How to make an iodine grid?
An iodine grid should be drawn on the skin using a cotton swab — the kind typically used for ear cleaning. Dip the swab in a 5% iodine solution and draw vertical and horizontal lines on the body. The ideal “cell” size of the grid should be about 1 cm x 1 cm.
As iodine penetrates through the skin into the muscle tissue and blood vessels, it damages pathogens by denaturing their proteins. The grid’s secret lies in the spacing of the “cells,” which separates groups of bacteria and causes them to die off quickly. Iodine is particularly effective against bacteria that enter the body through skin pores.
Iodine grid for iodine deficiency
According to statistics, nearly a third of the world’s population suffers from iodine deficiency, which leads to thyroid gland disorders.
To determine whether your body is getting enough iodine from food, no tests are needed — simply draw an iodine grid on the inner thigh.
- If even a trace of the grid disappears within three hours, you should consult a doctor and ask for effective iodine supplementation.
- If the iodine takes 6–8 hours to absorb, this indicates mild deficiency that can be corrected by consuming iodine-rich foods like sea fish, seafood, seaweed, etc.
- In completely healthy individuals, the grid fades only after about 24 hours.
Iodine grid for cough
Regardless of the cause of a dry cough, an iodine grid helps localize inflammation at an early stage. As it penetrates the skin and blood vessels, it boosts circulation. However, an iodine cough grid is only recommended when body temperature does not exceed 38°C.
- The grid can be drawn on the throat (in case of sore throat) or chest (for bronchitis or pneumonia).
- If your skin is sensitive, try a small patch first. If there’s no burning or itching after 10–15 minutes, you can proceed with a full grid.
- The throat grid can be used twice a day — morning and evening.
Iodine grid for colds

Iodine grid for bruises
