Yang J, Deng Z, Pei S, Zhang N. A feasibility study on indoor therapeutic horticulture to alleviate sleep and anxiety problems: The impact of plants and activity choice on its therapeutic effect. Complement Ther Med 2024; 81:103032. [PMID: 38452859 DOI: 10.1016/j.ctim.2024.103032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 01/19/2024] [Accepted: 03/04/2024] [Indexed: 03/09/2024] Open
Abstract
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.

Stojanović NM, Mladenović MZ, Randjelović PJ, Radulović NS. The potential of lemon balm (Melissa officinalis L.) essential oil as an anti-anxiety agent - is the citronellal the activity carrier? JOURNAL OF ETHNOPHARMACOLOGY 2023; 314:116661. [PMID: 37207879 DOI: 10.1016/j.jep.2023.116661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2023] [Revised: 05/11/2023] [Accepted: 05/17/2023] [Indexed: 05/21/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Among the fewest drugs discovered are those belonging to the class of anxiolytics. Although some drug targets for anxiety disorders are established, it is hard to modify and selectively choose the active principle for those targets. Thus, the ethnomedical approach to treating anxiety disorders remains one of the most prevalent ways for (self)managing the symptoms. Melissa officinalis L. (lemon balm) has been extensively used as an ethnomedicinal remedy for the treatment of different psyche-related symptoms, especially dose related to restlessness. AIM OF THE STUDY This work aimed to evaluate the anxiolytic activity, in several in vivo models, of the essential oil extracted from Melissa officinalis (MO) and its main constituent citronellal, a widespread plant utilized for managing anxiety. MATERIALS AND METHODS In the present study several animal models were used to assess MO anxiolytic potential in mice. The effect of the MO essential oil applied in doses ranging from 12.5 to 100 mg/kg was estimated in light/dark, hole board, and marble burying tests. In parallel doses of citronellal corresponding to the ones in the MO essential oil were applied to animals to determine if this is the activity carrier. RESULTS The results indicate that the MO essential oil exerts anxiolytic potential in all three experimental settings by significantly altering the traced parameters. The effects of citronellal are somewhat inconclusive and should not be interpreted only as anxiolytic but rather as a combination of anti-anxiety and motor-inhibiting effects. CONCLUSIONS In conclusion, we could say that the results of the present study provide a base for future mechanistic studies that would evaluate the activity of M. officinalis essential oil on various neurotransmitter systems involved in the generation, propagation, and maintenance of anxiety.

Abstract
Epileptic seizures are a consequence of uncontrolled neuronal discharge and demand urgent and prolonged treatment. Due to a lack of potent and low-risk drugs that could prevent seizures, efforts are underway to discover new drugs, and plant metabolites are often considered valuable candidates in this search. Lemon balm ( Melissa officinalis L., Lamiaceae) is a world-renowned medicinal plant affecting central nervous system function. In this study, we aimed to examine whether the results from in silico modeling of the interactions of major lemon balm essential oil constituents with GABAA and glycine receptors correspond to in vivo results of the convulsions in mice induced by the application of either pentylenetetrazol (GABAA antagonistic) or strychnine (glycine receptor antagonist). While molecular docking experiments of essential oil constituents to the two receptors demonstrated the possibility of ligand–receptor interactions, no binding poses were scored highly, and as the in vivo effect of the essential oil on convulsions seems to be only moderate, the results of the in silico study seem not to contradict results obtained by in vivo models. Thus, we can say that molecular docking might be a useful tool in initial screening for active constituents of natural product mixtures and the potential prediction of their activity in models in vivo.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Besides psyche-related symptoms, patients with anxiety disorders can have a large number of somatic symptoms as well. Although the treatment of these disorders is mainly focused on resolving their mental component, one cannot neglect the need for the treatment of accompanying somatic symptoms. Melissa officinalis L. (lemon balm), in various formulations, has been extensively used as an ethnomedicinal remedy for the treatment of different psyche-related symptoms, and its use is considered relatively safe. AIM OF THE STUDY In the present study, the activity of M. officinalis (MO) essential oil was evaluated in several in vitro and in vivo models mimicking or involving anxiety-related somatic symptoms. MATERIALS AND METHODS To address the effect of MO essential oil on the gastrointestinal and heart-related symptoms accompanying anxiety disorders, in vitro models were utilized that follow the function of the isolated mouse ileum and atria tissues, respectively, after exposure to MO essential oil. Effects of MO essential oil on BALB/c mice motor activity was estimated using the open field, rota-rod, and horizontal wire tests. Additionally, the essential oil was assayed for its potential in inhibiting acetylcholinesterase activity. RESULTS The performance of mice treated with 25 mg/kg of the oil showed a statistically significant decrease in the motor impairment arising from acute anxiety (open field test), while there was a prolonged latency and a reduction of the frequency of falling from a rotating rod and/or a horizontal wire (signs of muscle weakness/spasms). Concentrations of the essential oil higher than 1 μg/mL were found to inhibit both spontaneous and induced ileum contractions. Moreover, the essential oil and citronellal were found to decrease isolated mouse atria contraction frequency, as well as contraction force. However, the oil was found to be a very weak acetylcholinesterase inhibitor. CONCLUSION The modulation of anxiety-related symptoms by the oil was found not to be mediated through the inhibition of the acetylcholinesterase, nonetheless, the mechanistic studies involving the ileum and cardiac tissues, revealed that the activity of MO and citronellal might be related to the modification of either voltage-gated Ca2+ channels or muscarinic receptors. Mice locomotion, balance, and muscle strength were not impacted by the essential oil; however, its main constituent, citronellal, was found to exert a certain degree of muscle function inhibition. All these results suggest that the activity of MO essential oil arises from synergistic and/or antagonistic interactions of its constituents, and is not completely dependent on the oil's main constituent.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE There are plant species used in the Mexican traditional medicine for the empirical treatment of anxiety and depression. AIM OF THE STUDY This work assessed the prevalence of self-medication with medicinal plants and the prevalence of the concomitant use of prescribed psychiatric drugs and medicinal plants for treating symptoms associated with anxiety and depression during the Covid-19 lockdown in Mexico. MATERIALS AND METHODS The suspected adverse reactions associated with drug-herb interactions were assessed. The factors associated with self-medication, the concomitant use of herb-drug combinations, and the presence of adverse reactions due their combined use is also reported. The study was descriptive and cross-sectional using an online questionnaire conducted among population with symptoms associated with anxiety and depression (n = 2100) from seven states of central-western Mexico. RESULTS The prevalence of the use of herbs (61.9%) and the concomitant use of drug-herb combinations (25.3%) were associated with being diagnosed with mental illness [OR:2.195 (1.655-2.912)] and the use of psychiatric medications [OR:307.994 (178.609-531.107)], respectively. The presence of adverse reactions (n = 104) by the concomitant use of drug-herb combinations was associated with being unemployed [p = 0.004, OR: 3.017 (1.404-6.486)]. CONCLUSION Health professionals should be aware if their patients concomitantly use medicinal plants and psychiatric drugs. Public health campaigns should promote the possible adverse reactions that might produce the concomitant use of drug-herb combinations for mental illnesses.

Abstract
BACKGROUND Self-medication practice (SMP) is widely adopted among residents of such countries as Bangladesh. However, the major determinants of SMP have only scarcely been evaluated. Therefore, this cross-sectional study aimed to fill this knowledge gap by assessing the prevalence and determining factors of SMP. METHODS A convenience sample of individuals residing in Savar (Dhaka, Bangladesh) >16 years of age and suffering from an illness >2 months underwent face-to-face interviews during January-February, 2019. RESULTS Among 520 interviewees fulfilling entry criteria, the prevalence of SMP was reported as 60.2%. Drug shops, previous knowledge or prescription, and consulting with peers (friends or relatives) were the most sought sources of SMP, whereas simple illness, higher consulting fees, unsatisfactory health-care services, and delayed access were reported as the motives. From the regression analysis, the sociodemographic risk factors of SMP were reported as being older (compared to <18 years), married, illiterate (compared to having higher education), having engaged in any occupation (ie, service, business, homemaker, and others compared to student), and suffering from chronic illness. CONCLUSION SMP is highly prevalent and exhibits significant socioeconomic determinants. Development of proper health care-access systems and public education should be implemented to reduce the rate of SMP.

Abstract
Balkan Peninsula is one of the most important biodiversity centers in Europe. Despite that, the usage of plant species in the traditional medicine of some Balkan regions remained largely unexplored in the past. This study aimed to collect and document data on the traditional use of medicinal plants in Pčinja district in South-Eastern Serbia, which is among the least developed regions in Serbia. Also, comparison with data collected by Dr. Jovan Tucakov, in a book called Herbal therapy was conducted. The survey was carried out using semi-structured interviews and 113 informants were interviewed. Quantitative ethnobotany factors were calculated, allowing us discussing the results. The informants reported data on 86 medicinal plants belonging to 43 families in Pčinja district. Lamiaceae, Asteraceae, and Rosaceae were the dominant locally used families. The species with the highest number of use reports were Mentha piperita, Matricaria chamomilla, and Hypericum perforatum. Gastrointestinal ailments, respiratory problems and skin diseases were the most frequently reported indications. Usually, the administration was primarily oral followed by topical applications. Leaves were dominantly exploited plant parts and the most frequent preparation form was infusion. Medicinal plants in Pčinja district are mainly used as a mode of primary health care for treating minor health issues. After comparing our results with the ones collected half a century ago by Dr. Jovan Tucakov we can conclude that plant species mentioned in our investigation previously had a much wider spectrum of application.

Abstract
Despite being renowned for its volatiles, the data on the toxicity of the essential oil of lemon balm (Melissa officinalis L., Lamiaceae) is rather limited compared to its solvent/water-soluble extractibles. In this study, the aerial parts essential oil of M. officinalis, with over 130 constituents identified herein, 26 of which detected for the first time, was investigated for acute oral toxicity in BALB/c mice. The oil, composed of predominantly monoterpene aldehydes, citronellal (21.2-21.8%), neral (17.8-18.4%), and geranial (22.9-23.5%), which were assayed in parallel with the oil in some tests, induced significant changes in animal behavior, as well as altered biochemical parameters reflecting liver and kidney functions. Different pathological changes in the stomach, duodenum, liver, and kidneys were detected when the oil was administered in doses higher than 1 g kg-1. A depletion in the liver/kidney antioxidant capacities and an increased rate of lipid peroxidation was noted for animals treated with lemon balm oil. The calculated value of the oral LD50 in BALB/c mice (2.57 g kg-1) infers that the essential oil is only moderately toxic.

Abstract
Utilization of herbal products (HPs) is a common practice in the traditional medicine of people from southeastern Serbia. In this study, we focused on the usage of HPs as a self-medication practice among patients diagnosed with a mental illness, by aiming to ascertain the usage prevalence, the identity of the main plant taxa utilized, their formulations and target symptoms. This was accomplished through a cross-sectional study of psychiatric outpatients, conducted in the Clinic for Mental Health Protection in Niš, and which included a questionnaire on HP utilization and a non-structured psychiatric interview. Typically, single, middle-aged males, with a secondary education degree, utilized Matricaria chamomilla and/or Melissa officinalis in a form of an infusion (tea) for relieving anxiety and psychotic symptoms. In some cases, adverse effects were noted when HPs were used in combination with prescribed psychotropic medications. Our and previous results urge a thorough evaluation of possible benefits and/or harmful interactions of HP with standard medication in the treatment of psychiatric patients.

Hepatotoxicity of Herbal Supplements Mediated by Modulation of Cytochrome P450. Int J Mol Sci 2017; 18:ijms18112353.

Abstract
Herbal supplements are a significant source of drug-drug interactions (DDIs), herb-drug interactions, and hepatotoxicity. Cytochrome P450 (CYP450) enzymes metabolize a large number of FDA-approved pharmaceuticals and herbal supplements. This metabolism of pharmaceuticals and supplements can be augmented by concomitant use of either pharmaceuticals or supplements. The xenobiotic receptors constitutive androstane receptor (CAR) and the pregnane X receptor (PXR) can respond to xenobiotics by increasing the expression of a large number of genes that are involved in the metabolism of xenobiotics, including CYP450s. Conversely, but not exclusively, many xenobiotics can inhibit the activity of CYP450s. Induction of the expression or inhibition of the activity of CYP450s can result in DDIs and toxicity. Currently, the United States (US) Food and Drug Administration does not require the investigation of the interactions of herbal supplements and CYP450s. This review provides a summary of herbal supplements that inhibit CYP450s, induce the expression of CYP450s, and/or whose toxicity is mediated by CYP450s.
