Hypoallergenic: Products formulated to contain the fewest possible allergens.

Immune system: The body's defense system that protects us against infections and foreign substances.

Immunotherapy: Immunotherapy is given to gradually increase a person's tolerance to the substances that provoke allergy symptoms (allergens). It's usually recommended for people who suffer from allergies more than three months a year. Immunotherapy can be given as allergy shots and oral tablets or drops.  

Latex: Also known as rubber or natural latex. Latex is a milky fluid derived from the rubber tree. It is used in a wide variety of consumer products, including rubber gloves, tubing, and rubber bands, for example.

Latex allergy: An allergy that develops after some sensitizing contact with latex.

Mast cell: A type of white blood cell that is involved in an allergic reaction. These cells release chemicals such as histamine.

Metered dose inhaler (MDI): Small aerosol canister in a plastic container that releases a burst of medication when pressed down from the top. Many asthma drugs are taken using a MDI.

Mold: Parasitic, microscopic fungi that float in the air like pollen. Mold is a common trigger for allergies and can be found in damp areas, such as basements or bathrooms, as well as in grass, leaf piles, hay, mulch, or under mushrooms.
