Ethnomedical survey of plants used by the Orang Asli in Kampung Bawong, Perak, West Malaysia
Journal of Ethnobiology and Ethnomedicine volume 6, Article number: 5 (2010)
A qualitative ethnomedical survey was carried out among a local Orang Asli tribe to gather information on the use of medicinal plants in the region of Kampung Bawong, Perak of West Malaysia in order to evaluate the potential medicinal uses of local plants used in curing different diseases and illnesses.
Sixteen informants ranging in age from 35 to 65 years were interviewed. A total of 62 species of plants used by Orang Asli are described in this study based on field surveys and direct face to face communication. These plants belonged to 36 families and are used to treat a wide range of discomforts and diseases.
The results of this study showed that majority of the Orang Asli, of Kampung Bawong are still dependent on local plants as their primary source of medication. As the first ethnomedical study in this area, publishing this work is expected to open up more studies to identify and assess the pharmacological and toxicological action of the plants from this region.
Preservation and recording of ethnobotanical and ethnomedical uses of traditional medicinal plants is an indispensable obligation for sustaining the medicinal and cultural resource of mankind. Extensive research on such traditional plants is of prime importance to scientifically validate their ethnomedical claims.
The study of tribal knowledge of plants is an imperative facet of ethnomedical research. People healed themselves with traditional herbal medicines and ancient remedies from time immemorial [1, 2]. Human beings have found remedies within their habitat, and have adopted different strategies depending upon the climatic, phyto-geographic and faunal characteristics, as well as upon the peculiar culture and socio-structural typologies . Most of such information is passed on to the following generations by traditional healers through oral communication and discipleship practice . Moreover, the World Health Organization (WHO) has reported that about 80% of the world population relies on traditional medicine to cure ailments [5, 6]. Plants play a major role in the treatment of diseases and still remain the foremost alternative for a large majority of people [7–9]. This knowledge, if wisely utilized, could draw out promising herbal leads .
Perak, (Fig. 1) (5.02 N latitude and 101.08 E longitude), in Malaysia is one such area where traditional healing systems are still in practice among the local natives, especially the 'Orang Asli' tribes. Till date, no literature is available regarding the ethnomedical knowledge of this area, though there are ethnomedical reports on few other regions in Malaysia [11–13]. The 'Orang Asli', which means 'first people', are considered to be the original natives of peninsular Malaysia. There are about 150, 000 Orang Asli people of which 60% still live in the rain forests. There are 19 sub-groups among them, like Semai, Temiar, Lanoh and Jah Hut to name a few . Many of the Orang Asli practitioners use local plant parts and plant juices to cure ailments and this practice is still in use . Yet, little attention has been given to their traditional expertise to incorporate their knowledge in modern medicine. This study is an attempt to identify and document the use of traditional medicine among the local Orang Asli along the Kampung Bawong region in Perak.
Regular field trips were made to the selected tribal localities in different seasons of the year 2008, conducted in rural area located in Kampung Bawong. The authors worked with a specific tribe of Orang asli called the 'semang' who fall under the group 'negrito' (Fig. 2, 3). Sixteen informants were involved in the interviews. All informants were in the age group of 35 to 65 years. All informants were male. 3 of them were practicing herbalists, and the rest 13 were individuals who gained knowledge on medicinal uses of plants from their parents and relatives who were historically using the plants with promising results. Interviews were conducted in a local dialect of Malay language. Interviewing individual informant was of fundamental importance to assure the reliability of the gathered information. Individual interviews were conducted with 7 informants (3 herbalists and 4 individual informants) and one group discussion involving the remaining 9 informants was also conducted. The interviews were built on trust with a common aspiration to improve the health situation in the country and to conserve and increase the knowledge on medicinal plants. The information was collected in the local dialect of Malay language. Special concern was taken in collecting information to steer clear of any unoriginal information by sources such as books and magazines were rejected. Some informants were repeatedly merited during field trips to confirm the information provided by them previously. Interpretation and translation of the information received into technical or medicinal terms was cautiously avoided during the interviews so as to obtain a genuine picture of customs and uses. All the plants were identified by Dr. Encik Sani, Botanist, Department of Botany, University Kebangsan Malaysia, Selangor, Malaysia. Voucher herbarium specimens were prepared and deposited in the herbarium of Department of Pharmacognosy, Masterskill University College of Health Sciences, Selangor, Malaysia.
Results and Discussion
The present ethnomedical field survey indicated that there are 62 medicinal plant species belonging to a total of 36 families which are used in Kampung Bawong (Table 1). Most of these species grow in the wild naturally and their medicinal properties are crucial in traditional medicine of the Orang Asli. Majority of the species reported in this paper are widely known throughout peninsular Malaysia and are employed for a large number of medical conditions.
The plants were often used by most of the informants more or less for the same purpose, and with only slight variations in recipes. The plants are usually collected from wild. All species were easily recognized by the informants with their respective local Malay dialect names. Some of the plants commonly used belong to the family Euphorbiaceae, Acanthaceae, Leguminosae, Zingiberaceae and Malvaceae. Most of these plants were used to relieve pain and to cure wound. Certain plants have specific use such as Strobilanthes crispus Blume., which is used to enhance the immune system and Eurycoma longifolia Jack., roots used as aphrodisiac. Results of this survey indicate that these plants were in use for a long time by the ethnic group.
This current ethnomedical field survey carried out among the Orang Asli living in the Kampung Bawong region of Perak, Malaysia reveals that many medicinal plants are still broadly used by the population in the area where the study was conducted for treating various diseases and ailments. It is believed that there are more than 100 species of traditional herbal medicines found in this region. Since many plant species are indicated as potential resource for treating various diseases, this should encourage further research in ethnomedicine. The informants' consensus in the treatment of the main reported diseases is quite high, giving more validity to the plants as a traditional remedy.
The current data will expand the genetic resources obtainable in the area of research and signify a potential source of natural products for treating various diseases. The preservation of these plant species is the gateway toward developing efficacious remedies for treating diseases. Due to lack of knowledge and interest among the younger generations, some of the traditional medical information was buried together with the previous generations. This implies that the local government and village authorities need to act fast to conserve the ethnomedical knowledge of Orang Asli in the village Kampung Bawong, and the medicinal plants require preservation in addition to the ethnobotanical and ethnomedical knowledge recording. The preservation of these herbs along with the traditional knowledge of how to use them is an indispensable obligation for sustaining traditional medicine as a medicinal and cultural resource. Thus a future extensive research of these plants in this locality is recommended to identify and assess their ethnomedical claim.
