Background: Combination of extracts from multiple plants are typically used in ethnomedicine to putatively offer more potent chemotherapeutic and chemopreventive effects than that of individual extracts from single plants. Aqueous extracts from two multipurpose plants Strophanthus hispidus (roots) and Aframomum meleguta (seeds) are topically co-administered in the nasal cavities for the ethnomedicinal management of chronic sinusitis. Aim: This study assessed the potential phytochemical synergy between constituent extracts of Strophanthus hispidus (roots) and Aframomum meleguta (seeds) in its anti-inflammation, anti-microbial and anti-oxidant effects. Methods and Materials: Broth dilution assay assessed anti-microbial activities. DPPH radical scavenging assay examined the scope of anti-oxidant activities and inhibition of carrageenan-induced 7-day old chick feet oedema revealed anti-inflammatory activities. Results: Anti-microbial activities of individual plant extracts in broth dilution assay showed comparable potency to that of the co-extract mixture. Similarly, individual extracts showed levels of DPPH radical scavenging activities in anti-oxidant assay that was comparable to those found for the co-extract mixture. In contrast to these two effects, inhibition of carrageenan-induced 7-day old chick feet oedema revealed an anti-inflammatory activity evoked by co-extract mixtures that was greater than the sum of the individual potencies of the two extracts. Conclusion: The potential phytochemical synergy of the two plants extracts in its anti-inflammatory response largely validates ethnomedicinal practice and generally confirms growing literature reports that ascribe the net pharmacological activities of herbal extracts to the combined multi-activities of unique phytochemical entities at multiple target sites.

Ethnomedicine, synonymous with traditional medicine, is a crucial healthcare system practiced by various ethnic groups worldwide, especially among those with limited access to modern Western medicine. This study explores the rich bio-cultural diversity of the North Central Western Ghats in Karnataka, India, which harbors diverse ethnomedicinal practices. The region's tropical forests are home to an extensive array of plant species, with over 600 endemic to southern India and 95 exclusively endemic to Karnataka. The research focuses on documenting and analyzing the traditional knowledge of local communities regarding the use of plants for treating various human diseases. However, this task presents significant challenges and requires collaborative efforts from the government, NGOs, and Herbal Drug Companies. Over the last decade, ethnomedicinal studies have seen a rise, but there is still limited understanding of ethnomedicine's role in the traditional healthcare system in India. The forests of North Central Western Ghats, including Agumbe, Arbail Ghat, Chorla Betta, and others, exhibit a combination of deciduous and evergreen vegetation. These forests hold a variety of medicinal plants, adding to the region's bio-cultural richness. Scientific validation of the locally used ethnomedicinal plants further supports the development of herbal drug formulations with the support of the Ministry of Ayush, enabling the conservation and sustainable utilization of threatened and endangered species. The study emphasizes the importance of preserving traditional healers' knowledge and promoting collaboration for the preservation of ethnomedicinal practices in the region.
