There are two main biophysical effects had from pulsing. First and most important is the forcing of lymph fluid movement through the main lymph arteries toward where the lymph empties into the bloodstream near the heart. The second effect is the dislodging of microbes from where they are 'stuck' in the body due to electrical attraction. A blast of magnetic energy which creates a pulse of electrical energy in the body tends to break up electrical attractions by equalizing electrical charges.
Many sick people have very sluggish lymph movement and therefore the lymph fluid is somewhat trashy.
A good analogy would be the difference between a fast moving stream with clean water and a swamp with stagnant water. To aid the body in the removal of lymph 'trash' that gets dumped into the bloodstream when you start pulsing I recommend taking blood purifying herbs. Drink 1-2 cups daily right after pulsing.
