Cassia alata
Linn is a popular herbal remedy in many countries, and its activities have been studied through many studies, starting from in silico, in vitro, and in vivo. This narrative review will focus more on secondary metabolites that are responsible for certain pharmacological activities that have undergone in vivo, in vitro, and in silico testing to determine the underlying mechanism. Twenty pharmacological activities have been identified, with the flavonoid group (emodin, kaempferol, quercetin) as the most prevalent secondary metabolite found in

. There have been numerous studies looking at the role of flavonoids about specific diseases, and flavonoid testing is quite thorough because it covers three different study types. However, there has not been significant progress accomplished in terms of the evaluation of the dosage form so that test results for promising activities like antidiabetic, antifungal, and antiviral can be carried out into further research. Additionally, several disorders lack comprehensive investigation, particularly in silico studies, therefore further study is required to fill any gaps in the knowledge.
