You asked about the best way for women to get iodine into the breasts, uterus, genitals. The medical studies show that getting iodine intravaginally so it contacts the cervix shoots iodine into the right places immediately. I get the feeling iodine goes where it's most needed.
Getting iodine to the cervix has been done in the last 30 years by Drs. Meyers and Wright by painting the cervix. This may be impractical for home use. Also, the doctors want to avoid having iodine contact the urethra where it could sting. Tho in old cases where the urinary plumbing was blocked, iodine was used to clear "strictures."
According to published medical studies, intravaginal progesterone suppositories have been long shown to be the most efficient way to get progesterone absorbed in the right spots. And progesterone is huge in enhancing iodine uptake. This was shown by researchers. So suppositories seem a practical strategy for those of us who are not graceful with a paint brush. I seem to remember some Curezoners freezing iodine with butter for suppositories.
There is no current official recipe other than the picture of the iodine suppositories that used to be for sale. Many iodine suppository regimens appear in 150 year-old medical books as "bougies." You can look it up.

This information has been buried by modern medicine. Again, the convenient disposable suppository molds are about $7 for 100 online. Antique suppository molds are available on ebay if you are into the history of medicine.
Hope this nerdy stuff helps.
If anybody experiments, please report back!
