JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2023; 19:44. [PMID: 37853377 PMCID: PMC10585756 DOI: 10.1186/s13002-023-00617-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 10/10/2023] [Indexed: 10/20/2023]
Abstract
BACKGROUND Traditional Polynesian medicine for children has been poorly documented, and few data are available on their efficacy and safety. In this context, the aim of this study was to identify traditional practices used for treating children and then assess the efficacy and safety of the most cited remedies by reviewing the literature. METHODS In 2022, a semi-structured survey was carried out on five islands from the Society archipelago (Bora Bora, Huahine, Moorea, Raiatea, and Tahiti). A total of 86 participants were interviewed including 19 experts in herbalism. A thorough literature review was performed on the most cited plant species to gather the relevant ethnobotanical, pharmacological, and clinical data of each remedy. RESULTS Participants mentioned using 469 remedies to treat 69 health disorders. The most represented health categories were digestive system, skin disorders, infectious diseases, and respiratory system. A total of 67 plant species (representing 731 use-reports) were mentioned and Annona muricata, Gardenia taitensis, and Hibiscus rosa-sinensis were the main plants reported. Regarding the safety of cited remedies, one plant (Microsorum grossum) showed high risk of toxicity, and its use should be avoided in infants and children. CONCLUSION Our survey confirms the importance of traditional medical practices for children in the Society Islands. A lack of data in children for most cited remedies demonstrate the need for more pharmacological and toxicological research on Polynesian medicinal plants. Finally, the potential risk of toxicity for some cited plant species reported calls for a better information of traditional medicine users and healers.

Mol Biol Rep 2022; 49:9543-9553. [PMID: 36053281 PMCID: PMC9515021 DOI: 10.1007/s11033-022-07845-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Accepted: 08/05/2022] [Indexed: 11/29/2022]
Abstract
Background Carmustine (Cr) is an important chemotherapeutic drug, widely used in the treatment of brain tumors. Herein, the protective role of Codiaeum variegatum leaves ethyl acetate fraction was determined against genotoxicity of Cr. The technique HPLC-qTOF-MS/MS was used to identify the constituents in C. variegatum. Materials 90 male mice were used to evaluate micronuclei (MPCEs) in bone marrow, chromosomal aberration (CAs) in bone marrow and mouse spermatocytes, sperm abnormalities, and gene expression (qRT-PCR). The following groups were included, I: Negative control (ethanol 30%), II: Positive control (i.p injected once with 30 mg/kg Cr), III: Control orally treated with C. variegatum at 500 mg/kg, four days. IV-VI: treated with 100, 300, and 500 mg/kg of the plant (4 days) plus a single dose of Cr. Results In bone marrow, Cr induced significant increase in MPCEs and CAs by 3 and 7-folds respectively over the control. Cr also induced a significant percentage of CAs in spermatocytes in meiosis in the form of univalent (X–Y and autosomal univalent) and also a significant percentage of morphological sperm abnormalities was recorded. A large number of coiled tail abnormalities were detected indicating the effect of Cr in sperm motility. Cr induced an overexpression of p53 gene. C. variegatum mitigated all deleterious genotoxic effects of Cr. Chemical analysis showed that flavones (35.21%) and phenolic acids (17.62%) constitute the main components. Conclusions The results indicated that Cr is genotoxic in both somatic and germ cells. The active components in C. variegatum together participate in the obtained protective role.

Development of a DNA barcode library of plants in the Thai Herbal Pharmacopoeia and Monographs for authentication of herbal products. Sci Rep 2022; 12:9624. [PMID: 35688884 PMCID: PMC9187672 DOI: 10.1038/s41598-022-13287-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Accepted: 05/10/2022] [Indexed: 11/09/2022] Open
Abstract
Traditional herbal medicine has long been practiced as a method of health care in many countries worldwide. The usage of herbal products has been increasing and is expected to continue to do so in the future. However, admixture and adulteration are concerns regarding the quality of herbal medicine, including its safety and efficacy. We aimed to develop a reference DNA barcode library of plants listed in the Thai Herbal Pharmacopoeia (THP) and Monographs of Selected Thai Materia Medica (TMM) (n = 101 plant species) using four core barcode regions, namely, the ITS2, matK, rbcL and trnH-psbA intergenic spacer regions, for authentication of the plant origin of raw materials and herbal products. Checking sequences from samples obtained from local markets and the Thai Food and Drug Administration (Thai FDA) against our digital reference DNA barcode system revealed the authenticity of eighteen out of twenty tested samples as claimed on their labels. Two samples, no. 3 and 13, were not Cyanthillium cinereum (L.) H.Rob. and Pueraria candollei Wall. ex Benth. as claimed, respectively. They were recognized as Emilia sonchifolia (L.) DC. and Butea superba (Roxb.), respectively. Hence, it is important for the Thai FDA or regulatory agencies to immediately initiate strict enforcement for the development of pharmacopoeial standards as well as revisions or modifications of available regulatory guidelines and to implement close monitoring for the quality control of herbal products in terms of authentication before they enter the herbal market. The centralized digital reference DNA barcode database developed here could play a very important role in monitoring or checking the authenticity of medicinal plants.

Ethanolic extracts of Pakistani euphorbiaceous plants induce apoptosis in breast cancer cells through induction of DNA damage and caspase-dependent pathway. Gene 2022; 824:146401. [PMID: 35276236 DOI: 10.1016/j.gene.2022.146401] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 02/20/2022] [Accepted: 03/04/2022] [Indexed: 12/20/2022]
Abstract
BACKGROUND Numerous plants of Euphorbiaceae, thespurgefamily are traditionally used for the treatment of different diseases and recent studies also reported anti-oxidant, anti-inflammatory, and anti-tumor activities of these plants. However, the medicinal potential of several indigenous euphorbiaceous plants of Pakistan is not described yet. Therefore, we intended to evaluate the in vitro anti-breast cancer potential of 10 euphorbiaceous plants of Pakistan. METHODS Cytotoxic screening of ethanolic extracts of selected plants was performed by MTT assay. The qualitative phytochemical analysis was performed to find the major groups of chemicals responsible for cytotoxic activity. To determine the genotoxic effect of plant extracts, microscopic analysis was carried out. Flow cytometry and fluorescent microscopic analysis were done to detect apoptosis. To find out the expression analysis of cell cycle and cell death regulatory genes, quantitative real-time polymerase reaction (qRT-PCR) was performed. RESULTS Among the 10 tested plants, ethanolic extracts of Croton tiglium (CTL) and Euphorbia royleana (ERA) were found to possess the highest anti-proliferative activity against breast cancer cells (MDA-MB-231, MCF-7), with IC50 values 100 and 80 µg/mL respectively. The phytochemical analysis confirmed the presence of phenols, flavonoids, and steroids in both plant extracts, whereas, glycosides and saponins were found only in CTL and ERA, respectively. The cellular aberrations and nuclear morphologies with a distinct DNA laddering pattern substantiated the genotoxic effects. Furthermore, our data showed that CTL and ERA induce cell cycle arrest at the G1/S phase by down-regulating the CDK4 and Cyclin D1 expression followed by caspase-dependent induction of apoptosis in both MCF-7 and MDA-MB-231 cells. However, based on the activation of initiator and executioner caspases, two distinct types of apoptotic pathways are proposed for these plants. The CTL prompted extrinsic while ERA triggered the intrinsic pathways of apoptosis. CONCLUSION Our data demonstrate the strong anti-proliferative and caspase-dependent apoptotic potential of CTL and ERA against breast cancer cells. Further studies are suggested to find clinical implications of these plants in breast cancer therapeutic.
