For 45 years my friend drank,washed in and wore clothes cleaned with
water laced with Trichlorethylene (T.C.E.) All her siblings did the
same thing. They are dead from cancer. For the past 5 years she has
suffered from post petic neuralgia. A result of herpes zooster virus
and a severly compromised immune system. How can she now at the age of
65 build up her immune system? What vitamines and herbs and activities
would be helpful? What about the medicines that are used to help  HIV
victims? Because of local lawsuit activity doctors are afraid to get
involved.Any suggestions?

To start searching about any particular disease, here are some sites
which I found very helpful.

Being the patient of colon cancer myself,
I found Honey as the best medicine to boost one's immune system. This
is surely the best gift of God for its creatures, no other medicine
can be better than this. besides it is complete remedy for all
diseases.
Is it possible for u to get Wild honey , if not then try your best to
find Form honey available in the market.
1 table spoon of honey mixed in readily boiled  1 glass of water , mix
it gently ,atleast 1 hour before breakfast.
1 table spoon of honey mixed(as mentioned above) in the evening (1
hour before sunset)
Soon u will sea great difference, but u will have to continue it for a long period.
