Scientists in Japan have discovered that the popular spice cardamom can “train” our cells to be more resistant to viral attacks. A study conducted by Shinshu University and published in the journal Foods shows how components of this spice activate our body's internal defense systems.
How does it work at the cellular level?
Imagine that each cell has its own early warning system. When it senses a threat, it produces special signaling proteins called interferons. These proteins alert neighboring cells to the danger, helping them turn on their defenses and block the virus from multiplying. Japanese researchers have found that cardamom seed extract, and in particular one of its active ingredients (1,8-cineole), causes cells to produce more of these “alarm signals.”
An important step, but not a panacea
It is worth noting that these experiments were conducted in a laboratory setting — on human lung cell cultures, not on living people. This is an important first step that shows that natural compounds have the potential to activate the immune system.
However, it is too early to call cardamom a “natural shield against viruses.” Results from the laboratory can not always be transferred to the complex human body. There is still a lot of work ahead: scientists have to find out whether this effect will be observed in humans, what doses are safe and effective. Nevertheless, the study opens a new direction for the search for affordable means that can support our immunity.
