Allergies:

An unpleasant immune response to a substance which the body has become hypersensitive to.  Around 25% of the UK population at some point has experienced an allergic response at some point in their life.

Allergic substances can include: Food, Insects, Pollen, Cow's milk.

With some allergies, psychosomatic factors may trigger or contribute to allergic responses.  High stress levels can make some allergies much worse.  The immune system can be influenced by the unconscious mind.  Some allergic response may be in response to repressed emotion or past trauma.

Hypnotherapy has been known to be very beneficial with some allergies.
