Butchering Practices of Veddah; the Indigenous People of Sri Lanka
(In: Proceedings of the International Postgraduate Research Conference 2017 (IPRC – 2017), Faculty of Graduate Studies, University of Kelaniya, Sri Lanka., 2017) Weliange, W.S.; Dandeniya, A.S.; Dewage, D.; Algiriya, A.K.P.P.
The Veddah are an ethnic group of people living in Sri Lanka whose population is limited to around 5000 people according to cense carried out in 2011. They live in several villagers adjacent to their original homeland forests. Seligman brothers have reported in 1911 that Veddah have used the arrow head for butchering. In this study state of art of butchering of the modern day Veddah was studied. The study was done in Rathugala in Batticaloa District where a Veddah community lives in Rathugala village adjacent to their original homeland; Nilgala forest. A monthly field visits were done to Rathugala village during 2010 and 2011. Totally 10 field visits were made and 45 days and nights were spent in the forest with Veddah ascertaining the practices related to the hunting. The interviews were done while in the forest, figures and illustrations of the muscular anatomy and skeletal anatomy of common animals were shown initially to familiarise and to acclimatise Veddah for a long run of study. Observations were made on how a monkey was butchered to produces 13 major meat portions and 8 byproducts. Each major meat portions and byproducts have terminologies in their language. Obtaining primal cuts are exactly similar to the modern method of butchering. The Veddah are still skillful butchers. One specific tool with a sharpen edge and a point is sufficient for successful butchering. During prehistoric period people have used similar methods in butchering. The findings are useful in re-creating prehistoric life style of people. Purpose driven ethnographic studies help gather information, deepen the understanding about the indigenous groups like Veddah, increase the weight of the cultural identity and help understand the lifestyle of prehistoric man.
Ethno-eththo of Sri Lanka, the Vanneale: Ornithology of the Veddah

Interviews were conducted with Veddah; the aboriginal people in Sri Lanka, during fieldwork in 2010 and 2011. Joint observations of birds in the wild, examination of illustrations and bird calls helped generate 25 Veddah names of bird species in two Veddah homelands; Dambana and Nilgala in the Ampaara district, in Sri Lanka. Vernacular names, practical uses, food and other behavioural patterns, and folk beliefs concerning the birds were recorded. Local names dese neei erew on the behaviour; particularly their feeding pattern, place of living and colour patterns in the body. While the birds occupy almost a negligible position in the diet and subsistence activities of the Veddah, birds have important meanings in folk beliefs, spiritual and cultural life. Bird names are also found in several poems and songs. The birds are believed to convey information on unpredictable distribution of animals and their behaviour in the forest. Veddah knowledge of birds is not limited to economically important species, as is often assumed. Veddah are familiar with most discernible species. Ethno-ornithology serves as a platform for studying specific relationships between indigenous culture and endemic birds to help increase local awareness of traditional knowledge. Increasing concerns on sustainable-use and community-based strategies also emphasize the importance of ethno-ornithology, and its implications for biodiversity conservation.
Psidium guajava L. (Common Guava) Peel, Pulp and Leaves as Natural Sources of Antioxidants, Antimicrobials and Photoprotective Agents for Development of Sun Protection Cosmeceuticals
(Asian Journal of Chemistry, 2022) Dewage, D.; Samarakoon, S.; Karunaratne, S.; Rajapakse, N.
Sunscreens with natural ingredients for skin care become a new trend in cosmetology as it protects skin against photo-aging and dermatologic disorders. Therefore, the goal of this study was to evaluate the antioxidant, antimicrobial and photoprotective properties of methanolic extracts of leaves, peel and pulp of Psidium guajava L. to investigate their potentials to be used as sources of cosmeceutical ingredients for sun protection. Chemical constituents of the plant parts were extracted into methanol by maceration. Among the extracts, leaf extract exhibited higher DPPH free radical scavenging activity (IC 50 = 89.56 ± 0.97 μg/mL), than that of peel and pulp extracts. The highest total phenolic content (TPC) and total flavonoid content (TFC) were found to be in the leaf extract. All extracts demonstrated antibacterial activity against the examined potential pathogens in cosmetic products. Among the extracts, leaf extract showed the highest photoprotective property with the sun protection factor (SPF) of 30.38 ± 0.22 at 2 mg/mL indicating its potential to be used in the development of sunscreen formulations.
Significance of Fish in Culture of Veddah; The Indigenous People of Sri Lanka. Short running title; FISH IN VEDDAH CULTURE.
(In: Proceedings of the International Postgraduate Research Conference 2017 (IPRC – 2017), Faculty of Graduate Studies, University of Kelaniya, Sri Lanka., 2017) Weliange, W.S.; Algiriya, A.K.P.P.; Dandeniya, A.S.; Dewage, D.
Archaeological excavations have disclosed the remains of nine species of freshwater fish from rock shelter sediments that confirms the consumption of fish by prehistoric man in Sri Lanka 40,000 years before now. The modern-day descendants of those earliest inhabitants or hunter-gatherers are called as ‗village veddah‘ where they live in the villagers with modern infrastructure facilities such as electricity, and are limited to certain areas of the Island. The present study was carried out to obtain the ichthyologic knowledge possessed by the modern village veddah living in Rathugala and Dambana villages in the Uva Province in Sri Lanka. During an annual circle around each full moon day for 10 consecutive poya days, the research team spent 2-3 days in the Rathugala forest, observing the Village Veddha‘s life style and gathering interpretations from them, from January 2010 to March 2011. Two of the veddahs; the chieftain of Rathugala village and his assistant contributed to the study. Fishing were done in two different seasons; in late June while pools are still running and connected to each other and late July, when pools are isolated. Ichthyo-toxic plant materials were used in fishing in pools while a long knife (18 inches) was used in fish cutting at the margins of wading streams. The fish caught were identified, counted and measured for their total lengths and preparation for cooking was observed. Nine species of plants are known to use for stupefying fish in pools by the Veddhas‘, out of them four species were used in this study. Pools which are not isolated are not suitable for fishing according to the Veddah and therefore fishing is done only in isolated pools. During the study, total of 19 different fish species were identified and 15 vernacular names were recorded. Fishing with ichthyo-toxic plants as performed by the Veddah may not be considered as a detrimental act. Veddah‘s fishing season is aligning together with drying up of the river bed where actual fishing is done at the onset of the splitting of the fish assemblage due to discontinuation of the water flow to the pool. It is disclosed that the fish who withstood the ichthyotoxicity remain till the next rain and breed and proliferate.
