An analytical study of Kalmegh (<i>Andrographis paniculata</i>) and Kiratikta (<i>Swertia chirayita</i>): an economic substitution for metro cities in global pandemic with Healthcare 4.0

Ayurveda has always been a treasure of knowledge. During the COVID-19 pandemic when humans were forced to suffer and no cure seemed to exist to end suffering, the Ayurvedic medicine system once again proved its viability and brought our sufferings to the end. In this manuscript the core idea is to substantiate that the Andrographis paniculata, another indigenous herb, can be a well founded substitute for Swertia chirayita. In this work, authors have made a comparative study between both drugs. For this, a systematic review of literature and a pharmacogonostical study was done. On investigation, both drugs are almost similar in qualitative phytochemical analysis, and qualities as par Ayurvedic pharmacology. It was also observed that most of the therapeutic actions of both drugs are similar. Graphical representation of the different parameters gives more insight to the readers. Use of pictures has also been done to heighten the interest of readers.
