I have a super cold right now so I'm thankful that I know a little about herbal teas not just tea.
Herbal tea on anisseed is great when you have a cold becouse it makes the expectoration thinner so it's easyer to chough Up.
It have other medicinal properties like it helps if you are gassy and helps against colic if the mother drinks it (if you are breastfeeding).
You make it like this, take about 1tsp of anisseed, if you want you can crush it a little.
Boil your water and pour it over the anisseed. Let it brew for 5 minutes. And if you have a sour throat it's great with honey.
