Historical ethnopharmacology of the herbalists from Krummhübel in the Sudety Mountains (seventeenth to nineteenth century), Silesia

2018

Background Krummhübel (after 1945, Karpacz) in the Sudety Mountains (now SW Poland) was called “the village of pharmacists”. At the end of the seventeenth century, there were 57 households, of which about 40 were inhabited by herbalists. Krummhübel herbalists were the first in the Sudety region who applied medicinal mixtures for the treatment of various diseases (using, among others, plants, oils, minerals and even viper venom) in contrast to previous herbalists who only indicated the use of individual plant species for specific diseases. Riesengebirge (in Polish Karkonosze) potions were sold in Austria, the Czech Republic, Poland and Russia, and some of them could even be purchased in Scan…

Ethnobotany of the Aegadian Islands: safeguarding biocultural refugia in the Mediterranean

2021

Abstract Background The Aegadian Islands are located west of Trapani, Sicily. Once the site of bountiful tuna fisheries and fruit orchards (plums, peaches, apricots), grapevines, prickly pears, and grains, the local economy is now based on tourism, and many traditional agricultural and maritime practices have been abandoned. In this study, we aimed to evaluate the state of traditional ecological knowledge (TEK) concerning the use of wild and cultivated plants and fungi for human health, food, maritime, and agricultural purposes on the islands of Levanzo, Favignana, and Marettimo and compare present-day practices with those documented in the past. Methods In-depth semi-structured interviews …

Medieval Monastery Gardens in Iceland and Norway

2021

Gardening was an important part of the daily duties within several of the religious orders in Europe during the Middle Ages. The rule of Saint Benedict specified that the monastery should, if possible, contain a garden within itself, and before and above all things, special care should be taken of the sick, so that they may be served in very deed, as Christ himself. The cultivation of medicinal and utility plants was important to meet the material needs of the monastic institutions, but no physical garden has yet been found and excavated in either Scandinavia or Iceland. Especially the Cistercians were well known for being pioneer gardeners, but also other orders like the Benedictines and A…

Antimicrobial secondary metabolites from the medicinal plant Crinum glaucum A. Chev. (Amaryllidaceae)

2020

Abstract Medicinal plants are known as sources of potential antibacterial compounds including alkaloids. The aim of the present study was to evaluate the antibacterial activities of the extract, fractions, and some secondary metabolites isolated from the leaves of Crinum glaucum A. Chev. (Amaryllidaceae). The antibacterial activities were performed with the ethanol (EtOH) extract, as well as with ethyl acetate (EtOAc) and n-butanol (n-BuOH) fractions. Repeated column chromatography of the fractions led to the isolation of several compounds and their structures were elucidated mainly by means of extensive spectroscopic analysis [(one-dimensional (1D) and two-dimensional (2D) nuclear magnetic…

Anti-Acne Activity of Italian Medicinal Plants Used for Skin Infection

2016

Propionibacterium acnes is implicated in the pathogenesis of acne vulgaris, which impacts >85% of teenagers. Novel therapies are in high demand and an ethnopharmacological approach to discovering new plant sources of anti-acne therapeutics could contribute to filling this void in effective therapies. The aims of our study were two-fold: (1) To determine if species identified in ethnopharmacological field studies as having traditional uses for skin and soft tissue infection (SSTI) exhibit significantly more activity against P. acnes than species with no such reported use; and (2) Chemically characterize active extracts and assess their suitability for future investigation. Extracts of Ita…

Cardioprotection and natural polyphenols: An update of clinical and experimental studies

2018

Myocardial ischemia is the leading cause of death worldwide. Despite better outcomes with early coronary artery reperfusion strategies, morbidity and mortality remain significant. The principal myocardial hallmark of myocardial ischemia is cell death and the associated impairment of cardiac contractility. In this way, the use of extracts from medicinal plants versus synthetic drugs to mitigate post-ischemic damage constitutes an alternative. Despite their proven beneficial effects in cardiovascular disorders, the use of many plants is questioned. Our aim is to update the clinical and experimental studies about the actions of medicinal plants and polyphenol-enriched extracts against ischemia…

Introduction: Novel hybrid combinations containing synthetic or antibiotic drugs with plant-derived phenolic or terpenoid compounds

2017

Abstract Background There is a paradigm shift in chemotherapy from mono-drug therapy towards multidrug combination regimens. Natural products from medicinal plants may play an important role for the design of novel combination therapy protocols. Hypothesis We introduce the novel term “hybrid combination” for the therapeutic combination of chemically defined plant-derived constituents (e.g. phenolic or terpenoid compounds with synthetic or antibiotic drugs to increase pharmacological activity and simultaneously toxic side effects. Study design Several literature databases were screened on the combination of phenolic/terpenoid compounds with synthetic/antibiotic drugs. Results Phenolic compou…

Cytotoxicity of South-African medicinal plants towards sensitive and multidrug-resistant cancer cells

2016

Abstract Ethnopharmacological relevance Traditional medicine plays a major role for primary health care worldwide. Cancer belongs to the leading disease burden in industrialized and developing countries. Successful cancer therapy is hampered by the development of resistance towards established anticancer drugs. Aim In the present study, we investigated the cytotoxicity of 29 extracts from 26 medicinal plants of South-Africa against leukemia cell lines, most of which are used traditionally to treat cancer and related symptoms. Material and methods We have investigated the plant extracts for their cytotoxic activity towards drug-sensitive parental CCRF-CEM leukemia cells and their multidrug-r…

Cytotoxicity of 18 Cameroonian medicinal plants against drug sensitive and multi-factorial drug resistant cancer cells

2018

Abstract Ethnopharmacological relevance Cameroonian medicinal plants are traditionally used to treat many ailments, including cancer and related diseases. Cancer is characterized as a condition with complex signs and symptoms. It has been recommended that ethnopharmacological usages such as immune and skin disorders, inflammatory, infectious, parasitic and viral diseases should be taken into account when selecting plants for anticancer screenings, since these reflect disease states bearing relevance to cancer or cancer-like symptoms. Aim of the study The present study aims at investigating 20 methanol extracts from 15 Cameroonian medicinal plants on a panel of human cancer cell lines, inclu…
