PHILADELPHIA (CBS) - Spice allergy accounts for two percent of food allergies.

The symptoms related to spice allergies can range from sneezing, rash or stomach upset to actually affecting the ability to breathe. It is very difficult to detect spices in foods because the FDA does not regulate spices. This means that labels do not have to even mention the presence of spices.

It gets even worse – spices are not just limited to foods. They can be found in cosmetics, fragrances and even toothpaste.
