Ecological and Ethnomedicinal Survey of Plants within Homesteads in Abia State, Nigeria Uzoma Darlington Chima*, Adekunle Tajudeen Oladele and Maureen Chiamaka Funmilayo Okorie Department of Forestry and Wildlife Management, University of Port Harcourt 500001, Nigeria

Abstract Ecological and ethnomedicinal survey of plants was conducted in one hundred and twenty homesteads in Mbala, Amuda, Umuaku, and Nneato communities of Nneochi Local Governement Area, Abia State-Nigeria. A total of ninety-one medicinal plant species belonging to seventy-eight genera and forty-eight families, used in the treatment of malaria, yellow fever, fibroid, hepatitis, convulsion, hypertension, diabetes, insomnia, ulcer, rashes, low sperm count, snake bite, among others, were documented. Plant remedies were prepared mostly as infusions or decoctions from different plant parts with mainly water, and palm wine/gin sometimes. The highest number of medicinal plant species (73) was recorded in Mbala, followed by Amuda (71), Umuaku (68) and Nneato (61). Medicinal plant species diversity was highest in Amuda (Simpson 1-D=0.9621; H=3.663), followed by Umuaku (Simpson 1-D=0.9481; H=3.471), Mbala (Simpson 1-D=0.9345; H=3.341), and Nneato (Simpson 1-D=0.9307; H=3.277), respectively. Similarity in medicinal plant species was highest between Umuaku and Nneato (76.71%), followed by Amuda and Umuaku (75.95%), Mbala and Amuda (71.43%), while Mbala and Nneato had the lowest similarity (59.52%). The results of the study showed that traditional medicine is pivotal in the treatment of ailments in the study area, and that the indigenous people of Nneochi have recognized the need to conserve medicinal plants of importance ex situ within homesteads due to threats from unsustainable exploitation and deforestation. Key Words: homesteads, medicinal plants, diversity, similarity, Nneochi

Introduction Medicinal plants are of immense economic importance and are widely consumed globally, particularly by rural populations in developing tropical regions. Most of the world’s poor people live in rural areas. In Nigeria, over 75% of her population falls into this category and are mainly farmers (World Bank 1998). The burgeoning world population and the concomitant increase in anthropogenic activities are rapidly eroding natural ecosystems; resulting to loss of natural habitat for a great number of medicinal herbs and trees (Zahoor et al. 2012), which play important role in the primary health care of rural populations globally.

In different cultures medicinal plants are preserved by various means such as sacred groves, on-farm cultivation, home garden or compound farm, and community forests, to meet their health care needs. Specific plantations of medicinal plants are of rare occurrence in sub- Saharan Africa; however, they are produced in association with other food and cash crops in different agro-ecosystems and forests. Medicinal plants are also produced in compound farms or home gardens alongside fruits and vegetables in the eastern part of Nigeria. Plants such as Milicia excelsa, Bombax sp., Newbouldia laevis, kola accuminata, Garcinia kola, and Chrysophyllum albidum have been reported to be widely preserved in rural villages of Edo State, Nigeria for their me-

Ecological and Ethnomedicinal Survey of Plants

dicinal and cultural values (Azeez et al. 2010). This study focused on inventory, utilization, and ecological diversity of medicinal plants at homesteads in Nneochi Local Government Area of Abia State, Nigeria.

Materials and Methods Data collection Data for the study were collected through oral interview and field inventory. Multistage sampling procedure as described by Oloyo (2001) was used in selecting the homesteads used for the study. In the first stage of sampling, four communities (representing 40%) of the communities in the local government area were randomly selected. In the second stage of sampling, three villages were randomly selected from each of the communities. In the third stage of sampling, ten homesteads were randomly selected from each village for medicinal plant enumeration. This gave a sample size of one hundred and twenty homesteads. In each homestead visited, information was sought on the ailment(s) a particular medicinal plant species is used to treat, the local name, parts of the plant used as medicine, and the form of administration, from the head of the compound. Populations of all medicinal plant species encountered at the homesteads and their habits were recorded. Data from homesteads and villages were pooled for each of the communities.

Data analysis Medicinal plant species richness was computed for each community as the number of medicinal plant species encountered in each community. Alpha (within community) diversity was measured using Simpson’s diversity index (Simpson 1949) and Shannon’s diversity index (Odum 1971).

RESULTS Medicinal plant species of the study area The methods of preparation, mode of administration, disease remedies and plant parts used for enumerated medicinal plant species are presented in Table 1. A total of 91 medicinal plant species belonging to 78 genera and 48 families were enumerated. The ailments treated with the plant species include malaria, yellow fever, fibroid, hepatitis, anaemia, convulsion, snake bite, among others. The common names and populations of the medicinal plant species are shown in Table 2.

Distribution of medicinal plant species among plant families Distribution by families of medicinal plants encountered is shown in (Fig. 1-4) for Mbala, Amuda, Umuaku, and Nneato respectively. In all the enumerated communities, Euphorbiaceae family has the highest occurrence followed by Leguminosae (in Mbala and Amuda), while Asclepiadaceae, Piperaceae, Musaceae, Asteraceae, Rutaceae, Curcubitaceae, Crassulaceae and Arecaceae occurred

Similarity of medicinal plant species among the four communities Medicinal plant species compositional similarity between each pair of the communities is shown in Table 4. Medicinal plant species similarity was highest between Umuaku & Nneato communities, followed by Amuda & Umuaku, and Mbala & Amuda, respectively. The least similarity was observed between Mbala & Nneato.

Discussion The medicinal use of plants in the management and treatment of diseases has been an age long practice worldwide (Sofowara 1982). The results of the study have shown that herbal medicine is pivotal in the treatment of ailments by the indigenous people of Nneochi Local Government Area. Among all methods of treatment in traditional medicine systems, medicinal herbs are the most widely applied (Willow 2011). Medicinal plants recorded during the study and numerous ailments they are used to treat, manage and cure further underscores the indispensable role traditional medicines play in health care system of indigenous people of developing tropical Africa. Plant species like Carica papaya, Mangifera indica, Ceiba pentandra and Psidium guajava were found to be effective in the treatment of malaria. Some of these species have also been reported to be useful in the treatment of malaria in other parts of Nigeria by other workers (e.g. Ajibade et al. 2005; Aiyeloja and Bello 2006). Plants such as Dialium guineense, Ricinus communis, Ocimum gratissimum and Gongronema latifolia are notable among those used in the treatment of stomach ache in children. This is a very common paediatrics ailment in the study area. Eleusine indica decoction is

272

Journal of Forest Science http://jofs.or.kr

used in the treatment of stomach ache while the decocted leaves of Pterocarpus santalinoides are used to treat dysentery. Diabetes and Hypertension (arising from improperly managed high blood pressures) have become very common ailments among the rural poor and the elites in the society especially among the aged. Locally, such diseases are controlled with Piper guineense, Vernonia amygdalina, Bryophyllum pinnatum and Persea americana. The ability of B. pinnatum leaves to lower high blood pressure has been validated with animal studies (Ghasi et al. 2011). Leaves of G. latifolia are used for the treatment of reproductive challenges in men (poor erectile function and low sperm count). Baphia nitida and Chlomolaena odorata are used by the people in the treatment of bleeding resulting from injuries. The seeds of P. americana when processed into powdered form and mixed with pap are also used in the treatment of ulcer. The leaves of C. papaya when decocted are used to regulate menstrual pain among females and also used to remove the venom of snake bite from the affected victim by vomiting. Poultice prepared from the pod of Tetrapluera tetraptera is used in womb cleansing. Plant remedies were prepared mostly as infusions or decoctions from the different plant parts with mainly water, and gin sometimes. The local extractions in most cases do not alter the active chemical compounds in the plant parts, thus preserving almost all their properties (George and Pamplona 2000). In some cases, the medicines were administered with milk and non-alcoholic beverages to make them more palatable. The plant parts used include fruits, leaves, flowers, barks and roots; with the leaves being the most used. This may be attributed to the lesser harm done to the plants when leaves are used. Poffenberger et al. (1992) observed that the use of bark and roots is dangerous to the existence of individual plants as compared to leaves. Trees dominated the populations of medicinal plants in the study area. These were followed by shrubs while the herbs had the lowest populations in the various communities. Analysis on the distribution of medicinal plant species among plant families showed that the family Euphorbiaceae has the highest occurrence followed by Leguminosae (in Mbala and Amuda), while Asclepiadaceae, Piperaceae, Musaceae, Asteraceae, Rutaceae, Curcubitaceae, Crassulaceae and Arecaceae occurred averagely. Medicinal plant species in the families -Gutiferae,

Chima et al.

Apocynaceae, irvingiaceae, Leeaceae, Lauraceae, Annoceae, Costaceae, Tiliaceae, and Sterculiaceae, were represented by few species. The four communities were appreciably similar in terms of their medicinal plants species composition, though similarity was higher for closer communities with respect to distance. Medicinal plant species richness and within-community (alpha) diversity were high in all the communities. Mbala Community had the highest number of species and individuals followed by Amuda, Umuaku and Nneato, respectively. Although, Mbala Community had the highest number of species and individuals, diversity indices for Amuda Community and Umuaku Community were higher than that of Mbala. This indicates a more evenly distribution of the individuals encountered among medicinal plant species in the two communities than in Mbala. The high species richness and alpha diversity of medicinal plants in these communities underscores their importance in traditional healthcare system. WHO (2002) reported that up to 80% of the population in Africa, uses traditional medicine for primary healthcare. It appears that the indigenous people of Nneochi have recognized the need to conserve these medicinal plant species ex situ within their homes probably due to the threat mounted on them in the wild as a result of unsustainable exploitation and habitat destruction. Despite the fact that the people of Nneochi now seem to be cultivating their medicinal plants around their homes, there is also the need for the conservation of forests as they may harbor unknown plants of medicinal importance that can have the cure to some ailments whose cure has not yet been discovered. Okafor (1989) warned that lack of conservation measures will increase the number of endangered species resulting in gradual extinction of numerous plant taxa that are useful as herbal remedies.

Conclusions The study has confirmed the fact that ethnomedicine presents an alternative source of healthcare for most rural dwellers. It has succeeded in documenting over ninety plant species (ranging from trees, shrubs and herbs) having medicinal values and used in traditional medicine by the indigenous people of Nneochi Local Government Area. The

high number of individuals and diversity of these medicinal plant species recorded within homesteads in the various communities underscore their importance in traditional health care system. It was evident from the study that the local people have good knowledge of medicinal plants used by them. Since such knowledge is still mostly taught orally without written records, there is need to conduct a similar survey in as many rural areas as possible. Government should encourage the local people generally to embark on ex situ conservation of plants of medicinal importance around their homes, while also embarking on the conservation of the remaining forests to ensure the in situ conservation of useful and potential medicinal plants which they harbor.
