Respected hakeem sahib, Assalam-o-alaikum!I have a few tested prescriptions that I would want to present to the readers. It is a strange prescription. If you are somewhere outside and if you have to go to a toilet and there is none nearby. Apply your spit on the naval with your finger. Your need is going to subside for some time. If you want to stop sneeze, join your upper lip with your nose, sneezing will stop. The readers shall definitely benefit from these tips (Saima)
