Neti pot

A neti pot (sometimes also called nasal cup or jala neti (जलनेति)) is a small gravy bowl-like pot designed to drown you rinse the nasal cavity. Basically, you pour water (usually a saline solution) down one nostril, and it comes out the other together with the mucus (that is snot for you regular folks) and whatever else happens to be in your nose (such as a tape recorder). The practice has some real benefits — in medical literature, it's usually referred to as nasal irrigation or saline nasal irrigation — but there's also a rather large amount of woo attached to it.

There is decent evidence that it helps reduce the symptoms of allergies, sinusitis, rhinitis, and other nasal unpleasantries (such as the common cold),Harvey R, Hannan SA, Badia L, Scadding G.

Short-term usage of a neti pot is safe, but only if the water has been boiled or adequately filtered (<1µm) before using — several deaths from the Naegleria fowleri amoeba have been reported.Neti pots linked to brain-eating amoeba deaths, NBC News, 16 Dec 2011Neti pot: Can it clear your nose?, James TC Li, Mayo Clinic, Jan. 25, 2018David Rabago, The Use of Saline Nasal Irrigation in Common Upper Respiratory Conditions.

The exact mechanism of efficacy isn't well understood, but it's probably due to the removal of mucus and/or irritants such as dust and pollen, meaning it's one of the few "detox" methods that actually works. For allergic rhinitis, however, it does not address the core reason behind them: blocked nasal passageways are from inflammation and swelling, not from excess mucus. Of course, it may not be possible to use when your nose is badly stuffed up, so even for its medically sound applications, it cannot be a cure-all.
==Not real benefits==
The neti pot's origins are in yoga and Ayurvedic medicine, which probably explains some of the woo that is attached to it.
There is no evidence that the neti pot can also prevent diseases (such as the common cold), as is often claimed. In fact, long-term usage is associated with increased infections of rhinosinusitis (infected sinuses).
Using any liquid other than (distilled and possibly saline) water is also unlikely to provide additional benefits; some people apparently think it's a good idea to use cranberry juice or even urine. There's also a thing called "Super Neti Juice", which contains "elemental silver, de-ionized water, peppermint oil and a surfactant". The peppermint oil may make for a nicer experience much like peppermint in toothpaste does, but you can pick up a bottle of that for a few dollars; no need to shell out $45 for it.
The full list of other health benefits touted by some woo-meisters is long, and includes (but is not limited to) weight loss, better circulation, smoke cessation, ear disorders, depression (and other mental illnesses), better smell, increased intelligence, better eyesight, fewer wrinkles, less grey hair, "cooling and soothing effect on the brain", and "higher states of meditation". All of this has no evidence whatsoever and is simply made up.
