Believe it or not, salt might be a surprising addition to your allergy prevention arsenal. There are no studies to back this up but plenty of anecdotal evidence is available to suggest that it is very effective.

• Proponents suggest placing a little unprocessed salt onto your tongue and letting it absorb.
• Another option is to place a little on your hand or arm and licking it off. It is certainly worth a try and in small enough doses is unlikely to do you any harm.
