I bought some chhinkni powder to see if it really works and it turns out it does! In the video I try placing the powder with my fingers in each nostril, then I pushed more in with a q-tip. This triggers multiple loud,, sneezes in a row! I apply more in my other nostril and have loud,powerful, sneezes again. Then I have to blow my nose in a napkin since all of that made my nose itchy and you can hear how congested I got in a short amount of time.
