Ben,
from what I know there's many applications as to using bay-rum. I wouldn't try using it as a mouthwash or rum drink but as a pre-shave, A/S, body splash, bath water, foot massage lotion, antiseptic and skin toner it works wonders. It is more versatile to use as a product compared to witch hazel or a regular A/S. You gotta love the scent, that's all.
