Pti'san. n.s. [ptisanne, Fr. πτισσανή.] A medical drink made of barley decocted with raisins and liquorice.
Thrice happy were those golden days of old,
When dear as Burgundy the ptisans sold;
When patients chose to die with better will,
Than breathe and pay the apothecary's bill. Garth.
In fevers the aliments prescribed by Hippocrates, were ptisans and cream of barley. Arbuthnot.
