Objectives: A recent review on the status of Philippine ethnobotany showed the lack of ethnobotanical studies in the Visayas group of islands. The use of medicinal plants by the Eskaya, an Indigenous ethnic group in the province of Bohol in Visayas, Philippines, has not yet been documented. This study determines the ethnomedicinal knowledge of traditional healers in selected Eskaya communities in Bohol. Methods: Fifteen (15) Eskaya traditional healers were interviewed using a structured questionnaire, and the valuable medicinal plant species were identified through guided field walks. Informal group discussions with the community were also conducted. Moreover, the fidelity level, informant consensus factor (ICF), and use values (UV) were calculated. Results: Our results showed that the majority of the Eskaya healers belong to an older age group (38 – 71 years old). Eighty-five medicinal plants recorded belong to 44 plant families—with Family Lamiaceae having the highest number of species represented. The leaf is the most common plant part used for healing. Blumea balsamifera was an essential plant with a UV of 0.8. Cardiovascular diseases have the highest ICF values of 0.6, and the most common plants used for these diseases include Cymbopogon citratus, Zingiber officinale, and Luffa cylindrica. Conclusion Our study yielded a record of native and non-native medicinal plants used by the Eskaya healers. This initial listing is also their contribution to promoting medicinal plants that are accessible and abundant in their communities.

Background: Despite the mounting studies on the practical use of species of the pantropical family Melastomataceae, especially their medicinal utility, no attempt at compiling the diverse findings has been made to date. Moreover, most reviews of medicinal flora tend to focus more on the biomedical properties of the plants than their equally meaningful evolutionary and ethnobiological aspects. Objectives: This review aimed to describe and synthesize the current knowledge from and trends in medicinal studies of locally relevant members of the Melastomataceae. Specifically, it sought to gather, select, assess, and analyze digitally available field studies about the anti-infective potential of the genera of the Melastomataceae that occur in the Philippines using a combined evolutionary and ethnobiological lens. Methodology: Web-based search was conducted in EBSCO, Google Scholar, PubMed, ScienceDirect, Scopus, and local databases of medicinal ethnobotany for full and original research papers in Filipino or English. Studies were screened and assessed independently based on taxonomic reliability and ethnobiological methodology. Data were analyzed qualitatively using an integrated evolutionary and ethnobiological framework. Results: Thirty-four ethnobiological studies comprising journal articles and theses that surveyed 41 localities and cultural groups from 12 countries were reviewed. Three Philippine native melastome species are used in treating potentially infectious conditions: Dissochaeta divaricata, Melastoma malabathricum, and M. sanguineum. Other genera native to the Philippines with congeneric species used for anti-infective purposes elsewhere are Medinilla, Memecylon, Osbeckia, and Sonerila. Indications with the most cross-regional consensus include cuts, wounds, and skin infections, diarrhea and dysentery, and buccal, respiratory, and urogenital infections. Conclusion This review revealed that Philippine native melastome genera and species are available for infectious disease mitigation and exhibit high use convergence across geographically and culturally divergent communities but remain untapped. Documenting medicinal flora in an area or community based on their evolutionary relationships and ethnomedicinal usage is significant not only in bioprospecting but more importantly, in preserving indigenous knowledge and natural patrimony, especially amid collapsing socioecological systems and emerging diseases.

Traditional medicine is a blend of information gathered over generations from various communities and cultures. Pinus roxburghii Sargent (Pinaceae) commonly known as "chir pine" is widely used in traditional and folkloric systems of medicine. The all parts of the plant are believed to possess medicinal qualities in Ayurvedic and Unani systems of medicine. In these traditional systems of medicine, the plant is used to heal many diseases, including afflictions of the eyes, ears, throat, blood, and skin. The plant parts are rich in various bioactive compounds such as α-pinene, abietic acid, quercetin and xanthone. Resin acids and flavanoid form a major portion of these bioactive compounds. This review presents examples of traditional medicinal uses for P. roxburghii, and subsequently explores the current understanding of the chemical, pharmacological, and biochemical properties of the extracts and the main active constituents found in each tissue of the plant. Clinical trial information is also included where available. Careful evaluation of these data may be helpful for scientists and researchers to discover and evaluate the specific chemical entities responsible for the traditional medicinal uses of P. roxburghii.

Angelica decursiva Fr. et Sav. (Umbelliferae) has traditionally been used to treat different diseases due to its antitussive, analgesic, and antipyretic activities. It is also a remedy for thick phlegm, asthma, and upper respiratory infections. Recently, the leaf of A. decursiva has been consumed as salad without showing any toxicity. This plant is a rich in different types of coumarin derivatives, including dihydroxanthyletin, psoralen, dihydropsoralen, hydroxycoumarin, and dihydropyran. Its crude extracts and pure constituents possess anti-inflammatory, anti-diabetic, anti-Alzheimer disease, anti-hypertension, anti-cancer, antioxidant, anthelmintic, preventing cerebral stroke, and neuroprotective activities. This valuable herb needs to be further studied and developed not only to treat these human diseases, but also to improve human health. This review provides an overview of current knowledge of A. decursiva metabolites and their biological activities to prioritize future studies.

OBJECTIVETo determine the medicinal potential of various plants and their parts extracted with different solvents.

METHODSThe total phenolic content of acetonitrile/water (60%-40%) (ACN/W) and aqueous (W) extract fractions was determined by high-performance liquid chromatography (HPLC), and terpenic compounds were detected by gas chromatography/mass spectrometry (GC/MS). Antioxidant activity of the samples was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and β-carotene bleaching method. Cell viability was investigated by thiazolyl blue tetrazolium bromide [3-(4,5-dimethylthiazol)-2-yl 2,5-diphenyltetrazolium bromide] (MTT) assay. The mechanisms involved in cytotoxic activity were investigated in a murine macrophage cell line (RAW 264.7) and cancer lines.

RESULTSOur findings show that 11 plant species exhibited biological activity. In addition, moderate antibacterial activity was reported against one or more of the tested bacterial strains at two concentrations: 300 μg and 3 mg/disc. Furthermore, our data reveal that among all plants investigated, some extract and hydrophobic fractions were potent scavengers of the DPPH radical (6.78 μg/mL < EC50 < 8.55 μg/mL). Taken together, our results show that Nerium oleander (NOACN/W) and Pituranthos tortuosus (PTACN/W) were highly cytotoxic against RAW 264.7 cells with IC80 values of 0.36, and 1.55 μg/mL, respectively. In contrast, murine macrophage cell lines had low growth and were significantly sensitive to water extracts of Thymus hirtus sp. algeriensis (THW), Lavandula multifida (LMW), and ACN/W extract of Erica multiflora (EMACN/W) at doses > 400, 47.20, and 116.74 μg/mL, respectively. The current work demonstrates that RAW 264.7 cell proliferation was inhibited by samples in a dose-dependent manner.

CONCLUSIONOur findings, validated through free radical scavenging activity, agar diffusion assay, and cytotoxicity of essential oils towards cancer cells, show that ethnomedicinal plants used in this work have a novel application as a tumor suppressor.
