Sri Lanka harbors over 3000 plant species, and most of these plants have been of immense importance in the traditional systems of medicine in the country. Although there is a rich reserve of indigenous knowledge on medicinal plants, in-depth studies have not been pursued yet to compile the ethnoflora with traditional medicinal applications for the scientific community. Thus, as a continuation of our ethnobotanical inventory work in different regions in the country, the present study was carried out in one of the administrative districts in the North Central area of Sri Lanka known as Polonnaruwa district. The information on the significance of medicinal plants as curative and preventive agents of diseases was collected through semistructured and open-ended interviews from 284 volunteers who were randomly recruited for the study. Ethnobotanical data were analyzed using relative frequency of citation (RFC), family importance value (FIV), and use value (UV). Out of the total participants, 53.7% claimed the use of herbal remedies. A total of 64 medicinal plants belonging to 42 plant families were recorded, out of which L. (RFC = 0.163) was the most cited species. Out of the 42 plant families recorded, the FIV was highest in Zingiberaceae. (Goetgh.) Colebr. was found as the plant with the highest use value. Furthermore, the majority of the nonusers of the herbal remedies were willing to adopt herbal products upon the scientific validation of their therapeutic potential. This study revealed that the indigenous herbal remedies are still popular among the local communities in the study area.
斯里兰卡拥有3000多种植物物种，其中大多数植物在该国的传统医学体系中具有极其重要的地位。尽管在药用植物方面有丰富的本土知识储备，但尚未进行深入研究以编纂具有传统药用应用的民族植物志供科学界使用。因此，作为我们在该国不同地区开展的民族植物学编目工作的延续，本研究在斯里兰卡中北部地区的一个行政区——波隆纳鲁沃区进行。通过半结构化和开放式访谈，从随机招募参与研究的284名志愿者那里收集了关于药用植物作为疾病治疗和预防剂的重要性的信息。使用引用相对频率（RFC）、科重要值（FIV）和使用价值（UV）对民族植物学数据进行了分析。在所有参与者中，53.7%的人声称使用草药疗法。共记录了属于42个植物科的64种药用植物，其中L.（RFC = 0.163）是被引用最多的物种。在记录的42个植物科中，姜科的FIV最高。（Goetgh.）Colebr.被发现是使用价值最高的植物。此外，大多数未使用草药疗法的人在其治疗潜力得到科学验证后愿意采用草药产品。这项研究表明，本土草药疗法在研究区域的当地社区中仍然很受欢迎。
