This ailment is related with those olfactory cells of the brain that are responsible to regulate the smelling power. The patient is unable to distinguish bad or good smell and odours. Even the bad smelling food items find their way to the stomach due to impaired smelling power. To treat this disease recite, and blow on water before drinking, the following words;
وَاللہُ يَخْتَصُّ بِرَحْمَتِہ
Beside this, take some water in a stainless steel or tin-coated bowl and add some salt into it. Recite the above words and blow on the water. Sniff in this water and allow it to flow out of the nose. The water coming out of the nose should not fall in the bowl but on uncommented earth. It might take some time to cure this but the cure is assured.
