I'm jealous you guys have that many plants! It will take some work to keep them all healthy and hopefully you have space cause they get somewhat big. I personally buy an oz. of leaves once in awhile just to use with meditation, but you won't trip unless you are extremely extremely sensitive and you hit em a TOn... but like duckfool said a quid is your best bet. You just roll the leaves into a cigar type cylinder and chew them, letting them soak in through your saliva. From what i've read salvia extractions arent really that hard, so you should really read into it because it will be worth your work. Good luck!
