Pure honey
Coconut oil
Flour
Napkin
Medical stickers
Mix 1 teaspoon of flour with honey, add a little warmed coconut oil and mix it, apply it on a napkin, stick it in the middle of your chest and fix it with a medical tape. Adults can use it overnight. However, children should not be exposed to the tape for more than 2-3 hours. From the first patch, it shows obvious results in suppressing cough and expectorating phlegm.
