re: anise seed tincture for treatment of nonproductive coughs. A nonproductive cough is another name for a dry cough which does nothing to move phlem from the throat and lumgs. This is often a precursor to a more serious ailment like pneumonia. It is of the utmost importance that you remove the excessive phlem from your system. I have found that the best expectorant that I can find is made by placing five tablespoons anise seeds into 1 cup of rum. I take no more than 2 teaspoons of this as needed to induce a cough which allows for the mucus to be removed from the body.
A note to nursing mothers who have problems with milk production; a good side affect of anise is that it increases milk production in lactating mothers. I know this for a fact as my last child was born when I was 40 and I had problems producing milk sufficient to meet my child's needs. Be cognisant of the fact that you do not want to over do it with alcohol if you are nursing as this would be counter productive to the health and well being of the child who depends on you for nourishment. I used an anise tea when I was nursing it works well for increasing milk production.
