BackgroundThe residents of remote areas mostly depend on folk knowledge of medicinal plants to cure different ailments. The present study was carried out to document and analyze traditional use regarding the medicinal plants among communities residing in Koh-e-Safaid Range northern Pakistani-Afghan border.MethodsA purposive sampling method was used for the selection of informants, and information regarding the ethnomedicinal use of plants was collected through semi-structured interviews. The collected data was analyzed through quantitative indices viz. relative frequency citation, use value, and family use value. The conservation status of medicinal plants was enumerated with the help of International Union for Conservation of Nature Red List Categories and Criteria (2001). Plant samples were deposited at the Herbarium of Botany Department, University of Peshawar for future reference.ResultsOne hundred eight informants including 72 male and 36 female were interviewed. The informants provided information about 92 plants species used in the treatment of 53 ailments. The informant reported maximum number of species used for the treatment of diabetes (16 species), followed by carminatives (12 species), laxatives (11 species), antiseptics (11 species), for cough (10 species), to treat hepatitis (9 species), for curing diarrhea (7 species), and to cure ulcers (7 species), etc. Decoction (37 species, i.e., 40%) was the common method of recipe preparation. Most familiar medicinal plants were Withania coagulans, Caralluma tuberculata, and Artemisia absinthium with relative frequency (0.96), (0.90), and (0.86), respectively. The relative importance of Withania coagulans was highest (1.63) followed by Artemisia absinthium (1.34), Caralluma tuberculata (1.20), Cassia fistula (1.10), Thymus linearis (1.06), etc. This study allows identification of novel uses of plants. Abies pindrow, Artemisia scoparia, Nannorrhops ritchiana, Salvia reflexa, and Vincetoxicum cardiostephanum have not been reported previously for their medicinal importance. The study also highlights many medicinal plants used to treat chronic metabolic conditions in patients with diabetes.ConclusionsThe folk knowledge of medicinal plants species of Koh-e-Safaid Range was unexplored. We, for the first time, conducted this quantitative study in the area to document medicinal plants uses, to preserve traditional knowledge, and also to motivate the local residents against the vanishing wealth of traditional knowledge of medicinal flora. The vast use of medicinal plants reported shows the significance of traditional herbal preparations among tribal people of the area for their health care. Knowledge about the medicinal use of plants is rapidly disappearing in the area as a new generation is unwilling to take interest in medicinal plant use, and the knowledgeable persons keep their knowledge a secret. Thus, the indigenous use of plants needs conservational strategies and further investigation for better utilization of natural resources.Electronic supplementary materi...

Background: In Kurram district of Pakistan, people use medicinal plants to cure a variety of livestock diseases. This study was conducted with the aims to document the indigenous knowledge of medicinal plants used in veterinary practices in the district.Methods: Ethnoveterinary data were collected through semi-structured interviews with 97 participants that were purposely chosen at random locations and data was quantitatively analyzed using relative frequency of citation (RFC) and use value (UV).Results: In total 81 plants belonging to 43 families were recorded. Asteraceae and Lamiaceae were the most cited botanical families. The plants were used to treat 28 livestock diseases. Among the plant parts, leaves were the most used parts (38 %) followed by the flowers (13 %), seeds (10 %), stem (10 %), fruit (8 %), and roots (7 %). The results showed that (22) plants were used for digestive diseases, (10) for skin problems, (8) against flatulence, (7) as anthelmintic and as refrigerant, and (4) to treat diarrhea and as anti-inflammatory. Conclusions:The study provides an inventory of traditional ethnoveterinary plants from Kurram district of Pakistan for further phytochemical and pharmacological studies in order to explore their active ingredients.

In the current investigation, 16 samples of six species of the genus Polygonatum were collected from different geographical regions in China. Leaf micromorphological traits were studied in detail using scanning electron microscopy. About five-leaf samples were used for each species collected from different geographical regions. A significant variation was found in the foliar epidermal traits such as stomata types and their distribution, epidermal cell shape, anticlinal wall pattern, and various types of trichomes. Polygonal epidermal cells were observed in P. cyrtonema, P. odoratum, P. sibiricum, and P. filipes, rectangular in P. zanlanscianense and P. odoratum and irregular shape in P. filipes and P. zanlanscianense. Straight anticlinal wall pattern was observed in most of the species, but straight to little undulate was observed in P. cyrtonema, P. filipes, and P. zanlanscianense. Similarly, various shape stomata that are, oval, oblong, and elliptical and types that is, paracytic, anomocytic, and actinocytic have been observed. Based on the foliar traits, the P. odoratum and P. sibiricum were found closely related to one another. On the other hand, P. involucratum and P. zanlanscianense shows a strong association. However, P. filipes showed very less similarity with the other five species. Hence this study adds useful information that may be helpful in the further taxonomic classification of the taxa at subspecies level and was found significant in the correct identification and discrimination of the closely related taxa of the genus Polygonatum.

Background: In the southern and tribal districts of Khyber Pakhtunkhwa reside mainly Pashtun ethnic cultures that preferably use local plants to combat various health issues. We conducted surveys in this terrain to make an inventory of plants used traditionally for the treatment of diabetes.Methods: A purposive sampling method was applied in the selection of participants, and semi-structured interviews were used for the collection of data. Voucher specimens of each plant species were preserved in the
