Vitiligo affects about 1 to 4% of people around the world. The treatment of vitiligo has a high cost and the long process of treatment in spite of no complete remedy. It has various psychological side-effects such as depression and anxiety affecting the quality of life seriously. Avicenna in his Canon treated these patients over a thousand years ago. This study aimed to introduce some herbal drugs in vitiligo based on the Canon of Avicenna besides the conventional medical treatments. METHODS: This is a review study, according to the Canon with the term Baras and also searching through the electronic websites with the keywords vitiligo, treatment, and herbal drugs. RESULTS: The study found some herbs affecting the vitiligo from the Canon. CONCLUSION: The researchers suggest conducting clinical trials on the patients with vitiligo based on the Canon besides the conventional techniques to obtain a better result in the treatment.

Euryops arabicus displays anti-inflammatory activities in experimental models.

ETHNOPHARMACOLOGICAL RELEVANCE: Euryops arabicus (Asteraceae) is grown in Arab Peninsula. Its aerial parts possess ethnomedicinal applications against several inflammatory conditions. AIM OF THE STUDY: To evaluate the anti-inflammatory activity of Euryops arabicus (E. arabicus) organic extract as well as its major polymethoxylated flavonoids. MATERIALS AND METHODS: Acute toxicity of the total extract of E. ararbicus was evaluated by assessing LD50. In vivo anti-inflammatory activity was evaluated in rats injected with carrageenan in the plantar area. Paw edema volume, histological changes and rats'stair climbing and motility were assessed. In vitro anti-inflammatory activity of the isolated compounds was evaluated in peripheral blood mononuclear cells (PBMCs) challenged with carrageenan. Inflammation markers were assessed in cellular lysates and collected media. RESULTS: The extract was found safe and considered unclassified with an oral LD50 > 2000 mg/kg in rats. Pretreatment of rats with a total extract of E. arabicus at doses of 100 and 250 mg/kg significantly inhibited carrageenan-induced increase in paw edema volume and histopathological changes. Also, it significantly ameliorated diminution of climbing and motility. Phytochemical studies led to the isolation and identification of five polymethoxylated flavonoids. The anti-inflammatory properties of the isolated compounds were evaluated in carrageenan-challenged peripheral blood mononuclear cells (PBMCs). All compounds exhibited appreciable antioxidant activities. Further, pre-incubation of the cells with the isolated metabolites significantly ameliorated the rise in cyclo-oxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) and monocyte chemoattractant protein-1 (MCP-1) induced by carrageenan challenge. Further, the compounds inhibited the leakage of interleukin-1ß (IL-1ß), interleukin-6 (IL-6) and myeloperoxidase (MPO) in media collected from stimulated cells. CONCLUSION: E. arabicus exhibited in vivo anti-inflammatory effects in the carrageenan model as it ameliorated rat paw edema, histopathological changes and movement dysfunction. in vitro activity of isolated compounds was confirmed in stimulated PBMCs. Thus, the anti-inflammatory activity of E. arabicus can be attributed, at least partly, to its anti-oxidant, anti-inflammatory and anti-chemotactic properties.

Efficacy of oral administration of licorice as an adjunct therapy on improving the symptoms of patients with Parkinson's disease, A randomized double blinded clinical trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Licorice preparations are used as neuroprotective remedies in Persian ethnomedicine, in order to prevent from disabilities in neurodegenerative conditions like Parkinson's disease (PD). AIM OF THE STUDY: This study was designed to determine the licorice (root of Glycyrrhiza glabra L.) effectiveness as an adjunct treatment in the PD management. MATERIAL AND METHODS: In this double-blinded trial, 128 patients were assessed for eligibility criteria. Seventy-eight patients were ineligible and 11 of them refused from participating. Thirty-nine PD patients (YAHR staging ≤ 3) were divided into two groups by random. The patients received oral licorice or placebo syrups with a dose of 5 cc, twice a day for 6 months. High-performance liquid chromatography and spectrophotometric instruments determined licorice syrup constituents. The patients' situation for Unified Parkinson's rating scale (UPDRS) was assessed every 6 weeks for the duration of six months. In addition, patients' blood pressure, blood glucose, sodium and potassium levels, quality of life and dizziness were determined. RESULTS: Six weeks after intervention, total UPDRS, daily activities and tremor were significantly improved with a considerable effect size. A significant better motor test and rigidity scores were observed 4 months after licorice intake (p > 0.05). No electrolyte abnormality, significant changes in blood pressure or blood glucose levels were observed during the study. Each 5cc of syrup contained 136 mg of licorice extract with 12.14 mg glycyrrhizic acid, and also 136 µg of polyphenols. CONCLUSION: The licorice intake could improve the symptoms in PD patients without serious adverse events.

Natural Treatments for Fissure in Ano Used by Traditional Persian Scholars, Razi (Rhazes) and Ibn Sina (Avicenna).

Most cases of chronic fissure do not respond to medical treatment. Razi and Ibn Sina were 2 of the best-known scientists of ancient Persia. The purpose of this study was to find out new scientific evidence in modern medicine about their recommendations, in order to find certain clues to conduct useful researches in the future. First, treatments of anal fissure mentioned by Razi and Ibn Sina were reviewed. Then, literature search was made in electronic databases including PubMed, Scopus, and Google Scholar. Management of anal fissure according to Razi's and Ibn Sina's practices is done based on 3 interventions: lifestyle modifications, drug treatments, and manual procedures. Almost all remedies suggested by Razi and Ibn Sina have shown their effects on fissure in ano via several mechanisms of action in many in vitro and in vivo studies; Still there is lack of human studies on the subject.
