Maybe you need an added approach to the sinus infection problem. For almost 60 years I had a candida problem and could not solve it. Now I have cancer, the result of osteoporosis and a defunct immune system. Therefore, I am trying to beef up the immune system, or at least, establish a "passive" immune system until my own can get up and running again.
Strangely enough, I seem to have accomplished this much.
I am not having any infections at all, in spite of the fact that my oncologist predicted that I would.
And for the first time in 60 years my body is able to overcome a candida invasion. For me, that is really news.
To build up this immune system, I have used many things.
One is oil of oregano and
Colloidal Silver together; I've used that when I had to go out where I might pick up an infection.
As an overall thing, I have taken colostrum (full of anitobidies, etc.), T-cells, B-cells, probiotics, glutamine (to feed the immune system), and literally everything I could learn about. However, it is helping. With cancer and a defunct immune system, I've had no infections even though my husband has had a couple and I'm in the house with him 24 hours a day. So now I am feeding him all the things I've been taking for my immune system.
I am currently trying a product from Rain Forest Nutrition of Austin, Texas. One of its ingredients is cat's claw,supposed to raise the immunity activity by 50%. My next text at the oncologist may tell whether it has done so or not.
