Natural Cold and Flu Remedies

Olive-leaf extract

Take it all winter. Research is mounting in support of this supplement, an extract from the fresh or dried leaves of the olive tree. Oleuropein, the active ingredient in olive-leaf extract, is an antioxidant-rich, virus-fighting powerhouse. The body converts oleuropein to elenolic acid, which studies have shown to be lethal to a number of viruses. Look for Olive Leaf Australia’s Olive Leaf Extract or Olive Leaf Oral Spray.

The Verdict:

Keep an eye on olive-leaf extract, which has shown promise in clinical trials for its antioxidant properties alone.
