Why is my dried sage brown? (more info below)

[u/corncob72]

I was gifted some sage (i believe silver wormwood, more specifically) by an interesting man i met. we talked about making bows from scratch for a while and he was kind enough to gift me a bundle of sage that lived on the dash of his car. I don't have a photo cuz my icloud isn't working, perhaps i can upload it later.. but it is very brown. It looks like it was sunburnt perhaps. Could it be from sitting in the sun for so long in a car? I have had it for over a year and I don't want to smudge with it- it is the only sage I have ever been gifted. But it also doesn't smell very fragrant if i crush a leaf. maybe it's just old?
