How arrogant to demand that someone show you the proof of the goodness of chicken essence! You can jolly well google for the proof yourself! It is your own loss if you are so stubborn and cynical.

I have been in nursing in Intensive Care for well over20 years, and I can attest to the rapid healing and recovery of patients whom I always advise to take chicken essence.
The little bottle of chicken essence may look innocuous, but I can assure you it is chockful of restorative nutritive elements, many of which are not understood yet.
Taking commercial essence of chicken is not the same as home brewed chicken soup. The latter is usually very oily.
