The earliest record of nasal irrigation is found in the ancient Hindu practice of Ayurveda whose roots are traced to the Vedas. It was customary to perform jala-neti daily, as part of soucha (personal hygiene according to scriptures). The simplest method of nasal irrigation, that is to sniff water from cupped hands and then blow it out, is also a step in the ablution practices (Wudu) of Muslims.
