An extract of cardamom seeds may activate the body’s natural defense mechanisms and strengthen the immune response against viral infections. This conclusion was reached by researchers from Shinshu University in collaboration with the company S&B Foods. The findings were published in the scientific journal Foods.

The researchers found that hot water extract of cardamom, as well as its key active compound — 1,8-cineole — stimulates the production of type I interferons. These signaling molecules play an important role in the innate immune system: they help cells detect viral RNA and DNA and block viral replication at the early stages of infection.

In laboratory experiments using human lung tissue cells, scientists observed that even natural compounds from spices can trigger complex immune reactions similar to those induced by pharmacological agents. At the same time, unlike synthetic drugs, cardamom has a strong safety profile and can be incorporated into foods or dietary supplements.

The authors emphasize that their findings open new possibilities for preventing viral diseases, especially in the context of growing resistance to conventional antiviral medications. However, before cardamom can be recommended as a therapeutic remedy, additional clinical studies are needed.
