Expect to get emotional post-flush. The liver stores a lot of emotions that get released in the flush, and the flush stirs up toxins and hormones that act on mood, especially when they pass the blood-brain barrier.
All of our cells, tissues and major organs have the capacity to store emotional energy. You can see whether the liver is storing anger by the lines in between the eyebrows. If you have deep lines there, consider doing some emotional release work and liver management.
