When I feel my immune system is low I always have itching at my arms, legs and sometimes all over my body. Can you explain why it is like this?

The body’s inflammatory response is controlled by the immune system by a variety of very complex pathways. If this system is not functioning well, certain cytokines can be expressed abnormally. In your case, it would appear that when you get a bit run down and as your immune system weakens, you have a tendency to histamines and it is this substance that causes you to itch.

Apart from considering the use of Echinacea to strengthen your immune system, you may also benefit from going onto a course of Milk thistle as a ‘detox’. This should help you fix the problem.

I hope that this information is helpful to you.
