Ginseng thought to reduce cancer fatigue

The Chinese herb ginseng could give exhausted cancer patients a physical and emotional boost, research suggests.

A US team at Rochester's Mayo Clinic found daily doses improved energy levels and emotional well-being, in a study of 282 patients.

They say that as studies show over half of cancer patients experience crippling fatigue, adding ginseng to cancer therapies is worth exploring.

Cancer experts urged caution until more work was carried out.
