Effect of Nigella sativa L. seed oil on urinary incontinence and quality of life in menopausal women: A triple-blind randomized controlled trial.

Increased urinary incontinence is one of the most common changes during menopause. This study aimed to investigate the effect of Nigella sativa L. seed oil on urinary incontinence and quality of life (QoL) (primary outcomes) and sexual function (secondary outcome) in menopausal women. In this triple-blind randomized controlled trial, 60 women in Tabriz-Iran were equally allocated into two treatment and control groups using block randomization. The women applied 2-3 drops of Nigella sativa L. seed oil or placebo on their stomachs below the novel twice a day for 8 weeks. The data collection instruments were completed at baseline and just after the intervention. After intervention, the mean rank score of mixed urinary incontinence was significantly lower (p = .04) and the mean score of the incontinence-QoL was significantly higher (mean difference 12.63, 95% CI 2.33 to 22.93; p = .017) in the treatment group than the control group. However, there were no significant differences in stress incontinence, urge incontinence, sexual function, and menopause-specific QoL of women between the groups (p > .05). The results indicated the positive effect of the Nigella sativa L. seed oil on mixed incontinence and incontinence-QoL; nevertheless, to make a certain conclusion, further studies are required.

Effect of an herbal capsule on chronic constipation among menopausal women: A randomized controlled clinical trial.

OBJECTIVE: Chronic constipation is frequently observed in postmenopausal women. An herbal combination including clover plants, Roman anis or Anisone, green anis or fennel, green raisins, Alhagi maurorum, violets, Terminalia chebula, senna and golqand has been introduced in traditional books as an effective laxative. Thus, the present study aimed to assess the effectiveness of the combined herbal capsule on chronic constipation in postmenopausal women. MATERIALS AND METHODS: This triple blinded, randomized placebo-controlled trial was conducted on 64 postmenopausal women. Individuals were randomly assigned to combined the herbal capsule and placebo groups. The herbal capsule included cloves (4 units), Anise and Anison (6 units each), violet flowers (12 units), Terminalia Chebula and fresh green raisins (25 units each), senna leaves, Alhagi maurorum, and Golqand (50 units each). Constipation questionnaire and the individual's assessment of constipation symptoms scale were used for data collection. RESULTS: The mean frequency of bowel movements in the herbal capsule group was significantly higher than the placebo group (mean difference=4.2; 95% confidence interval: 0.3 to 4.5; p<0.001). Straining during defecation, stool amount, incomplete defecation, sensation of obstruction during defecation, and need for manipulation to facilitate removal of stools were significantly reduced in the herbal capsule group compared to the placebo group (p<0.001). The amount and consistency of defecation was also improved in the two study groups, but a significant difference was observed between the groups (p<0.001). The mean score of constipation symptoms in the herbal capsule group was significantly reduced compared to the placebo group (-15.4; -11.5 to -19.29; p<0.001). CONCLUSION: Consumption of herbal capsules improved chronic constipation in postmenopausal women.

Biological Activities and Phytochemical Study of Pedicularis wilhelmsiana Fisch Ex. From Iran.

This research paper presents findings of an investigation about antibacterial effect of methanol/water fractions as well as cytotoxic activity of the extracts obtained from Pedicularis wilhelmsiana (Scrophulariaceae) which grows in Azarbaijan/Iran by agar well diffusion method and brine shrimp lethality test successively. Phytochemical study of this plant was determined as well. A combination of solid-phase extraction (SPE), preparative reversed-phase HPLC analysis and spectroscopic means were applied for fractionation, purification, and identification of ingredients respectively. Antimicrobial test demonstrated that 40% and 60% methanol/water fractions were more active than methanolic extract and other SPE fractions. No cytotoxic effect was detected from the extracts of this plant by brine shrimp lethality assay. Phytochemical study of aerial parts of Pedicularis wilhelmsiana (P. wilhelmsiana) afforded two phenylethanoids (verbascoside and martynoside), three iridoids (Aucubin, ipolamiid, 5-hydroxy-8-epi-loganin) and two flavonoids (luteolin, luteolin-7-glucoside) along with mannitol on the basis of spectral evidences (UV, 1H and 13CNMR) as well as comparison with literature data. The findings of this research supported further studies related to antibiotic potential of methanolic extract of P. wilhelmsiana.

Evaluation of Herbal Mouthwashes Containing Zataria Multiflora Boiss, Frankincense and Combination Therapy on Patients with Gingivitis: A Double-Blind, Randomized, Controlled, Clinical Trial.

BACKGROUND: Dental plaques as adhesive microbial aggregates on tooth surfaces are considered the first stage of tooth decay as well as gingivitis. Accordingly, the effect of different antimicrobial mouthwashes on removing dental plaques and preventing their formation has been evaluated in various studies. This study aimed to evaluate the efficacy of herbal mouthwashes containing hydro-alcoholic extract of Zataria multiflora (ZM), Frankincense (FR), and a combination of both (ZM+FR) and compare it with chlorhexidine (CHX) mouthwash in subjects with gingivitis. MATERIALS AND METHODS: In this randomized, controlled, clinical trial a total of 140 patients with gingivitis were divided into four groups including CHX (control group), ZM, FR, and ZM+FR groups. Plaque index (PI), gingival index (GI), and gingival bleeding index (GBI) were measured in days 1, 14, and 21. RESULTS: All three herbal types of mouthwash significantly improved plaque, gingivitis, and gingival bleeding throughout days 14 to 21 (P<0.001). There was no difference between herbal mouthwash with CHX groups. CHX mouthwash showed the most side effects (54.3%), while ZM mouthwash showed the least side effects and the highest consumer satisfaction (5.7% and 94%, respectively). CONCLUSION: All of the herbal mouthwashes can be good candidates for controlling gingivitis. Comparing with CHX mouthwash, herbal mouthwashes have lower side effects and negligible alcohol content. Among the herbal mouthwashes, ZM outperforms FR and FR+ZM due to its lower side effects and higher levels of patients' satisfaction.

The effect of Rosa (L. Rosa canina) on the incidence of urinary tract infection in the puerperium: A randomized placebo-controlled trial.

Urinary tract infection (UTI) is an infection that can occur in any area of the urinary tract which is characterized by a positive urine culture (U/C). The risk of UTI following cesarean section (CS) increases due to procedures such as catheterization. In vitro studies have demonstrated the effect of Rosa canina fruit in preventing Escherichia coli growth. This study was conducted to determine the effect of R. canina fruit in preventing the incidence of UTI in women following CS. This triple-blind randomized clinical trial was conducted in 2016 on 400 women following CS with negative U/C in Alzahra and Taleghani educational hospitals in the city of Tabriz-Iran. Participants were assigned into two groups of 200 women using block randomization. Each group received a twice daily dose of 500 mg capsules containing R. canina or placebo from the second day after CS for 20 days. Women were assessed by U/C on the 7th-10th and 20th days following CS. UTI was significantly lower in the intervention group compared with the control in the follow-ups conducted on the 7th-10th days (odds ratio = 0.22; confidence interval 95% [0.07, 0.67]; p = .006) and 20th day (odds ratio = 0.32; confidence interval 95% [0.14, 0.75]; p = .008). But the incidence of cystitis in the two groups was not statistically significant (p > .05). R. canina fruit capsules were able to reduce the incidence of UTI after CS. Thus, it is likely that administration of this medication can promote maternal health following CS.

Phenolic Derivatives of Artemisia Spicigera C. Koch Growing in Iran.

This study aimed to determine phenolic compounds of Artemisia spicigera (family Asteraceae) growing in East-Azarbaijan province of Iran. 20%, 40 % and 60% SPE fractions of methanolic extract of A. spicigera, were subjected to reversed phase preparative HPLC, with the mobile phase consisted of methanol and water. Structural identification of phytochemicals by spectroscopic methods including UV and NMR spectroscopy, yielded 4, 6-di methoxy acetophenone-2-O-ß-D-glucopyranoside from 20%, 5-methoxyluteolin 7-O-ß-D-glucopyranoside, luteolin and chrysoeriol 7-O-ß-D-glucopyranoside from 40% and 5-methoxy luteolin from 60% SPE fractions. Although within identified pure compounds, luteolin was the only phenolic reported from some other species of Artemisia, but occurrence of remained identified phenolics in this study, was firstly reported from Artemisia genus. Further phytochemical investigations were proposed in order to isolate some other active fractions and pure compounds.

Ginger from ancient times to the new outlook.

CONTEXT: Ginger is the rhizome of Zingiber officinale, a perennial plant, used alone or in compounds as a spice or remedy in ancient recipes of Iranian traditional medicine (ITM) as an effective tonic for the memory and digestive system, the opener of hepatic obstructions, aphrodisiac, for expelling compact wind from stomach and intestines, diluting, desiccating and emollient of phlegmatic and compact humor sticking to body organs, stomach, intestine, brain and throat. The ITM scholars believed that ginger was a vermifuge as well as a remedy for paralysis and obstructive jaundice. They also revealed that this phytomedicine cures diarrhea due to corrupted food. This study aimed to compare the medicinal properties (afaal) of ginger in ITM with those indicated in modern research. RESULTS: Results of this study showed that the modern phytotherapy confirmed some of the properties of ginger. In addition, some of the properties of this phytomedicine have not been studied yet. CONCLUSIONS: By studding the ITM literature, herb elements or in other words ITM keywords, researchers can predict and state some unknown or less known potential pharmacologic effects of medicinal plants.

Biological Activity and Phytochemical Study of Scutellaria platystegia.

This study aimed to determine biological activity and phytochemical study of Scutellaria platystegia (family Labiatae). Methanolic (MeOH) extract of aerial parts of S. platystegia and SPE fractions of methanolic extract (specially 20% and 40% methanolic fractions), growing in East-Azarbaijan province of Iran were found to have radical scavenging activity by DPPH (2, 2-diphenyl -1- pycryl hydrazyl) assay. Dichloromethane (DCM) extract of this plant exhibited animalarial activity by cell free method providing IC50 at 1.1876 mg/mL. Crude extracts did not exhibit any toxicity assessed by brine shrimp lethality assay. Phytochemical study of methanolic extract by using reverse phase HPLC method and NMR instrument for isolation and identification of pure compounds respectively, yielded 2-(4- hydroxy phenyl) ethyl-O-ß-D- glucopyranoside from 10% and apigenin 7-O-glucoside, verbascoside and martynoside from 40% SPE fraction. Occurance of verbascoside and martynoside as biochemical markers appeared to be widespread in this genus. Antioxidant and antimalarial activity of MeOH and DCM extracts, respectively, as well as no general toxicity of them could provide a basis for further in-vitro and in-vivo studies and clinical trials to develop new therapeutical alternatives.

Herbs and hazards: risk of aristolochic acid nephropathy in Iran.

Herbs are usually considered as inherently harmless products. Nonetheless, various renal injuries have been reported in association with several herbs. The best-known herb-induced chronic kidney disease is aristolochic acid nephropathy. Aristolochic acid is found in Chinese slim herbs. Balkan endemic nephropathy is nowadays considered as an aristolochic acid nephropathy. Plants of Aristolochiaceae (also known as birthwort, dutchman's pipe, and somersworth) is named zaravand or chopoghak in Persian and it grows in different mountainous and rural areas of Iran. The fruit and the steam of the Aristolochiacae are named zaravand gerd (nokhod alvand) and zaravand dearaz, respectively, and have different usage in Iranian teadirional such as treatment of headache, back pain, and anxiety. Some patients with end-stage renal disease and bilateral small kidneys have a history of exposure to some herbal remedies. We need to consider the possibility of environmental toxins and even Aristolochia nephrotoxicity as a potential danger in Iran.

Phytochemistry and bioactivity of Pedicularis sibthorpii growing in Iran

The methanol extract of the aerial parts of the medicinal plant Pedicularis sibthorpii Boiss., Scrophulariaceae, growing in the Azerbaijan province of Iran, was found to be active in the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and the antibacterial agar well diffusion assays, but no general toxicity was observed in the brine shrimp lethality assay. A combination of solid-phase extraction (SPE) and preparative reversed-phase high-performance liquid chromatography (prep-RP-HPLC) analyses of the methanolic extract afforded three phenylethanoids (verbascoside, martynoside and isomartynoside), an iridoid (aucubin), a flavonoid (luteolin 7-O-β-D-glucopyranoside) and mannitol, and the structures of these compounds were elucidated unambiguously by spectroscopic means. The distribution of the isolated compounds within the genus Pedicularis has also been discussed.

Antioxidant and Antimicrobial activity of Pedicularis sibthorpii Boiss. And Pedicularis wilhelmsiana Fisch ex.

PURPOSE: This research paper presents antioxidant and antimicrobial activities of Pedicularis sibthorpii and Pedicularis wilhelmsiana which grow in Azerbaijan/Iran with claimed a lot of therapeutic effects. METHODS: DPPH assay and agar well diffusion method were carried out to determine antioxidant and antimicrobial activities respectively. RESULTS: Methanolic extract showed better antioxidant activity compared to other crude extracts (n-hexane and dichloromethane). Methanolic extracts of both Pedicularis sibthorpii and Pedicularis wilhelmsiana were found to have antibacterial activity especially against gram positive strains of S. ureus, S.epidermidis. No antifungal activity was observed in the tested extracts. CONCLUSION: Existence of some phenolic compounds in methanolic extracts, such as phenylethanoids and flavonoids (found in other species of Pedicularis), which cause both antioxidant and antibacterial activities, is probable. Antimicrobial and antioxidant activity of the methanolic extracts supports further studies related to phytochemical investigation and bioassay of different fractions to isolate pure compounds of plants.

Antioxidant, total phenol and flavonoid contents of two pedicularis L. Species from eastern azerbaijan, iran.

INTRODUCTION: Pedicularis sibthorpii and P. wilhelmsiana are endemic species mainly found in North-West of Iran. Plants of genus Pedicularis produce some important poly-phenols and flavonoids. In the present work, total phenol and flavonoid contents of the mentioned species as well as their antioxidant capacity have been evaluated. METHODS: Methanol extract of samples was fractionated by SPE method using an ODS cartridge and their (1)H-NMR spectra were recorded. Total phenols and flavonoids of methanol extracts were determined using Folin- Ciocalteu and aluminum chloride methods. For determining antioxidant activity of the extracts and fractions, bleaching of purple color methanol solu-tion of 1, 1-diphenylpycryl hydrazyl (DPPH) was measured by spectrophotometric assay. RESULTS: Total phenols of Pedicularis sibthorpii and P. wilhelmsiana were in the range of 8-30 mg g(-1) and 9-20 mg g(-1), respectively. The 40% and 60% fractions of P. sibthorpii and the 20%, 40% and 60% fractions of P. wilhelmsiana showed higher amounts of phenolic compounds. The total flavonoid contents of P. sibthorpii and P. wilhelmsiana were in the range of 0-215 mg g(-1) and 0-177 mg g(-1), respectively, whereas the 40% and 60% fractions showed higher flavonoid amounts. Antioxidant activity of P. sibthorpii and P. wil-helmsiana were in the range of 0.01-0.7 mg mL(-1) and 0.01-1.02 mg mL(-1). In the same manner, the 20% and 40% fractions of P. sibthorpii and the 40% and 60% fractions of P. wilhelmsiana had lower RC50 than that of other fractions. CONCLUSION: Fractions with lower RC50 had higher contents of phenolic and flavonoid compounds. The results of NMR spectra were parallel with these findings and show that it is worth to do phytochemi-cal studies on P. sibthorpii and P. wilhelmsiana.
