Medicinal plants used in managing diseases of the respiratory system among the Luo community: an appraisal of Kisumu East Sub-County, Kenya

et al. 2020

Background: Poor access to healthcare in rural communities causes many people to seek herbalists who use medicinal plants for the treatment of various disease conditions. Most knowledge of traditional herbal medicine makes use of indigenous remedies which are often undocumented and are at risk of being lost. The preservation of this knowledge may facilitate scientific inquiry into promising new therapeutic molecules. Methods: Semi-structured questionnaires were used to collect the sociodemographic information of 30 herbalists in Kisumu East Sub County. The local names of medicinal plants used in managing illnesses of the respiratory system, their habit, active parts, indications, methods of preparation, routes of administration, scientific identity, and conservation status were also recorded. Other reported traditional uses, pharmacological activities, and toxicological data were identified via a literature search. Results: Most herbalists were female (86.7%), aged between 61 and 70 years (43.3%) with no formal education (56.7%), and had 21-30 years of practice (30%). 44 plant species, belonging to 43 genera and 28 families were identified. Leguminosae and Rutaceae plant families were predominant, leaves were frequently used (33%), and trees were the most common habit (44.4%). Most plants were collected in the wild (79.2%), preparation was mainly by decoction (68.8%), and the administration was mainly orally. The main indication was cough and 79.5% of all documented plant species had previously been reported to have a pharmacological activity relevant to the mitigation of respiratory illnesses. Toxicological data was available for 84.1% of the plant species identified. Conclusions: The predominant use of roots, root barks, and root tubers by herbalists in Kisumu East Sub County threatens to negatively impact the ecological survival of some plant species. The preservation of herbalists' knowledge of medicinal plants in the study area is a pressing concern considering their advanced age and little formal education. There is a need to conserve some of the medicinal plants documented in this study. The medicinal claims made by herbalists also warrant scientific scrutiny.

“…Many researchers worked on aqueous extracts of medicinal plant leaves proving the nematicidal effect against Meloidogyne sp. by stopping the hatching of egg-masses and enhanced the mortality of juveniles with respect to exposure of time under laboratory conditions (Ibrahim et al, 2006;Dawar et al, 2007;Sultana et al, 2011, Latif et al, 2014El-Baha, 2017;Neeraj et al, 2017).…”

The study was carried out to screen the vermicidal activity of various homeopathic medicines at 100, 75 and 50% v/v concentrations of different potencies including mother tincture (Q), 200C and 30C against root-knot nematode Meloidogyne javanica using hatching and mortality test at different time intervals. Notable results were noticed by Kent-20 and Santonine-43 at all tested concentrations by reducing the hatching and complete mortality of M. javanica after 96 hours, while Cina (Q) showed greater reduction in hatching and mortality at 100% concentration followed by minimum hatching of eggs when used at 75 and 50% concentrations but in case of 200 and 30 (C) potency, only 100% concentration showed maximum effect after 72 and 96 hours followed by 75% concentration which had slight effect, whereas 50% concentration found to fail in killing the second stage of juveniles. Other homeopathic drugs used in the experiment showed no significant nematicidal effect against M. incognita. Kent-20 and Santonine-43 at three different concentrations of 50, 100 and 75% was highly effective when used as seed treatment of okra, sunflower, mung bean and mash beans followed by drenching the soil with these concentrations of both homeopathic drugs separately, also resulted in increasing the weight and height of tested crops and reducing the nematode infection on roots plant.

The effects of plant extracts from fresh leaves of five different plants; Acasia arabica, Ziziphusspina christi, Eucalyptus camaldulensis, Lawsonia inermis and Dalbergia sissoo were evaluated against egg-masses hatching and juvenile mortality of root-knot nematode, Meloidogyne javanica under laboratory conditions. Results revealed that, all treatments extracts had significantly (P < 0.05) reduced in the hatching of egg-masses. The maximum reduction occurred in Acasia arabica with the concentration (S) was (97.13%) and the concentration (S/2) was (89.99%), whereas the minimum reduction caused by Ziziphusspina christi with the concentration (S) was (45.49%) and the concentration (S/2) was (24.63%). The same effects of plant extracts against M. javanica juveniles, the most mortality of second stage juveniles was observed in leaf extracts of Acasia arabica, and Dalbergiasissoo with the concentration (S) was (100%) as regarding to and the concentration (S/2) was (100%) in Dalbergia sissoo, while the least in Ziziphusspina christi with the both concentrations S and S/2 (17.0 and 5.33%), respectively.
