I'd never heard of a garlic allergy, so this was new to me so I googled it.
I think the last sentence is significant. I didn't read anything about allergies from smelling garlic, it says to remove it from your diet.

While allergies to garlic are rare, there are people who are intolerant to the spice. Using garlic to combat seasonal allergies may not be the best course of action. Garlic allergy symptoms tend to be mild, so most individuals may not be aware that they are even sensitive. It is best to check with a physician who can test you for a garlic allergy, to ensure that you are not creating more harm to your immune system.

Garlic allergies symptoms include gastrointestinal disruptions, stuffy noses, red, itchy rashes and coughing. Again, garlic allergies tend to be mild, to the point of being attributed to another condition. If an individual does have an allergy to garlic or is remotely sensitive, garlic should be removed from the diet.
