For example, one of the key ingredients is iodine, usually added as potassium iodide. It is a saline compound that prevents radioactive iodine from entering the thyroid gland in an emergency situation1 . It is often used in combination with medications called anti-thyroid drugs to regulate the production and secretion of thyroid hormones in some people, especially in an overactive thyroid. It has also been observed to have an expectorant action. Hence it helps loosen phlegm trapped in the airways.2.

In an emergency situation due to radioactive exposure, potassium iodide is able to selectively block the absorption of radioactive iodide by the thyroid gland, protecting it from possible damage and reducing the risk of developing thyroid cancer in the long term 3.

Another fact to consider is that iodized radish is usually very rich in calciumpotassiumvitamin C, and vitamins of group B ( B1, B2, B3, B6, and B12 ). This further increases the health benefits of syrup.

That said, here is a recipe to make radish syrup in a few steps.

  1. Wash 4-5 radishes with plenty of water, dry them and cut them into skinny slices.
  2. Take them to a glass container, clean them, and totally dry them.
  3. Cover the radish slices with 15 tablespoons of pure honey (preferably organic).
  4. Add the juice of 1 lemon and 5 drops of liquid potassium iodide (for oral consumption) or, failing that, 2 finely cut garlic cloves. Did you know that garlic is one of the foods with the highest content of natural iodine?6
  5. Stir, cover tightly and marinate in a dark, dry place for at least 24 hours before first use. Since it is not recommended to refrigerate this syrup, it is preferable to remove the radish slices after 2-3 days. This will keep it in good condition for longer.

Note: Even in small doses, avoid taking oral potassium iodide without first consulting your doctor.
