Yes – they come out of the Yoga / Sanskrit tradition of body cleansing (I believe ‘neti’ is Sanskrit for ‘clean’). The idea is to use water about the same saltiness as blood (1 teaspoon in a pint is about right), pour it up either nostril and have the water flow out of the other nostril. A lot of snot comes out with it. It’s a similar experience to swimming in the sea and getting water up your nose. The next level of cleansing (which I have tried but don’t recommend) is a length of thread, with about the first 10 inches coated in beeswax. This is pushed into the nostril until you can reach into your mouth and pull the thread out. Very yogic and actually easier than it sounds.
A pot used daily it certainly makes the whole nasal system feel great and washes out a lot of crap. I would recommend it. Don’t spend a bunch of money on solutions – simply warm some water to blood temperature and dissolve a teaspoon of salt in a pint. You’ll know if you get the concentration wrong because it’ll sting. The right concentration you won’t even notice.
