Iodine Painting: A Natural Remedy for Sore Throat

If you're grappling with a painful sore throat and exploring natural remedies, you might be surprised to learn about iodine painting. While iodine is a well-known antiseptic for external wounds, its potential as a natural sore throat remedy, applied externally, is a lesser-known but historically significant practice.

This article dives into how external iodine application may help soothe a sore throat, provides clear instructions for safe use, and shares real-life experiences from those who have tried it.

⚕️ Important Medical Disclaimer: Iodine & Thyroid Health

Iodine is a powerful mineral that interacts directly with your thyroid. While this article discusses external application, systemic absorption can occur. If you have any thyroid condition (especially Hashimoto's, hyperthyroidism, or an undiagnosed thyroid issue), are pregnant, breastfeeding, or taking medications, you MUST consult your doctor before using iodine. This information is for educational purposes and is not a substitute for professional medical advice.

How Iodine May Help a Sore Throat (External Application)

Iodine is a vital trace mineral, but when applied topically, it offers distinct properties that may benefit a sore throat:

  • Antimicrobial Action: Iodine is a well-established broad-spectrum antiseptic, effective against bacteria, viruses, and fungi. When applied to the skin over the throat area, it's believed to help combat localized infection.
  • Anti-inflammatory Effects: Some proponents suggest that iodine can help reduce inflammation on contact, which could alleviate the swelling and pain associated with a sore throat.
  • Potential Systemic Support: For individuals with iodine deficiency, topical application can lead to some systemic absorption. Adequate iodine levels are essential for healthy thyroid function, which in turn supports overall immune health and metabolic regulation, potentially aiding the body's natural healing processes.

The theory behind "iodine painting" for a sore throat is that these properties work synergistically to address the underlying infection and reduce symptoms.

Types of Iodine to Use for Sore Throat Painting

When considering iodine for external use, it's important to choose the right type:

  • Povidone-Iodine (Betadine): This is the most common and safest form for topical antiseptic use. It's often brown but less staining than elemental iodine.
  • Lugol's Iodine: A solution of elemental iodine and potassium iodide. It is potent and traditionally used for internal supplementation, but can also be diluted for external use. It will stain brown.
  • Tincture of Iodine: Contains elemental iodine and potassium iodide dissolved in alcohol. It's a strong antiseptic but can be irritating and staining.
  • Decolorized Iodine: This formulation is designed not to stain skin or fabric, making it a convenient option. It works by having the iodine in a complex that breaks down and releases the iodine when it comes into contact with the skin's natural acids, providing antiseptic action without the color.

Recommendation: For convenience and minimal staining, **decolorized iodine** (also known as "white iodine" or "colorless iodine") is often preferred by those trying this remedy. It's typically available online or at pharmacies.

Iodine Painting for Sore Throats: Step-by-Step Guide

This method involves externally applying iodine to specific areas of the skin.

What You'll Need

  • Decolorized Iodine (preferred) or a mild Povidone-Iodine solution
  • Cotton swab or clean applicator
  • Optional: Moisturizer (to prevent dry skin)

Application Areas:

  • Neck/Throat Area: Apply directly to the skin on your neck, around the areas where you feel soreness or notice swollen glands.
  • Wrist Veins: Some users report applying it to the veins on the inside of the wrists, where blood vessels are closer to the surface.

Instructions:

  1. Clean the Skin: Ensure the application area on your neck or wrists is clean and dry.
  2. Apply Iodine: Dip a cotton swab into the iodine solution. Gently "paint" a thin layer of iodine over the designated skin area. You don't need to rub it in heavily.
  3. Let it Dry: Allow the iodine to air dry completely before dressing, especially if using a colored solution to avoid staining clothes.
  4. Frequency: Apply daily. Continue for a few days, or until the soreness subsides. Discontinue use if any irritation occurs.

Real-Life Experiences: Iodine for Sore Throats

Many Earth Clinic readers have shared positive feedback regarding iodine painting for sore throats:

"Iodine cured my swollen saliva/throat glands after 2 horrible nights of restless sleep... I painted the wrists and throat areas. I took a one hour nap and already felt better. The prior two days, it hurt to swallow, it was horrible to eat or drink... By 2 pm, I was at a soup and salads (buffet restaurant) enjoying soup, more fruit, drinking. It pretty much took care of my sore throat and swollen glands."

— Renee, reporting fast relief

"I had a severe sore throat recently (I could not even swallow) and my good friend suggested painting the inside of my wrist with iodine. I thought she was crazy. But it worked! The pain was completely gone the next morning. Shortly thereafter my son became sick with a bad cold. Although she recommended the iodine for a sore throat, I used it on my 3-year old and the next day he was 100% better. I googled iodine cures and discovered this site. I am convinced!"

— Quita, surprised by the effectiveness

The Importance of Iodine in Our Diet

Beyond its topical use, iodine is a crucial dietary mineral for overall health:

  • Thyroid Hormone Production: Iodine is essential for the thyroid gland to produce hormones that regulate metabolism, energy levels, and growth.
  • Goiter Prevention: In the 1920s, the widespread addition of small amounts of iodine to table salt in the US significantly reduced the prevalence of goiters (enlarged thyroids) caused by iodine deficiency.
  • Immune Function: Adequate iodine levels support a healthy immune system, which is vital for fighting off infections like those that cause sore throats.

While external iodine painting may lead to some absorption, it is not a primary method for addressing dietary iodine deficiency. Consult a healthcare provider for proper assessment of iodine levels and appropriate supplementation if needed.

⚠ Precautions & Contraindications

Iodine is a potent substance. Exercise caution and always consult a healthcare professional before using it, especially if you have any pre-existing conditions or are on medication.

  • Thyroid Conditions: **DO NOT use iodine if you have Hashimoto's Autoimmune Thyroid Disease, hyperthyroidism (overactive thyroid), or any other thyroid disorder** without strict medical supervision. Iodine can significantly impact thyroid function.
  • Allergies/Sensitivity: Discontinue use immediately if you experience skin irritation, rash, itching, or any allergic reaction.
  • Pregnancy & Breastfeeding: Iodine can cross the placenta and enter breast milk. Avoid use unless specifically directed and monitored by a doctor.
  • Medication Interactions: Iodine can interact with certain medications, including antithyroid drugs, lithium, and ACE inhibitors. Consult WebMD or your pharmacist for a comprehensive list of potential interactions.
  • Systemic Absorption: While applied externally, iodine can be absorbed through the skin and affect your body systemically. Avoid excessive or long-term application.
  • Children & Elderly: Use with extreme caution and only under medical guidance for children and the elderly, who may be more sensitive to iodine's effects.

Frequently Asked Questions about Iodine Painting

What type of iodine is best for painting?

Decolorized iodine is often preferred for its convenience as it doesn't stain skin or clothing. Povidone-iodine is also an option but can leave a temporary brown stain.

Can I use regular table iodine internally?

No. "Iodine painting" is an external application. Do not ingest topical iodine solutions. For internal supplementation, consult a doctor about appropriate forms and dosages.

How quickly does it work?

Many users report relief within hours to overnight. Individual results can vary based on the severity of the sore throat and individual response.

Will it stain my skin?

Colored iodine solutions (like Lugol's or tincture of iodine) will temporarily stain your skin brown. Decolorized iodine will not.

When should I see a doctor for a sore throat?

Always consult a doctor if your sore throat is severe, accompanied by fever, difficulty swallowing or breathing, a rash, lasts more than a few days, or if you have any underlying medical conditions.

Iodine Painting

My daughter had a sore throat for two nights, so I painted her throat - she thought I was crazy, but then had instant relief! We left it on all night while she slept and she woke up perfect! My throat started getting a little irritated feeling the next night so I did the same, it's better, certainly not worse - probably could have painted certain areas a little more so I will try again tonight. Thank you!

iodine for sore throat: I use iodine at the first sign of a sore throat. Works every time. Rub the iodine on your neck around the areas that it hurts inside.( I get a lot of only hurts on one side sore throats) Also the veins on the inside of your wrists........ these are closest to the skin surface, rub some on them as well...

Iodine to cure sore throat- It didn't work for me! I was so surprised and a little skeptical because so many were saying all you do is rub some iodine on your wrists and neck. I've had a sore throat for 4 days now and I tried it in desperation, but nothing happened. I have a big presentation tomorrow and all I have to show for my herbal remedy to cure my excurciatingly sore throat are yellow neck and wrists! Maybe I did it wrong, but gargling 1 tsp of the Apple Cider Vinegar in a glass of warm water worked better for me!!

I believe it only works at the first signs of infections, is that correct? Also, whats the dosing? how often can you do this and with how much iodine? how much is too much?

Greetings gb,

Some of these sore throats infections come on rather quickly as during COVID. For me, It only takes minutes for the iodine painting to chase a sore throat once applied to that area.

If the iodine painting does not work in minutes, I run for the garlic. It is often a sure hit. A couple of chews on one clove of garlic, or at least a few chops with the knife, and down the hatch.

I always have a nice cold glass of water ready to keep it moving in the right path. Sometimes I simply make the lemon garlic tea that people often talk about on EarthClinic. So if the iodine is slow, toss in the garlic.

For almost 3 days my daughter was complained of her throat feeling like she was swallowing knives. Nothing would take it away. After having tried the egg whites for her fever and it working I came back to this site and sure enough - a remedy for a sore throat...IODINE! I put some on her wrists and on the sides of her throat. It took a little bit - like hours, but her sore throat went away and has not returned since! It has been almost a week now! Thanks again for the wonderful remedies!!

Iodine for Sore Throats/Ear Aches. I'm trying this for the very first time. Let me add this word of caution: KEEP TOWELS HANDY! Wherever you normally sit - say, a couch or favorite easy chair - place towels where your wrists and hands would normally rest. This is especially important if, like me, you sweat profusely even when still. I also suggest wearing clothing that you won't mind possibly getting stained, as the iodine WILL get all over.

Iodine cured my swollen saliva/throat glands. After 2 horrible nights of restless sleep. i found this website in searching for a cure (non-prescription) Iodine was suggested. So about noon today, painted the wrists and throat areas. I found Iodine at a local drug store. It was under $2. I took a one hour nap and already felt better. The prior two days, it hurt to swallow, it was horrible to eat or drink, burning sensation during both. I ate watermelon and when i would drink i would drink as fast as possible. by 2 pm i was at a soup and salads (buffet restaurant) enjoying soup, more fruit, drinking. it pretty much took care of my sore throat and swollen glands. i read here that it takes care of skin tags. i placed iodine on the 3 i have and hopefully they will be gone. i will report back as to whether or not it works, but as far as the initial success and how great i feel, i have a positive outlook.

the Iodine cure worked the best, at first i thought it was weird trying to cure something that was affecting your body at the throat and cure it by painting iodine at the wrists. i also tried it because i had iodine at the time. overall it was the best cure.

Putting Iodine on my wrists and throat did a wonder. I'm picky when it comes to tasting juice or vinegar, so the iodine was perfect!

For younger children, try a spoonful of any kind of thick syrup. I remember when I was younger it worked every time in relieveing a sore throat, but doesn't work now. If you have kids with a sore throat, this might not be the best way to cure it, but it is the one your kids will probably like the most.

Iodine definitely works for me, however, I find it best to use the clear "decolorized" iodine, available at most drugstores. I paint it on the inside of the wrists (where the veins are closest to the skin) and on the sides of the throat.
