Telegraph | News | The ancient Egyptian recipe for toothpaste: "According to the document, written in the fourth century AD, the ingredients needed for the perfect smile are one drachma of rock salt - a measure equal to one hundredth of an ounce - two drachmas of mint, one drachma of dried iris flower and 20 grains of pepper, all of them crushed and mixed together.
The result is a pungent paste which one Austrian dentist who tried it said made his gums bleed but was a 'big improvement' on some toothpaste formulae used as recently as a century ago."
