At least iodine is natural and should not be dangerous if used carefully within limits.
Iodine does not occur in its elemental and most toxic form in nature-- it is a highly reactive and caustic substance, and is never taken internally. Iodides occur in small quantities as part of natural salt and in ocean fish, seafood, etc. Taken orally and in those quantities, it is necessary for good health, and our bodies have evolved to absorb it orally and excrete any excess. You are circumventing the body's natural defences. Anal absorption is typically much higher than oral absorption. And enteric tissue is much more easily damaged than skin or the mucus-coated stomach tissue.
As for "natural" -- well, strychnine is natural - that doesn't mean that it's healthful to ingest.
Here's the toxicology profile if you're interested:
http://www.atsdr.cdc.gov/toxprofiles/tp158-c3.pdf
The effects of oral iodine ingestion acute overload include death, and it's not a pretty death: "Symptoms of toxicity that have been observed in lethal or near-lethal poisonings have included abdominal cramps, bloody diarrhea and gastrointestinal ulceration, edema of the face and neck, pneumonitis, hemolytic anemia, metabolic acidosis, fatty degeneration of the liver, and renal failure." (section 3.2.2.1)
The effects of sub-acute systemic accumulation from chronic oral ingestion of iodides have "adverse effects on a wide variety of other organ systems can result from iodine-induced disorders of the thyroid gland, including disturbances of the skin, cardiovascular system, pulmonary system, kidneys, gastrointestinal tract, liver, blood, neuromuscular system, central nervous system, skeleton, male and female reproductive systems, and numerous endocrine organs, including the pituitary and adrenal glands." (section 3.2.2.2)
Other adverse effects include autoimmune disease, immune reaction/fever, allergies, skin reactions (3.2.2.3), neuromuscular disorders (3.2.2.4), and thyroid cancer(3.2.2.7).
I'm sorry I cannot be supportive of your endeavor. I thought it would be irresponsible if I let it go without comment.
