Antifatigue Effects of the Aqueous Extracts of Myrtle Berries, Apple and Clove: An Animal Study.

Background: Fatigue is one of the most prevalent symptoms, increasing worldwide with no specific medication for fatigue. Iranian traditional medicine (ITM), or Persian medicine, is a reliable source for discovering natural medicine for diseases and their symptoms. Myrtus communis L. (Myrtle), Malus domestica Borkh. (Apple), and Syzygium aromaticum (L.) Merr. & L. M. Perry (Clove) have been utilized as brain and heart tonics in ITM. Based on ITM, cardiac tonics decrease fatigue by enhancing heart function and increasing blood flow to tissues. These plants, particularly myrtle berries, have been utilized as potent enlivening agents that reduce mental fatigue. Objectives: This study aims to investigate the effects of aqueous extracts of these plants on weight-loaded forced swimming (WLFS) tests and three doses of aqueous myrtle extract in an animal model of chronic sleep deprivation-induced fatigue. Methods: Five groups of rats (n = 6) were evaluated: Sham, control, apple-treated, clove-treated, and myrtle-treated groups. After 28 days of treatment, the WLFS test was performed, and swimming time was recorded. Subsequently, central fatigue was induced in rats by chronic sleep deprivation for 21 days. Five groups of rats (n = 6) were evaluated: Sham, control (sleep-deprived, which received water), and three sleep-deprived + treatment groups, which received aqueous myrtle extract (350, 700, and 1000 mg/kg). An open field test on the 20th day and a WLFS test on the 21st day were performed. Results: The myrtle berries significantly increased glucose, reduced lactate dehydrogenase (LDH) levels, and enhanced swimming time. Fatigue caused by chronic sleep deprivation increased malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß), and LDH while decreased superoxide dismutase (SOD), glucose, and swimming time. In all treatment groups, SOD levels and swimming time were increased, whereas MDA, IL-1ß, and TNF-α levels were decreased significantly. Only the 1000 mg/kg dose significantly reduced LDH levels (P < 0.001). The treatment significantly improved the velocity and the total distance moved in the open-field test. Conclusions: According to the results, the myrtle berries reduced fatigue in two animal models, probably due to its phenolic compounds, flavonoids, and polysaccharides.

Effect of Zingiber officinale Roscoe rhizome (ginger) capsule on postpartum pain: Double-blind randomized clinical trial.

BACKGROUND: Postpartum pain contributes to increased irritability and excessive stress in the mother and consequently may inhibit successful breastfeeding, reduce a mother's ability to take care of her baby, and cause an imperfect mother-baby interaction. Evidence suggests the positive effect of ginger on reduction in uterus-associated pain. The objective of this study is to investigate the effect of ginger capsules on postpartum pain. MATERIALS AND METHODS: The present double-blinded, randomized, placebo-controlled trial was conducted in Mahdiyeh Educational Hospital, Tehran. One hundred and twenty-eight mothers having moderate-to-severe pain following vaginal delivery were included. The participants were divided into two groups (A and B). Interventions were performed every 8 h in 24 h. In the first intervention (2 h after the delivery), Group A received 500 mg of placebo capsules (containing chickpea flour) and Group B received 500 mg of Zintoma (ginger rhizome) capsules. In the second and third interventions, Group A received 250 mg placebo capsules and Group B received 250 mg Zintoma capsules. All participants received 250 mg capsules of mefenamic acid in each intervention in addition to ginger or placebo capsules. The pain severity was measured before and half an hour, an hour, and 2 h after each intervention. Statistical analysis was performed using the SPSS software version. 22. The Chi-square, Fisher's, and t tests and the GEE model were applied to assess the pain severity. RESULTS: The average pain severity was not statistically significant between the groups in the beginning of the intervention (P = 0.623). The mean score of pain significantly decreased within the duration of intervention in both groups (P < 0.001); however, the pain severity was significantly lower in the intervention group as compared to the control group at any point after the intervention (P = 0.006). CONCLUSION: Ginger can be used as an effective remedy for postpartum pain relief.

Methanolic Extract from Aerial Parts of Artemisia Annua L. Induces Cytotoxicity and Enhances Vincristine-Induced Anticancer Effect in Pre-B Acute Lymphoblastic Leukemia Cells.

Background: Nowadays, remarkable attention has been drawn towards the effective therapeutic characteristic of natural products targeting cancerous cells. This study aimed to investigate the anti-cancer effect of Artemisia annua extract (AAE), a Chinese herbal medicine alone and in combination with a microtubule binding agent used in ALL treatment, vincristine (VCR), in B-Acute lymphoblastic leukemia (ALL) Nalm-6 and Reh cells. Materials and Methods: Cytotoxic activity of AAE and VCR was determined using MTT assay in Nalm-6, and Reh cell lines and synergism was evaluated using the CompuSyn software. Caspase 3 activity and Annexin/PI staining were performed for apoptosis assessment. The expression level of apoptosis-related genes, caspase 3, Bax and Bcl-2 were determined using real time-PCR. One-way ANOVA and post hoc Tukey multiple comparisons were used for statistical analysis. Results: Our findings revealed that a single administration of AAE exerted an anti-leukemic effect in both ALL-derived cells in a time- and dose-dependent manner. Interestingly, the growth inhibitory activity of the extract was more potentiated when combined with 0.1 and 1 nM VCR through caspase 3-dependent apoptosis. Moreover, real-time PCR analysis showed that VCR-induced cytotoxicity was augmented by AAE through alteration of Bax, and Bcl-2 mRNA expression. Conclusion: Overall, owing to the nontoxic nature of AAE and its explicit role in enhancing VCR effectiveness, our study provided new insight into the development of a novel combinatorial approach in ALL using natural herbs. The practical implication of the research requires further investigation through clinical trials, opening avenues for forthcoming treatment improvements.

Investigating the Effect of Melissa Officinalis on After-Pains: A Randomized Single-Blind Clinical Trial.

Introduction: Regarding high prevalence of postpartum pain and side-effects of pharmaceutical analgesics on maternal and neonatal health, the present study aimed to explore the effect of Melissa officinalis on after-pain among mothers hospitalized in Asgariyeh Hospital, Isfahan, 2016. Methods: In this single-blind clinical trial, 110 women with moderate to severe after-pain were divided into two M.officinalis and mefenamic acid groups by random allocation. Samples in the first group received 250mg of mefenamic acid and the second group received 395mg of M.officinalis oral capsules every 6hours for 24hours following childbirth. The primary outcome (After-pain) was assessed using a numeric 10-point scale before intervention, 1,2 and 3hours after the first intervention and every 6hours to 24hours after delivery for each of second, third and fourth interventions. Data were analyzed, using SPSS by independent t-test, Mann-Whitney and chi-square test. Results: The demographic and obstetric variables and after-pain severity before the intervention in both groups were homogenous. Pain intensity wasn't significantly different between the two groups during first and second hours after the first intervention, but there was a significant difference in the third hour, The severity of pain was significantly different between the two groups in different assessments including: an hour after the second, third and fourth intervention (P<0.05). A significant difference was found between mefenamic acid and M.officinalis in pain relief. Conclusion: M.officinalis can reduce the severity of after-pain, because it eliminates the need for pharmaceutical analgesics and works much better than mefenamic acid.

Centaurea albonitens extract enhances the therapeutic effects of Vincristine in leukemic cells by inducing apoptosis.

Drug-induced toxicities and dose-related side effects are the major challenges in the conventional cancer therapy by the chemo drugs. On the other hand, herbal derivatives have obtained a great research interest in the field of therapeutic applications because of their more favorable specifications including less toxicity, cost-effective and more physiologically compatible than the chemical drugs. For this purpose, we evaluated methanolic extract prepared from Centaurea albonitens Turrill alone and in combination with Vincristine (VCR) for its potential cytotoxic effects in NALM-6, REH, NB4 and KMM-1 cell lines by using the various approaches. Centaurea genus is one of the current medicinal plants, which has used in traditional medicine, However, there are rare studies to examine its anticancer properties against hematologic malignant cells. In this study, we demonstrated Centaurea albonitens extract (CAE) induces cytotoxicity through G0/G1 phase arrest followed by apoptosis in a dose- and time- dependent manner, although with varying efficiency. Interestingly, normal cells didn't exhibit significant cytotoxicity after CAE treatment. Moreover, we found that low dose of CAE enhances anti-cancer effects of VCR in pre-B ALL cell lines (NALM-6 and REH). Further investigations validated synergistic anticancer activities of VCR and CAE through inducing apoptosis without significant cell cycle arrest. Taken together, our results demonstrated for the first time that the methanolic extract of Centaurea albonitens can be considered as a potential anticancer agent and/or an enhancer of chemotherapeutic sensitivity of VCR.

Traditional and modern aspects of hemorrhoid treatment in Iran: a review.

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.

Naghibione; A Novel Sesquiterpenoid with Antiplasmodial Effect from Dorema hyrcanum Koso-Pol. Root, a Plant Used in Traditional Medicine.

Some Dorema species are used in Persian traditional medicine. In the present study the total extract from the roots of Dorema hyrcanum Koso-Pol. was investigated for its in-vitro (pLDH assay) and in-vivo (Peters' 4-days suppressive test) antiplasmodial effects and assessed for cytotoxicity against the normal cell line MDBK (MTT test). The IC50 values for a chloroquine- sensitive (3D7) and a chloroquine- resistant (K1) strain of Plasmodium falciparum were 28.64 and 9.79 µg/mL, respectively. The inhibition percentage of the rodent parasite, Plasmodium berghei, on day 4 in mice was 77.9% and IC50 value on Madin-Darby bovine kidney cells (MDBK cells) was 59.84 µg/mL. The total extract was subjected to a bioassay-guided fractionation protocol based on the in-vivo model which resulted in the isolation of an acetophenon (compound 1), one new sesquiterpenoid; naghibione (compound 2) and two known sesquiterpenoid derivatives (compounds 3, 4). Their structures were elucidated by spectroscopic analysis, including 1D and 2D NMR experiments and ESI-MS. All compounds were evaluated for in-vivo antiplasmodial effect and the results revealed that naghibione showed good suppression activity, inhibiting 68.1 % of the parasite growth.

Antiplasmodial Activity and Cytotoxicity of Plants Used in Traditional Medicine of Iran for the Treatment of Fever.

Malaria is the most serious parasitic disease and one of the oldest recorded diseases in the world. Because of the resistance of malaria parasites to current drugs, it is necessary to discover new antiplasmodial drugs. Traditional medicine is one of the important sources of new antiplasmodial drugs. In this study, twenty methanolic extracts from different parts of sixteen medicinal plants used in traditional medicine of Iran for the treatment of "Nobeh fever" and/ or fever were screened for in-vivo antiplasmodial activity against Plasmodium berghei and cytotoxic effect on Madin-Darby bovine kidney cells (MDBK). Eleven species (55%) were found to have antiplasmodial activity. Methanolic extract from Rosa damascena Mill. reduced parasitemia by 57.7% compared to untreated control mice at intra-peritoneal (i.p.) injection doses of 10 mg/Kg per day for 4 days. This is the first report that mentioned in-vivo antiplasmodial activity of Rosa damascena Mill.

Hepatoprotective herbs, avicenna viewpoint.

BACKGROUND: Liver injury or dysfunction is considered as a serious health problem. The available synthetic drugs to treat liver disorders are expensive and cause further damage. Hence, hepatoprotective effects of some herbal drugs have been investigated, and one of the methods to choose herbs in order to study their biological effects is to search in ancient medical texts. Avicenna who is known as the prince of physicians had collected and classified Greek, Persian and Islamic medicine in the best possible way in the book of Canon in Arabic. OBJECTIVES: Avicenna's book of The Canon of Medicine was reviewed to find the hepatoprotective herbs. PATIENTS AND METHODS: Three different versions of the Canon were prepared and utilized. To find scientific names of plants we took advantage of three botany references. All of the herbs were investigated on the basis of scientific data from hepatoprotective effects point of view. The searched term was "hepatoprotective" without narrowing and limiting. The searched databases included Cochrane library, Web of science, SID, Irandoc and IranMedex. RESULTS: 18 plants were found. 85% of the presented species, genus or families of plants were reported to have hepatoprotective properties and in the remaining 15% there were no reports of hepatoprotective effect. Flowers and fruits were the most used part of the plants. Most of the plants had simultaneous protective effects on multiple organs but the protective effect on the liver was mostly accompanied by protective effect on the stomach (83%). The average temperament of these herbs is "hot" in the 2nd phase of the 2nd grade, and "dry" in the 3rd phase of the 2nd grade. Hepatoprotective herbs mostly prescribed as a part of hepatoprotective compound drugs formula or other formula for liver diseases are Crocus sativus, Pistacia lentiscus, and Cinnamomum spp. CONCLUSIONS: Maybe there is common mechanism for protecting both liver and stomach. Aquilaria agallocha, Aquilaria malaccensis, and Ruscus aculeatus whose hepatoprotective effects have not yet been reported are considered as good candidates for future investigations. Given that Crocus sativus, and Cinnamomum spp are used as flavors in most countries, they will be introduced for more investigation in order to produce hepatoprotective drugs.

Effects of fenugreek seed on the severity and systemic symptoms of dysmenorrhea.

BACKGROUND: Primary dysmenorrhea is a prevalent disorder and its unfavorable effects deteriorates the quality of life in many people across the world. Based on some evidence on the characteristics of fenugreek as a medical plant with anti-inflammato-ry and analgesic properties, this double-blind, randomized, placebo controlled trial was conducted. The main purpose of the study was to evaluate the effects of fenugreek seeds on the severity of primary dysmenorrhea among students. METHODS: Unmarried Students were randomly assigned to two groups who received fenugreek (n = 51) or placebo (n = 50). For the first 3 days of menstruation, 2-3 capsules containing fenugreek seed powder (900 mg) were given to the subjects three times daily for two consecutive menstrual cycles. Pain severity was evaluated using a visual analog scale and systemic symptoms were assessed using a multidimensional verbal scale. RESULTS: Pain severity at baseline did not differ significantly between the two groups. Pain severity was significantly reduced in both groups after the intervention; however, the fenugreek group experienced significantly larger pain reduction (p < 0.001). With respect to the duration of pain, there was no meaningful difference between the two cycles in the placebo group (p = 0.07) but in the fenugreek group, the duration of pain decreased between the two cycles (p < 0.001). Systemic symptoms of dysmenorrhea (fatigue, headache, nausea, vomiting, lack of energy, syncope) decreased in the fenugreek seed group (p < 0.05). No side effects were reported in the fenugreek group. CONCLUSION: These data suggest that prescription of fenugreek seed powder during menstruation can reduce the severity of dysmenorrhea.

Herbal Remedies Connected to Malaria like Fever in Iranian Ancient Medicinal Books- Brief Review Article.

Malaria is a major international public health problem. Drug-resistant parasites have made treatment and control of malaria more difficult. Therefore, safe, affordable and effective new drugs are urgently needed. Traditional medicine is an important source for new drugs. Determining the ancient medicinal books was the first step of this study for finding malaria or disease that has symptoms like malaria. Then the plants that used to treat "Ghebbe Khalesseh fever" were listed. Finally, recent antimalarial researches were explored. About 31 plants were identified. Information from these resources is valuable for the selection of plants for antiplasmodial screening programs.

In vitro and in vivo antimalarial evaluations of myrtle extract, a plant traditionally used for treatment of parasitic disorders.

Based on the collected ethnobotanical data from the Traditional Medicine and Materia Medica Research Center (TMRC), Iran, Myrtus communis L. (myrtle) was selected for the assessment of in vitro and in vivo antimalarial and cytotoxic activities. Methanolic extract of myrtle was prepared from the aerial parts and assessed for antiplasmodial activity, using the parasite lactate dehydrogenase (pLDH) assay against chloroquine-resistant (K1) and chloroquine-sensitive (3D7) strains of Plasmodium falciparum. The 4-day suppressive test was employed to determine the parasitemia suppression of the myrtle extract against P. berghei in vivo. The IC50 values of myrtle extract were 35.44 µg/ml against K1 and 0.87 µg/ml against 3D7. Myrtle extract showed a significant suppression of parasitaemia (84.8 ± 1.1% at 10 mg/kg/day) in mice infected with P. berghei after 4 days of treatment. Cytotoxic activity was carried out against mammalian cell lines using methyl thiazol tetrazolium (MTT) assay. No cytotoxic effect on mammalian cell lines up to 100 µg/mL was shown. The results support the traditional use of myrtle in malaria. Phytochemical investigation and understanding the mechanism of action would be in our upcoming project.

Ethnobotanical survey of herbal remedies traditionally used in Kohghiluyeh va Boyer Ahmad province of Iran.

ETHNOPHARMACOLOGICAL RELEVANCE: Medicinal plants are an important element of medical system. These resources are usually regarded as part of cultural traditional knowledge. We present for the first time the results of an ethnobotanical survey in Kohghiluyeh va Boyer Ahmad province of Iran, conducted between 2008 and 2010. This information could be the basis of an evidence based investigation to discover new drugs. MATERIALS AND METHODS: Ethnobotanical data were analyzed by use-reports in addition important indices like relative frequency of citation (RFC) and cultural importance index (CI) were calculated. Totally 23 informants were interviewed. RESULTS: Our study reports 138 traditionally used plant species, belonging to 52 plant families from this province. Asteraceae and Lamiaceae are the dominant locally used families. The highest number of species and application were reported for digestive system disorder, metabolic disorder and respiratory system, respectively. The part of the plant most frequently used was the aerial part (31.9%), leaves (14.8%) and fruits (11.7%). The plants are used both for medicinal and non-medicinal purposes. Daphne mucronata Royle. and Teucrium polium L. have the largest value of relative frequency of citation and cultural importance index, respectively. CONCLUSION: Kohghiluyeh va Boyer Ahmad has good ethnobotanical potential for medicinal plants. This study is the first contribution to the ethnobotany of this region. We have gathered from this province some considerable knowledge about local medicinal plants for treating common health problem that is ready to be further investigated in the laboratory.

Screening of antiplasmodial properties among some traditionally used Iranian plants.

ETHNOPHARMACOLOGICAL RELEVANCE: An investigation of plants was undertaken through interviews and literature surveys on plants used to treat malaria or cancer or microbial diseases in Iran. AIM OF STUDY: In vitro and in vivo antiplasmodial tests were carried out on selected plants traditionally used in Iran. MATERIALS AND METHODS: Thirty-two plants were extracted with methanol and tested for their in vitro (pLDH assay) activity against Plasmodium falciparum, in vivo activity against Plasmodium berghei and assessed for any cytotoxicity against the human cancer cell line MCF7 and the normal cell MDBK. RESULTS: Extracts from four plants, Buxus hyrcana Pojark. (Buxaceae), Erodium oxyrrhnchum M. Bieb. (Geraniaceae), Glycyrrhiza glabra L. (Fabaceae) and Ferula oopoda (Boiss and Bushe) Boiss. (Apiaceae) were found to have significant antiplasmodial activity (IC50 ranging from 4.7 to 26.6 microg/ml). These findings lend support to the use of Buxus hyrcana and Glycyrrhiza glabra in traditional medicine. The chloroformic fraction also was active against K1 and 3D7 strains. The chloroformic fraction was studied at 10 mg per kg body weight mouse per day. This fraction reduced parasitaemia by 86.1% compared to untreated control mice. CONCLUSION: Glycyrrhiza glabra showed antiplasmodial activity and has selectivity for Plasmodium falciparum and Plasmodium berghei when tested on mammalian cells. This is the first report that mentioned in vitro and in vivo antiplasmodial activity of Glycyrrhiza glabra.
