Mentha longifolia syrup in secondary amenorrhea: a double-blind, placebo-controlled, randomized trials

The Effect of Metabolic Persian Diet on Ovulation Induction in Infertile Women

Introduction

Infertility is an important issue with a high social and psychological burden. From the perspective of Persian Medicine (PM), uterine cold temperament is one of the important causes of female infertility.

Aim

The aim of this study was to study the effect of PM or Iranian traditional medicine on improving ovulation and fertility.

Methods

From January 2017 to August 2017, sixty infertile women with eugonadotropic ovulation disorder were randomly divided into two groups. Both groups were treated with clomiphene citrate, except that the intervention group also received metabolic Persian diet (MPD). In each cycle, the dominant follicles and endometrium were investigated with ultrasound. At the end of the cycle, beta human chorionic gonadotropin (β-HCG) was evaluated and if positive, another ultrasound was performed two weeks later to confirm early pregnancy.

Results

The number of dominant follicles from the first to third cycle increased from 2.15 ± 1.14 to 2.28 ± 0.61 in the intervention group and decreased from 1.86 ± 0.79 to 1.30 ± 0.47 in the control group. The dominant follicle size changed from 16.00 ± 4.08 to 18.78 ± 2.78 and from 15.05 ± 3.11 to 15.80 ± 3.89 in the intervention and control groups, respectively. But endometrial thickness did not change significantly in the intervention group. Pregnancy results based on β-HCG and ultrasound findings were positive in 19 and 16 patients in the intervention group and in 10 and 7 patients in the control group, implying significantly higher numbers in the first group.

Conclusion

It seems that MPD may be effective in the success of ovulation induction.

Evaluation of general body temperament and uterine dystemperament in amenorrhoea: a cross-sectional analytical study

OBJECTIVES

Amenorrhoea in women of reproductive age may be an indication of an undiagnosed and chronic condition. The concept of temperament is a fundamental component of health preservation and diagnosis of various disease conditions including amenorrhoea in Unani medicine. Dystemperament is the commonest cause of various diseases. Therefore, general body temperament and uterine dystemperament in amenorrhoea was determined.

METHODS

A prospective, single-centre, cross-sectional observational study from June to November 2019 was conducted in 80 patients of reproductive age with amenorrhoea ≥60 days. Validated questionnaire for the assessment of women's general body temperament and clinical features of uterine dystemperament was used. The data were analysed by appropriate statistical analysis.

RESULTS

The age of patients with amenorrhoea ranged from 14 to 50 years. The most prevalent general body temperament was cold (57.5%) and wet (60%). Cold and wet general temperament was more common at the age of 21-30 years (30 and 36.25%), 60-90 days of amenorrhoea (33.75 and 32.5%) and body mass index (BMI) ≥25 kg/m² (47.5 and 50%). The most prevalent uterine dystemperament was cold and dry (95%). A significant correlation between general temperament with age, amenorrhoea and BMI >23 kg/m² was noted. Moreover, the cold temperament of the body had a significant correlation with cold uterine temperament (r=0.864, p<0.001).

CONCLUSIONS

This study corroborated the claim of Unani scholars that cold and wet general and uterine temperament is more common in amenorrhoea and obesity. However, amenorrhoea can also occur in normal and other temperaments.

A double-blind, randomized pilot study for comparison of Melissa officinalis L. and Lavandula angustifolia Mill. with Fluoxetine for the treatment of depression

Background

Depression has rapidly progressed worldwide, and the need for an efficient treatment with low side effect has risen. Melissa officinalis L and Lavandula angustifolia Mill have been traditionally used in Asia for the treatment of depression. Many textbooks of traditional Persian medicine refer to these herbs for the treatment of depression while there are no adequate clinical trials to support this claim.

The present study aimed to evaluate the efficacy of M. officinalis and L. angustifolia compared to fluoxetine for the treatment of mild to moderate depression in an 8-week randomized, double-blind clinical trial.

Methods

Forty-five adult outpatients who met the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) for major depression, were randomly assigned to 3 groups to daily receive either M. officinalis (2 g) or L. angustifolia (2 g) or fluoxetine (20 mg) and were assessed in weeks 0, 2, 4 and 8 by the Hamilton Rating Scale for Depression (HAM-D) including 17 items.

Results

Our study showed that M. officinalis and L. angustifolia effect similar to fluoxetine in mild to moderate depression. (F = 0.131, df = 2,42, p = 0.877).

Conclusion

Due to some restrictions in this study including absence of placebo group, large-scale trials are needed to investigate the anti-depressant effect of these two herbs with more details.

A comprehensive review of clinical studies with herbal medicine on polycystic ovary syndrome (PCOS)

BACKGROUND

Polycystic ovary syndrome (PCOS) is a frequent medical condition characterized by both metabolic and reproductive disorders. Different pharmaceutical treatments have been proposed for PCOS. However, side effects of long-term treatments and their probable low efficacy have made complementary and alternative treatments a valuable option. Recent reports have indicated the increased use of complementary treatments. Herbal medicine, as part of complementary medicine, was find introduced in traditional Persian and Chinese medicine. Medicinal herbs have used for a long time in the treatment of gynecological and infertility problems of PCOS patients. In this study, we aimed to review herbal medicines used for PCOS worldwide.

METHODS

PubMed, Embase, Cochrane, and Scopus databases were searched for clinical trials and Randomized Controlled Trials based on related keywords. Data were collected from 1990 to 2019.

RESULTS

According to a multitude of studies, a wide spectrum of herbs can be used to improve various aspects of PCOS. Herbs such as Cinnamomum verum, Trigonella foenum-graecum L., and Vitex agnus-castus can impact on menstrual and ovulatory dysfunctions, obesity, insulin resistance, lipid-metabolism dysfunction, and androgen excess-related conditions.

CONCLUSION

Some plants as natural remedies may have beneficial effects on improving different aspects of PCOS; but further studies are needed to investigate their mechanisms and safety.

Uterine epilepsy: a historical report from Avicenna's point of view

OBJECTIVE

Epilepsy is a common neurological disorder, the history of which dates back to thousands of years ago. Avicenna (980-1037 AD) is a famous Persian scholar who considered different types of epilepsy and their specific treatments. His book Al-Qanun fi al-Tibb was taught in Europe for several years. Along with explaining the diseases occurring in various body organs, the book describes neurological and neuropsychological conditions such as epilepsy METHODS: This article is a review of the book Al-Qanun fi al-Tibb and some of the traditional Persian medicine sources, including Kāmil al-Sināa al Tibbiya and Makhzan-O-L Advieh, on uterine epilepsy, its etiology, clinical manifestations and treatments. Also, articles related to this topic in the field of traditional Persian medicine or historical articles have been searched for in Google Scholar search engine or PubMed database.

RESULTS

Avicenna categorizes the causes of epilepsy into two main groups: those caused by brain diseases and those associated with the diseases of other organs. He believed that the stomach, the spleen, the maraqq, the uterus, or other body organs influence the brain and can cause epilepsy. In uterine epilepsy, the primary pathology lies with the uterus and can affect the brain. This condition occurs due to the retention of the menses or semen.

CONCLUSION

In this historical article, we intend to explain Avicenna's viewpoint on uterine epilepsy. We suggest further studies on this topic, for example, to evaluate the frequency of epilepsy in patients with the retention of the menses or the semen.

The comparison of fennel infusion plus dry cupping versus metformin in management of oligomenorrhoea in patients with polycystic ovary syndrome: a randomised clinical trial

Oligomenorrhoea treatment with hormone therapy and Metformin is not usually well tolerated and is associated with a broad range of side effects. In Persian medicine, the management of oligomenorrhoea can be done with fennel and dry cupping. A clinical trial was conducted on 61 patients with oligomenorrhoea. The patients randomly received treatment for 6 months in two groups: fennel infusion plus dry cupping (Group A); versus treatment with Metformin (Group B). On the days between the two periods, the patients' BMI, pain levels and side effects were assessed. Thirty-one patients (mean age: 26.68) in Group A, and 30 patients (mean age: 28.90) in Group B were enrolled. The mean numbers of days between the two periods after 3 and 6 months in Group A was, respectively, 32.59 and 30.69, versus 40.66 and 431.22 in Group B. The mean pain severity dropped significantly in Group A. Fennel seed infusion plus a dry cupping uses a safe and effective therapeutic intervention in the management of oligomenorrhoea. IMPACT STATEMENT What is already known on this subject? Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women. Some common clinical manifestations of this syndrome include menstrual disorders such as oligomenorrhoea and amenorrhoea. The recommended therapeutic interventions include oral intervention, as well as metformin, which are associated with an increased risk of vascular thromboembolism, digestive complications such as nausea, and dizziness, and vitamin B12 deficiency. Therefore, the use of complementary medicine in controlling and treating PCOS is considered a valuable intervention in conventional medicine. In Persian traditional medicine, medicinal fennel (with the scientific name of Foeniculum Vulgare Mill) is commonly used in this regard. The practice of dry cupping during the monthly period that ends with ovulation is also recommended. What do the results of this study add? The present study concludes that fennel seed infusion plus a dry cupping therapy is effective and safe in reducing the days between two menstrual periods and manages oligomenorrhoea. What are the implications of these findings for clinical practice and/or further research? A clinical study is suggested for assessing the effect of fennel seed infusion plus dry cupping on oligomenorrhoea, with a large sample size and a longer follow up time.

Modulation of in vitro proliferation and cytokine secretion of human lymphocytes by Mentha longifolia extracts

OBJECTIVE

Mentha longifolia L. Hudson has been used in folk medicine for various purposes especially for its anti-inflammatory effects. Lymphocytes play a central role in development of inflammation. In the present study, we investigated the immunomodulatory effects of different extracts of M. longifolia on human peripheral blood lymphocytes (PBLs), as main players in development of inflammation.

MATERIALS AND METHODS

PBLs stimulated with phytohemagglutinin (PHA) were cultured in the presence of the plant extracts. The effects of the extracts on activation of cells were determined by BrdU assay. The viability of cells was examined by flow cytometry using propidium iodide staining. Also, IFN-γ (T helper 1, TH1) and IL-4 (TH2) secretion was measured by ELISA.

RESULTS

Except for the water extract which had a weak inhibitory effect, treatment of cells with more than 1μg/ml of butanol, hexane, ethyl acetate and dichloromethane extracts resulted in strong inhibition of cells proliferation (IC₅₀ 4.6-9.9 µg/ml). Flow cytometry analysis showed that these extracts at ≤10μg/ml were non-cytotoxic. Dichloromethane and ethyl acetate extracts at 10 μg/ml decreased IFN-γ production in a dose-dependent manner from 919±91.1 pg/ml in PHA-only-treated cells to 568±22.6 pg/ml (in dichloromethane-treated cells) and 329±12.3 pg/ml (in ethyl acetate-treated cells) (p<0.001). At 10 μg/ml, the ethyl acetate extract increased IL-4 secretion compared to PHA-only-treated cells (p<0.05). The hexane extract decreased IFN-γ level but did not affectIL-4 production.

CONCLUSION

Reduction of IFN-γ and augmentation of IL-4 secretion induced by the extracts suggested the potential of M. longifolia to inhibit TH1 inflammatory responses toward a TH2 dominant response.

Assessing the effect of Mentha longifolia essential oils on COX-2 expression in animal model of sepsis induced by caecal ligation and puncture

CONTEXT

Mentha longifolia L. (Lamiaceae), a traditional Iranian plant, possesses antimicrobial and antioxidant activities.

OBJECTIVE

We investigated the potential protective effects of M. longifolia essential oils (E.Os) on caecal ligation and puncture (CLP) induced liver injury.

MATERIALS AND METHODS

Wistar Albino rats (n = 50) were grouped as follows: (1) a laparotomy group (LAP); (2) a CLP group (CLP); (3) the treatment groups received orally the E.Os (50 and 100 mg/kg b.w) and indomethacin (2 mg/kg b.w) for 2 weeks. The oxidative stress parameters, liver enzymes and prostaglandin E2 (PGE2) level were measured in liver and plasma tissues. The liver was also harvested for the real time PCR of cyclooxygenase (COX-2) expression following histopathological examinations.

RESULTS

The results indicated that the CLP operation significantly increased lipid peroxidation (LP) [1.79-fold], myeloperoxidase (MPO) [2.76-fold], PGE2 [1.56-fold] besides plasma aspartate aminotransferase (AST) [2.4-fold] and alanine aminotransferase (ALT) activities [2.22-fold], while, markedly reduced glutathione (GSH) [0.63-fold] and ferric reducing ability of plasma (FRAP) levels [0.63-fold]. Even COX2 expression significantly increased in the CLP group as compared to the LAP group. Treatments of rats with the E.Os could return all the hepatic and plasma biomarkers to the normal levels. These results were further confirmed by pathological examination on liver indicating that E.Os could successfully improve the CLP-induced liver injuries.

DISCUSSION AND CONCLUSIONS

Our findings suggest that E.Os is able to protect liver injuries against sepsis via modulating the oxidative stress parameters concomitant with the suppression of inflammatory reactions such as PGE2 and COX-2.

Efficacy of a Herbal Formulation Based on Foeniculum Vulgare in Oligo/Amenorrhea: A Randomized Clinical Trial

BACKGROUND

The aim of this study was to evaluate the efficacy of the herbal tea based on Foeniculum vulgare, on inducing regular bleeding in women with oligomenorrhea and secondary amenorrhea( oligo/amenorrhea).

METHODS

Forty women aged 18- 40 with oligo/amenorrhea were enrolled in this randomized controlled clinical trial and were allocated to two groups equally. The women in the first group were treated by Fomentex (Foeniculum vulgare / Mentha longifolia / Vitex agnus-castus) herbal tea 11.2 g/day in 2 divided doses for 2 weeks and the second group were treated by medroxy progesterone acetate (MP)10 mg/day for the last 10 days of their menstrual cycles. The intervention was repeated in three cycles of menstruation in both groups. Bleeding pattern was documented by the patient on diary cards. The occurrence (yes/no) of bleeding, the regularity of bleeding pattern, the interval of cycles, the duration of bleeding, the volume of blood flow, the hormonal parameters (total testosterone, free testosterone luteinizing hormone and follicle-stimulating hormone), and the endometrial thickness in sonography before and after the intervention were evaluated and compared as outcomes.

RESULTS

The number of women with bleeding during the first cycle was in the Fomentex group and the MP group 83.3% and 94.1% respectively (p = 0.61). The regularity of bleeding did not significantly differ in patients treated with Fomentex from those given MP (66.7% vs. 94.1%; p = 0.088). Mean interval of cycles decreased in both groups after intervention (P<0.001). Mean duration decreased significantly in MP group after the intervention but it was not different in patients treated with Fomentex. The difference between 2 groups was not significant (P=0.705). Volume of blood flow, with regard to Pictorial Blood Assessment Chart (PBAC), increased significantly in MP group after the intervention (P=0.001) and it was not different in patients treated with Fomentex (P=0.757); however, difference between 2 groups was not significant (P=0.063). The percentage of patients with on time menstruation in the next (drug-free) episode, was higher in the Fomentex group compared with the MP group (50% vs. 23.5%; p = 0.105). Secondary outcomes such as dysmenorrhea, acne and hirsutism reduced in the Fomentex group (P≤0.05), while they increased in the MP group (P=0.007). At the end of the treatment, there was a significant decrease in luteinizing hormone, total testosterone and free testosterone in patients taking Fomentex. The decrease of endometrial thickness, was significant in both groups after the intervention (P=0.001), but the difference between 2 groups was not significant (P=0.58). No notable complication or side effect was reported in relation to Fomentex.

CONCLUSION

Fomentex herbal tea is a safe, well-tolerated, and effective choice in inducing bleeding and maintaining regular bleeding in women with oligo/amenorrhea.

Mentha longifolia alleviates experimentally induced angina via decreasing cardiac load

Angina occurs due to imbalance between heart oxygen demand and supply and is associated with serious morbidity and mortality. Here, the possible antianginal effect of Mentha longifolia extract was studied in experimental model of angina. Aerial parts of M. longifolia were extracted, standardized, and given to rats three days before angina. Heart hemodynamics and conductivity were recorded by microtip catheter and surface electrodes. M. longifolia extract significantly alleviated the sustained decline in cardiac contractility after vasopressin exposure. However, M. longifolia did not affect the impaired cardiac dilation after vasopressin. Heart rate was significantly decreased after vasopressin exposure in rats treated with M. longifolia compared with untreated animals. In addition, M. longifolia produced more increase in systolic and diastolic durations after vasopressin exposure compared with untreated animals. Moreover, the plant extract alleviated the ST height changes during vasopressin injection. M. longifolia extract alleviates impaired cardiac function associated with angina through decreasing heart work. PRACTICAL APPLICATIONS: The present study is the first to study the effect of M. longifolia in an experimental model of angina. M. longifolia alleviated the impaired cardiac contractility associated with angina exposure. The antianginal effect of M. longifolia could be through reducing cardiac load. This can be concluded from the decrease in heart rate and the systolic and diastolic cycles elongation after exposure to vasopressin in animals pretreated with M. longifolia. This helps in reducing the associated cardiac ischemia upon exposure to vasopressin as indicated by ST change. This could provide new directions in the management of the serious angina disease.

Herbal Medicine for Oligomenorrhea and Amenorrhea: A Systematic Review of Ancient and Conventional Medicine

Introduction

Menstrual bleeding cessation is one of the most frequent gynecologic disorders among women in reproductive age. The treatment is based on hormone therapy. Due to the increasing request for alternative medicine remedies in the field of women's diseases, in present study, it was tried to overview medicinal plants used to treat oligomenorrhea and amenorrhea according to the pharmaceutical textbooks of traditional Persian medicine (TPM) and review the evidence in the conventional medicine.

Methods

This systematic review was designed and performed in 2017 in order to gather information regarding herbal medications of oligomenorrhea and amenorrhea in TPM and conventional medicine. This study had several steps as searching Iranian traditional medicine literature and extracting the emmenagogue plants, classifying the plants, searching the electronic databases, and finding evidences. To search traditional Persian medicine references, Noor digital library was used, which includes several ancient traditional medical references. The classification of plants was done based on the repetition and potency of the plants in the ancient literatures. The required data was gathered using databases such as PubMed, Scopus, Google Scholar, Cochrane Library, Science Direct, and web of knowledge.

Results

In present study of all 198 emmenagogue medicinal plants found in TPM, 87 cases were specified to be more effective in treating oligomenorrhea and amenorrhea. In second part of present study, where a search of conventional medicine was performed, 12 studies were found, which had 8 plants investigated: Vitex agnus-castus, Trigonella foenum-graecum, Foeniculum vulgare, Cinnamomum verum, Paeonia lactiflora, Sesamum indicum, Mentha longifolia, and Urtica dioica. Conclusion. Traditional Persian medicine has proposed many different medicinal plants for treatment of oligomenorrhea and amenorrhea. Although just few plants have been proven to be effective for treatment of menstrual irregularities, the results and the classification in present study can be used as an outline for future studies and treatment.

The medieval Persian manuscript of Afyunieh: the first individual treatise on the opium and addiction in history

According to historical evidence, the abuse of opium has been reported all over the globe-specifically throughout Eastern nations-since the sixteenth century. Before that, opium had mostly been applied as medication. Reference has been made in traditional Persian medical literature to the method of cultivation, properties, side effects and toxicity. In sixteenth century Iran, during the reign of the Safavids, opium abuse began. It was from then that prominent Persian scholars started to think of solutions to this societal problem. One of the most famous scholars was Imad al-Din Mahmud ibn Mas'ud Shirazi, who composed a book concerning addiction-Afyunieh, a comprehensive book on the topic of opium and all issues of opium. Furthermore, he recommended methods for reducing opium dose as well as substitution with other medications that had a narrower range of side effects, in order to eradicate dependency upon opium and opium-derived materials. This is most likely the first book that comprehensively addressed opium and discussed drug rehabilitation methodology, in traditional Persian medical literature. In this historical review, the authors have introduced the book Afyunieh, which presents methods for treating addiction to and giving up opium; the text comprises a synthesis of the author's opinions, professional experience and references to the work of other famous physicians.

Effect of Melissa officinalis (Lemon balm) on Sexual Dysfunction in Women: A Double- blind, Randomized, Placebo-controlled Study

Hypoactive sexual desire disorder (HSDD) is the most prevalent female sexual dysfunction (FSD) and its bio-psychosocial multifactorial etiology justifies its multifaceted treatment. In Persian Medicine (PM), the weakness of the main organs (heart, brain and liver) is one of the important causes of lack of sexual desire; hence, their strengthening is a priority during treatment. Melissa officinalis is one of the medicinal plants with tonic characteristics for the main organs in PM and was used for treatment in this study. The aim of the present study was to evaluate the efficacy and safety of M. officinalis in the improvement of HSDD in women. Eighty nine (89) eligible women suffering from decreased sexual desire were randomly assigned to groups. The participants received medication (500 mg of aqueous extract of M. officinalis) or placebo 2 times a day for 4 weeks. Changes in scores of desire, arousal, lubrication, orgasm, satisfaction and pain were evaluated at the end of 4 weeks of treatment using the Female Sexual Function Index (FSFI) questionnaire in the two groups. Forty three participants completed the study. The increase in desire (P < 0.001), arousal (P < 0.001), lubrication (P < 0.005), orgasm (P < 0.001), satisfaction (P < 0.001), pain (P < 0.002) and FSFI total score (P < 0.001) in the M. officinalis group was significantly more than that of the placebo group. The willingness to continue treatment was significantly higher in the M. officinalis as compared to the placebo group (P < 0.001). M. officinalis may be a safe and effective herbal medicine for the improvement of HSDD in women.

Traditional Persian Medicine and management of metabolic dysfunction in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. Its cause is unknown and it remains the most enigmatic of reproductive disorders. The extant written documents of Traditional Persian Medicine (TPM) - with holistic approaches towards human health - contain remedies used for centuries. Before further experimental research on any of these treatments, it is appropriate to study current related scientific evidence on their possible pharmacological actions. This work aims to study PCOS and its treatments in TPM. To collect data from medieval medicinal texts, six of the most famous manuscripts of Persian medicine were studied. Medicinal treatments for a problem similar to PCOS were searched for in these books. The plants were listed and their authentications were confirmed in accordance with botanical books. PubMed and ScienceDirect databases were searched for related mechanisms of action or pharmacological activities of the medicinal plants reported. From numerous articles, the current work tried to cite the latest publications with regard to each reported plant and PCOS-related mechanisms of action. We studied herbal treatments recommended by ancient Persians to treat a condition called Habs-e-tams, which had the same symptoms of PCOS. It could be concluded that ancient physicians not only wanted to treat the irregular menstrual cycle-which is the most obvious symptom of PCOS-but also their treatment options were aimed at ameliorating the related underlying metabolic dysfunctions. The recommended herbs, which have the most scientific proof for their related actions, can be studied further in experimental analyses.

Mentha longifolia protects against acetic-acid induced colitis in rats

ETHNOPHARMACOLOGICAL RELEVANCE

Mentha longifolia L (Wild Mint or Habak) (ML) is used in traditional medicine in treatment of many gastrointestinal disorders.

AIM OF THE STUDY

This study aimed to evaluate potential protecting effect of ML and its major constituent, eucalyptol, against acetic acid-induced colitis in rats, a model of human inflammatory bowel disease (IBD).

MATERIALS AND METHODS

Rats were divided into ten groups (n=8) given orally for three days (mg/kg/day) the following: normal control, acetic acid-induced colitis (un-treated, positive control), vehicle (DMSO), sulfasalazine (500), ML extract (100, 500, 1000), and eucalyptol (100, 200, 400). After 24h-fasting, two ML of acetic acid (3%) was administered intrarectally. On the fifth day, serum and colonic biochemical markers, and histopathological changes were evaluated.

RESULTS

Colitis significantly increased colonic myeloperoxidase activity and malonaldehyde level, and serum tumor necrosis factor-α, interleukin-6, and malonaldehyde levels while significantly decreased colonic and serum glutathione levels. All treatments (except ML 100, ML 1000, and eucalyptol 100) significantly reversed these changes where eucalyptol (400) showed the highest activity in a dose-dependent manner. The colitis-induced histopathological changes were mild in sulfasalazine and eucalyptol 400 groups, moderate in ML 500 and eucalyptol 200 groups, and severe in ML 100, ML 1000, and eucalyptol 100 groups nearly similar to colitis-untreated rats.

CONCLUSION

ML (in moderate doses) and eucalyptol (dose-dependently) exerted protective effects against acetic acid-induced colitis in rats possibly through antioxidant and antiinflammatory properties suggesting a potential benefit in treatments of IBD. To our knowledge this is the first report addressing this point.

Heart palpitation relief with Melissa officinalis leaf extract: double blind, randomized, placebo controlled trial of efficacy and safety

ETHNOPHARMACOLOGICAL RELEVANCE

In Traditional Iranian Medicine (TIM), Melissa officinalis L. is commonly regarded as an effective therapy for heart palpitations.

OBJECTIVE

Heart palpitation is a common complaint that is often benign and associated with a marked distress that makes the condition difficult to treat. Herbal medicines provide an alternative to conventional drugs for treating various kinds of diseases. This study was done as a double blind randomized placebo-controlled clinical trial to evaluate the efficacy and safety of the dried extract of M. officinalis on adults suffering from benign palpitations.

MATERIALS AND METHODS

Eligible volunteers were randomly assigned as outpatients to a 14 day treatment with 500 mg twice a day of lyophilized aqueous extract of M. officinalis leaves (or placebo). Participants in the tests, physicians and researchers were blind to group assignments. Both primary and secondary outcomes were patient-reported. Primary outcomes were obtained from two measures: mean frequency of palpitation episodes per week, derived from patients׳ diaries, and mean intensity of palpitation estimated through Visual Analogue Scale (VAS) in a self-report questionnaire. Psychiatric symptoms (somatization, anxiety and insomnia, social dysfunction and severe depression) were evaluated as secondary outcomes by General Health Questionnaire-28 (GHQ-28), before and after intervention.

RESULTS

Fifty-five volunteers out of 71 recruited study subjects completed the trial. Results showed that 14-day of treatment with lyophilized aqueous extract of M. officinalis leaves reduced frequency of palpitation episodes and significantly reduced the number of anxious patients in comparison to the placebo (P=0.0001, P=0.004 resp.). Also, M. officinalis extract showed no indication of any serious side effects.

CONCLUSION

Lyophilized aqueous extract of M. officinalis leaves may be a proper and safe herbal drug for the treatment of benign palpitations.

Effect of myrtle fruit syrup on abnormal uterine bleeding: a randomized double-blind, placebo-controlled pilot study

Background

Myrtle (Myrtus communis L.) has been used in the Iranian Traditional Medicine as a treatment for abnormal uterine bleeding-menometrorrhagia. The main aim of this study is to evaluate the effect of myrtle fruit syrup on abnormal uterine bleeding-menometrorrhagia.

Methods

A randomized, double-blind, placebo-controlled pilot study was conducted on 30 women suffering from abnormal uterine bleeding-menometrorrhagia. Treatment comprised of giving 15 ml oral myrtle syrup daily (5 ml three times a day) for 7 days starting from the onset of bleeding. The myrtle syrup along with placebo was repeated for 3 consecutive menstrual periods. Menstrual duration and number of used pads were recorded by the Pictorial Blood loss Assessment Chart at the end of each menstrual period. The quality of life was also evaluated using the menorrhagia questionnaire.

Results

The mean number of bleeding days significantly declined from 10.6 ± 2.7 days to 8.2 ± 1.9 days after 3 months treatment with the syrup (p = 0.01) and consequently the participants in the intervention group used fewer pads after 3 months (16.4 ± 10.7) compared with the number of pads used at the beginning of the treatment (22.7 ± 12.0, p = 0.01). Bleeding days and number of pads used by the participants in the placebo group did not change significantly. Also significant changes of quality of life scores were observed in the intervention group after 3 months compared to the baseline.

Conclusion

Myrtle syrup is introduced as a potential remedy for abnormal uterine bleeding-menometrorrhagia.

Effect of Linum usitatissimum L. (linseed) oil on mild and moderate carpal tunnel syndrome: a randomized, double-blind, placebo-controlled clinical trial

BACKGROUND

Carpal tunnel syndrome is known as the most common entrapment neuropathy. Conservative treatments cannot reduce the symptomatic severity satisfactorily; therefore, effectiveness of Linum usitatissimum L. (linseed) oil on carpal tunnel syndrome, as a complementary treatment, was evaluated in the current study. Linseed oil is a well-known preparation in Iranian traditional medicine and its analgesic, anti-inflammatory and anti-oxidative effects have been shown in previous studies.

METHODS

A randomized, double-blind, placebo-controlled clinical trial was conducted. One hundred patients (155 hands) with idiopathic mild to moderate carpal tunnel syndrome aged between 18 and 65 years old were randomized in two parallel groups. These two groups were treated during 4 weeks with topical placebo and linseed oil. In addition, a night wrist splint was prescribed for both groups. Symptomatic severity and functional status were measured using Boston Carpal Tunnel Questionnaire. In addition, median sensory nerve conduction velocity, motor distal latency, sensory distal latency and compound latency as electrodiagnostic parameters were measured at baseline and after the intervention period.

RESULTS

After the intervention, significant improvement was observed regarding Boston Carpal Tunnel Questionnaire symptomatic severity and functional status mean differences (p <0.001) in the linseed oil group compared with those in the placebo group. Also, regarding the mean differences of both groups, significant improvement of nerve conduction velocity of the median nerve was seen in the linseed oil group by a value of 2.38 m/sec (p < 0.05). However, motor distal latency and sensory distal latency of the median nerve showed no between-group significant changes (p = 0.14 for both items). Finally, compound latency was improved slightly in the case group, comparing mean differences between the groups (p <0.05). No significant adverse events were reported from using linseed oil.

CONCLUSIONS

It seems that linseed oil could be effective in the management of mild and moderate carpal tunnel syndrome, especially in improving the severity of symptoms and functional status. In addition, its effect on electerodiagnostic parameters, especially on the nerve conduction velocity, can be considered as a valuable point.

A Review of Pioneer Physicians' Work on Maternal Health in Pregnancy in Ancient Iran; Narrative Systematic Review

Background Maternal lifestyle and behaviors during pregnancy have been associated with future health outcomes for mothers and babies. Iranian Traditional medicine, which is a holistically-oriented medical discipline, has special attitudes towards pregnancy. The purpose of the study is the investigation of maternal health in medical books of ancient Iran. This study is a systematic review scrutinizing issues concerning lifestyle during pregnancy based on "Avicenna's Canon medicine" and "Rhazes Al-Havi" and for complete discussion, other reliable sources in traditional medicine which was conducted following the categorization and analysis of the gleaned data.
