Iodine/KI blends are used in some sugical scrubs and germical cleansers.
In preparing this, the KI is first dissolved in some water, and the iodine
added. This mixture is stirred slowly until the iodine dissolves (as the
iodine dissolves, it forms reacts with the iodide to produce the iodate
state which appears as a very dark, translucent, purplish-brown
solution). If you do heat this, be very careful - iodine fumes can be
generated, and the iodine fumes can be especially dangerous in a confined
area without adequate ventillation.

If you're using this only to get the iodine as a treatment for goiter, why
not use a solution of KI (iodine has germicidal properties, and the KI is
used to stabilize the iodine, not the other way around).
