Hi all, Here's the view taken by many holistic health providers on sinus problems/infections. There are a few ways sinus conditions can come about. When the large intestine suffers from inadequate or inefficient elimination, inflamed sinuses/tonsils/adenoids/ lymph nodes result. The large intestine is lined with lymph vessels which can reabsorb waste and recirculate it. When the waste is reintroduced, and the lymph becomes backed up, immune cells flood lymph nodes and the lymph system becomes inflamed. This is when you will see the aforementioned conditions. An overly acidic diet can also affect the sinuses by virtue of making the spleen swollen and imbalanced. So, the solution is in more fiber and more alkalizing foods. Siobhan
