Immune enhancers for COVID-19

ABSTRACT

SARS-CoV-2, also known as COVID-19, is a novel coronavirus that began sweeping the globe at the end of 2019, causing mild illness in some patients while leading to devastating shock, immune dysregulation, multiorgan failure, and even death in others. Immune dysregulation may lead to increased susceptibility to severe disease from COVID-19. Immune enhancers could aid in immune regulation and protect against severe COVID-19 infection. Herbal supplements, spices, and lifestyle modifications have been shown to enhance immune responses to a number of pathogens, which may include COVID-19. These immune enhancers could be used adjunctively with vaccines, social distancing, and pharmacologic treatments to prevent life-threatening infection in susceptible patients. © 2023 Elsevier Inc.
