Ethnopharmacological application of medicinal plants to cure skin diseases and in folk cosmetics among the tribal communities of North-West Frontier Province, Pakistan

AIM OF THE STUDY The present investigation is an attempt to find out ethnopharmacological application of medicinal plants to cure skin diseases and in folk cosmetics. METHOD We interviewed respondents in 30 remote sites of North-West Frontier Province by a structured interview form in the local language and respondents were queried for the type of herbal cure known to him. RESULTS A total of 66 plant species belonging to 45 families have been recorded. Seventy-five medications for 15 skin diseases and cosmetics were documented. The mode of application was topical as well as oral administration. Water, milk, ghee, oil, eggs, sulphur and butter are used during administration of herbal remedies. About 15 plant species are known for their use to cure multiple skin diseases. Among these Berberis lyceum, Bergenia ciliata, Melia azedarach, Otostegia limbata, Phyla nodiflora, Prunus persica and Zingiber officinale constitutes major plants. The herbal cosmetics products range from face freshness, removal of ugly spots, hair care, and colouring of palm, feet, gums, and teeth. CONCLUSION Most of the reported species are wild and rare; this demands an urgent attention to conserve such vital resources so as to optimize their use in the primary health care system. Since most of the skin diseases are caused by bacteria, viruses and fungi in this context, phytochemical screening for active constituents, biological activities and clinical studies is of global importance.

Optimization for ultrasound extraction of polysaccharides from mulberry fruits with antioxidant and hyperglycemic activity in vitro

Single-factor experiment and Box-Behnken design (BBD) were applied to optimize the ultrasound-assisted extraction of mulberry fruits polysaccharides (MFP). Under optimum conditions: ratio of water to raw material 40.25, extraction temperature 69°C, ultrasonic power 190W and extraction time 75 min, the MFP yield was 3.13% (±0.07%), in accordance to the predicted value of 3.04%. The mulberry fruits polysaccharides fractions was obtained by deproteinization (MFP-1), followed by decolorization and deionization (MFP-2). Carbohydrate content in MFP, MFP-1 and MFP-2 was 58.61% (±1.47%), 69.98% (±0.91%), 81.18% (±1.29%), as well as proteins was estimated 16.50% (±0.86%), 1.57% (±0.63%), 1.02% (±0.18%), respectively. The FT-IR indicated that MFP, MFP-1 and MFP-2 were acidic polysaccharides. The MFP-1 exhibited the strongest antioxidant activity, while MFP-2 showed the strongest hyperglycemic activity in vitro. This may be caused by their different compositions and physical properties in the different mulberry fruit polysaccharides fractions.

Ethnobotanical appraisal and cultural values of medicinally important wild edible vegetables of Lesser Himalayas-Pakistan.

BackgroundThe association among food and health is momentous as consumers now demand healthy, tasty and natural functional foods. Knowledge of such food is mainly transmitted through the contribution of individuals of households. Throughout the world the traditions of using wild edible plants as food and medicine are at risk of disappearing, hence present appraisal was conducted to explore ethnomedicinal and cultural importance of wild edible vegetables used by the populace of Lesser Himalayas-Pakistan.MethodsData was collected through informed consent semi-structured interviews, questionnaires, market survey and focus group conversation with key respondents of the study sites including 45 female, 30 children and 25 males. Cultural significance of each species was calculated based on use report.ResultsA total of 45 wild edible vegetables belonging to 38 genera and 24 families were used for the treatment of various diseases and consumed. Asteraceae and Papilionoideae were found dominating families with (6 spp. each), followed by Amaranthaceae and Polygonaceae. Vegetables were cooked in water (51%) followed by diluted milk (42%) and both in water and diluted milk (7%). Leaves were among highly utilized plant parts (70%) in medicines followed by seeds (10%), roots (6%), latex (4%), bark, bulb, flowers, tubers and rhizomes (2% each). Modes of preparation fall into seven categories like paste (29%), decoction (24%), powder (14%), eaten fresh (12%), extract (10%), cooked vegetable (8%) and juice (4%). Ficus carica was found most cited species with in top ten vegetables followed by Ficus palmata, Bauhinia variegata, Solanum nigrum, Amaranthus viridis, Medicago polymorpha, Chenopodium album, Cichorium intybus, Amaranthus hybridus and Vicia faba.ConclusionsPatterns of wild edible plant usage depend mainly on socio-economic factors compare to climatic conditions or wealth of flora but during past few decades have harshly eroded due to change in the life style of the inhabitants. Use reports verified common cultural heritage and cultural worth of quoted taxa is analogous. Phytochemical analysis, antioxidant activities, pharmacological applications; skill training in farming and biotechnological techniques to improve the yield are important feature prospective regarding of wild edible vegetables.

Ethnobotanical survey of medicinally important wild edible fruits species used by tribal communities of Lesser Himalayas-Pakistan.

ETHNOPHARMACOLOGICAL RELEVANCE Present survey was conducted to explore ethnomedicinal uses and cultural importance of wild edible fruits species by the inhabitants of Lesser Himalayas-Pakistan. MATERIALS AND METHODS Information was obtained through informed consent semi-structured interviews, questionnaires, market survey, focus group conversation, unceremonious dialogue and village walks with key informants. Cultural significance of each species was calculated based on use report by participants at each study site. RESULTS A total of 35 wild edible fruits belonging to 21 genera and 17 families were used for the treatment of various ailments and consumed. Rosaceae was found dominating family with (8 spp.), followed by Moraceae (6 spp.), Rhamnaceae (5 spp.), Palmae and Vitaceae (2 spp. each) and remaining families were represented by one species each. Fruits (48%) were found highly utilized plant parts, followed by leaves (34%), bark, flowers and seeds (4% each), branches, latex and roots (2% each). Water was used as a medium for preparation while milk, ghee, oil, egg and butter are used for application. Modes of preparation were fall into seven categories like fresh parts eaten raw (38%), powder (24%), decoction (20%), extract (12 %), paste (4%), juice and latex (2% each). Based on cultural important index (CI) Morus nigra was found most significant species within top ten fruit plants followed by Morus alba, Olea ferruginea, Berberis lycium, Pyrus pashia, Ficus carica, Ficus palmata, Ziziphus mauritiana, Diospyros lotus and Ziziphus nummularia. CONCLUSIONS Traditional uses of wild edible plant depend mainly on socio-economic factors rather than climatic conditions or wealth of flora. Use reports and citation demonstrated that there is a common cultural heritage regarding the gathered food plants. Further investigation is required for Antioxidant study, essential and toxic components, pharmacological applications; dietary requirements and biotechnological techniques to improve yields.

Botanical ethnoveterinary therapies in three districts of the Lesser Himalayas of Pakistan.

BackgroundEthnoveterinary knowledge is highly significant for persistence of traditional community-based approaches to veterinary care. This is of particular importance in the context of developing and emerging countries, where animal health (that of livestock, especially) is crucial to local economies and food security. The current survey documents the traditional veterinary uses of medicinal plants in the Lesser Himalayas-Pakistan.MethodsData were collected through interviews, focus groups, participant observation, and by administering questionnaires. A total of 105 informants aged between 20–75 years old who were familiar with livestock health issues (i.e. farmers, shepherds, housewives and herbalists) participated in the study.ResultsA total of 89 botanical taxa, belonging to 46 families, were reported to have ethnoveterinary applications. The most quoted families were Poaceae (6 taxa), Fabaceae (6), Asteraceae (5), and Polygonaceae (5). Adhatoda vasica was the most cited species (43%), followed by Trachyspermum ammi (37%), and Zanthoxylum armatum var. armatum (36%). About 126 medications were recorded against more than 50 veterinary conditions grouped into seven categories. The highest cultural index values were recorded for Trachyspermum ammi, Curcuma longa, Melia azedarach, Zanthoxylum armatum var. armatum and Adhatoda vasica. The highest informant consensus factor was found for pathologies related to respiratory and reproductive disorders. Comparison with the local plant-based remedies used in human folk medicine revealed that many of remedies were used in similar ways in local human phytotherapy. Comparison with other field surveys conducted in surrounding areas demonstrated that approximately one-half of the recorded plants uses are novel to the ethnoveterinary literature of the Himalayas.ConclusionThe current survey shows a remarkable resilience of ethnoveterinary botanical knowledge in the study area. Most of the species reported for ethnoveterinary applications are wild and under threat. Thus, not only is it imperative to conserve traditional local knowledge of folk veterinary therapies for bio-cultural conservation motives, but also to assist with in-situ and ex-situ environmental conservation initiatives, which are urgently needed. Future studies that focus on the validation of efficacy of these ethnoveterinary remedies can help to substantiate emic concepts regarding the management of animal health care and for rural development programs.

Health risk assessment and multivariate apportionment of trace metals in wild leafy vegetables from Lesser Himalayas, Pakistan.

Fresh wild leafy vegetables and related soil samples were collected from Lesser Himalayas, Pakistan to evaluate the trace metal levels and related health risk to the consumers. The samples were prepared by acid digestion, followed by quantification of selected trace metals (Fe, Zn, Cu, Mn, Cr, Cd and Pb) on atomic absorption spectrophotometer. Generally, in the vegetables highest concentrations were detected for Fe, followed by Zn, Mn and Pb. Among the vegetables, highest concentrations of Zn, Cu and Cr were found in Solanum nigrum, while Stellaria media showed the elevated levels of Fe and Cd. Nevertheless, maximum concentrations of Mn and Pb were found in Convolvulus arvensis and Amaranthus viridis, respectively. In the case of soil, highest levels were observed for Fe, followed by Mn, Zn, Pb, Cr and Cu. Translocation of trace metals from soil to the vegetables exhibited highest values for Cd, followed by Zn. Multivariate principal component analysis showed significant anthropogenic contributions of the Pb, Cr, Zn, Cd and Fe in the vegetables. Health risk assessment was evaluated in terms of health risk index, target hazard quotient and hazard index which showed that the intake of some trace metals through vegetables was higher than the recommended values, consequently consumption of the vegetables may be associated with non-carcinogenic health risks. Nonetheless, elevated levels of Cr and Pb were also found to be associated with lifetime carcinogenic risk to the consumers.

Phenolic contents and cellular antioxidant activity of Chinese hawthorn “Crataegus pinnatifida”

It is evident from various epidemiological studies that consumption of fruits and vegetables is essential to maintain health and in the disease prevention. Present study was designed to examine phenolic contents and antioxidant properties of three varieties of Crataegus pinnatifida (Chinese hawthorn). Shanlihong variety exhibited elevated levels of total phenolics and flavonoid contents, including free and bond phenolics. Procyanidin B2 was most abundant phenolic compound in all samples, followed by epicatechin, chlorogenic acid, hyperoside, and isoquercitrin. The free ORAC values, and free hydro-PSC values were 398.3-555.8 μmol TE/g DW, and 299.1-370.9 μmol VCE/g DW, respectively. Moreover, the free cellular antioxidant activity (CAA) values were 678-1200 μmol of QE/100 g DW in the no PBS wash protocol, and 345.9-532.9 μmol of QE/100 g DW in the PBS wash protocol. C. pinnatifida fruit could be valuable to promote consumer health.

Medicinal Plant Biodiversity of Lesser Himalayas-Pakistan

The Himalayan region is among the largest mountains systems of the world with uncounted unique medicinal plants resources. The lesser Himalayas ranges are the extension of Greater Himalayas. They have unique ecology, vegetation and diversity of medicinal flora due to tremendous variation in the altitude, climate and associated wildlife. The utilization of medicinal plants in medicine suffers from the fact that although plants are used to treat diseases, scientific evidence is lacking in many cases. Different societies of the world use the plants according to their own beliefs and knowledge and previous experiences. Their knowledge about the use of the plants is usually not known to the other world or science. This book provides a brief introduction of Lesser Himalayas, ethnobotanical aspects, marketing and anthropogenic pressure on medicinal flora. It comprises one hundred medicinal plant species including Pteridophytes, Gymnosperms and Angiosperms (Monocots and Dicots) along with their scientific description and traditional uses.

Ethnomedicinal values, phenolic contents and antioxidant properties of wild culinary vegetables.

ETHNOPHARMACOLOGICAL RELEVANCE Traditional medicines comprise a variety of health practices, approaches, knowledge, and beliefs. Documentation of traditional knowledge, estimation of total phenolics and antioxidant properties of plant species used as wild vegetables and in traditional medicines by the local communities of Lesser Himalayas-Pakistan are targeted. MATERIALS AND METHODS Interviews, questionnaires, and focus group conversation with local informants were carried out to record ethno-medicinal values. Used value, percentage of people who have traditional knowledge, preference ranking and informant consensus factors were also measured. Standard analytical methods were applied to estimate phenolic contents and antioxidant properties in water and acetone extracts. RESULTS A total of 39 plant species used as culinary vegetables and to treat 44 different health disorders are investigated. Significant levels of use value (0.571) and preference ranking (58% PPK, PR-5) are calculated for Ficus palmata, Ficus carica and Solanum nigrum. Elevated levels of total phenolics (144.5 mg GAE/100 g, FW), and flavonoid contents (142.5 mgRtE/100 g, FW) were measured in the water extracts of Origanum vulgare, while Ficus palmata exhibits the highest flavonol contents (142.7 mg RtE/100 g, FW). Maximum DPPH activity is noted in the flowering buds of Bauhinia variegata (85.34%). However, highest values for OH(-) radical scavenging activity (75.12%), Fe(3+) reducing antioxidant power (54.50 µM GAE/100 g, FW), and total antioxidant capacity (180.8 µM AAE/100 g, FW) were measured in the water extracts of Origanum vulgare. CONCLUSION Lesser Himalayas is a rich source of traditional cultural heritage, and plant biodiversity, which are under threat and necessitate urgent documentation. Present study is focused on the plant species used in traditional medicines and culinary vegetables as well. Preliminary determinations of phenoloic contents and antioxidant properties of various plant species were carried out. Present work will introduce new resource of medicinal and food plants, which could be used as functional food. Furthermore, phytochemical profiles, cellular based antioxidant properties, and isolation of active ingredients will be useful for consumers, and in the pharmaceutical and nutraceutical industries of the country.

An ethnobotanical study among Albanians and Aromanians living in the Rraicë and Mokra areas of Eastern Albania

Ethnobotanical research in South-Eastern Europe is crucial for providing the baseline data needed for both implementing community-based management of the local natural resources and (further) developing small-scale markets of local herbal and food products. An ethnobotanical study was carried out among (Muslim) Albanians and (Christian Orthodox) Aromanians living in the Rraicë and Mokra areas of Eastern Albania. The survey was conducted by interviewing 36 local, elderly individuals from five villages regarding the traditional uses of wild food plants, medicinal foods, and home-made medical remedies devoted to both humans and animals. Thirty-six plant taxa were found to comprise the local wild food cuisine as well as the cuisine of medicinal foods and cultivated plants prepared in unusual ways; 59 plant taxa were used in human folk medicine and 20 plant taxa in local ethnoveterinary practices. In total, 221 preparations, the large majority plant-based, were recorded. Among the findings, the uncommon food uses of potato leaves as a vegetable and lacto-fermented potato tubers (until the recent past), the widespread use of Chenopodium and Rumex spp. as wild vegetables, as well as the leaves of Ilex aquifolium as a diuretic remedy, dried wild orchid tubers to treat cough and helminthiasis, and elderberry flowers to treat wounds, deserve further investigation. Approximately half of the plant uses reported by Aromanians were not recorded among Albanians, thus suggesting divergent ethnobotanical pathways, perhaps due to the different religious faiths of the two communities, which have prevented intermarriage over the last few centuries.
