When it comes to fighting the flu, colds, and especially stubborn throat illnesses, I have found that sometimes the simplest remedies are the most effective. For more than 20 years, Lugol’s solution—a pharmacy iodine-based preparation—has been my go-to remedy for throat ailments, and I can confidently say it’s one of the best-kept secrets for supporting your immune system and treating infections quickly and safely. In this article, I want to share how I use Lugol’s for flu, colds, chronic fatigue, throat pain, and more, as well as the important precautions you should know.

My Story: How Lugol’s Solution Saved Me From Persistent Throat Illnesses
My journey with Lugol’s solution began decades ago, when I was searching for a reliable way to relieve sore throats that seemed to come with every cold and flu season. After struggling with recurring infections and trying countless remedies, a friend recommended Lugol’s solution. I was skeptical at first, but after following a simple regimen for just a couple of weeks, I noticed a dramatic improvement. The burning, scratchy throat that used to linger for days would disappear within a day or two. Over the years, Lugol’s has become a staple in my household medicine cabinet—not just for colds and flu, but for a host of other health issues.
How to Use Lugol’s Solution for Flu and Cold Treatment
If you feel a cold or the flu coming on, you can use this simple remedy to reduce symptoms and support your immune system:
- Dissolve 1 teaspoon of apple cider vinegar and a little honey in a cup of boiling water.
- Add 1 drop of Lugol’s pharmacy solution (available over-the-counter).
- Stir well and drink the entire mixture after dinner.
Repeat this regimen for 10 to 15 days. Not only will you drive away the infection, but you’ll also strengthen your immune defenses, making it less likely for you to fall ill again.
For Sore Throat
If you feel the first signs of a sore throat or swollen tonsils, treat them with Lugol’s—but do not dilute it with water. Yes, Lugol’s has a strong, unpleasant taste and can sting a bit, especially if your throat is already irritated. However, the results are worth the discomfort. Lugol’s works fast and effectively, so much so that you’ll soon forget about the initial unpleasant taste.
Treating Chronic Fatigue: Zalmanov’s Recipe
Professor Zalmanov, a respected physician, believed that every illness gives some kind of warning sign before becoming serious. These can range from impaired vision, breathing difficulties, or even more serious illnesses like heart disease.
Here’s Zalmanov’s simple recipe for boosting energy and supporting general health:
Recipe 1:
- In a cup of water, add 1 teaspoon of apple cider vinegar and 1 large drop of Lugol’s solution.
- Sip the mixture slowly during meals, alternating with sips of hot tea.
Recipe 2:
- Take Lugol’s solution twice a week (on Tuesdays and Fridays), 1–2 drops once per day.
- If you weigh 65 kg or less, take 1 drop.
- If you weigh more than 65 kg, increase the dose to 2 drops.
During epidemics, increase frequency to three times a week (Monday, Wednesday, and Friday), 20 minutes before meals.
Prostatitis and Immune Support
For men dealing with prostate inflammation:
- Mix 1 teaspoon honey, 1 teaspoon apple cider vinegar, bee pollen, and 1 drop Lugol’s solution into a cup of warm boiled water.
- Let the mixture rest for 2–3 hours, then drink before bedtime.
- The recommended course of treatment is 1.5 months.
Lupus, Thrombosis, and Varicose Veins
If you’ve had lupus or want to prevent complications like thrombosis or varicose veins, take 2 drops of Lugol’s solution in a glass of water, morning and evening, for one week.
Afterwards, drink a glass of beet kvass (fermented beet drink) three times a day for the next week.
Then, alternate between Lugol’s and a supplement called Jodomarin for one month, as described.
Treating Pharyngitis with Lugol’s Solution
Chronic atrophic pharyngitis often co-occurs with atrophy of the nasal mucosa.
Symptoms include dryness, itching, scratchy sensations, dry cough, and rapid voice fatigue.
Symptomatic treatment:
- Rinse the throat with alkaline solutions and oil.
- Use inhalations with alkaline solutions.
- Lubricate the throat lining with Lugol’s solution in glycerin.
- Take Vitamin A and a 3% potassium iodide solution internally.
Chronic catarrhal and hypertrophic pharyngitis can cause persistent throat discomfort, a feeling of a foreign body, mild pain on swallowing, and excessive mucus.
Treatment:
- Rinse and inhale with alkaline solutions.
- Lubricate the throat twice daily with Lugol’s in glycerin.
Pharyngomycosis (fungal infection):
- Usually chronic and asymptomatic but sometimes causes a foreign body sensation in the throat.
Precautions and Contraindications
As with any iodine-based preparation, Lugol’s solution is not for everyone. Avoid or use with caution if you have:
- Hypersensitivity to iodine
- Severe liver or kidney disease
- Hyperthyroidism
- Herpetiform dermatitis
- Children under 12 years old (use only under doctor’s advice)
Final Thoughts
Lugol’s solution, with its simple composition and strong antiseptic power, can be a life-saver when it comes to treating colds, flu, and sore throats. With over 20 years of personal experience, I can confidently say it is one of the most effective natural remedies I have tried. But, as with all powerful remedies, it’s important to use it wisely, pay attention to dosage, and consult your healthcare provider if you have any doubts or pre-existing conditions.
Here’s to your health—may you stay flu-free, strong, and ready to face each season with confidence!
