The outcomes have been evaluated in terms of the duration of hospital stay, the time to clinical recovery, safety and non- interference/interaction of Ayurvedic and Further, long term impact of COVID- 19 treatment has been evaluated using quality of life questionnaire after 3 months of discharge. Results: Findings of present study reveals that the Ayurveda add-on formulation of T. cordifolia (Guduchi) and P. longum (Pippali) has reduced the length of hospital stay and improve the recovery time. General feeling of wellbeing and activity levels were better in the 3 month follow-up post discharge in the Ayurveda add-on group.
