'Rosemary is a wonderful herb with a tradition of use spanning millennia. It has innumerable uses in both the kitchen and in herbal medicine.
Did you know that rosemary has been associated with memory enhancement since ancient times? It is true – and it has even been referred to from the latter part of the Elizabethan Era to the Early Romantic period as the herb of remembrance.
In Shakespeare’s Hamlet, Ophelia says, “There’s rosemary, that’s for remembrance.” (Hamlet, iv. 5.) It has also long been used as a symbol for remembrance during weddings, war commemorations and funerals in Europe and Australia.  Mourners in old times would wear it as a buttonhole, burn it as incense or throw it into graves as a symbol of remembrance for the dead.'
