Medicinal plants – prophylactic and therapeutic options for gastrointestinal and respiratory diseases in calves and piglets? A systematic review

et al. 2016

BackgroundGastrointestinal and respiratory diseases in calves and piglets lead to significant economic losses in livestock husbandry. A high morbidity has been reported for diarrhea (calves ≤ 35 %; piglets ≤ 50 %) and for respiratory diseases (calves ≤ 80 %; piglets ≤ 40 %). Despite a highly diverse etiology and pathophysiology of these diseases, treatment with antimicrobials is often the first-line therapy. Multi-antimicrobial resistance in pathogens results in international accordance to strengthen the research in novel treatment options. Medicinal plants bear a potential as alternative or additional treatment. Based on the versatile effects of their plant specific multi-component-compositions, medicinal plants can potentially act as ‘multi-target drugs’. Regarding the plurality of medicinal plants, the aim of this systematic review was to identify potential medicinal plant species for prevention and treatment of gastrointestinal and respiratory diseases and for modulation of the immune system and inflammation in calves and piglets.ResultsBased on nine initial sources including standard textbooks and European ethnoveterinary studies, a total of 223 medicinal plant species related to the treatment of gastrointestinal and respiratory diseases was identified. A defined search strategy was established using the PRISMA statement to evaluate 30 medicinal plant species starting from 20’000 peer-reviewed articles published in the last 20 years (1994–2014). This strategy led to 418 references (257 in vitro, 84 in vivo and 77 clinical trials, thereof 48 clinical trials in veterinary medicine) to evaluate effects of medicinal plants and their efficacy in detail. The findings indicate that the most promising candidates for gastrointestinal diseases are Allium sativum L., Mentha x piperita L. and Salvia officinalis L.; for diseases of the respiratory tract Echinacea purpurea (L.) MOENCH, Thymus vulgaris L. and Althea officinalis L. were found most promising, and Echinacea purpurea (L.) MOENCH, Camellia sinensis (L.) KUNTZE, Glycyrrhiza glabra L. and Origanum vulgare L. were identified as best candidates for modulation of the immune system and inflammation.ConclusionsSeveral medicinal plants bear a potential for novel treatment strategies for young livestock. There is a need for further research focused on gastrointestinal and respiratory diseases in calves and piglets, and the findings of this review provide a basis on plant selection for future studies.Electronic supplementary materialThe online version of this article (doi:10.1186/s12917-016-0714-8) contains supplementary material, which is available to authorized users.

The chemical constituents, antibacterial, protection against protein denaturation and membrane stabilization activities of essential oils from flowers, leaves, seeds, bark and roots of M. oleifera were investigated. Of the eight bacterial strains tested, only the growths of four strains were inhibited by the essential oils. The oils from the flowers and seeds were the most active with MIC: 1.25 mg/mL each against P. vulgaris and K. pneumoniae respectively. All tested concentrations of M. oleifera essential oils showed high inhibition of protein denaturation (IC 50 0.2 mg/mL) and high membrane stability (IC 50 : < 0.1 mg/mL) compared to Diclofenac. The essential oils were dominated by eicosane (20.93%, 17.12% and 21.59%) in flowers, leaves and seeds respectively; naphthalene (18.40%) in bark and benzene isothiocyanato methyl (35.83%) in the roots. The results revealed that essential oils from different plant parts of M. oleifera could be explored as potential candidates with alternative or complementary potentials for combating drug resistant bacteria and inflammation.

“…On the other hand, the rhizomes of C. scariosus demonstrate effective inhibition of BSA denaturation. Denaturation of tissue proteins is one of the welldocumented causes of inflammatory and arthritic diseases [ 25 ]. The increments in absorbance of test samples with respect to control indicated stabilization of protein that is inhibition of heat-induced protein (BSA) denaturation by plant extract.…”

Identification of human cyclooxegenase-2 inhibitors from Cyperus scariosus (R.Br) rhizomes

et al. 2014

Cyperus scariosus (R.Br) belongs to the family Cyperaceae and it has a diverse medicinal importance. To identify human cyclooxegenase-2 (COX-2) inhibitors from C. scariosus, the rhizome powder was exhaustively extracted with various solvents based on the increasing polarity. Based on the presence and absence of secondary metabolites, we have selected the methanolic extract to evaluate the anti-oxidant and anti-inflammatory activity. The same extract was further subjected to gas chromatography-mass spectroscopy (GC-MS) analysis to identify the active compounds. Binding affinities of these compounds towards anti-inflammatory protein COX-2 were analyzed using molecular docking interaction studies. Phytochemical analysis showed that methanol extract is positive for all secondary metabolites. The antioxidant activity of the C. scariosus rhizomes methanolic extract (CSRME) is half to that of ascorbic acid at 50 µg/ml. The anti-inflammatory activity of CSRME is higher than that of diclofenac sodium salt at high concentration, which is evident from the dose dependent inhibition of bovine serum albumin denaturation at 40 µg/ml–5 mg/ml. GC-MS analysis showed the presence of nine compounds, among all N-methyl-1-adamantaneacetamide and 1,5,diphenyl-2H-1,2,4- triazine form a hydrogen bond interactions with Ser-530 and Tyr-385 respectively and found similar interactions with crystal structure of diclofenac bound COX-2 protein. Benzene-1, 2-diol, 4-(4-bromo-3 chlorophenyl iminomethyl forms hydrogen bond interactions with Thr-199 and Thr-200 as similar to crystallized COX-2 protein with valdecoxib. Collectively our results suggest that CSRME contains medicinally important anti-inflammatory compounds and this justifies the use of this plant as a folklore medicine for preventing inflammation associated disorders.
