Plant ethnoveterinary uses are evident in various studies around the world, but the ethnoveterinary practices of forage species are not widely reported. Traditional knowledge is rapidly disappearing because of urbanization and commercial activities. The purpose of this study was to document plant species used by the local communities in Malakand Agency, Pakistan for foraging and ethnoveterinary purposes. Twenty different localities in the study area were surveyed for documentation of forage species and related traditional ethnoveterinary knowledge used for livestock. Semistructured questionnaires and field walks were used to conduct 67 interviews with local farmers and herdsmen. A total of 91 forage species from 26 families were documented, as well as their ethnoveterinary applications. Poaceae and Fabaceae were dominant families with 45% and 15% of species respectively. Among the forage species documented, 62 were highly palatable, 26 were moderately palatable and 12 were less palatable. The region's major veterinary diseases are flu, ringworms, inflammations, low milk production, constipation, bloat, mastitis, pneumonia and wounds. The 62 forage species were reported for the first time for various veterinary uses. This study revealed that local communities commonly use a diverse range of forage species in conjunction with indigenous knowledge of ethnoveterinary uses. These forage species have the potential to overcome the recent fodder shortage. Such studies will be beneficial to the commercial production of such forage species.

“…The metal concentrations were found to be affiliated to the distance from mine tailings while vegetation coverage and richness enhanced with increasing distances [11]. The concentrations of Cd (0.06 mg kg −1 ), Cr (2.19 mg kg −1 ), Pb (0.52 mg kg −1 ) and Ni (0.73 mg/kg) were observed in Ajuga bracteosa [10]. Similarly, Amaranthus spinosus was not regarded as a hyperaccumulator since it accumulated metals in proportion below 1,000 mg kg −1 .…”

“…While non-essential heavy metals (Pb, Cd, As and Hg) are highly toxic and no known functions in the plant species [9]. Heavy metal contamination has received considerable focus in recent past because of its persistence, bioaccumulation, and possibly harmful impacts on the environment [10]. Therefore, it is prerequisite to undertake the intervention of isolating and treating heavy metals regions that have been afflicted by heavy metal pollutants and to ameliorate their deleterious consequences on the atmospheric ecosystem [11].…”

This study aims to evaluate the plant species potential to accumulate, concentrate and translocate the heavy metals around the coal mining contaminated site with heavy metals at Harnoi, Abbottabad. The phytosociological surveys involve the systematic study of plant communities within the particular area to show their composition, structure and distribution showed that the contaminated coal mining-associated area was poor in vegetation. Among these, 11 plant species with higher important values (IV) are collected with associated soil and analyzed for the total concentrations of Cadmium (Cd), Copper (Cu), Chromium (Cr), Lead (Pb) and Nickel (Ni) using Atomic Spectrophotometer. The phytoremediation indices (BAF, BCF, TF and TI) were used to evaluate the multi-metals hyperaccumulator and stabilizer plant species. Dodonaea viscosa was evaluated as multi-metals (Cd, Cu and Ni) stabilizer. While the Ajuga bracteosa and Sonchus espera, Sisybrium officinale and Platango ovata stabilize Cd and Cr respectively. The other plant species that can stabilize as single heavy metal are Ajuga bracteosa and Sonchus espera (Cd), Sisybrium officinale and Platango ovata (Cr) and Amaranthus spinosus (Ni) respectively. While the multi-metals accumulator plant species are Bidens pilosa (Cu, Pb and Ni), Chenopodium ambrosioides (Cd, Cu and Ni), Amaranthus spinosus (Cd, Cu and Cr), Ajuga bracteosa (Pb and Ni) and Rumex hastatus (Cd and Ni). However, the single heavy metal accumulator plant species are Sonchus espera (Pb), Conyzea Canadensis (Ni), Platango ovata and Malvastrum coromandelianum (Cu) respectively. These plants could find valuable applications in practical phytoremediation for the remediation near mining tailings at Abbottabad. Moreover, the use of local plants is a promising approach not only for in-situ accumulation and stabilization of heavy metals but also for tolerance and environmental adaptations in the contaminated area.

Protease inhibitors have considerable applications in biomedicine, biotechnology, and therapy. The aim of the study was to evaluate the methanol crude extracts of aerial portions of Portulaca oleracea (P. oleracea) for anti-inflammatory, antioxidant, and protease inhibitor activities, and to evaluate their inhibitory action against various therapeutically significant proteases. A modified colorimetric assay was used to analyze the protease inhibitors on trypsin and other therapeutic enzymes. P. oleracea crude leaf extract exhibited 79.92% antioxidant and 75% anti-inflammatory activity. Analysis of the effects of crude P. oleracea extract on the values of enzyme kinetics (Km, Vmax) was determined by Lineweaver-Burk reciprocal plot. It was found that the extract exhibited a potent inhibitory effect on the Vmax (µmole/min) of the chymotrypsin 26.0, trypsin 18.0, papain 8.33, and elastase 10.0, when compared to control 41.0, 73.0, 11.11, and 20.3, respectively. While no effect on Km except for elastase which was decreased from 0.026 mM for the control to 0.01 mM. It was found that this effect showed a powerful inhibition in a different way. There is a mixed non-competitive inhibition on elastase as well as pure non-competitive inhibition on chymotrypsin, trypsin, and papain. The crude extract contained 53.3%, 55.7%, 14.9%, and 26.9%, respectively, of protease inhibitors for the therapeutic protease enzymes trypsin, papain, chymotrypsin, and elastase. Therefore, trypsin, papain, chymotrypsin, and elastase have been inhibited by the crude extract of P. oleracea. Characterization of the crude extract indicated potent anti-inflammatory and antioxidant effects.
