Traditional and modern aspects of hemorrhoid treatment in Iran: a review / 中西医结合学报

Hemorrhoidal disease is a prevalent anorectal condition which is generally not managed well with current pharmacologic interventions. However, in Iranian traditional medicine (ITM) there are numerous plants with hemorrhoid-healing properties. The present research assembled plants with hemorrhoid-healing properties in ITM; their related pharmacological effects, phytochemical constituents and mechanisms of action in the modern medicine were also gathered. For this purpose, leading ITM textbooks were searched for plants with hemorrhoid-healing effects. Further, in vitro, in vivo and clinical studies on the most cited species were considered using scientific databases. Studying ITM textbooks revealed 37 medicinal plants with hemorrhoid-healing effects. Among the mentioned herbal medicines, six species, including Allium ampeloprasum, Phyllanthus emblica, Aloe vera, Terminalia chebula, Vitis vinifera and Commiphora mukul, had the largest number of related pharmacological effects documented in scientific databases. These herbs from ITM should be considered as important resources for producing novel drugs for hemorrhoid treatment.

Effect of aromatherapy with peppermint oil on the severity of nausea and vomiting in pregnancy: a single-blind, randomized, placebo-controlled trial

Background: Nausea and vomiting are common complaints in the first half of pregnancy. These symptoms can significantly affect a person's personal and professional life. Aromatherapy is one of the types of complementary medicine that is used in the treatment of nausea and vomiting

The objective of this study was to determine the effect of aromatherapy with peppermint oil on the severity of nausea and vomiting of pregnancy [NVP]

Methods: This was a single-blind clinical trial that was conducted on 56 pregnant women with mild to moderate severity of NVP and 6 to 20 weeks of gestational age. After the determination of gestational age and base severity of NVP in each woman, they were randomly assigned to one of the two groups: peppermint oil [n=28] or placebo [n=28]. Inhalation aromatherapy was done for four days and at the end of each day,they responded to the Pregnancy Unique Quantification of Emesis/Nausea questionnaire [PUQE]. The data obtained were analyzed with Mann-Whitney test and ANOVA with repeated measures using SPSS software version 22. Also, the level of significance was p<0.05

Results: Although the severity of NVP in each intervention group significantly decreased [p<0.001], the comparison of the severity of NVP during the study period and at the end of it was not statistically significant between the placebo and intervention groups

Conclusion: According to the possibility of neurological mechanisms causing NVP, the effect of aromatherapy with peppermint oil and placebo were the same in this study. This similarity can be due to psychological impacts of intervention on pregnant women

Melissa officinalis acidic fraction protects cultured cerebellar granule neurons against beta amyloid-induced apoptosis and oxidative stress

Objective: Extracellular deposition of the beta-amyloid [A beta] peptide, which is the main finding in the pathophysiology of Alzheimer's disease [AD], leads to oxidative damage and apoptosis in neurons. Melissa officinalis [M. officinalis] is a medicinal plant from the Lamiaceae family that has neuroprotective activity. In the present study we have investigated the protective effect of the acidic fraction of M. officinalis on A beta-induced oxidative stress and apoptosis in cultured cerebellar granule neurons [CGN]. Additionally, we investigated a possible role of the nicotinic receptor

Materials and Methods: This study was an in vitro experimental study performed on mice cultured CGNs. CGNs were pre-incubated with different concentrations of the acidic fraction of M. officinalis for 24 hours, followed by incubation with A beta for an additional 48 hours. CGNs were also pre-incubated with the acidic fraction of M. officinalis and mecamylamin, followed by incubation with A beta. We used the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide [MTT] assay to measure cell viability. Acetylcholinesterase [AChE] activity, reactive oxygen species [ROS] production, lipidperoxidation, and caspase-3 activity were measured after incubation. Hochst/annexin V- fluorescein isothiocyanate [FITC]/propidium iodide [PI] staining was performed to detect apoptotic cells

Results: The acidic fraction could protect CGNs from A beta-induced cytotoxicity. Mecamylamine did not abolish the protective effect of the acidic fraction. AChE activity, ROS production, lipid peroxidation, and caspase-3 activity increased after A beta incubation. Pre-incubation with the acidic fraction of M. officinalis ameliorated these factors and decreased the number of apoptotic cells

Conclusion: Our results indicated that the protective effect of the acidic fraction of M. officinalis was not mediated through nicotinic receptors. This fraction could protect CGNs through antioxidant and anti-apoptotic activities

Formulation of a traditionally used polyherbal product for burn healing and HPTLC fingerprinting of its phenolic contents

Nowadays, plants have been considered as powerful agents for treatment of disorders regarding to their traditional use. In Iranian Traditional Medicine [ITM], plants have a special role in the treatment of various diseases. Burns with their devastating outcomes have been discussed in ITM as well. In the present study, a polyherbal ointment [PHO], retrieved from ITM, was formulated for burn healing and it's HPTLC fingerprint was prepared. Aqueous extracts of Malva sylvestris and Solanum nigrum leaves and oily extract of Rosa damascene petals [4.85%, 4.85% and 33%, respectively] were added to white beeswax, eucerin and white petrolatum as ointment base. In addition to the microbiological tests, physical stability and rheological behavior of the product were assessed. Fingerprinting of phytochemical constituents of PHO was performed by using silica gel plates and toluene: ethyl acetate: acetic acid [60: 40: 1] and ethyl acetate: formic acid: acetic acid: water [100: 11: 11: 10] as mobile phases. The results showed that PHO was stable towards physical changes and successfully passed microbiological tests. Moreover, PHO exhibited plastic behavior which is in favor of a topical burn product. In addition, HPTLC fingerprinting of PHO demonstrated the presence of several phenolic constituents corresponding to the plant extracts. Regarding to the role of phenolic compounds in wound healing process, PHO could be an appropriate candidate for burn healing with respect to its traditional use in ITM. Moreover, HPTLC fingerprinting could be utilized as an applicable method for quality control of the prepared formulation

Historical applications of Nigella sativa L. [black cumin] in the treatment of Zokam and Nazleh in Persian medicine

Using Nigella sativa L. [Black cumin], in traditional medicine, dates back to Tutankhamen, the pharaoh of Egypt. There are aboundant historical and religious evidence implying the importance of these curative seeds. Traditionally, they have been used for various therapeutic purposes. Zokam and Nazleh [ZaN] are two nasal diseases used to be treated by these medicinal seeds. Traditional Persian Medicine [TPM] classifies each of these diseases into warm and cold types. Comparing symptoms, Warm ZaN resembles Allergic rhinitis and cold ZaN is similar to Rhinosinusitis. Many documents have been found in TPM references that explain different ways for preparing Black cumin seeds for the treatment of cold ZaN, but there is no evidence for treating warm ZaN. In recent years, many original articles have been written to explain the therapeutic qualities of these curative seeds. They exhibit that Black cumin seeds, in addition to increasing the mucociliary clearance, histamine release inhibition and antihistaminic effects, have anti-inflammatory, antibacterial, antibacterial biofilm formation. Consequently, they confirm the application of Black cumin in the treatment of rhinosinusitis or cold ZaN

Comparison of neuroprotective effects of Melissa officinalis total extract and its acidic and non-acidic fractions against a beta-Induced toxicity

Alzheimer's disease [AD] is a neurodegenerative disease that was characterized with deposit of beta amyloid [A beta] aggregate in senile plaque. Oxidative damage to neurons and loss of cholinergic neurons in forebrain region are observed in this disease. Melissa officinalis is a medicinal plant from Lamiaceae family, used traditionally in the treatment of cognitive disorders. It has cholinomimetic and potent antioxidant activity. In the present study, we investigated the possible neuroprotective effects of total ethanolic extract, acidic and nonacidic fraction of Melissa officinalis on A beta-induced cytotoxicity and oxidative stress in PC12 cells and also measured their in-vitro anticholinesterase activity. PC12 cells were incubated with the extract and fractions prior to the incubation with A beta and cell toxicity was assessed by MTT assay. In addition, productions of reactive oxygen species [ROS], Malondialdehyde [MDA] as a biomarker of lipid peroxidation and glutathione peroxidase activity were measured. Pretreatment of cells with total extract and acidic fraction [not non-acidic fraction] had protective effect against A beta-induced oxidative changes and cell death. In concentrations in which both total extracts of an acidic fraction showed neuroprotective effects, inhibition of cholinesterase activity was not significant. Then, the protective effects of Melissa officinalis total extract and acidic fraction were not attributed to their anticholinesterase activity. Acidic fraction showed more potent protective effect compared to the total extract, leading to the fact that polyphenolic compounds and terpenoic acids are the most effective components in the total extract concentrated in this fraction
