The botanical heritage of a region is an important resource for local people, which allows them to treat themselves with plants that have already been experienced from generation to generation for their benefits and effectiveness. The aim of this study was to highlight the different uses of lentisk pistachio products in the region of Jijel (Algeria). Systematic surveys have been carried out among different categories of people, by age group; have shown a growing interest in the use of medicinal plants. Two approaches (observation, and interview) were used to support this study, with an ethnobotanical worksheet, to obtain other recipes and more information on lentisk benefits and uses. The survey data processing showed that the lentisk is used for therapeutic purposes, to treat diseases of the skin (29%) and respiratory system (28%). The main and most used part of the plant is its berries. The plant is harvested in a spontaneous state and the picking of berries is done from November (in winter). Oil extraction is the principal preparation (72%). The use of resinous gum was not mentioned. Ten percent of surveys gave culinary recipes for some traditional meals preferred by Jijelians. The current study highlighted the ancestral practices and uses of the lentisk by Jijelians. It is necessary to develop this niche and promote its value chain in order to consolidate the economy of the local population.

The aim of this work is the isolation, identification and evaluation of the antibacterial activity of endophytic fungi from the Algerian medicinal plant Marrubium vulgare L. The isolation of endophytic fungi is carried out by the method of sterilization of surface to eliminate epiphytes then incubation of the fragments treated according to a precise protocol. The identification of the grown isolates allowed us to obtain three fungal strains belonging to three genera: Fusarium, Alternaria and Chaetomium, which are generally of the Deuteromycete phylum. The antibacterial capacity of the fungi was tested against five human pathogenic bacteruim using the agar-fungi disk diffusion method. With an inhibition zone (IZ) spanning from 7.5 to 25 mm, all isolated fungal strains showed antibacterial activity against at least one of the bacteria tested.. However, Fusarium sp has the highest antibacterial activity with an IZ of 19 and 24 mm against S. aureus and B. subtilis, respectively. Finally, our results clearly confirm that the medicinal plant M. vulgare L. presents a reservoir of endophytic fungi, which can be used in various fields, especially pharmaceutical fields.

Medicinal plants are important natural materials used in the treatment of many diseases. In this study, total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of endemic Salvia absconditiflora Greuter & Burdet were determined. Plant samples were collected from Nigde and Erzincan (Turkey) provinces. Ethanol (EtOH) extracts of plant samples were extracted. TAS, TOS and OSI values were determined using Rel Assay Diagnostics kits. As a result of the studies, it has been determined that the samples of the plant collected from Nigde have higher TAS, TOS and OSI values. As a result, it has been determined that S. absconditiflora can be used as a potential antioxidant source due to high TAS values.

Nowadays, whitening of stained teeth has become the most popular topic in aesthetic and cosmetic dentistry. Because of the side effects of materials that were used for bleaching, in this study the effects of some plants which were used in Anatolian folk medicine on the treatment of tooth staining were examined. In this study, upper central incisors which were extracted for periodontal reasons were used. The colour values of numbered teeth were obtained and the teeth were immersed into three different essential oils of medicinal plants (Mentha piperita, Ocimum basilicum, Rosmarinus officinalis, Salvia officinalis) for different time periods (1 day, 1 week, 1 month). At the end of the immersion periods, colour measurements of all samples were made and the colour changes were analysed. Obtained data were statistically analysed by using ANOVA and Duncan test. As a result of the variance analysis, plant species and the duration of immersion was found to be statistically significant. Within the limits of this study, we can indicate that tested medicinal plants has a whitening effect by resulting significant change in tooth colour.

Herbal plants are using for folk medicine since immemorial times. Hippocrates who is the father of medicine, refer to 400 medicinal plants and advised ‘‘let food be your medicine and let medicine be your food’’. Most of plants are using today for medicine. It is still acceptable today that prevention is more important than treatment. Saffron was utilized in folk remedy against scarlet fever, smallpox, colds, asthma, eye and heart diseases, tumours, and cancer.

The study aims to report the ethnobotanical significance of medicinal plants for the treatment of various diseases, phytochemical constituents of those plants, their allelopathic effect, and impact of those plants on the socioeconomic aspect in Gulmi and Okhaldhunga district of Nepal. Altogether 41 species of medicinal plants from two areas were documented, using a semi-structured questionnaire. They have been using those species for the treatment of different ailment ranging from gastrointestinal problems, respiratory tract related problems, cuts and wounds, and dermatological problems. 18 of the potentially valuable medicinal plants were brought for performing secondary metabolites tests in methanol extract. The extracts have shown the presence of alkaloid, carbohydrate, glycosides, flavonoids, tannins, terpenoids, saponins, oil and protein, out of which alkaloid was found to be present in every sample. In contrast, only 5 possessed protein. Out of 18 plant extracts, 11 most valued ones were isolated to carry out allelopathy tests on mungbean seed. Only the control treatment bored germination of the mungbean with full radicle and plumule development. This study also reports the impact of the use of medicinal plants in people’s daily life.

Many different natural materials are used in complementary medicine. Among natural products, herbal materials are used quite a lot. Centaurea rigida Willd. was used as material in this study. The antioxidant and oxidant potential of the plant was determined. The aerial parts of the plant sample were extracted with ethanol in a soxhlet device. Antioxidant and oxidant potentials were measured with Rel Assay kits. As a result of the studies, the total antioxidant value of the plant was determined as 3.522±0.166, the total oxidant value as 15.424±0.281 and the oxidative stress index as 0.440±0.020. It was determined that the plant has antioxidant potential, but its oxidant values are high. As a result, it was determined that C. rigida could be used as a natural antioxidant source.
