Traditional Herbal Remedies Used for Managing Anxiety and Insomnia in Italy: An Ethnopharmacological Overview

A Comparison of the Effect of Two Doses of Oral Melatonin as Premedication on Orientation Score, Induction Compliance, and Emergency Agitation of Children Undergoing Elective Surgeries: A Double-Blinded Randomized Trial

Background: Following sedation or general anesthesia, emergent agitation (EA) presents as a sequence of abrupt, complicated psychomotor problems marked by perceptual abnormalities, delusions, and disorientation. Studies have proved that melatonin significantly decreases the incidence of postoperative agitation in children after anesthesia. The primary objective of this study was to compare the effectiveness of two doses of oral melatonin as a premedication for orientation score, induction compliance, and emergency agitation of children undergoing surgeries. Methods: In this double-blinded randomized controlled trial, 126 children, aged 4-14, of either sex, with an ASA I or II, scheduled for elective surgery were randomly assigned to get either melatonin 0.4 mg/kg (Group M4) or melatonin 0.2 mg/kg (Group M2), with 63 kids in each group. All children have had the same anesthetic strategy. As a primary outcome, orientation score, induction compliance to intravenous induction anesthesia, and decreased emergency agitation were assessed. Results: Both groups were comparable in terms of demographic characteristics and baseline data. Orientation scores were similar between the groups. Preoperatively, all patients were oriented in both time and place. The two groups had no statistically significant difference according to induction compliance distribution (p=0.065). There was a statistically significant difference in agitation behavior after 5, 10, and 15 min postoperatively in M 4, 2, and total participants (p < 0.001). Conclusion: In pediatric surgical patients, the melatonin dosage does not affect children's compliance with induction but impacts their postoperative behavior by reducing the likelihood of agitation. Administering oral melatonin before surgery could potentially aid in managing postoperative delirium in children.

Thyridiumlauri sp. nov. (Thyridiaceae, Thyridiales): a new pathogenic fungal species of bay laurel from Italy

Laurusnobilis is an important Mediterranean tree and shrub native to Italy that is also commercially grown as spice and ornamental plant. Field surveys conducted since 2021 in Sicily (Italy) revealed that bay laurel plants in urban and private gardens and nurseries were severely affected by symptoms of stem blight and internal necrosis, which were associated with ambrosia beetle entry holes in the bark and internal wood galleries. The occurring ambrosia beetle was identified as Xylosandruscompactus, an invasive wood-boring pest previously reported from Sicily. Investigation of fungi from symptomatic tissues primarily resulted in the isolation of Thyridium-like colonies. The main symbiont of X.compactus, Ambrosiellaxylebori, was also isolated from infested plants. Phylogenetic analyses of a combined matrix of ITS, LSU, act1, rpb2, tef1, and tub2 gene regions revealed that the isolated Thyridium-like colonies represent a new fungal species within the genus Thyridium. Based on both phylogeny and morphology, the new isolated fungus is described as Thyridiumlauri sp. nov. Moreover, two recently described species, Phialemoniopsishipposidericola and Phialemoniopsisxishuangbannaensis, are transferred to the genus Thyridium due to the confirmed synonymy of both genera, as supported by molecular phylogenies. Pathogenicity test conducted on potted plants demonstrated that T.lauri is pathogenic to bay laurel, causing internal necrosis and stem blight. The new species was consistently re-isolated from the symptomatic tissue beyond the inoculation point, thereby fulfilling Koch's postulates. This study represents the first report of a new pathogenic fungus, T.lauri, causing stem blight and internal necrosis of bay laurel plants and associated with infestation of the invasive ambrosia beetle X.compactus.

Plants with Potential Importance in Supporting the Treatment of Depression: Current Trends, and Research

Depression is one of the most common diseases in the world, and it is also the most common mental disorder. Depressive disorders are a real threat not only to individuals, but also to the general population. This disease is a leading cause of disability and inability to work. Due to the numerous side effects of conventional drugs, attention is increasingly being paid to other solutions, including herbal medicines. Many plant species are known for their traditional uses in the treatment of anxiety, insomnia, and depression. The clinically proven effects of adaptogenic raw materials on depression symptoms are probably related to the positive impact of some secondary metabolites (terpenoids, alkaloids, glucosinolates, phenols). Currently, it is emphasized that in many cases the antioxidant and anti-inflammatory properties of plant substances play a protective role at the neurocellular level. Among the medicinal plants analyzed in clinical trials for the treatment of depression, the following seem to be particularly interesting: saffron (Crocus L.), turmeric (Curcuma L.), ginkgo (Ginkgo L.), St. John's wort (Hypericum L.), and passionflower (Passiflora L.), which have broad and strong biological activity, well-documented history of action and use, and effectiveness in preventing and/or treating anxiety and depression. These plants are still in the sphere of biochemical and phytopharmaceutical research, the results of which are very promising.

Effects of chamomile (Matricaria chamomilla L.) on sleep: A systematic review and meta-analysis of clinical trials

OBJECTIVE

We aimed to investigate the effects of chamomile (Matricaria chamomilla L.) on sleep in this systematic review and meta-analysis of clinical trials.

METHODS

PubMed, Scopus, Web of Science, and Cochrane Library were searched until August 2023. All clinical trials that investigated the effects of chamomile on sleep, either in healthy or diseased adults, were eligible to enter the study. The quality of studies was assessed using the Cochrane tool. Random-effects meta-analysis was used to pool weighted mean differences (WMD) and 95 % CI for the outcomes assessed by at least three studies with relatively consistent participants.

RESULTS

The systematic review included ten studies (772 participants). Meta-analysis was conducted for the Pittsburgh Sleep Quality Index (PSQI) score and sleep length. A significant reduction in PSQI score (WMD: -1.88, 95 %CI: -3.46, -0.31, I2: 88.4 %, n = 5) was found. For other outcomes, meta-analysis was not conducted. Sleep onset latency or ease of getting to sleep were improved in three of the four studies. Daytime functioning measures, including fatigue severity index or postpartum fatigue scale, did not change in all three studies. Sleep efficiency did not change in two studies and deteriorated in one. The number of awakenings after sleep or staying asleep was improved in two of the three studies. No adverse events were reported in any of the studies although passive surveillance was used to assess adverse effects except in one study. Only one study surveyed the blinding success and tested the purity and/or potency of the used products.

CONCLUSION

Chamomile improved sleep, especially the number of awakenings after sleep or staying asleep; however, it did not lead to an improvement in the duration of sleep, percentage of sleep efficiency, and daytime functioning measures. Future studies are suggested to assess objective measures.

A feasibility study on indoor therapeutic horticulture to alleviate sleep and anxiety problems: The impact of plants and activity choice on its therapeutic effect

INTRODUCTION

Therapeutic horticulture (TH) is increasingly being applied for sub-health or patient mental health care. Whether plant and activity type will affect TH's effectiveness is unclear.

AIM

To evaluate the feasibility of an indoor TH for alleviating the anxiety symptoms and sleeping problems of people with poor sleep quality, and explore the potential affection of plant and activity type on health benefits.

METHOD

Thirty subjects (all with sleep problems and half with anxiety problems) were randomly assigned to three groups to do horticultural activities with ornamental plants, general aromatic plants, or aromatic plants with reported mental health functions, respectively. Six indoor TH activities were then held sequentially within two weeks. Psychological scales, subjective feedback questionnaires, and physiological indicators were used as evaluation indexes before and after horticulture activities.

RESULTS

The TH relieved subjects' sleep and anxiety problems and was particularly effective in alleviating anxiety among people with high anxiety levels. Using ornamental plants was more effective in relieving stress while functional aromatic plants performed better in sleep improvement and satisfaction to TH. Each horticultural activity could improve mood state but showed different effects on the vitality of the participants.

CONCLUSION

The above findings provided some basis for the potential benefits of selecting plants and activities based on psychological care needs in the development of TH plans. Future research that expands upon the current project is warranted. A larger sample size is beneficial for obtaining more powerful statistical results.

In Algeria, folk medicine remains a fundamental part of the local intangible knowledge. This study aims to conduct a comprehensive ethnomedicinal investigation and documentation of medicinal plants and the different plant formulations traditionally used in Algeria for the treatment of pain, psychiatric, and neurological disorders. It also intends to improve the current knowledge of Algerian folk medicine. Several scientific databases were used to accomplish this work. Based on this investigation, we identified 82 plant species belonging to 69 genera and spanning 38 distinct botanical families used as remedies to treat various psychological and neurological conditions. Their traditional uses and methods of preparation, along with their phytochemical composition, main bioactive constituents, and toxicity were noted. Therefore, this review provides a new resource of information on Algerian medicinal plants used in the treatment and management of neurological and psychological diseases, which can be useful not only for the documentation and conservation of traditional knowledge, but also for conducting future phytochemical and pharmacological studies.

Melissa officinalis L. nanoethosomal formulation: evaluation of antioxidant, enzyme inhibitory activities and in vitro toxicity

This work aimed to create an extract of Melissa officinalis L. with strong antiradical efficacy, characterize it, and enhance its long-term efficacy by developing an ethosomal formulation. DPPH and ABTS assays were used to test the antiradical activity of extracts with different ethanol ratios obtained from the aerial part. Phytochemical characterization of the extract with the highest activity, ethyl acetate fraction of 60% ethanol extract, was analyzed by HPLC. The active ethyl acetate fraction was loaded into ethosomes, and characterization and release studies of the formulation were performed. The released extract from the formulation exhibited substantial antiradical action as well as inhibition of collagenase (71.5%) and elastase (75.5%) enzymes. The toxicity of the active extract and the formulation was determined in the mouse fibroblast cell line. This study successfully developed a long-term antioxidant and enzyme inhibitor formulation containing M. officinalis, which stands out for its medicinal properties.

Plants and mental disorders: the case of Catalan linguistic area

Introduction: Mental disorders are among the leading causes of ill-health and disability worldwide. Despite the disease burden they cause, including significant direct and indirect impacts on individual's health and major social and economic consequences in all countries of the world, it is still one of the most neglected areas of public health. In such a context, the medicinal plants traditionally used to pale these pathologies are presented as a promising tool for future drug development for the management of mental health disorders. The aim of the present study is to analyze the information about plant species used to treat mental disorders in the Catalan linguistic area (CLA) and compare these traditional uses with pharmacological literature in order to evaluate the most quoted taxa and their uses and to provide a basis for further research. Methods: Data have been recovered from the "Etnobotànica dels Països Catalans" webpage (https://etnobotanica.iec.cat/) and the meta-analytic work carried out in the present study covers 27 prospections performed in different territories between 1990 and 2019. Descriptive statistics and quantitative ethnobotany were carried out and some ethnobotanical indices were calculated. Results and Discussion: The number of use reports analysed to treat mental disorders in CLA is 2,544 spread over 183 taxa belonging to 64 families, being the most cited the Malvaceae (29.36% of use reports), Lamiaceae (16.71%), Caprifoliaceae (7.94%), Rutaceae (7.47%) and Papaveraceae (6.01%). The most used taxa to treat or alleviate the mental disorders have been Tilia platyphyllos Scop. (24.53%), Valeriana officinalis L. (7.47%), Salvia officinalis L. (5.07%), Sambucus nigra L. (4.28%), and Ruta chalepensis L. (3.89%). The flowers or inflorescences (47.68%), followed by aerial part (23.49%), have been the most used plant parts, and tisane the most commonly used pharmaceutical form (78.03%). The most reported use is as sedative with 40.92%, followed by anticephalalgic (21. 19%) and tranquilizer (20.01%). The informant consensus factor (FIC) was 0.93, and 3.72% was the ethnobotanicity index (EI) value. The information is coincidental with at least one of the comprehensive pharmacological literature sources checked for 73.68% of ethnobotanical uses.

Ethnobotanical Documentation of the Uses of Wild and Cultivated Plants in the Ansanto Valley (Avellino Province, Southern Italy)

With approximately 2800 species, the Campania region has the richest vascular flora in southern Italy and the highest number of medicinal species reported in the Italian folk traditions. The study area is inserted in a wide rural landscape, still retaining a high degree of naturalness and is studied for the first time from an ethnobotanical point of view. By analyzing local traditional uses of wild plants in the Ansanto Valley area, the present study aims to contribute to the implementation of ethnobotanical knowledge concerning southern Italy. To gather ethnobotanical knowledge related to the Ansanto Valley, 69 semi-structured interviews were carried out through a snowball sampling approach, starting from locals with experience in traditional plant uses (key informants). A number of 117 plant species (96 genera and 46 families) were documented for traditional use from a total of 928 reports, of which 544 were about medicinal plants. New use reports on the utilization of plants for medicinal (5) and veterinary applications (8) in the Campania region and the whole Italian territory were outlined from our investigations. Sedum cepaea is reported as a medicinal plant for the first time in Italy and in the whole Mediterranean basin.

Effects of the aroma of lemone verbena (Aloysia citriodora Paláu) essential oil on anxiety and the hemodynamic profile before cesarean section: A randomized clinical trial

Background

Aromatherapy is a noninvasive method used for alleviating anxiety. Lemon verbena (Aloysia citriodora Paláu, LV) has been frequently used in traditional medicine as an anxiolytic agent due to its pharmacological ingredients.

Objective

This randomized controlled trial aimed to assess the effects of inhaling essential oil of LV on the level of anxiety and subsequent hemodynamic changes before cesarean section.

Methods

The recent study was a randomized single-blind trial. Participants (n = 84) were randomly divided into two groups: LV essential oil (group A) and placebo (group B). The intervention group underwent aromatherapy using three drops of LV essential oil at a distance of 10 cm for 30 min. The placebo group received aromatherapy in a similar fashion. The State-Trait Anxiety Inventory of Spielberger questionnaire was administered before and 5 min after aroma inhalation. Vital signs were recorded before and after aromatherapy. Likewise, pain severity was assessed using the Numeric Rating Scale and vital signs were recorded. Data were analyzed using t-test, χ 2, and the Kolmogrov-Smirnov test through SPSS21 software.

Results

Anxiety level was significantly attenuated in group A after aromatherapy. Heart rate, respiratory rate, and blood pressure decreased after inhalation; but no significant variation of pain scores was observed after inhalation in both groups.

Conclusion

We concluded that LV decreased preoperative anxiety in this recent study, therefore, aromatherapy with LV essential oil as a preemptive adjuvant to relieve anxiety before cesarean section is recommended by us; although more studies are required to endorse the results.

Volatile and Non-Volatile Content Determination and Biological Activity Evaluation of Fresh Humulus lupulus L. (cv. Chinook) Leaves and Inflorescences

In this work, the fresh leaves and inflorescences of Humulus lupulus L. cv. Chinook hops were investigated in order to describe their chemical composition and evaluate their biological activities. The analyses were carried out first on fresh untreated samples and then on pulverized ones using the SPME-GC-MS technique. In total, forty-two molecules belonging to different chemical classes were identified, and among these, twenty-three were terpene compounds. In order to carry out the activity assays, the powders were subjected to extraction with two different solvents (methanol and distilled water) by stirring and subsequent sonication at room temperature. To chemically characterize the extracts, the methanolic ones were analyzed by direct injection into the GC-MS apparatus, while the aqueous ones were analyzed by DI-SPME-GC-MS. In addition, with the aim to obtain information on the non-volatile content of the methanolic extracts, they were also subjected to derivatization, and the silylated derivatives were analyzed by GC-MS. The antioxidant activity was then evaluated by means of DPPH and ABTS assays after the determination of the total content of polyphenols and flavonoids. The greatest effects were observed on the methanolic extracts rather than on the aqueous ones. Furthermore, a preliminary study on the cytotoxic power of the methanolic extracts was also conducted on three different human cancer cell lines, such as non-small cell lung cancer (H1299), melanoma (A375) and breast cancer (MCF7). The obtained results showed that the two extracts induced a marginal effect on reducing breast tumor, melanoma and non-small cell lung cancer cell proliferation.

Iconic Arable Weeds: The Significance of Corn Poppy (Papaver rhoeas), Cornflower (Centaurea cyanus), and Field Larkspur (Delphinium consolida) in Hungarian Ethnobotanical and Cultural Heritage

There are an increasing number of initiatives that recognize arable weed species as an important component of agricultural biodiversity. Such initiatives often focus on declining species that were once abundant and are still well known, but the ethnographic relevance of such species receives little recognition. We carried out an extensive literature review on the medicinal, ornamental, and cultural applications of three selected species, Papaver rhoeas, Centaurea cyanus, and Delphinium consolida, in the relevant Hungarian literature published between 1578 and 2021. We found a great diversity of medicinal usages. While P. rhoeas stands out with its sedative influence, D. consolida was mainly employed to stop bleeding, and C. cyanus was most frequently used to cure eye inflammation. The buds of P. rhoeas were sporadically eaten and its petals were used as a food dye. All species fulfilled ornamental purposes, either as garden plants or gathered in the wild for bouquets. They were essential elements of harvest festivals and religious festivities, particularly in Corpus Christi processions. P. rhoeas was also a part of several children's games. These wildflowers were regularly depicted in traditional Hungarian folk art. In poetry, P. rhoeas was used as a symbol of burning love or impermanence; C. cyanus was frequently associated with tenderness and faithfulness; while D. consolida regularly emerged as a nostalgic remembrance of the disappearing rural lifestyle. These plants were also used as patriotic symbols in illustrations for faithfulness, loyalty, or homesickness. Our results highlight the deep and prevalent embeddedness of the three iconic weed species studied in the folk culture of the Carpathian Basin. The ethnobotanical and cultural embeddedness of arable weed species should also be considered when efforts and instruments for the conservation of arable weed communities are designed.

Edible Flowers Used in Some Countries of the Mediterranean Basin: An Ethnobotanical Overview

Edible flowers are becoming an essential component of people's nutrition in the Mediterranean basin. In the last decades, many researchers also have focused their attention on the nutritional composition of the edible flowers, as well as their antioxidant and antimicrobial properties, including studies on their safety issues. Despite the growing interest in the use of flowers in human nutrition, the ethnobotanical literature is lacking coverage of some important issues, particularly those which concern the use of flowers in the folk tradition. Only recently, a review regarding the contribution of 32 edible flowers to the Mediterranean diet was published. The aim of the present review is to document the plant lore regarding the wild and cultivated edible flowers consumed in the Mediterranean basin. Based on the 112 studies reviewed, we documented 251 taxa as being used in the Mediterranean basin as edible flowers. The plant species belong to 45 families and 141 genera. Asteraceae (54 taxa) is the most frequently cited family. Sambucus nigra L. is the most cited species. This study can be the basis for future research on the supposed bioactivity and toxicity of wild and cultivated flowers.

Metabolomics and chemometrics of seven aromatic plants: Carob, eucalyptus, laurel, mint, myrtle, rosemary and strawberry tree

INTRODUCTION

Arbutus unedo L. (strawberry tree), Ceratonia siliqua L. (carob), Eucalyptus camaldulensis Dehnh. (eucalyptus), Laurus nobilis L. (laurel), Mentha aquatica L. (water mint), Myrtus communis L. (common myrtle), and Rosmarinus officinalis L. (rosemary) are aromatic plants from the Mediterranean region whose parts and preparations are used for their nutritional properties and health benefits.

OBJECTIVES

To evaluate and compare the metabolites profile, total phenol content (TPC), and antioxidant activity of plant leaves for their future use. Gas chromatography-mass spectrometry (GC-MS) was used for metabolomics. Data comparison was performed by chemometrics.

METHODOLOGY

Polar and apolar extracts were analysed using untargeted GC-MS metabolomics followed by chemometrics (principal component analysis, heatmap correlation and dendrogram) to identify, quantify and compare the major organic compounds in the plants. Additionally, nuclear magnetic resonance (NMR) spectroscopy was used for the laurel polar extract to identify d-gluco-l-glycero-3-octulose whose presence was unclear from the GC-MS data. TPC and antioxidant assays were performed using classical methods (Folin-Ciocalteu, 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH)) and correlated to the phytochemical profiles.

RESULTS

Forty-three metabolites were identified including amino acids, organic acids, carbohydrates, phenols, polyols, fatty acids, and alkanes. Eight metabolites (d-fructose, d-glucose, d-mannose, gallic acid, quinic acid, myo-inositol, palmitic and stearic acids) were in common between all species. d-Gluco-l-glycero-3-octulose (37.29 ± 1.19%), d-pinitol (31.33 ± 5.12%), and arbutin (1.30 ± 0.44%,) were characteristic compounds of laurel, carob, and strawberry tree, respectively. Carob showed the highest values of TPC and antioxidant activity.

CONCLUSION

GC-MS metabolomics and chemometrics analyses are fast and useful methods to determine and compare the metabolomics profiling of aromatic plants of food and industrial interest.

Thymol Nanopolymer Synthesis and Its Effects on Morphine Withdrawal Syndrome in Comparison With Clonidine in Rats

The drug delivery system is valuable in the treatment of the disease. A nanopolymer as a thymol and Thymbra spicata release system was synthesized and its effects on morphine withdrawal syndrome in comparison with clonidine in rats were studied. The nanopolymer was characterized by different methods, namely, IR, HNMR, CNMR, GPC, DLS, and AFM. Thymol in T. spicata extract was assessed. The loading and release rate of thymol and T. spicata extract on the nanopolymer were evaluated by HPLC. The median lethal dose (LD50) of the T. spicata extract, thymol, extract nanopolymer, and thymol nanopolymer was studied. The frequency of jumping, rearing, and teeth chattering in naloxone-induced morphine withdrawal syndrome was studied. Synthesized nanopolymer was desirable as a carrier for the drug. The loaded amount of extract and thymol on nanopolymer was estimated 55 ± 3.2% and 48 ± 2.6% and the drug released was 71 and 68%, respectively. LD50 of the T. spicata extract, thymol, extract nanopolymer, and thymol nanopolymer was 975, 580, 1,250, and 650 mg/kg, respectively. This study showed that thymol nanopolymer was more effective than clonidine to reduce the frequency of morphine withdrawal symptoms. Our results suggest that T. spicata extract, thymol, extract nanopolymer, and thymol nanopolymer are mighty in reducing the narcotic withdrawal signs. The mechanism of action and therapeutic potential is maybe similar to clonidine.
