Glandulars are concentrates of raw animal organs.  They are used in addressing the imbalances of metabolic organs.  Glandulars supply animals with nutrients that wild animals get from eating the glands and organs of other animals, and so strengthen organ weaknesses and deficiencies.  They can be used as an aid in healing organs or reversing organ damage.  Glandular supplements are used to remedy minor organ imbalances and can actually reverse organ damage.
