Pungent Smell Coming from Trim in Older Modular Home?

We moved into a modular house that was built in 1986. We had to remove the trim in the kitchen and dining room for a re-model project, and the smell about knocks our socks off. It's not a moldy or mildewy smell, it reminds me faintly of sagebrush when you crush the leaves. I am just curious if anyone knows what this might be, a preservative or a type of wood?, so we can make an educated decision on whether or not to replace it.

Thank you!
