This is a strongly-scented herbal bath milk that produces bubbles and makes the water soft and milky. The scent is predominantly lavender, but there are clearly other herbal notes as well, and it is strong. It comes in a tall glass bottle (which does make it a bit tricky to travel with) and each 200ml bottle is meant to be good for 8 baths. I find the suggested amount to be more than adequate for making a nice bath. And yes, this is the sort of scent that can make you sleepy.
