The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration.
However, there has been research in this area. In germany, frankincense (boswellia serrata) is aparently considered a standard treatment for cancer in brain because it is one of the few substances believed to cross the BBB. Wormwood (Artemisia absinthium) is another possibility.owever, there has been research in this area.

The BBB is distinct from the quite similar bloodâcerebrospinal-fluid barrier, which is a function of the choroidal cells of the choroid plexus, and from the bloodâretinal barrier, which can be considered a part of the whole realm of such barriers. Several areas of the human brain are not on the brain side of the BBB. small number of regions in the brain, including the circumventricular organs (CVOs), do not have a bloodâbrain barrier. The bloodâbrain barrier occurs along all capillaries and consists of tight junctions around the capillaries that do not exist in normal circulation.
