Can I purify my home with "dead" sage?

Hi, let me explain: I practically had a HUGE sage plant but this winter with the sudden frost it dried up almost completely 😭. I wanted to prune it leaving only the main branches, to see if perhaps it can be resumed in spring, but I would hate to throw away all those branches and leaves that are dead/dry, because the plant is very large and there are so many of them. Can I use it to purify the house, or is it better not because it wouldn't bring good vibes?

(I know that sage should be perennial, in fact in many years of that plant this had never happened in winter, I'm so sorry because I was quite fond of it and I really hope that with the heat it will feel good again in some way)
