Thank you for your reply. I have few more doubts.
Instead of mustard oil can I use sesame oil. and can i put this regularly to keep the ears healthy.
I have the problem of ringing in my ears. Some times suddenly the ears get blocked and after some time they unblock again. But if I keep them open to cold weather during nights they get blocked badly. Can you suggest any home remedy for this. I consulted a ENT and he said there is no problem and so no remedy. Please do help me.
