Plants have long stood at the intersection of nature and medicine, offering asilent yet powerful chemistry that continues to shape human survival andscientific curiosity. From ancient healing systems to modernpharmacological innovations, their secondary metabolites have emerged askey players in defense, communication and natural product research. Thisbook, “Plants & Secondary Metabolites, Volume 11” is a compilation ofresearch articles based on study of the phytochemicals and theirpharmacology with relevance in a world facing mounting challenges ofmicrobial resistance and ecological imbalance. This volume brings togethereleven carefully curated chapters that explore a rich diversity of plant taxafrom forest fruits and climbers to desert cacti and hemi-parasitic herbs, eachcontributing a unique profile of phytochemicals and bioactive potential. Thestudied species are wild and traditionally valued such as Smilax zeylanica,Carissa spinarum, Diospyros sylvatica, Gouania leptostachya, and Strigadensiflora, to name a few. Included chapters revisit folk therapeutics andtraditional knowledge systems, biochemical and antibacterial profilingwhile addressing the rising wave of antimicrobial resistance and remindingreaders that plant based solutions may offer hope where conventionalmethods falter. This book serves as an invitation to observe more closely, toquestion more deeply, and to respect the intelligence embedded within plantsystems. It is intended for researchers, students, conservationists, andscientists who seek interdisciplinary exploration between biodiversity andbiotechnology, phytochemistry and pharmacology, curiosity andconservation
