Kali iodatum, which is also called potassium iodide, may be used as a Homeopathic or used simply as a micro-nutritional (mineral preparation). Homeopathic potencies accredit their strength and efficacy to the electromagnetic signatures of the original substrate; these are scientifically created dilutions and succussions of medicines such that generally not even a molecule of the original substrate or medicine is present in the medicine.

As a Homeopathic or used simply as a micro-nutritional, Kali iodatum has demonstrated effectiveness against the following symptomology: "Whenever the elimination of some effete, imperfectly organized, excessive or abnormal material (from the system) is the (therapeutic) object to be accomplished... whenever it is intended to modify the living elements of the economy."
