In Siena we fry it. Can you eat raw sage?!? Yes you can, no worries. Sage is not toxic. In fact I remember the many times my mother extolled the many virtues of salvia officinalis...
Sage, or salvia (from *salvare, to save) acts as an anti-inflammatory, relieves soar throat or tooth ache, calm stress and even improves memory. I bet you won't throw away your salvia now..
