In chinese medicine allergies and depression - depending which kind of both- stem from the same problem / imbalance.

They are both sympotoms to the problem and often treated together.

In west terms - when the body is low - due to stressors such as allergy or depression - it is more likely to be affected by other pressors... Imune system is weak and coping is low. Also hormon levels change that can cause allergic reaction to things and or drpression.

By definition depression supresses. So it would supress body responses and increase liklihood of allergy.

In chinese med allergy very often is caused due to blockage in channels and unresolved emotional states. There is an instictive interlink.

I think to separate body and soul and spirit is a mistake. We would be a lot happier when getting the connection. On all levels :-)
