ABSTRACT

Introduction:

With the spread of COVID-19 pandemic, healthcare workers and patients look for alternate medicines including Siddha, Ayurveda, Unani and other forms of traditional medicines as we still do not have promising antiviral drugs for COVID-19.

Objective:

To evaluate the in-vitro antiviral activity of Fema Sakthi™ (FS) by eliciting the inhibition of cytopathic effect of Human Coronavirus (HCoV) on African Green Monkey kidney cells (VERO cells). Materials and

Method:

The cytopathic effect (CPE) was performed on Vero cells with Human Coronavirus 229E, a type of Coronavirus associated with respiratory infections. The Median Tissue Culture Infectious Dose (TCID50) was evaluated using Reed-Muench method. 100 TCID50 of HCoV 229E viral suspensions were added to VERO cell culture to induce the cytopathic effect. Uninfected and untreated cells were used as control and five concentrations (62.5, 125, 250, 500 & 1000 µg/mL) of Fema Sakthi™ (FS) were used to study the anti-viral activity. After incubation for 72 hours, the cell viability was observed under the inverted microscope after staining with 0.1% crystal violet.

Results:

Fema Sakthi™ (FS) was found to exhibit inhibition of cytopathic effect at lower concentrations (62.5, 125 and 250 µg/mL) but at higher concentrations (500 and 1000 µg/mL), the formulation itself was cytotoxic to the cells.

Conclusion:

This preliminary study showed that FS has antiviral activity at lower concentrations 62.5, 125 and 250 µg/mL on the VERO cells. However, further specific studies have to be carried out to confirm the anti-viral activity and clinical efficacy using other preclinical and clinical models of Human Coronavirus (HCoV) including COVID-19.
