Natural product-derived therapies for treating drug-resistant epilepsies: From ethnopharmacology to evidence-based medicine. JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116740. [PMID: 37315641 DOI: 10.1016/j.jep.2023.116740] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 05/17/2023] [Accepted: 06/04/2023] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Epilepsy is one of the most prevalent neurological human diseases, affecting 1% of the population in all age groups. Despite the availability of over 25 anti-seizure medications (ASMs), which are approved in most industrialized countries, approximately 30% of epilepsy patients still experience seizures that are resistant to these drugs. Since ASMs target only limited number of neurochemical mechanisms, drug-resistant epilepsy (DRE) is not only an unmet medical need, but also a formidable challenge in drug discovery. AIM In this review, we examine recently approved epilepsy drugs based on natural product (NP) such as cannabidiol (CBD) and rapamycin, as well as NP-based epilepsy drug candidates still in clinical development, such as huperzine A. We also critically evaluate the therapeutic potential of botanical drugs as polytherapy or adjunct therapy specifically for DRE. METHODS Articles related to ethnopharmacological anti-epileptic medicines and NPs in treating all forms of epilepsy were collected from PubMed and Scopus using keywords related to epilepsy, DRE, herbal medicines, and NPs. The database clinicaltrials.gov was used to find ongoing, terminated and planned clinical trials using herbal medicines or NPs in epilepsy treatment. RESULTS A comprehensive review on anti-epileptic herbal drugs and natural products from the ethnomedical literature is provided. We discuss the ethnomedical context of recently approved drugs and drug candidates derived from NPs, including CBD, rapamycin, and huperzine A. Recently published studies on natural products with preclinical efficacy in animal models of DRE are summarized. Moreover, we highlight that natural products capable of pharmacologically activating the vagus nerve (VN), such as CBD, may be therapeutically useful to treat DRE. CONCLUSIONS The review highlights that herbal drugs utilized in traditional medicine offer a valuable source of potential anti-epileptic drug candidates with novel mechanisms of action, and with clinical promise for the treatment of drug-resistant epilepsy (DRE). Moreover, recently developed NP-based anti-seizure medications (ASMs) indicate the translational potential of metabolites of plant, microbial, fungal and animal origin.

Anticonvulsant effects of isopimpinellin and its interactions with classic antiseizure medications and borneol in the mouse tonic-clonic seizure model: an isobolographic transformation. Pharmacol Rep 2023; 75:1533-1543. [PMID: 37821793 PMCID: PMC10661746 DOI: 10.1007/s43440-023-00532-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 09/14/2023] [Accepted: 09/15/2023] [Indexed: 10/13/2023]
Abstract
BACKGROUND Overwhelming evidence indicates that some naturally occurring coumarins and terpenes are widely used in folk medicine due to their various therapeutic effects affecting the brain. Antiseizure medications (ASMs) are the principal treatment option for epilepsy patients, although some novel strategies based on naturally occurring substances are intensively investigated. This study was aimed at determining the influence of isopimpinellin (ISOP-a coumarin) when administered either separately or in combination with borneol (BOR-a monoterpenoid), on the antiseizure potencies of four classic ASMs (carbamazepine (CBZ), phenytoin (PHT), phenobarbital (PB), and valproate (VPA)) in the mouse model of maximal electroshock-induced (MES) tonic-clonic seizures. MATERIALS Tonic-clonic seizures were evoked experimentally in mice after systemic (ip) administration of the respective doses of ISOP, BOR, and classic ASMs. Interactions for two-drug (ISOP + a classic ASM) and three-drug (ISOP + BOR + a classic ASM) mixtures were assessed isobolographically in the mouse MES model. RESULTS ISOP (administered alone) had no impact on the anticonvulsant potencies of four classic ASMs. Due to the isobolographic transformation of data, the combination of ISOP + VPA exerted an antagonistic interaction, whereas the two-drug mixtures of ISOP + CBZ, ISOP + PHT, and ISOP + PB produced additive interactions in the mouse MES model. The three-drug combinations of ISOP + BOR with CBZ and PHT produced additive interactions, while the three-drug combinations of ISOP + BOR with PB and VPA exerted synergistic interactions in the mouse MES model. CONCLUSIONS The most intriguing interaction was that for ISOP + VPA, for which the addition of BOR evoked a transition from antagonism to synergy in the mouse MES model.

Abstract
BACKGROUND Traditional and complementary medicine (T&CM) is highly utilised and draws on traditional knowledge (TK) as evidence, raising a need to explore how TK is currently used. OBJECTIVES Examine criteria used to select, evaluate and apply TK in contemporary health contexts. METHODS Systematic search utilising academic databases (AMED, CINAHL, MEDLINE, EMBASE, SSCI, ProQuest Dissertations Theses Global), Trip clinical database and Google search engine. Citations and reference lists of included articles were searched. Reported use of TK in contemporary settings was mapped against a modified 'Exploration-Preparation-Implementation-Sustainment' (EPIS) implementation framework. RESULTS From the 54 included articles, EPIS mapping found TK is primarily used in the Exploration phase of implementation (n = 54), with little reporting on Preparation (n = 16), Implementation process (n = 6) or Sustainment (n = 4) of TK implementation. Criteria used in selection, evaluation and application of TK commonly involved validation with other scientific/traditional evidence sources, or assessment of factors influencing knowledge translation. DISCUSSION One of the difficulties in validation of TK (as a co-opted treatment) against other evidence sources is comparing like with like as TK often takes a holistic approach. This complicates further planning and evaluation of implementation. CONCLUSION This review identifies important criteria for evaluating current and potential contemporary use of TK, identifying gaps in research and practice for finding, appraising and applying relevant TK studies for clinical care.

Pharmacometabolic Effects of Pteryxin and Valproate on Pentylenetetrazole-Induced Seizures in Zebrafish Reveal Vagus Nerve Stimulation. Cells 2023; 12:1540. [PMID: 37296660 PMCID: PMC10252891 DOI: 10.3390/cells12111540] [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: 04/17/2023] [Revised: 05/31/2023] [Accepted: 06/01/2023] [Indexed: 06/12/2023] Open
Abstract
Zebrafish (Danio rerio) assays provide a versatile pharmacological platform to test compounds on a wide range of behaviors in a whole organism. A major challenge lies in the lack of knowledge about the bioavailability and pharmacodynamic effects of bioactive compounds in this model organism. Here, we employed a combined methodology of LC-ESI-MS/MS analytics and targeted metabolomics with behavioral experiments to evaluate the anticonvulsant and potentially toxic effects of the angular dihydropyranocoumarin pteryxin (PTX) in comparison to the antiepileptic drug sodium valproate (VPN) in zebrafish larvae. PTX occurs in different Apiaceae plants traditionally used in Europe to treat epilepsy but has not been investigated so far. To compare potency and efficacy, the uptake of PTX and VPN into zebrafish larvae was quantified as larvae whole-body concentrations together with amino acids and neurotransmitters as proxy pharmacodynamic readout. The convulsant agent pentylenetetrazole (PTZ) acutely reduced the levels of most metabolites, including acetylcholine and serotonin. Conversely, PTX strongly reduced neutral essential amino acids in a LAT1 (SLCA5)-independent manner, but, similarly to VPN specifically increased the levels of serotonin, acetylcholine, and choline, but also ethanolamine. PTX dose and time-dependent manner inhibited PTZ-induced seizure-like movements resulting in a ~70% efficacy after 1 h at 20 µM (the equivalent of 4.28 ± 0.28 µg/g in larvae whole-body). VPN treated for 1 h with 5 mM (the equivalent of 18.17 ± 0.40 µg/g in larvae whole-body) showed a ~80% efficacy. Unexpectedly, PTX (1-20 µM) showed significantly higher bioavailability than VPN (0.1-5 mM) in immersed zebrafish larvae, possibly because VPN in the medium dissociated partially to the readily bioavailable valproic acid. The anticonvulsive effect of PTX was confirmed by local field potential (LFP) recordings. Noteworthy, both substances specifically increased and restored whole-body acetylcholine, choline, and serotonin levels in control and PTZ-treated zebrafish larvae, indicative of vagus nerve stimulation (VNS), which is an adjunctive therapeutic strategy to treat refractory epilepsy in humans. Our study demonstrates the utility of targeted metabolomics in zebrafish assays and shows that VPN and PTX pharmacologically act on the autonomous nervous system by activating parasympathetic neurotransmitters.

Abstract
The methanol extract of Doronicum pardalianches L. was fractionated using n-hexane, chloroform, and ethyl acetate to evaluate their cholinesterase (ChE) inhibitory activity via modified Ellman's method. It was perceived that only the ethyl acetate fraction was active toward acetylcholinesterase (AChE) with IC50 value of 172.21 µg/mL. Also, all fractions showed no butyrylcholinesterase (BChE) inhibitory activity. The ethyl acetate fraction was also investigated for its neuroprotectivity and metal chelating ability (Zn2+, Fe2+, and Cu2+) which demonstrated desired activity. Phytochemical analysis of the ethyl acetate fraction led to isolation and identification of formononetin 7-O-β-D-glucopyranoside which has not been previously reported for this plant.

Abstract
Xanthotoxin (XAT) is a natural furanocoumarins, a bioactive psoralen isolated from the fruit of the Rutaceae plant Pepper, which has received increasing attention in recent years due to its wide source and low cost. By collecting and compiling literature on XAT, the results show that XAT exhibits significant activity in the treatment of various diseases, including neuroprotection, skin repair, osteoprotection, organ protection, anticancer, antiinflammatory, antioxidative stress and antibacterial. In this paper, we review the pharmacological activity and potential molecular mechanisms of XAT for the treatment of related diseases. The data suggest that XAT can mechanistically induce ROS production and promote apoptosis through mitochondrial or endoplasmic reticulum pathways, regulate NF-κB, MAPK, JAK/STAT, Nrf2/HO-1, MAPK, AKT/mTOR, and ERK1/2 signaling pathways to exert pharmacological effects. In addition, the pharmacokinetics properties and toxicity of XAT are discussed in this paper, further elucidating the relationship between structure and efficacy. It is worth noting that data from clinical studies of XAT are still scarce, limiting the use of XAT in the clinic, and in the future, more in-depth studies are needed to determine the clinical efficacy of XAT.

Abstract
Bountiful expression of bioactivity of phytochemicals obtained from spice crops like coriander gifts them the label of being natural antioxidants. It is well-accepted and time-tested towards contributing to human wellbeing. The accomplishment of coriander production is fundamentally influenced by genetic, agroclimatic, and agronomic factors. Despite the fact that there are very restricted options to manage the first two factors, the third one is apparently imperative to arbitrate as far as the elevated yield and enhanced quality are concerned. On the other hand, an indomitable, object-oriented, controlled agrotechnological and biotechnological intervention can also contribute towards better yield and quality of coriander. There are several accounts of the successful use of such technologies in order to genetically improve the qualitative and quantitative indicators of coriander. However, often these areas are not comprehensively explored and utilized. In that context, the present review highlights the botanical features, origin and distribution, multi-dimensional importance, pre- and post-harvest crop management, phytochemical production, and germplasm conservation, including the in vitro-based regeneration methods along with molecular marker-based biotechnological and omics approaches attempted in coriander until date. In addition, the possibility of the yet-to-be-explored agri-biotechnological methods and their potential for genetic improvement of this crop has also been reviewed in this appraisal. KEY POINTS: • Coriander, used both as an herb and spice, is popular in the pharmaceutical and culinary industries. • The current review provides insight into agrotechnological and biotechnological interventions for better yield and quality. • Provides novel ideas to harness the comprehensive qualitative and quantitative genetic improvement based on the potential use of promising biotechnological tools and techniques.

Abstract
Simple Summary This research aims to investigate the effects of coriander plants on human emotions and physiological activities. The results showed coriander plants could significantly reduce the angry sub-scores, alpha amylase and amino acids (arginine, proline, histidine, and taurine) concentrations in saliva. Theta (4–8 Hz) band activity of the cerebral cortex was significantly enhanced. Moreover, taurine significantly positively correlated with anger and negatively correlated with vigor. All the results signified that coriander plant could influence the activity of brain electrophysiological and salivary secretion through its VOCs to improve people’s negative emotions. This study will provide a theoretical basis for the living coriander plants have some therapeutic effect on the human psychological state. Abstract Coriander is a popular herb with versatile applications. However, the current research about coriander medicinal values have been mainly focusing on its extracts while lacking in the relationship between living coriander plants and emotion. Therefore, this study aims to investigate the effects of coriander plants on human emotions and physiological activities. The results showed that the main Volatile organic compounds (VOCs) of coriander plants were 2-ethyl-1-hexanol, d-limonene, eucalyptol, benzyl alcohol, Isophorone, dimethyl glutarate, α-terpineol, styrene, methyl methacrylate, α-pinene. Coriander plants could significantly reduce the angry sub-scores, alpha amylase and amino acids (arginine, proline, histidine, and taurine) concentrations in saliva. Theta (4–8 Hz) band activity of the cerebral cortex was significantly enhanced. Moreover, taurine significantly positively correlated with anger and negatively correlated with vigor.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Species of the genera Hieracium and Pilosella have been used in folk medicine for centuries in many parts of the world. The most wiedly used species is P. officinarum Vaill., included in the British and French Pharmacopoeias and sold as part of different commercial products. AIM OF THE STUDY This review critically appraises the state-of-art of ethnopharmacology, specialised metabolites, bioactivities, and toxicity of members of Hieracium and Pilosella. Thus, gaps in scientific knowledge can be identified, also focusing on the development of products with pharmacological applications. MATERIALS AND METHODS Literature data of Hieracium and Pilosella species were mainly retrieved using different electronic databases such as Web of Science, Google Scholar, SciFinder, and PubMed. Other electronic resources included worldwide databases on ethnobotany, ethnopharmacology, and phytochemistry as well as government reports. Additionally, ancient texts and local information such as PhD and MSc theses, and books were consulted. RESULTS A comprehensive analysis of the above mentioned sources revealed that only 34 out of the about 850 described species within the genera Hieracium and Pilosella have been reported in the context of traditional medicinal and ethnobotanical knowledge. The most often mentioned species is P. officinarum which has been widely used due to its diuretic effects. Other popular uses of Hieracium and Pilosella species include the treatment of skin, gastric, and intestinal diseases as well as respiratory and vascular ailments. Moreover, taxa of the two genera have been used as antiobiotics, antiseptics, antidiabetics, tonics, antiepileptics, antiphlogistics, emetics, wound healing drugs, astringents, haemostatics, and detoxificants. Finally, uses as a wild vegetable, fodder, plant for hunting and for charming rituals have also been mentioned. Phytochemical research revealed a richness in phenolic compounds and flavonoids. Moreover, coumarins, sesquiterpene lactones, terpenoids, and phytosterols were found in Hieracium and Pilosella. Experimental research conducted to support traditional uses mainly include in vitro tests, while assays based on in vivo models (including humans) are rather limited. Also, the vast majority of the studies did not identify the compounds responsible for the detected bioactivities. These established bioactivities include antidiabetic, anti-inflammatory, antibacterial, antimycotic, antiviral, cytotoxic and antiproliferative, diuretic, gastroprotective, antiepileptic, hypotensive, anti-obesity, arthropodicidal, and skin rejuvenating activities. Finally, limited toxicity studies have been conducted on members of Hieracium and Pilosella. CONCLUSION Taxa belonging to Hieracium and Pilosella have been confirmed to exert diuretic, anti-inflammatory, and antimicrobial effects, which is in line with their long traditional use. Moreover, the above mentioned fields of application hint to the most promising routes for the development of new marketable products. Nonetheless, additional data from an in-depth research on bio-active specialised metabolites such as sesquiterpenoids, sesquiterpene lactones, and coumarines, their bioactivities and toxicity, and their biosynthesis are still warranted.

Efficacy and tolerability of hydroalcoholic extract of Paeonia officinalis in children with intractable epilepsy: An open-label pilot study. Epilepsy Res 2021; 176:106735. [PMID: 34388412 DOI: 10.1016/j.eplepsyres.2021.106735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 07/18/2021] [Accepted: 07/27/2021] [Indexed: 10/20/2022]
Abstract
Despite a wide range of medications available to control epilepsy, seizures in more than 30 % of patients remain uncontrolled. However, in traditional medicine, Paeonia officinalis (P. officinalis), a native perennial herb of Southern Europe and Western Asia, has been used for an anticonvulsant effect for over 2000 years globally. In an open-label pilot study implemented on 30 children with intractable epilepsy aged 1-14 years, the hydroalcoholic extract of P. officinalis was administered. This study's purpose was to assess the efficacy and tolerability of the P. officinalis extract as an adjunct therapy to a patient's antiseizure medications in reducing the frequency and duration of the seizures in childhood intractable epilepsy. The mean frequency of seizures decreased significantly during treatment with the P. officinalis extract (P < 0.05). At the end of the intervention, 62.5 % and 36.7 % of the patients showed a≥50 % and a≥75 % reduction in seizure frequency, respectively. Regarding safety and tolerability, no serious adverse events occurred during the trial, although restlessness was reported in one child and the other children who experienced constipation, stopped treatment. The results show that the P. officinalis root extract was well tolerated and has contributed to a significant improvement in seizure control in children with medically intractable epilepsy. This trial was registered with the Iranian Registry of Clinical Trials (www.irct.ir; registration number: IRCT20131125015533N2.

Abstract
The understanding of epilepsy has been in progressive evolution since Antiquity, with scientific advances culminating in the last few decades. Throughout history, epilepsy was plagued by mystical misconceptions involving either demonic possessions, witchcraft, or divine interventions. This has frequently altered or even halted any real progress in its scientific understanding or its social perception. This metaphysical context is also at the core of the stigma revolving around this condition, some of which still lingering today. This review explores the origins of these mystical beliefs, and describes the chronological evolution of epilepsy from mysticism to science across different civilizations and eras.

Abstract
COVID-19, the disease caused by SARS-CoV-2, has been declared as a global pandemic. Traditional medicinal plants have long history to treat viral infections. Our in silico approach suggested that unique phytocompounds such as emodin, thymol and carvacrol, and artemisinin could physically bind SARS-CoV-2 spike glycoproteins (6VXX and 6VYB), SARS-CoV-2 B.1.351 South Africa variant of Spike glycoprotein (7NXA), and even with ACE2 and prevent the SARS-CoV-2 binding to the host ACE2, TMPRSS2 and neutrapilin-1 receptors. Since Chloroquine has been looked as potential therapy against COVID-19, we also compared the binding of chloroquine and artemisinin for its interaction with spike proteins (6VXX, 6VYB) and its variant 7NXA, respectively. Molecular docking study of phytocompounds and SARS-CoV-2 spike protein was performed by using AutoDock/Vina software. Molecular dynamics (MD) simulation was performed for 50ns. Among all the phytocompounds, molecular docking studies revealed lowest binding energy of artemisinin with 6VXX and 6VYB, with Etotal -10.5 KJ mol-1 and -10.3 KJ mol-1 respectively. Emodin showed the best binding affinity with 6VYB with Etotal -8.8 KJ mol-1and SARS-CoV-2 B.1.351 variant (7NXA) with binding energy of -6.4KJ mol-1. Emodin showed best interactions with TMPRSS 2 and ACE2 with Etotal of -7.1 and -7.3 KJ mol-1 respectively, whereas artemisinin interacts with TMPRSS 2 and ACE2 with Etotal of -6.9 and -7.4 KJ mol-1 respectively. All the phytocompounds were non-toxic and non-carcinogenic. MD simulation showed that artemisinin has more stable interaction with 6VYB as compared to 6VXX, and hence proposed as potential phytochemical to prevent SARS-CoV-2 interaction with ACE-2 receptor.

Abstract
Leonurus cardiaca L. (motherwort) is a perennial herb, native to Asia and southeastern Europe, with widespread global occurrence in present days. The plant was historically used as cardiotonic and for treating gynaecological afflictions (such as amenorrhea, dysmenorrhea, menopausal anxiety, or postpartum depression). Although its use in oriental and occidental medicine is relatively well documented, the recent progress registered raises the need for an update of the Medicines Agency assessment report on Leonurus cardiaca L., herba (2010). The current study presents the progress made within the 2010-2018 timeframe regarding the potential applications and scientific evidences supporting the traditional use of motherwort, in the same time suggesting future research opportunities.

Abstract
OBJECTIVES Assess whether an ancient text on herbal medicine accurately characterizes a class of herbal diuretics. DESIGN The Greek text of Dioscorides De materia medica was assessed for herbs stated to have diuretic activity, and then modern research was sought to determine how accurate the ancient assessment of these herbs was. RESULTS Of the 105 plants cited as having diuretic activity by Dioscorides, 56 (53.3%) genuses are confirmed as being diuretic in animal or human research. For another 38 (36.2%) genuses, no research related to diuresis could be identified. Six (5.7%) genuses had mixed results in modern research, whereas a mere 5 (4.8%) genuses were shown to not have diuretic activity. Considering the 67 genuses that were investigated, 56 (83.6%) were confirmed. CONCLUSION This analysis confirms that Dioscorides was accurate in determining the diuretic nature of herbs, raising the possibility that he was right about other therapeutic suggestions concerning herbs he made. For the remaining herbs that have not been assessed for diuretic effect, it is not yet known if Dioscorides was accurate. Our findings suggest that the 38 herbs Dioscorides categorized as diuretics that have not been studied for diuretic function are candidates for research in this regard.

Abstract
Although some widespread, native cow parsnips (Heracleum L. spp., Apiaceae) had broad medicinal and culinary applications throughout history, the knowledge about their volatile constituents is insufficient. This work investigates the composition and bioactivities of H. sphondylium L. (HSPH), H. sibiricum L. (HSIB) and H. montanum Schleich. ex Gaudin (HMON) essential oils. The composition was tested by GC and GC-MS. (Z)-β-Ocimene was the most abundant in HSPH (28.9%) and HMON (20.4%) root oils, while in HSIB root oil, β-pinene (26.2%), methyl eugenol (22.3%) and elemicin (25.6%) prevailed. Leaf and flower oils were dominated by various sesquiterpenes (germacrene D, β-sesquiphellandrene, (E)-β-farnesene and/or (E)-caryophyllene) and/or phenylpropanoids (apiole, methyl eugenol, elemicin and/or (Z)-isoelemicin). Octyl acetate (57.5-67.1%) was the main constituent of all fruit oils. The antimicrobial activity was screened by a microdilution method against eight bacteria and eight fungi. The strongest antimicrobial effect, in several cases better than the activity of antibiotics, was shown by HSPH (MICs = 0.12-3.30 mg mL-1) and HMON (MICs = 0.10-1.30 mg mL-1) flower oils against bacteria, and HSIB fruit oil against fungi (MICs = 0.15-0.40 mg mL-1). The MTT test revealed that the oils were not or weakly cytotoxic against human malignant HeLa, LS174 and/or A549 cells (except HSPH root oil; IC50 = 5.72-24.31 μg mL-1) and that tested oils were not toxic against human normal MRC-5 cells (at 200.00 μg mL-1). Significant activity observed against microorganisms that are the common cause of foodborne diseases, food contamination and/or hospital-acquired infections justifies certain traditional uses of the investigated plants and represents a good basis for further research of these Heracleum oils.

Abstract
This article discusses etiology, pathogenesis, symptoms, and treatment of epilepsy, as described in Charaka Samhitā (translation: Charaka's Compendium) and Sushruta Samhitā, the two core texts of Ayurveda, an ancient system of medicine. Ayurveda emphasized amnesia and loss of consciousness as core features of epileptic seizures (Sanskrit: apasmar; translation: apa negation, smaran memory) and recognized that seizures occur due to a disturbance in brain function or flow of "humors" to the brain. Semiology of various seizure types was well described. Epilepsy was attributed to both internal and multiple exogenous factors. Treatment of epilepsy with formulations of naturally occurring substances, their compounding and use, is described in remarkable detail. Lifestyle modifications to protect people with epilepsy are also documented. Cognitive comorbidities of epilepsy were recognized. Although none of the Ayurveda formulations have any empirical evidence supporting their safety or efficacy in the treatment of epilepsy, studies are needed to generate relevant evidence, to recognize their hazards, and to integrate traditional and complementary systems of medicine with modern health care in an informed and safe manner.

Abstract
Coriandrum sativum (C. sativum) or coriander is one of the most popularly used spices in culinary worldwide, and its medicinal values has been recognized since ancient time. C. sativum contains bioactive phytochemicals that are accounted for a wide range of biological activities including antioxidant, anticancer, neuroprotective, anxiolytic, anticonvulsant, analgesic, migraine-relieving, hypolipidemic, hypoglycemic, hypotensive, antimicrobial, and antiinflammatory activities. The major compound, linalool, abundantly found in seeds is remarked for its abilities to modulate many key pathogenesis pathways of diseases. Apart from the modulating effects, the potent antioxidant property of the C. sativum provides a key mechanism behind its protective effects against neurodegenerative diseases, cancer, and metabolic syndrome. This review shed light on comprehensive aspects regarding the therapeutic values of the C. sativum, which indicate its significance of being a promising functional food for promoting the well-being in the era of aging and lifestyle-related diseases.

Abstract
Background: Lippia citriodora Kunth is one of the Iranian traditional medicines for the treatment of convulsive disorders. The goal of this study is to investigate the anticonvulsant activity of the plant's leave ethanolic extract against electro- and chemoconvulsant-induced seizures in mice. Methods: The anticonvulsant activity of the extract (200, 400, 800 mg/kg, per os, p.o.) was investigated in pentylenetetrazole (PTZ) and maximal electroshock (MES)-induced seizures in mice. Diazepam (1 mg/kg) and phenytoin (25 mg/kg) intraperitoneally (i.p.) were used as reference drugs. In addition, for investigating the role of GABAergic system, flumazenil (2 mg/kg, i.p.) was also injected before L. citriodora. Results: The extract had not any toxicity and significantly decreased the duration and increased the latency of the seizures induced by PTZ (90 mg/kg). In the MES test, L. citriodora displayed statistically significant reduction in hind limb tonic extension duration in a nondose-dependent manner. Flumazenil reversed the anticonvulsant activity of the plant's extract in the PTZ model. Conclusions: The results propose that L. citriodora leave ethanolic extract has anticonvulsant activity against convulsive disorders. It seems that this plant's extract generates its antiseizure effect through GABAergic system potentiation. Further studies will be needed in order to investigate the exact mechanisms of it. Moreover, one may conclude that the present results are in accordance with the positive effect of L. citriodora extract to treat convulsion mentioned in old Iranian literature.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pedanius Dioscorides has been praised as the father of Pharmacy and his work Περί Ύλης Ιατρικής - De Materia Medica, served as the reference Pharmacy manual for almost twenty centuries. Though greatly celebrated among botanists of all ages' indisputable identification of numerous Dioscorides plants is still in quest. Present essay aspires to resolute the botanical status of the Umbelliferae (Apiacae) plants, through data extraction and recombination from a 7th century manuscript. MATERIALS AND METHODS Codex Neapolitanus Graecus 1 (CN) is the fundamental study material. From this source were extracted data, both from text and figures, in relation to plant nomenclature, habitat, morphology and geographical distribution; consequently those data were translated into present botanical terminology and then recombined according to the Flora of Turkey and the East Aegean Islands covering the area that Dioscorides was born and studied. RESULTS, AND CONCLUSIONS All of the 40 CN plants indicated as Umbelliferae, presented a substantially documented identification. For 19 of them a novel combination was indicated and 4 of them proved new pharmaceutical plants. Applied methodology generated a documented correspondence between CN entries and contemporary Umbelliferae taxa nomenclature forming thus a promising new systematic tool for the study of relevant sources.

[PMID: 26281720 PMCID: PMC4748402 DOI: 10.1016/j.biotechadv.2015.08.001] [Citation(s) in RCA: 1310] [Impact Index Per Article: 145.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2015] [Revised: 07/16/2015] [Accepted: 08/07/2015] [Indexed: 01/01/2023]
Abstract
Medicinal plants have historically proven their value as a source of molecules with therapeutic potential, and nowadays still represent an important pool for the identification of novel drug leads. In the past decades, pharmaceutical industry focused mainly on libraries of synthetic compounds as drug discovery source. They are comparably easy to produce and resupply, and demonstrate good compatibility with established high throughput screening (HTS) platforms. However, at the same time there has been a declining trend in the number of new drugs reaching the market, raising renewed scientific interest in drug discovery from natural sources, despite of its known challenges. In this survey, a brief outline of historical development is provided together with a comprehensive overview of used approaches and recent developments relevant to plant-derived natural product drug discovery. Associated challenges and major strengths of natural product-based drug discovery are critically discussed. A snapshot of the advanced plant-derived natural products that are currently in actively recruiting clinical trials is also presented. Importantly, the transition of a natural compound from a "screening hit" through a "drug lead" to a "marketed drug" is associated with increasingly challenging demands for compound amount, which often cannot be met by re-isolation from the respective plant sources. In this regard, existing alternatives for resupply are also discussed, including different biotechnology approaches and total organic synthesis. While the intrinsic complexity of natural product-based drug discovery necessitates highly integrated interdisciplinary approaches, the reviewed scientific developments, recent technological advances, and research trends clearly indicate that natural products will be among the most important sources of new drugs also in the future.

Abstract
Epilepsy is the most common chronic neurological disease, affecting about 1% of the world's population during their lifetime. Most people with epilepsy can attain a seizure-free life upon treatment with antiepileptic drugs (AEDs). Unfortunately, seizures in up to 30% do not respond to treatment. It is estimated that 90% of people with epilepsy live in developing countries, and most of them receive no drug treatment for the disease. This treatment gap has motivated investigations into the effects of plants that have been used by traditional healers all over the world to treat seizures. Extracts of hundreds of plants have been shown to exhibit anticonvulsant activity in phenotypic screens performed in experimental animals. Some of those extracts appear to exhibit anticonvulsant efficacy similar to that of synthetic AEDs. Dozens of plant-derived chemical compounds have similarly been shown to act as anticonvulsants in various in vivo and in vitro assays. To a significant degree, anticonvulsant effects of plant extracts can be attributed to widely distributed flavonoids, (furano)coumarins, phenylpropanoids, and terpenoids. Flavonoids and coumarins have been shown to interact with the benzodiazepine site of the GABAA receptor and various voltage-gated ion channels, which are targets of synthetic AEDs. Modulation of the activity of ligand-gated and voltage-gated ion channels provides an explanatory basis of the anticonvulsant effects of plant secondary metabolites. Many complex extracts and single plant-derived compounds exhibit antiinflammatory, neuroprotective, and cognition-enhancing activities that may be beneficial in the treatment of epilepsy. Thus, botanicals provide a base for target-oriented antiepileptic drug discovery and development. In the future, preclinical work should focus on the characterization of the effects of plant extracts and plant-derived compounds on well-defined targets rather than on phenotypic screening using in vivo animal models of acute seizures. At the same time, available data provide ample justification for clinical studies with selected standardized botanical extracts and plant-derived compounds.

Abstract
OBJECTIVE This paper addresses the challenge on how to obtain information from practitioners with experience in using medicinal plants. BACKGROUND Collecting information on medicinal uses of plants is very challenging; since botanical remedies are used within the context of multiple differing medical systems, practitioners differ in training from Western physicians and scientists, and active ingredients of botanicals vary with preparation method, growth, and harvest conditions. DESIGN/METHODS A model on how useful data on safety and efficacy can be obtained from botanical practitioners is presented, based on methods developed by the association of anthroposophic physicians in Europe, a system of integrative medicine which includes the use of botanicals and is practiced mostly by medical doctors. RESULTS Decades of experience by hundreds of practitioners are summarized and made accessible in a manual, which alphabetically lists the most commonly used botanicals and describes the most successful therapeutic experiences which could be confirmed by several of the contributing practitioners. CONCLUSIONS/RELEVANCE This approach of continuous, multilingual systematic collection of successful therapeutic experiences within a community of practitioners with similar goals and a common therapeutic framework can be used not only for the training of successful future botanical practitioners, but also for helping to identify promising botanicals for scientific research and to further their development, and could support their official registration with governing bodies in countries of their use.

Abstract
Botanicals are increasingly used by people with epilepsy worldwide. However, despite abundant preclinical data on the anticonvulsant properties of many herbal remedies, there are very few human studies assessing safety and efficacy of these products in epilepsy. Additionally, the methodology of most of these studies only marginally meets the requirements of evidence-based medicine. Although the currently available evidence for the use of cannabinoids in epilepsy is similarly lacking, several carefully designed and well controlled industry-sponsored clinical trials of cannabis derivatives are planned to be completed in the next couple of years, providing the needed reliable data for the use of these products. The choice of the best botanical candidates with anticonvulsant properties and their assessment in well-designed clinical trials may significantly improve our ability to effectively and safely treat patients with epilepsy.

Review of Ethnobotanical, Phytochemical, and Pharmacological Study of Thymus serpyllum L. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:101978. [PMID: 26265920 PMCID: PMC4525464 DOI: 10.1155/2015/101978] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/06/2015] [Revised: 06/30/2015] [Accepted: 07/02/2015] [Indexed: 11/17/2022]
Abstract
Thymus serpyllum L. (wild thyme) is a perennial shrub, native to areas of northern and central Europe. Its aerial parts are most frequently used in ethnomedicine (mainly for treating illnesses and problems related to the respiratory and gastrointestinal systems), although recently its essential oils are becoming more popular as an important plant-derived product. The composition of these oils is affected by geographic region, the development stage of the plant, the harvest season, habitat, and climatic conditions. Wild thyme essential oil has an ever-growing number of uses in contemporary medicine due to its pharmacological properties: antioxidative, antimicrobial, and anticancerogenic activities. The antioxidative and antimicrobial properties of the essential oil are related to the synergistic and cumulative effect of its components. In terms of antitumor and cytotoxic activity, further research into the effects of essential oil is necessary, aimed at improving its cytotoxic effects, on the basis of which appropriate medicines can be formulated. Due to its pharmacological properties, the essential oil of wild thyme, a plant used in traditional medicine, represents an important natural resource for the pharmaceutical industry. In addition, it can be a source of natural antioxidants, nutritional supplements, or components of functional foods in the food industry.

Abstract
AbstractThe aim of the present study was to determine the anticonvulsant effects of xanthotoxin (8-methoxypsoralen) isolated from the fruit of Pastinaca sativa L. This plant is used in European traditional medicine, including Poland. For this purpose, high-performance counter-current chromatography was used. Different solvent systems, mixtures of n-heptane, ethyl acetate, methanol and water were tested in order to calculate partition coefficients. Finally, a mixture with the ratio of 1:1:1:1 (v/v/v/v), giving the K value = 0.92, was chosen as optimal. A rapid scale-up process from analytical to preparative was developed. Evaluation of the anticonvulsant action of xanthotoxin in the mouse maximal electroshock-induced seizure test revealed that it produced a clear-cut anticonvulsant action in mice, and the experimentally-derived median effective doses (ED50 values) ranged between 219 and 252 mg kg−1.

Abstract
Antiepileptic drugs used to treat epilepsy can cause severe, life threatening side effects. In Iranian traditional medicine, herbal remedies have been used for centuries to treat seizures. In this study, the five most important herbals in Iranian traditional medicine, namely Canon, al-Hawi, al-Abniah 'an Haqaeq al Adwia, Tuhfat al-Mu'minin, and Makhzan ul-Adwia, were searched for the term "sar-e", which means epilepsy, to identify the herbs used for treatment in ancient times. We also searched scientific literature for pharmacological evidence of their effectiveness. Twenty-five plants were identified as herbal remedies to treat epilepsy. Pharmacological data related to the antiepileptic activity of eleven of these plants exists. A large number of these plants which have not been investigated pharmacologically for antiepileptic activity would be good candidates for study in exploring new herbal anticonvulsant remedies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This analysis of documented medicinal plants of the Swiss Flora over the last two millennia provides a rich source of knowledge on earlier uses of plants and use patterns of the local flora. We ask which local plant species were used during different time periods of the last 2000 years and how the numbers of species and the use intensity of specific plant families, growth forms and habitats changed over time. MATERIALS AND METHODS Totally 25 herbals from the antiquity, monastic medicine, Renaissance, early modern era and the contemporary time as well as five recent ethnobotanical studies were considered. Use patterns were analysed with the Bayesian approach. RESULTS A total of 768 species, i.e. 32% of the vascular plants of the Swiss Flora have been documented as medicinal plants. Numbers increase until the monastic period (366 spp.) and the Renaissance (476) and remain relatively stable since then (modern and contemporary era: 477). But, 465 formerly documented species do not occur in the ethnobotanical studies and thus seem not to be used any more. Overall, 104 species are documented through all time periods. Archeophytes, trees and forest plants are generally overrepresented in herbals from all time periods while plants from above the timberline are generally underrepresented. Most widely used are the Lamiaceae and Apiaceae. CONCLUSION A constant body of medicinal plant knowledge in Switzerland exists since ancient time. This knowledge was always influenced by knowledge from neighboring countries and no "typical Swiss specialties" seem to exist. Medicinal plants are not randomly chosen from the available flora. Certain species are deliberately introduced others are neglected. This process, which is still ongoing, can be traced back with the help of herbals to the antiquity.

Abstract
Traditional knowledge uncovered by serious historical research may help to identify new therapeutic agents. It also plays a part in safety evaluation and drug regulation. So far, however, this way of gaining knowledge is very much neglected in the concept of evidence based medicine, which is in no way contradictory to traditional use. Thus, the true meaning of the word 'tradition' is described, while reliable historical sources are quoted. It is then shown how research into the traditional use of medicinal plants is able to reveal knowledge about efficacy and safety of natural products. Several examples successfully leading to new therapeutic options are given. It is then referred to the concept of 'social validation' developed by the Canadian medical historian John Crellin, who also established guidelines for respective research. Eventually, it is proposed to modify the list of evidence levels by inserting an evidence level 4b 'Traditional use in more than one regional cluster'.

Abstract
Epilepsy is a neurological disorder which has been recognized since antiquity. This paper evaluates the prophylactic and therapeutic remedies used by folk medicine to cure epilepsy in Italy. The data has been collected by reviewing written sources of physicians, ethnographers, folklorists between the late nineteenth and mid twentieth century. This approach leads to unearthing of 78 heterogeneous healing methods that have been divided into 16 (20%) magical, 20 (26%) religious and 42 (54%) natural remedies. The latter has been subdivided into 18 (43%) animal remedies, 17 (40%) plant remedies and 7 (17%) other remedies. Religious and magical remedies were used with the conviction that they would be able to provide recovery from epilepsy and to ward off evil spirits which had taken possession of the sick. Interestingly, the herbal remedies highlighted 12 (70%) plants that play or might play an important role with respect to the mechanisms that generate the epileptic seizures. This leads us to reconsider the historical significance of folk medicine, too often it is underestimated owing to its use of ineffective remedies, born of incompetence and superstition.
