The effect of two-month treatment with Zataria multiflora on inflammatory cytokines, pulmonary function testes and respiratory symptoms in patients with chronic obstructive pulmonary disease (COPD)

ETHNOPHARMACOLOGICAL RELEVANCE

Zataria multiflora Boiss. (Z. multiflora) is a valuable medicinal plant that has been used in Iranian traditional and folk medicine as an antiseptic, carminative, diaphoretic, diuretic, anti-spasmodic and analgesic herbal medicine. This plant has been also used to relieve cough in common cold and respiratory tract disorders. The previous studies reported the pharmacological effects of Z. multiflora such as anti-inflammatory and anti-oxidant properties in respiratory disorders in animal models and clinical studies.

AIM OF THE STUDY

The effects of Z. multiflora extract on inflammatory cytokines, pulmonary function tests (PFT), and respiratory symptoms in chronic obstructive pulmonary diseases (COPD) patients were investigated.

MATERIALS AND METHODS

COPD patients (41 cases) were divided to three groups including placebo group (P) and groups received 3 and 6 mg/kg/day Z. multiflora extract (Z3 and Z6) for two months. Inflammatory cytokines, PFT values, and respiratory symptoms were assessed before treatment (stage 0), one (stage I) and two (stage II) months after treatment.

RESULTS

Serum levels of TNF-α and IL-8 were significantly decreased after two months treatment compared to baseline values in Z3 and Z6 groups. The PFT values including forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were significantly increased during two months treatment with Z3 and Z6. The peak expiratory flow (PEF) was also significantly increased after one-month treatment with Z6. The respiratory symptoms including cough, chest tightness, modified medical research council (mMRC) dyspnea scale were significantly improved after one and two treatments with both doses of Z. multiflora compared to baseline values.

CONCLUSION

The results suggest the potential therapeutic effect of Z. multiflora in COPD patients through reduction of inflammatory cytokines, increasing PFT values and improvement of respiratory symptoms.

Malva parviflora Leaves and Fruits Mucilage as Natural Sources of Anti-Inflammatory, Antitussive and Gastro-Protective Agents: A Comparative Study Using Rat Models and Gas Chromatography

Malva parviflora L., Little mallow, has been traditionally used as an alternative food source. It acts as a medicinal herb containing a potential source of mucilage thus herein; we aimed to assess the toxicity, anti-inflammatory, antitussive and gastro-protective actions of M. parviflora mucilage extracted from its leaves (MLM) and fruit (MFM). Toxicity studies were investigated by in vitro hemolytic assay whereas acute anti-inflammatory and antitussive activities were assessed by carrageenan-induced paw edema and sulphur dioxide induced cough model in rats, respectively. Gastro-protective effects were studied using ethanol induced acute and chronic gastric ulcer rat models. Their metabolic profiles were determined using gas chromatography. The results revealed that MLM and MFM were non-toxic towards human erythrocytes and their lethal doses were found to be greater than 5 g/kg. Pretreatment with MLM (500 mg/kg) and MFM (500 mg/kg) significantly reduced the carrageenan-induced paw thickness (p < 0.001). Maximum edema inhibition (%) was observed at 4 h in diclofenac sodium (39.31%) followed by MLM (27.35%) and MFM (15.68%). Animals pretreated with MLM (500 mg/kg) significantly lower the cough frequency in SO2 gas induced cough models in contrast to control. Moreover, MLM at doses of 250 and 500 mg/kg reduced the ethanol induced gastric mucosal injuries in acute gastric ulcer models presenting ulcer inhibition of 23.04 and 38.74%, respectively. The chronic gastric ulcer model MFM (500 mg/kg) demonstrated a remarkable gastro-protective effect showing 63.52% ulcer inhibition and results were closely related to standard drug sucralfate. In both models, MLM and MFM decreased gastric juice volume and total acidity in addition to an increased gastric juice pH and gastric mucous content justifying an anti-secretary role of this mucilage that was further confirmed by histopathological examination. Meanwhile, GC analyses of the mucilage revealed their richness with natural as well as acidic monosaccharides. It is concluded that MLM and MFM can be used therapeutically for the management of inflammation, cough and gastric ulcer.

Zataria multiflora extract influenced asthmatic patients by improving respiratory symptoms, pulmonary function tests and lung inflammation

ETHNOPHARMACOLOGICAL RELEVANCE

Anti-inflammatory and anti-oxidant effects of Zataria multiflora Boiss (Z. multiflora) were reported in previous studies which is using in traditional and modern medicine. This plant is traditional used as an anti-tussive agent and for the management of respiratory disorders.

AIM OF THE STUDY

The preventive effect of the extract of leaves and stems of Z. multiflora on respiratory symptoms, pulmonary function tests, hematological indices, high sensitivity C-reactive protein (hs-CRP), level of interleukin-10 (IL-10) in the serum and supernatant of cultured peripheral blood mononuclear cells (PBMC) and gene expression of IL-10 in these cells in asthmatic patients was studied.

MATERIALS AND METHODS

36 asthmatic patients in three groups (randomly divided) of placebo group (P), two groups treated with 5 and 10 mg/kg/day doses of Z. multiflora (Z5 and Z10) for two months completed the study. Drugs were administered double-blindly and different variables were assessed before and after (one and two months) starting treatment including respiratory symptoms, pulmonary function tests (PFT), hematological indices, hs-CRP, serum and supernatant levels as well as gene expression of IL-10.

RESULTS

Two months treatment with Z5 and Z10 led to significant reduction of respiratory symptoms (p < 0.05 to p < 0.001). Pulmonary function test values in treated groups were also significantly increased two months after starting treatment (p < 0.05 to p < 0.001). Total WBC, monocytes and eosinophils were also decreased in treated groups with the extract at the end of study period (p < 0.05 to p < 0.01). Hemoglobin and hematocrit in Z10 treated group (p < 0.05 and p < 0.01, respectively) and mean corpuscular volume (MCV) in both treated groups (p < 0.05 to p < 0.01) were significantly reduced. In addition, the level of hs-CRP in both treated groups was significantly reduced after two months (p < 0.05 to p < 0.01). IL-10 concentration in Z10 treated group in supernatant of PBMC was also significantly enhanced (p < 0.01). All comparisons were made compared to the baseline (beginning of the treatment) values.

CONCLUSION

Z. multiflora improved respiratory symptoms and increased pulmonary function tests in asthmatic patients. In addition, the plant was effective in decrement of inflammatory cells and hs-CRP as well as enhanced IL-10. Therefore, the plant showed possible preventive therapeutic effect on asthma.

The effect of Zataria multiflora on respiratory allergic and immunologic disorders, experimental and clinical evidence: A comprehensive review

Zataria multiflora (Z. multiflora) is used in traditional and modern medicine for therapeutic objectives especially in respiratory disorders. Therefore, updated experimental and clinical studies on the effects of Z. multiflora on respiratory, allergic, and immunologic disorders are reviewed. Various electronic search engines including PubMed, Science Direct, Scopus, and Google Scholar were searched using appropriate keywords until the end of November 2021. Books, thesis-hard copies of some articles were also included. The effects of Z. multiflora on respiratory disorders including asthma, chronic obstructive pulmonary disease (COPD), lung infection, and lung cancer were shown. Extracts of Z. multiflora showed the relaxant effect with various mechanisms. The preventive effects of Z. multiflora were also demonstrated by mechanisms such as antioxidant, immunomodulatory, and antiinflammatory properties in the experimental animal models of different respiratory diseases. Carvacrol and thymol are probably responsible for the therapeutic effect of plant among 56 constituents of Z. multiflora. In addition, bronchodilatory and preventive effects of the plant and its constituents on asthma, COPD, lung disorders due to noxious agents and allergic and immunologic disorders were shown in the clinical studies. Therefore Z. multiflora and its constituents may be considered as a preventive and/or relieving therapy in various respiratory diseases.

Non-pharmacological remedies for post-viral acute cough

The post-viral acute cough (PAC) is a widespread symptom, mainly in childhood and adolescence, and is usually associated with an acute upper respiratory infection, namely the common cold. The use of cough relievers is, therefore, impressive, as documented by the market data. There are many medical devices and dietary supplements for treating PAC, which contain non-pharmacological components. Ancient people used traditional herbs to treat PAC. Thus, a well-established tradition considers natural remedies as an effective and safe way to relieve PAC. The herbal agents include polyphenols, flavonoids, saponins, glucosides, and alkaloids. Also, the European Medicine Agency has recognized the value of plant extracts and other natural substances to treat PAC. Nevertheless, a few studies investigated the role of non-pharmacologic remedies for PAC. There is some evidence for honey, glycerol, Althea officinalis, Drosera rotundifolia, Grindelia, Hedera helix, Pelargonium sidoides, Sambucus nigra, Thymus vulgaris, hyaluronic acid, and saline solutions. However, further rigorous studies should confirm natural products' efficacy and safety to relieve PAC.

Carvacrol improves pulmonary function tests, oxidant/antioxidant parameters and cytokine levels in asthmatic patients: A randomized, double-blind, clinical trial

BACKGROUND

Carvacrol effects on inflammatory mediators, lung pathology and tracheal responsiveness were indicated in animal models of pulmonary diseases.

PURPOSE

To evaluate carvacrol effects on respiratory symptoms, pulmonary function tests (PFT), oxidative stress markers and cytokine levels in asthmatic patients.

STUDY DESIGN

This study was a randomized, placebo-controlled double-blind, clinical trial.

METHODS

Thirty-three moderate asthmatic patients were divided to the two groups of: placebo group (n = 16) and carvacrol group (1.2 mg/kg/day, n = 17). Prepared capsules were taken for two months along, 3 times/day along with routine medications. Respiratory symptoms, PFT, and oxidative stress markers were evaluated before the treatment (step 0), and one (step I) and two months (step II) after the beginning of the treatment. However, cytokine levels in serum and supernatant of peripheral blood mononuclear cells (PBMC), and their gene expression were evaluated in step 0 and II.

RESULTS

In carvacrol-treated group, respiratory symptoms significantly decreased after one- and two-month treatment with carvacrol compared to pre-treatment values (p < 0.05 to p < 0.001). Compared to step 0, PFT values were significantly increased in step I and II, in treated group with carvacrol (p < 0.05 to p < 0.001). Most oxidative stress markers were improved following carvacrol treatment (p < 0.05 to p < 0.001). Treatment with carvacrol for two-month also significantly improved cytokine levels in serum and supernatant of PBMC, compared to step 0 (p < 0.05 to p < 0.001). However, no significant changes were observed in the above-noted parameters in the placebo group.

CONCLUSION

Due to anti-inflammatory and antioxidant effect, carvacrol could be suggested as a therapeutic agent for asthma.

The effects of Hedera helix on viral respiratory infections in humans: A rapid review

Brief overview

Based on the evidence identified in this rapid review, Hedera helix preparations and herbal complex preparations including H. helix may be a therapeutic option for treating early symptoms of respiratory tract infections. The best effectiveness for H. helix preparations has been proven for coughing, as an expectorant and to reduce the frequency and intensity of cough. Only weak evidence was found for all other researched symptoms. Both adults and children tolerate H. helix well. Currently, there is insufficient evidence to recommend the use of this supplement in the treatment or prevention of COVID-19. However, the current evidence justifies further research to better understand its applicability in coronavirus infections.

Verdic

tCurrent evidence suggests H. helix may improve the frequency and intensity of cough associated with viral respiratory infection. The overall applicability of additional findings is limited by the poorly defined outcome measures employed. However, studies focused explicitly on expectoration did report an increased conversion from dry to productive cough, and an improvement in expectoration amount, consistency and colour. These effects may be explained by a related finding of reduced oropharyngeal congestion and improved inflammatory markers (erythrocyte sedimentation rate and c-reactive protein). A decrease in frequency of night cough and respiratory pain was also reported, as was improved sleep quality and reduced cough-related sleep disturbance.

Some studies also measured general respiratory tract infection symptoms and identified clinical improvement or resolution of fever, fatigue, sore throat, sneezing, wheezing, nasal congestion, post-nasal drip and body-ache. A reduced need for antibiotic prescriptions was also identified. While not consistently reported, the majority of studies also found H. helix reduced the overall severity of viral bronchitis and related conditions. Tolerability was rated as between ‘good’ and ‘high’. Adverse events were rare or non-existent in almost all studies, and those that were reported were defined as non-serious and not drug-related.

Zataria multiflora affects clinical symptoms, oxidative stress and cytokines in asthmatic patient: A randomized, double blind, placebo-controlled, phase II clinical trial

BACKGROUND

Z. multiflora effect on clinical symptoms, pulmonary function tests (PFT), oxidative stress and cytokine levels in asthmatic patients were evaluated.

METHODS

Medications were administered three times a day for two months and several parameters were evaluated before treatment (step 0), one (step 1) and two months (step 2) after treatment.

RESULTS

Clinical symptoms and PFTs were significantly improved in Z5 and Z10 groups in steps 1 and 2 compared to step 0 (p < 0.05 to p < 0.001). Improvement of oxidative stress, cytokines levels and their gene expression after treatment with both doses of extract were observed in step 2 compared to step 0 (p < 0.05 to p < 0.001).

CONCLUSION

These results indicated therapeutic value of Z. multiflora for the management of asthma.

Therapeutic options to treat mustard gas poisoning - Review

Among the blistering (vesicant) chemical warfare agents (CWA), sulfur mustard is the most important since it is known as the "King of chemical warfare agents". The use of sulfur mustard has caused serious damages in several organs, especially the eyes, skin, respiratory, central and peripheral nervous systems after short and long term exposure, incapacitating and even killing people and troops. In this review, chemical properties, mechanism of actions and their effects on each organ, clinical manifestations, diagnostic evaluation of the actions triage, and treatment of injuries have been described.

Integration of botanicals in contemporary medicine: road blocks, checkpoints and go-ahead signals

The use of botanicals for maintaining good health and preventing diseases is undisputed. The claimed health benefits of natural health products and herbal medicines are based on traditional claims, positive results obtained in preclinical studies and early phase clinical trials that are not backed by safety and efficacy evidences approved by regulatory agencies. Although, the popularity of botanicals is growing, health care practitioners of modern medicine seldom recommend their use because of ill equipped database of their safety and potency. This review discusses problems that preclude botanicals from integrating into the mainstream contemporary therapeutics and cues that provide impetus for their realisation.

Medicinal plants--prophylactic and therapeutic options for gastrointestinal and respiratory diseases in calves and piglets? A systematic review

BACKGROUND

Gastrointestinal and respiratory diseases in calves and piglets lead to significant economic losses in livestock husbandry. A high morbidity has been reported for diarrhea (calves ≤ 35%; piglets ≤ 50%) and for respiratory diseases (calves ≤ 80%; piglets ≤ 40%). Despite a highly diverse etiology and pathophysiology of these diseases, treatment with antimicrobials is often the first-line therapy. Multi-antimicrobial resistance in pathogens results in international accordance to strengthen the research in novel treatment options. Medicinal plants bear a potential as alternative or additional treatment. Based on the versatile effects of their plant specific multi-component-compositions, medicinal plants can potentially act as 'multi-target drugs'. Regarding the plurality of medicinal plants, the aim of this systematic review was to identify potential medicinal plant species for prevention and treatment of gastrointestinal and respiratory diseases and for modulation of the immune system and inflammation in calves and piglets.

RESULTS

Based on nine initial sources including standard textbooks and European ethnoveterinary studies, a total of 223 medicinal plant species related to the treatment of gastrointestinal and respiratory diseases was identified. A defined search strategy was established using the PRISMA statement to evaluate 30 medicinal plant species starting from 20'000 peer-reviewed articles published in the last 20 years (1994-2014). This strategy led to 418 references (257 in vitro, 84 in vivo and 77 clinical trials, thereof 48 clinical trials in veterinary medicine) to evaluate effects of medicinal plants and their efficacy in detail. The findings indicate that the most promising candidates for gastrointestinal diseases are Allium sativum L., Mentha x piperita L. and Salvia officinalis L.; for diseases of the respiratory tract Echinacea purpurea (L.) MOENCH, Thymus vulgaris L. and Althea officinalis L. were found most promising, and Echinacea purpurea (L.) MOENCH, Camellia sinensis (L.) KUNTZE, Glycyrrhiza glabra L. and Origanum vulgare L. were identified as best candidates for modulation of the immune system and inflammation.

CONCLUSIONS

Several medicinal plants bear a potential for novel treatment strategies for young livestock. There is a need for further research focused on gastrointestinal and respiratory diseases in calves and piglets, and the findings of this review provide a basis on plant selection for future studies.

The Effect of Viola odorata Flower Syrup on the Cough of Children With Asthma: A Double-Blind, Randomized Controlled Trial

This study aimed to investigate the effect of violet syrup on cough alleviation in children with intermittent asthma. In a parallel, double-blind, randomized controlled trial, 182 children aged 2 to 12 years with intermittent asthma were randomly assigned 1:1 to receive violet syrup or placebo along with the common standard treatments in both groups (short-acting β-agonist). Both groups were evaluated in terms of the duration until cough suppression was achieved. No significant difference was observed in basic characteristics. The duration lasting to yield more than 50% cough reduction and 100% cough suppression was significantly less in the violet syrup group compared to placebo (P = .001, P < .001, respectively). There was no significant difference in therapeutic effects between boys and girls. There was a significant inverse correlation between the age of children and rate of cough alleviation and suppression by violet syrup. This study showed that the adjuvant use of violet syrup with short-acting β-agonist can enhance the cough suppression in children with intermittent asthma.

Local people were recorded to use the aerial parts, branches, flowers, fruits, latex, leaves, matured fruits, peduncle, resin, rhizomes, root bark, roots, seeds and style of the plants. Besides, it was observed that they dried and stored plants in unfavorable seasons in order to use them later. The medicinal uses of Heracleum antasiaticum Manden., Pimpinella olivieroides Boiss. & Hausskn., Scandix iberica Bieb., Taraxacum hybernum Stev., Tripleurospermum transcaucasicum (Manden.) Pobed., Cerastium chlorifolium Fisch. & Mey., Andrachne telephioides L., Euphorbia denticulata Lam., Astragalus cephalotes Banks. & Sol. var. brevicalyx Eig., Geranium ibericum Cav., Cyclotrichium nivenum (Boiss.) Manden. & Scheng., Salvia syriaca L., Papaver arenarium Bieb., Dactylis glomerata L., Polygonum arenarium Waldst. & Kit. that we found were used in our study area and recorded for the first time. No information could be obtained regarding the names of eight wild plants that are being used in Malatya. In Turkey, local plant names display differences especially due to ethnographic reasons. The plants used in Malatya are known by the same or different local names in various parts of Anatolia. Our research area also includes people with Kurdish and Zaza ethnic origins. The respondents of the questionnaire are Turkish citizens.

CONCLUSION

These plants are used in the treatment of many diseases. Comparison of the data obtained in this study from derived the plants growing in Malatya with the experimental data obtained in previous laboratory studies proved ethnobotanical usages to a great extent. Literature review indicated that curative plants that grow in Malatya are used in different parts of the world for the treatment of the same or similar diseases. These plants, used for the treatment of many varying diseases, are abundantly found in this region. Drying enabled local people to use medicinal plants in every seasons of the year. The plant flora of Malatya is threatened by such factors as grazing, expansion of new agricultural lands, and unsustainable picking of plants to generate income. Steps should be taken immediately to ensure the inclusion of relevant flora within conservation designations.

Ethnopharmacological survey of medicinal plants in Maden (Elazig-Turkey)

AIM OF THE STUDY

This study aimed to identify wild plants collected for medical purposes by the local people of Maden County, located in the Eastern Anatolia Region of Turkey, and to establish the uses and local names of these plants.

MATERIALS AND METHODS

Field study was carried out over a period of approximately 2 years (2008-2010). During this period, 131 vascular plant specimens were collected. Demographic characteristics of participants, local plant names, utilized parts and preparation methods of the plants were investigated and recorded. In the scope of the study, the plant species were collected; herbarium materials were prepared; and the specimens were entitled. The Zazas are of the major ethnic group in the region. In addition, the relative importance value of the species was determined and informant consensus factor (FIC) was calculated for the medicinal plants included in the study.

RESULTS

A total of 88 medical plants belonging to 41 families were identified in the region. 4 plants out of 88 were recorded to be used for curative purposes for the first time. It was determined that the local names of four different kinds of plants used in Maden were same as the different kinds of plants used in different regions. The most encountered medicinal plant families were Urticaceae (>21%), Rosaceae and Lamiaceae (>17% of use-reports), Asteraceae (>13%), Fabaceae (>8%), Brassicaceae (>7%), Poaceae (>4%); the most common preparations were decoction and infusion. Mentha spicata L. subsp. spicata, Rosa canina L. and Urtica dioica L. was the plants most used by the local people. Anthemis wiedemanniana Fisch. and Mey., Bunium paucifolium DC. var. brevipes (Freyn & Sint.) Hedge & Lam., Tchihatchewia isatidea Boiss., Thymus haussknechtii Velen. were found to be the endemic plants used for medical purposes in Maden, Turkey.

Systematic review of clinical trials assessing the effectiveness of ivy leaf (hedera helix) for acute upper respiratory tract infections

Introduction. Among nonantibiotic cough remedies, herbal preparations containing extracts from leaves of ivy (Hedera helix) enjoy great popularity. Objective. A systematic review to assess the effectiveness and tolerability of ivy for acute upper respiratory tract infections (URTIs). Methods. We searched for randomized controlled trials (RCTs), nonrandomized controlled clinical trials and observational studies evaluating the efficacy of ivy preparations for acute URTIs. Study quality was assessed by the Jadad score or the EPHPP tool. Results. 10 eligible studies were identified reporting on 17463 subjects. Studies were heterogeneous in design and conduct; 2 were RCTs. Three studies evaluated a combination of ivy and thyme, 7 studies investigated monopreparations of ivy. Only one RCT (n = 360) investigating an ivy/thyme combination used a placebo control and showed statistically significant superiority in reducing the frequency and duration of cough. All other studies lack a placebo control and show serious methodological flaws. They all conclude that ivy extracts are effective for reducing symptoms of URTI. Conclusion. Although all studies report that ivy extracts are effective to reduce symptoms of URTI, there is no convincing evidence due to serious methodological flaws and lack of placebo controls. The combination of ivy and thyme might be more effective but needs confirmation.

Phytoceuticals: the new 'physic garden' for asthma and chronic obstructive pulmonary disease

Phytoceuticals (non-nutritional but beneficial plant chemicals) merit investigation as pharmacotherapy for asthma and chronic obstructive pulmonary disease (COPD). Although asthma is mostly treated adequately, COPD is not. Thus, there is a need for new drugs with improved therapeutic benefit, especially in COPD. Recent interest in herbal remedies has redirected attention towards plants as sources of improved treatments for lung disease. Phytoceuticals from a variety of plants and plant products, including butterbur, English ivy, apples, chocolate, green tea and red wine, demonstrate broad-spectrum pharmacotherapeutic activities that could be exploited in the clinic. Well-designed clinical trials are required to determine whether these beneficial activities are reproduced in patients, with the prospect that phytoceuticals are the new physic garden for asthma and COPD.

Traditional uses of medicinal plants in Valvestino (Italy)

This paper reports the results of a survey concerning folk uses of medicinal plants in Valvestino (Brescia, Italy). The features of this area, recognized by European Union as "Site of Community interest", allowed the preservation of the ethnobotanical traditions. We have documented the use of 58 species belonging to 30 families by interviewing 54 villagers of a mean age of 72 years. The dominant families are Asteraceae (10 species), Pinaceae and Rosaceae (5 species, respectively); the most common preparations are infusion and decoction. Three plants have been mentioned for treatment of animals, some species are employed in cookery. The study, carried out for the first time in this valley, gathered information about traditional remedies, before they are completely lost. All the interesting species have been transplanted to the G. E. Ghirardi Botanical Garden for the ex situ conservation.
