However, scientists from Harvard School of Dental Medicine in Boston think the blue evergreen hydrangea could also work as an anti-ageing drug.
The chemicals in the roots of the plant work by mimicking nutrient deprivation, which prevents blood cells from making the proteins that cause inflammation. Tracy Keller and her colleagues believe this could play a part in preventing inflammatory bowel disease and multiple sclerosis.
