A bee health product with cancer-fighting properties could become an even bigger export earner than Manuka honey, according to the professor who uncovered its benefits.

Melbourne-based professor Hiroshi Maruta led international research that found Bio 30 bee propolis from New Zealand suppresses neurofibromatosis, a condition that affects the skin and nervous system of one in 3000 people.

Dr Maruta is a visiting professor at Hamburg University Hospital, the University of Maryland in Baltimore, and La Trobe University in Melbourne.
