Strong solution of iodine is corrosive and can cause blistering and necrosis of skin, commonly referred to as chemical burns or irritant contact dermatitis. Iodine has thus been replaced by substances known as iodophores that contain an iodine molecule linked to a large molecular-weight organic compound.
Sweating is then encouraged by increased room temperature, exercise, use of a sauna, or pilocarpine. When sweat reaches the surface of the skin, the starch and iodine combine, causing a dramatic color change (yellow → dark blue), allowing sweat production to be easily seen.
A positive result for the iodine test (starch is present) was a colour change ranging from violet to black; a negative result (no starch) was the yellow colour of the iodine solution.
PVP-iodine and octenidine can stain skin purple, does the reaction create iodine radicals? ... octenidine can release iodine radicals from the PVP complex, resulting in a tissue irritation as well as strong brown to violet discolouration in the border areas.
Povidone iodine can be used both prophylactically during wound cleaning and therapeutically as leave-on application in contaminated chronic and acute wounds. A typical regimen for cleaning is a soaking time of 20 min each, using cycle frequencies of four to eight cycles per day [59].
Based on the available evidence from clinical trials, iodine is an effective antiseptic agent that shows neither the purported harmful effects nor a delay of the wound-healing process, particularly in chronic and burn wounds.
Do not use topical iodine on deep, puncture wounds, animal bites, or serious burns. To do so may increase the chance of side effects. Do not cover the wound to which you have applied topical iodine with a tight dressing or bandage since this may increase the chance of side effects.

Because of iodine's ability to improve thyroid function, through encouraging the production of important thyroid hormones, it can also have somewhat of an indirect effect on improving the functions of both the liver and kidneys, two super vital organs when it comes to detoxification.
Iodine is a common indicator to test for the presence of starch. The light orange-brown colour Iodine solution turns blue-black in colour when it reacts with starch.

Wounds need to be covered so that they can heal properly. When a wound is left uncovered, the new surface cells that are being created can easily dry out. When these important cells dry out, it tends to slow down the healing process. A wound should be covered using a clean bandage.
Based on the available evidence, iodine was an effective antiseptic agent that was not associated with adverse side effects or delays in the healing process, particularly for chronic and burn wounds. The antiseptic effects of iodine were not inferior to other antiseptic agents and did not impair wound healing.
1. When the INADINE™ Dressing colour fades this indicates loss of antiseptic efficacy and the Dressing should be changed. It may be changed up to two times daily in the initial phase or with highly infected wounds or wounds producing large amounts of wound fluid.

As a result, the broad antimicrobial spectrum of iodine may be used topically to control wound sepsis. It can be applied to mucosal surfaces without producing burns. The brown color acts as an indicator of its clinical effectiveness.
Getting a very large dose of iodine (several grams, for example) can cause burning of the mouth, throat, and stomach; fever; stomach pain; nausea; vomiting; diarrhea; weak pulse; and coma.
