Stevia is a very sweet herb that is used by many as a zero-calorie sugar substitute. Rebaudioside A (purified from Stevia rebaudiana) is âgenerally recognized as safeâ (GRAS) as a sweetening agent for foods by the US Food and Drug Administration, but no studies have been done on pregnant or breastfeeding women.
A palimpsest (/ËpÃ¦lÉªmpsÉst/) is a manuscript page, either from a scroll or a book, from which the text has been scraped or washed off so that the page can be reused for another document.
Many medieval monks, when short of writing materials, took ancient books to pieces, cleaned off the leaves and used them again. The original script can often be brought out under ultraviolet light. Parchments thus cleaned and freshly inscribed are called palimpsests (Greek palin, âagainâ; psÄstos, âscrapedâ).
