Ethnomedical survey of plants used by the Orang Asli in Kampung Bawong, Perak, West Malaysia

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusions</p> <p>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.</p

Protective effects of Citrullus vulgaris on Irradiated Lymphocyte Sub-membrane

A study was conducted to determine the radioprotective effects of Citrullus vulgaris on the lymphocyte sub-membrane particularly the actin layer. A total of 30 adult male Sprague-Dawley rats were divided into three equal groups of positive control, negative control and treatment. The positive and negative control groups were force fed with 40 ml/kg body weight of normal saline while the treatment group received 40 g/kg body weight of fresh juice of C. vulgaris daily. After a week the positive control and treatment groups were irradiated with 90 rad gamma radiation. Viable lymphocytes were determined using propidium iodine and acridine orange stain and observed under a fluorescent microscope. The percentage of viable lymphocytes of the treatment group(71.0%; p = 0.03) was significantly higher than the positive control group. The results showed that C. vulgaris possessed radioprotective effects because the lymphocyte actin was not damaged. The radioprotection effects could be due to the presence of antioxidants in C. vulgaris
