Abstract Water hyacinth ( Eichhornia crassipes (Mart.) Solms) is a highly invasive aquatic weed native to the Amazonia basin, known for its rapid propagation, adaptability, and utilization in traditional medicine. The study aims to unveil the therapeutic potential of water hyacinth flowers methanolic extract (EC CME) and its four kupchan fractions (EC PESF, EC DCMSF, EC EASF, EC ASF) through diversified chemical‐pharmacological approaches. GC‐MS/MS of EC‐CME uncovered a rich tapestry of 72 phytochemical components. In vitro DPPH scavenging assay and total phenolic content determination assay deciphered promising antioxidant assays with remarkably low IC 50 values of 0.353 and 0.485 μg/mL, respectively for EC‐ESF and EC‐ASF. Besides, different in vivo tests, including tail emersion, acetic acid‐induced writhing, and thiopental‐induced sleeping test of EC‐CME, yielded a remarkable 8.61±0.29 min of tail immersion time compared to the control's 2.05±0.11 min at the highest dose (600 mg/kg). The best % inhibition of writhing was recorded as 47.96 % accrued in 400 mg/kg dose, indicating robust pain‐relieving properties. The onset and duration of sleep are significantly ameliorated for EC‐CME, unveiling its antidepressant potential. Besides, molecular docking studies along with ADME/T analysis also validated the wet lab findings as well as their safety, efficacy, and drug‐likeliness profile. Finally, this work can be an essential hint for utilizing aquatic weeds in drug development research.
