This was told by my ayurvedic doctor. If you have any swelling or injury in your body, just do the following:

1) Warm mustard oil with crushed pieces of garlic. Set the garlic completely dissolve in the oil.

2) Cool the oil and then apply on injured area. The oil smells horrible but it is very good and medicinal.

In Mumbai, there is horrible traffic and dust pollution. I am allergic to dust and used to catch cold every second day. My doctor suggested me to apply little till oil in the insides of my nose (twice a day) before sleeping and before leaving for office in the morning.

Not much oil, just a slight grease. Initially, you will feel like you have a runny nose because of the oil, but later on, you will get used to it and TRUST me.

I didn’t get a allergy cold after that.
