prairie sage seeds, not sure if I’ll be able to

prairie sage seeds, not sure if I’ll be able to separate them from the plant material. I’ve read about various machines to separate seeds using vibration.. so far I used a few techniques from floating to winnowing, to a stack of strainers with every screen size, but flower seeds and small fluffy ones like sage are a challenge. For my own seedbeds I can just grind up the whole plant.
