COVID-19 Treatment Clinical Evidence

COVID-19 involves the interplay of 400+ viral and host proteins and factors, providing many therapeutic targets. c19early analyzes 6,000+ studies for 210+ treatments—over 17 million hours of research. Only three high-profit early treatments are approved in the US. In reality, many treatments reduce risk, with 25 low-cost treatments approved across 163 countries.

Naso/oropharyngeal treatment Effective Treatment directly to the primary source of initial infection.
Healthy lifestyles Protective Exercise, sunlight, a healthy diet, and good sleep all reduce risk.
Immune support Effective Vitamins A, C, D, and zinc show reduced risk, as with other viruses.
Thermotherapy Effective Methods for increasing internal body temperature, enhancing immune system function.
Systemic agents Effective Many systemic agents reduce risk, and may be required when infection progresses.
High-profit systemic agents Conditional Effective, but with greater access and cost barriers.
Monoclonal antibodies Limited Utility Effective but rarely used—high cost, variant dependence, IV/SC admin.
Acetaminophen Harmful Increased risk of severe outcomes and mortality.
Remdesivir Harmful Increased mortality with longer followup. Increased kidney and liver injury, cardiac disorders.

Study suggesting benefit with Vitex negundo

Raekiansyah et al., Antiviral Activity of Medicinal Plant Extracts Vitex negundo and Macaranga tanarius Against SARS-CoV-2, Pathogens, doi:10.3390/pathogens14080820

Natural products possess a wide range of biological and biochemical potentials, with plant-derived compounds being significant sources for discovering new drugs. In this study, extracts of Vitex negundo and Macaranga tanarius prepared with different solvents were tested for their antiviral activity against the original SARS-CoV-2 Wuhan strain and its variants using plaque assay, quantitative real time RT-PCR, and immunofluorescence assay (IFA). Our results showed that at their maximum non-toxic concentrations, Vitex-Dichloromethane (DCM) and Macaranga extracts significantly inhibited SARS-CoV-2 Wuhan strain growth in Vero E6 cells, showing a 5-log reduction in plaque assay and confirmed by IFA. Meanwhile, Vitex-Hexane showed moderate activity with a 2-log decrease. The inhibition was shown in a dose-dependent manner. The antiviral efficacy of these extracts was further demonstrated against various SARS-CoV-2 variants including Alpha, Beta, Delta, and Omicron. Both Vitex-DCM and Macaranga showed strong virucidal activity. In addition, Vitex-DCM and Macaranga inhibited the transcriptional activity of purified SARS-CoV-2 RdRp, indicating that RdRp inhibition may contribute to viral suppression as shown at the post-infection stage. Furthermore, combining Vitex-DCM or Macaranga with remdesivir showed a synergistic effect against SARS-CoV-2. These results suggest that Vitex negundo and Macaranga tanarius extracts are promising candidates for anti-SARS-CoV-2 treatments. Their synergy with remdesivir also underscores the potential of drug combinations in fighting SARS-CoV-2 and preventing the emergence of mutant variants.
