Tangerine peel 'kills cancer'
A compound extracted from tangerine peel can kill certain human cancer cells, research shows.
A team from Leicester School of Pharmacy found Salvestrol Q40 was turned into a toxic compound in cancer cells, destroying them.
Salvestrol Q40 is found at higher concentrations in tangerine peel, than in the flesh of the fruit.
The researchers suggest the modern trend to throw away peel may have contributed to a rise in some cancers.
