Take 1 cup the breast/other milk in a vessel, simmer for 5-10 minutes with a little turmeric and add a speck of sea salt when look warm and give it to child. This moistens the phlegm and cough eases. Another health drink in these circumstances with which all naturopaths agree is lemon juice with a little salt and honey, sufficiently diluted. 1/4 lemon, 1 tsp honey, 2 pinch sea salt, 100 ml warm water. Moistens and helps throwing out phlegm. Hence many say:"it causes cold". In reality it cures cold.
