The antiviral effect of fresh ginger

It could just be that fresh ginger - that is, ginger roots, not the dried ginger powder - offers protection against the common but contagious cold virus. This is suggested by an in vitro study published in 2013 in the Journal of Ethnopharmacology.

Study
Jung San Chang, a researcher from Kaohsiung Medical University in Taiwan, experimented with HEP2 and A549 cells. HEP2 and A549 cells are epithelial and lung cells of human origin, respectively.

Chang exposed the cells to human respiratory syncytial virus [HRSV]. The human respiratory syncytial virus is arguably the main cause of the common cold. Chang then looked at whether exposure to fresh or dried ginger extracts could protect cells from the virus.

Results
The higher the concentration of fresh ginger, the lower the percentage of cells that the virus could infect.

Dried ginger, on the other hand, had no effect.

Fresh ginger therefore has an antiviral effect. The figure above may show a bit of the antiviral mechanism of fresh ginger. In high concentrations, ginger stimulates the cells' release of interferon beta release.

Conclusion
"Fresh Zingiber officinale is cheap and could prevent HRSV infection largely by inhibiting viral attachment, internalization, and possibly stimulating IFN-beta secretion", the Taiwanese summarize their findings.

"Fresh Zingiber officinale has been safely used for thousand years world wide to manage various diseases. Our results provide the first evidence to support its possible use to prevent HRSV infection."


The antiviral effect of fresh ginger


The main bioactive substances in fresh ginger are gingerols. When ginger is dried or heated, gingerols turn into shogaols. The anti-viral effect discovered by the Taiwanese may well be the work of gingerols.
