THE value of traditional medicinal plants consumed by the Bidayuh native community in Sarawak each year is notably substantial at about RM32,300 (US$7,600) annually.
This is according to a survey carried by a team of researchers from Universiti Malaysia Sarawak (Unimas).
“This figure is quite significant and reflects the importance of the resources provided by the estimated 1,400 hectares of forested areas in the Jagoi community forest,” says Gabriel Tonga Noweg, a forest researcher who spearheaded the study.
Traditional medicine is an important part of the cultural heritage of Malaysia’s native Bidayuh community in the Jagoi Bau district. To help preserve that heritage and the surrounding forest, Noweg and a colleague set out to determine the economic value of the area’s medicinal plants. They surveyed 1,104 households in the Bidayuh community about the plants’ purposes and frequency of use.
Of the 117 plant species documented, 60 species are medicinal, and nearly 30 species are edible. The three most common medicinal plants are Alpinia galangal, Andrographis paniculata and Uncaria gambier, which are used for fever and skin diseases, hypertension and diabetes, and cuts and pain relief respectively.
Other plant species are used for various purposes ranging from insect repellent to use in religious rituals. Some plants have more than one application, such as treating skin disease as well as reducing flatulence after childbirth.
The team’s analysis revealed that elderly residents used and spent more on medicinal plants than young residents did. They also found that people following native religions consumed traditional remedies more than Bidayuh Christian, indicating that religion is another factor driving their use.
Household income did not influence the decision to buy or use medicinal plants. This is contrary to the view that poorer households prefer plants because they are cheaper than modern medicines.
The team hopes that establishing a baseline for the economic value of medicinal plants will help protect the nearby forest as a community heritage site with a management plan that balances extraction with conservation.
