Dietary therapy and herbal medicine for COVID-19 prevention: A review and perspective
Abstract
A novel coronavirus disease (COVID-19), transmitted from humans to humans, has rapidly become the
pandemic responsible for the current global health crisis. COVID-19 is caused by severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2), which is said to be of zoonotic origin. This review describes the
etiology and signs and symptoms as well as the current allopathic therapy for COVID-19. Additionally,
findings of previous studies on the immunomodulatory effects and antiviral activities of particular foods
and herbs on influenza virus and coronaviruses have been collated, with the aim of promoting the use of
dietary therapy and herbal medicine as COVID-19 preventive therapies, while specific drugs and vaccines
are yet to be discovered or are still under development. The volume of existing reports is irrefutable
evidence that foods and herbs possess a potential antiviral ability against SARS-CoV-2 and can prevent
COVID-19. Foods and herbs could be used as dietary or complementary therapy to prevent infection and
strengthen immunity, as antiviral agents for masks, as disinfectants to curb aerosol transmission, or as
sanitizing agents to disinfect surfaces. However, these hypotheses need to be experimentally verified for
SARS-CoV-2 and COVID-19 patients.
