  • Astragalus. Astragalus is an herb commonly used in Traditional Chinese medicine (TCM). Animal research suggests that its extract may significantly improve immune-related responses (42Trusted Source).
  • Selenium. Selenium is a mineral that’s essential for immune health. Animal research demonstrates that selenium supplements may enhance antiviral defense against influenza strains, including H1N1 (43Trusted Source, 44Trusted Source, 45Trusted Source).
  • Garlic. Garlic has powerful anti-inflammatory and antiviral properties. It has been shown to enhance immune health by stimulating protective white blood cells like NK cells and macrophages. However, human research is limited (46Trusted Source, 47Trusted Source).
  • Andrographis. This herb contains andrographolide, a terpenoid compound found to have antiviral effects against respiratory-disease-causing viruses, including enterovirus D68 and influenza A (48Trusted Source, 49Trusted Source, 50Trusted Source).
  • Licorice. Licorice contains many substances, including glycyrrhizin, that may help protect against viral infections. According to test-tube research, glycyrrhizin exhibits antiviral activity against severe acute respiratory-syndrome-related coronavirus (SARS-CoV) (51Trusted Source).
  • Pelargonium sidoides. Some human research supports the use of this plant’s extract for alleviating symptoms of acute viral respiratory infections, including the common cold and bronchitis. Still, results are mixed, and more research is needed (52Trusted Source).
  • B complex vitamins. B vitamins, including B12 and B6, are important for healthy immune response. Yet, many adults are deficient in them, which may negatively affect immune health (53Trusted Source, 54Trusted Source).
  • Curcumin. Curcumin is the main active compound in turmeric. It has powerful anti-inflammatory properties, and animal studies indicate that it may help improve immune function (55Trusted Source).
  • Echinacea. Echinacea is a genus of plants in the daisy family. Certain species have been shown to improve immune health and may have antiviral effects against several respiratory viruses, including respiratory syncytial virus and rhinoviruses (56Trusted Source).
  • Propolis. Propolis is a resin-like material produced by honeybees for use as a sealant in hives. Though it has impressive immune-enhancing effects and may have antiviral properties as well, more human research is needed (57Trusted Source).
