What is iodine?

Iodine is a naturally-occurring element that is vital for thyroid function. In the United States, iodine is added to table salt and cattle feed to ensure that most people will not develop a deficiency. Prescription-only drugs containing iodine are used to treat thyroid disorders.

Dissolved in a tincture, iodine is also used as an antiseptic to prevent or treat infection of minor cuts or scrapes on the skin, and to prevent infection of surgical incisions.

Iodine solutions and tablets can also be used to purify water from ponds and streams so that it can be safely consumed.
