Medicinal Plants used during Antenatal Care by Pregnant Women in Eastern Uganda.

Plants are commonly used during the antenatal stage in pregnancy to manage different ailments in Africa. In Uganda, both medicinal and food plants are used to handle common pregnancy related conditions. An ethnobotanical survey was conducted in Iganga district, eastern Uganda. Seven traditional birth attendants (TBA) and 46 mothers were interviewed. Data was collected using structured questionnaires and household interviews. The TBAs were identified using snowball sampling. A total of 33 plant species, belonging to 23 families were documented. Out of these, the pregnant mothers used 45.5 % as both food and medicine. The most frequently used plant life form was herbs (58.8%). The leaves are the most commonly used plant parts (59%). Most of the plants (58.8%) were semi cultivated and were being domesticated in crop fields and home gardens. Most of the plants were used to manage anaemia and for child development and good health among the pregnant women. The pregnant women and TBAs in Namungalwe sub County have diverse knowledge on medicinal and nutri-medicinal plants in the management of common pregnancy related diseases, which can be used to supplement modern antenatal services, inspite of the ban of the activities of TBA. Further research on the bioavailability of nutrients, efficacy and safety of the medicinal plants used by pregnant women should be done.

Medicinal plants used in malaria treatment by Prometra herbalists in Uganda.

ETHNOPHARMACOLOGICAL RELEVANCE: The aim of the survey was to document medicinal plants used in malaria treatment by Prometra (Promocion de la medicina tradicional amazonica) Traditional Medical Practitioners (TMPs) of Uganda and for search of new antiplasmodial herbal medicines (HMs) for further phytochemical analysis. MATERIALS AND METHODS: In this study, semi structured guided open and close ended questionnaires were used. Focus group discussions were conducted and key informants were chosen within the TMPs who helped in further discussions of how the herbal remedies where collected, prepared and administered. RESULTS: A sample size of 51 respondents was randomly selected among the TMPs with the help of their leader. 86 species distributed over 81 genera and 39 families were reportedly being used as herbal remedies in malaria treatment. The TMPs use symptoms like high temperature, shivering, among others in malaria diagnosis an indication that they understand malaria. They emphasized the use of leaves and bark in treatment because they can regenerate and therefore ensure sustainable use of plants rather than the use of roots which would be destructive. These TMPS treat and also advise their patients on preventive measures against malaria attacks like sleeping under mosquito nets, clearing bushes near homesteads, among others which is an indication that they help in the prevention and mitigation of malaria incidences and prevalence in the areas where they live. The Informant Consensus Factor (FIC) value of 0.8 demonstrated that the TMPs of Prometra-Uganda tend to agree with each other in terms of the plant species they use in malaria treatment an indication of quality control in as far as administration of the herbal remedies. Vernonia amygdalina Delile, Bidens pilosa L., Justicia betonica L. were highly cited as being used in malaria treatment with frequencies of mention of 38, 28 and 25, respectively. CONCLUSION: TMPs of Prometra-Uganda understand and treat malaria using the available plant diversity from their huge forest and the herbal gardens within Buyija forest. The healers are very keen at plant conservation which is a good practice. Species like Justica betonica may be investigated further for antiplasmodial assays to justify its efficacy.

Ethnobotanical study of nutri-medicinal plants used for the management of HIV/AIDS opportunistic ailments among the local communities of western Uganda.

ETHNOPHARMACOLOGICAL RELEVANCE: Herbal remedies are a source of therapeutics for nearly 80% of the population in Uganda. Poor health facilities and limited access to antiretroviral drugs have perpetuated and increased the use of traditional medicine especially in rural areas for the treatment of opportunistic ailments of HIV/AIDS. To document the traditional uses of nutri-medicinal plants in the management of immunocompromised ailments associated with HIV/AIDS. To document the parts and growth forms of plants used, methods of preparation and administration of the herbal remedies. MATERIALS AND METHODS: The study was conducted in Mbarara and Isingiro districts of western Uganda between December 2010 and May 2011. Ethnobotanical information was collected from 64 respondents who were sampled based on recommendations of local elders and administrators. Ethnobotanical data on the use of nutri-medicinal plants for traditional treatment of HIV/AIDS opportunistic ailments were collected by employing semi-structured interviews with selected respondents, house hold visits and field observations as described by (Martin, 1995a). The respondents were mainly traditional medical practitioners who treat patients who are already receiving antiretroviral drugs. Fidelity levels of plant species and informant consensus factor were determined to show the percentage of informants claiming the use of certain plant species for the same major purpose and to analyse people's knowledge of plant use. RESULTS: The study revealed 81 plant species most of which were herbs (49%). Leaves (71%) were the most frequently used parts in remedy preparations which were mainly administered orally (85%). The majority of plants (54%) were harvested from wild populations. Hibiscus sabdariffa L., Plumeria obtusa L., and Abutilon guineense (Shumach.) Baker. F and Exell were the nutri-medicinal plants that scored the highest Fidelity level values. The informant's consensus about usages of plants ranged from 0.75 to 0.80. Plants that are presumed to be effective in treating a certain disease have higher informant consensus factor (ICF) values. Family Asteraceae accounted for 18% of the total species recorded. Thirteen species (16%) of the plants are edible and provide nutritional support. CONCLUSION: The study recorded plant species with potential to treat ailments associated with immunocompromised people living with HIV/AIDS in western Uganda. Such studies can help stimulate confidence in traditional medicine and enhance appreciation of herbal medicine among the people and to appreciate the value of the plant resources and therefore enhance conservation efforts of the plant species. The high consensus means the majority of informants agree on the use of plant species and this reflects the intercultural relevance and the agreement in the use of the nutri-medicinal plants to the people. We recommend the documented plants for further Ethnopharmacological studies.

The antiplasmodial and radical scavenging activities of flavonoids of Erythrina burttii.

The acetone extract of the root bark of Erythrina burttii showed in vitro antiplasmodial activity against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium falciparum with IC(50) values of 0.97 ± 0.2 and 1.73 ± 0.5 µg/ml respectively. The extract also had radical scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical with an EC(50) value of 12.0 µg/ml. The isoflav-3-enes burttinol-A and burttinol-C, and the 2-arylbenzofuran derivative burttinol-D were identified as the most active antiplasmodial (IC(50)<10 µM) and free radical scavenging (EC(50)ca. 10 µM) principles. The acetone extract of E. burttii at 800 mg/kg/day, in a 4-day Plasmodium berghei ANKA suppressive test, showed in vivo antimalarial activity with 52% chemosuppression. In the same in vivo test, marginal activities were also observed for the extracts of the root and stem bark of Erythrina abyssinica and the root bark of Erythrina sacleuxii.

Traditional plants used for medicinal purposes by local communities around the Northern sector of Kibale National Park, Uganda.

ETHNOPHARMACOLOGICAL RELEVANCE: The study was done to establish medicinal plants used in the treatment of various diseases by the people in the Northern sector of Kibale National Park in western Uganda. It was also aimed at establishing the plant parts used and the mode of preparation of remedies. These plants create a basis for phytochemical evaluation which can lead to the discovery of biologically active compounds that can be used as starting materials in the development of new drugs targeting selected diseases such as malaria. MATERIALS AND METHODS: The required information was obtained using open interviews, semi-structured questionnaires, focus group discussions and transect walks. RESULTS: Different medicinal plants (131 species) distributed over 55 families were observed to be used by the local communities around the Northern sector of Kibale National Park. The plants as reported in this paper are used to treat 43 physical illnesses/diseases. The most used parts of the plants are the leaves. Water is the main medium used for the preparation of the remedies which are mostly administered orally. CONCLUSION: The people in the study area have a rich heritage of traditional plants that are used in the health care system to treat diseases. These medicinal plants have contributed significantly to several disease therapies. The most common diseases treated are malaria and cough, which are mostly treated by Vernonia amygdalina Del. and Albizia coriaria Welw. respectively. The main sources of medicinal plants include bush land, home gardens, grasslands, and the forest.

Medicinal plants used to induce labour during childbirth in western Uganda.

Traditional medicine usage in rural Ugandan population for day-to-day health care needs is close to 90%. Women and children form the bulk of the people reliant on herbal medicine. This study was undertaken to document how ethnomedical folklore aids childbirth in rural western Uganda by conducting field surveys, discussions and interviews with the resource users (mothers) and health providers (traditional birth attendants). Health surveys revealed that over 80% of childbirths are conducted at home by using herbal remedies in Bushenyi district. Seventy-five plants have been recorded for usage in inducing labour and some of these plants may be oxytocic. The dilemma lies in the toxicity levels and the unspecified dosages that may threaten the life of the unborn baby and the mother. The high population growth rate, high total fertility rate coupled with high maternal mortality and morbidity in Uganda calls for rethinking in gendered health provision policies and programmes for which herbal medicine integration in health care systems seems viable.

Traditional herbal remedies used in the management of sexual impotence and erectile dysfunction in western Uganda.

BACKGROUND: The utilisation of ethnobotanical indigenous knowledge is vital in male sexual reproductive health care delivery in western Uganda. Reproductive health care is the second most prevalent health care problem in Africa. However, this concept of reproductive health care has been focusing mainly on women disregarding men. Thus, some diseases such as sexual impotence and erectile dysfunction that deserve mention are regarded as petty though important in economic productivity, family stability and sexually transmitted diseases control including HIV/AIDS. OBJECTIVE: This study was carried out mainly to document medicinal plants used in the treatment of sexual impotence and erectile dysfunction disorders in western Uganda. METHODS: The medical ethnobotanical indigenous knowledge were collected by visiting traditional healers and documenting the medicinal plants used and other socio-cultural aspects allied with sexual impotence and erectile dysfunction. The methods used to collect the relevant information regarding the medicinal plants used included informal and formal discussions, field visits and focused semi-structured interviews. RESULTS: Thirty-three medicinal plants used in the management of sexual impotence and erectile dysfunction were documented and Citropsis articulata and Cola acuminata were among the highly utilized medicinal plants. CONCLUSION: From the researchers' point of view, the usage of herbal remedies in managing male sexual disorders is useful because of long cultural history of utilisation and the current renewed interest in natural products to sustain health globally. As a way recognising the values and roles of traditional medical knowledge in health care provision, further research into the efficacy and safety of herbal remedies in male sexual disorders is precious in Uganda and beyond. More so, the establishment of rapport between relevant government department in Ministry of Health, modern health workers through collaborative and networking ventures with traditional healers under close supervision and monitoring of herbal treatments is noble.
