Organic Lash & Brow Serum

I've been using this for about 2 months. I do feel like my eyelashes are a bit longer, but the stuff smells terrible (the castor oil, maybe) and I would not buy it again. Also, there's white sediment at the bottom in a distinct layer that I assume is the ground pearl. If I shake the bottle up, it still does not mix in, so whatever it is is settling out and not really being utilized in the solution.
