Medicinal Plants Used for Postpartum Recuperation in an Upland Community in Leon, Iloilo, the Philippines

The utilization of medicinal plants has been a longstanding tradition – providing natural remedies with cultural and therapeutic significance, especially in the context of postpartum care. Thus, this study aims to document the usage of medicinal plants in postpartum recuperation, specifically in herbal steaming and bathing in the upland community of Leon, Iloilo, the Philippines. Semi- structured interviews were conducted with 34 key informants using a snowball sampling method from October–November 2022 and in March 2024, thereby resulting in the documentation of 70 medicinal plant species distributed in 64 genera and 35 families. The Fabaceae family was most represented with seven species, followed by Poaceae with six species, and Lamiaceae with five species. Most of the documented species are non-native (51%) and cosmopolitan, categorized as “least concern” (50%) in the IUCN Red List of Endangered Species. A variety of medicinal plants were documented – including trees (57%), herbs (20%), shrubs (17%), and climbers (6%). Roots (64%) and leaves (24%) were the plant parts used most often, and decoction was the primary form of preparation. These medicinal plants can be found growing within the community's vicinity, with most of them (51%) found in forested areas and the rest (49%) being cultivated. The use value (UV) and family use value (FUV) indices were calculated to evaluate the plant’s importance. Pittosporum pentandrum (Blanco) Merr. had the highest (0.91) UV, followed by Citrus maxima (Burm.) Merr. and Justicia gendarussa Burm.f. (0.88), and Bambusa spinosa Roxb. (0.85). Pittosporaceae (0.91) and Hypericaceae (0.62) had the highest FUVs. The findings of this study will provide a foundation for additional scientific validation of the biological properties of the documented plants, specifically focusing on the most valued species, and raise awareness for the preservation of cultural practices and beliefs regarding postpartum care for women.
