Exploration of ethnomedicinal plants and their practices in human and livestock healthcare in Haripur District, Khyber Pakhtunkhwa, Pakistan.

BACKGROUND: The utilization of plants and plant resources for various ethnobotanical purposes is a common practice in local towns and villages of developing countries, especially in regard to human and veterinary healthcare. For this reason, it is important to unveil and document ethnomedicinal plants and their traditional/folk usage for human and livestock healthcare from unexplored areas. Here we advance our findings on ethnomedicinal plants from Haripur District, Pakistan, not only for conservation purposes, but also for further pharmacological screenings and applied research. METHODOLOGY: Information of ethnomedicinal plants was obtained using a carefully planned questionnaire and interviews from 80 local people and traditional healers (Hakims) in Haripur District, Pakistan, from 2015 to 2017. Informed consent was obtained from each participant before conducting the interview process. Quantitative ethnobotanical indices, such as relative frequency of citation (RFC), use value (UV) and Jaccard index (JI), were calculated for each recorded species. Correlation analysis between the RFC and UV was tested by Pearson's correlation, SPSS (ver. 16). RESULTS: A total of 80 plant species (33 herbs, 24 trees, 21 shrubs and 2 climbers) belonging to 50 families were being used in the study area to treat livestock and human diseases. Lamiaceae was the most dominant family with 7 species (8.7%), followed by Fabaceae with 6 species (7.5%), and Moraceae with 5 species (6.2%). Local people used different methods of preparation for different plant parts; among them, decoction/tea (22 species) was the popular method, followed by powder/grained (20 species) and paste/poultice (14 species). It was observed that most of the species (~ 12 to 16 species) were utilized to treat human and livestock digestive system-related problems, respectively. The Jaccard index found that plant usage in two studies (District Abbottabad and Sulaiman Range) was more comparable. Local people mainly relied on folk medicines due to their rich accessibility, low cost and higher efficacy against diseases. Unfortunately, this important traditional knowledge is vanishing fast, and many medicinal plants are under severe threat. The most threats associated to species observed in the study area include Dehri, Garmthun, Baghpur, Najafpur and Pharala. CONCLUSION: The study has indicated that local people have higher confidence in the usage of ethnomedicinal plants and are still using them for the treatment of various ailments. Comparative analysis with other studies may strongly reflected the novel use of these plants, which may be due to the deep-rooted and unique socio-cultural setup of the study area. However, awareness campaigns, conservation efforts and pharmacological and applied research are required for further exploration and may be a step in the right direction to unveil prospective pharmaceuticals.

Feedstock particle size and pyrolysis temperature regulate effects of biochar on soil nitrous oxide and carbon dioxide emissions.

Atmospheric greenhouse gas (GHG) concentration increases are a serious problem impacting global climate. Mitigation of agricultural GHG production is crucial as fertilized soils contribute substantially to changes in GHG atmospheric composition. Biochar derived from agricultural or forestry biowaste has been widely used in agriculture and may help mitigate GHG emissions. While different kinds of biochar and their effects on GHG emissions have been studied, feedstock particle size may interact with pyrolysis temperature to impact biochar effects on GHG emissions, but this has not been investigated. Here, feedstock particle size effects on biochar characteristics and soil nitrous oxide (N2O) and carbon dioxide (CO2) emissions were studied using Camellia oleifera fruit shell feedstock with three particle size fractions (0.5-2, 2-5, and 5-10 mm) each pyrolyzed at 300, 450, and 600 °C. Results showed that dissolved organic carbon in biochar increased with particle size when pyrolyzed at 300 °C, but decreased with pyrolysis temperature. The 0.5-2 mm shell-derived biochar was associated with the lowest N2O and CO2 emission rates but the highest net nitrogen mineralization rates compared to 2-5 mm and 5-10 mm shell-derived biochar when pyrolyzed at 300 °C. Overall, shell particle size was more important for soil processes at lower pyrolysis temperatures with less variation among particle sizes at higher pyrolysis temperatures. The results indicated that feedstock particle size may interact with pyrolysis temperature and impact mitigation of soil N2O and CO2 emissions.

Traditional practices of the ethnoveterinary plants in the Kaghan Valley, Western Himalayas-Pakistan / Prácticas tradicionales etnoveterinarias de las plantas en el valle de Kaghan, Himalaya occidental Pakistán

Introduction: Indigenous people in a far-flung mountainous area without basic facilities, mainly rely on medicinal plants to cope with various veterinary health problems. Objective: The present study was carried out to explore the traditional knowledge of ethnoveterinary practices in Kaghan Valley, district Mansehra, Western Himalayas-Pakistan. Method: Ethnoveterinary data were collected between February to October 2014 from nine villages of the Kaghan Valley by involving 80 local people include traditional healers using a semi-structured interview. Results: A sum of 41 plant taxa of ethnoveterinary medicinal plants was documented for treating livestock ailments. Out of which, herbaceous plants were recorded with high percentage (27 species, 65.8 %). Most of the species were used to treat gastrointestinal diseases (12 taxa), followed by health improvement (7 taxa). The widely used part of plants for livestock aliments was the whole plant (9 species) followed by leaves (7 species), and preparation were paste (18 species) followed by powder with 10 species. The highest used values were recorded for Arisaema costatum (0.82), Primula denticulata (0.76), and high relative frequency citations for Berberis lyceum and Dryopteris ramosa with 0.37 each. Among the plant species Skimmia laureola, Thymus linearis and Phytolacca latbenia were among the taxa with cent fidelity level. Conclusion: The flora used in traditional remedies of the valley was found mostly endemic due to excessive utilization. Thus, further chemical investigation, better utilization and conservation of indigenous use of the reported species should be considered for future work.

Soil C-N-P pools and stoichiometry as affected by intensive management of camellia oleifera plantations.

Intensive management of C. oleifera has produced many pure C. oleifera plantations. The transmission of C. oleifera plantation will potentially affect soil C, N, and P pools as well as their stoichiometric characteristics both in top soil layer and vertical soil profile due to the intensive management. To understand changes in vertical pools and stoichiometric characteristics of soil C, N, and P as affected by intensive management of C. oleifera plantations, both mixed and pure C. oleifera plantations were studied. We conducted studies in five locations in Jiangxi, China with both pure and mixed C. oleifera plantations, to compare changes in vertical pools and stoichiometry of C, N, and P. Both C and N pools were significantly different between mixed and pure plantation types of C. oleifera. However, the ratio of C:N, C:P, and N:P was consistently higher in mixed plantations with C:P and N:P altered but C:N ratio did not change with soil depth. The intensive management significantly impact both C and N pools and the stoichiometry of C, N, and P. Intensive management of C. oleifera plantations decreased both C and N pools, especially at the depth of 30-50 cm soil layer. C. oleifera plantation alteration from mixed to pure should be considered in future forest management practice considering the substantial effects on soil element cycling and distribution along vertical soil profile.
