Cardamom has antiviral properties

Interferons are proteins that are activated in response to viral infection and trigger the protective mechanisms of cells. In an experiment, Japanese researchers exposed human lung cells (A549) to cardamom extract and simulated viral infection. The results showed that the extract enhances the activity of intracellular receptors that recognize viral DNA and RNA, thereby increasing the production of interferons and protective cytokines.

“Cardamom has long been known as a medicinal plant, but our data show that its extract can also be used as a broad—spectrum antiviral agent,” said Dr. Takeshi Kawahara, head of the study.

The main active ingredient of the spice is 1,8—cineol, also found in eucalyptus, laurel and rosemary. He showed the ability to activate the so—called “nucleic acid sensors” – intracellular mechanisms that first respond to viral invasion.

According to the researchers, interest in the antiviral properties of food ingredients has grown since the COVID-19 pandemic. The Xingxiu team has previously shown that cardamom extract is able to prevent infection with the influenza virus, and the new results only confirmed its potential as a preventive agent.

Experts hope that the discovery will serve as an impetus for the creation of natural supplements and drugs that can support immunity without the side effects of synthetic drugs.
