It is medically enhanced version of regular bindi, embedded with iodine. It delivers the daily requirement of iodine i.e., 100-150 micro grams, absorption through the skin. These are being supplied in Maharashtra to iodine deficient people, particularly tribals. This initiative is supplemented with iodine pills available at community health centre.
An iodine patch, designed like a regular bindi, is expected to help one lakh tribal women in north-west Maharashtra battle iodine deficiency. Since these tribals don’t consume iodized salt, they are usually deficiency in this nutrient. Almost every Indian woman wears a bindi. Transforming these into iodine patches ensured that women got the required dosage of iodine without making changes to their daily behaviour.
