The "mind racing" is itself the main problem you need to fix, and lavender drops (or any kind of harmless physical remedy) won't do that.

What has worked well for me is to deliberately focus my mind on simple, pleasant topics instead of negative, annoying ones. That time at work when I solved a difficult problem. Dream vacation plans. The great view at the end of a long hike.

I'm aware this may not be easy (or possible) for everyone to do.
