Sinuses may be just holes in our skull but they are crucial for our health. They reduce weight of the skull; help with speaking and temperature regulation. Obvious evidence of their importance is when you are sick, and they clog, your voice changes and your head fells like it will explode. To avoid problems with sinuses you should drink Sanda tea for Sinus Support. Summer savory, yarrow, garden thyme, marshmallow root, plantain, peppermint leaf, sage and horsetail will take care of your sinuses.
