Phytochemical Profiling and Anti-Diarrhoea Activity of a Bi-herbal Aqueous Extract of Psidium guajava and Ocimum gratissimum
Diarrhoeal diseases remain a global health challenge, with rising antimicrobial resistance driving the need for plant-based therapies. This study evaluated the phytochemical composition and anti-diarrhoeal activity of a bi-herbal aqueous extract derived from Psidium guajava and Ocimum gratissimum. The phytochemical analyses were performed using standard methods. The in vitro anti-diarrhoeal activity of the extract was assessed against selected diarrhoeagenic microorganisms (Escherichia coli, Salmonella sp., Shigella dysenteriae, and Aspergillus niger) using the agar well diffusion technique.
