Can Dogs Eat Sage

Sage (Salvia officinalis) is another member of the mint family that is native to the Mediterranean. Today it grows freely in many parts of the world.

Today sage exists in numerous cultivars and varieties. It’s often grown as an ornamental plant or ground cover. Historically, sage is best known as a culinary herb and for use as a medicinal herb.

Traditionally, sage has been used for warding off evil, for snakebites, and to increase female fertility, to name just a few popular beliefs.

Another study that used a sage essential oil found that it was effective in killing the Candida albicans fungus and stopped it from spreading.
