Ground ivy is mostly ignored by modern herbalists in favor of the better known members of the mint family, but that does not mean this common little ground weed is not worth knowing. Search the term ground ivy on the internet and you will find a lot of information on how to kill it once it has invaded your lawn Primarily it is used as a bitter tonic, as a nutritive tea high in Vitamin C, and as an excellent remedy for a stubborn cough.
Use 1/4 cup of the chopped whole herb for each cup of tea. Cover with boiling water and steep in a covered bowl until room temperature. To use as a bitter tonic sip a half cup of chilled, unsweetened tea 1/2 hour before eating. The fresh leaf can be bruised and applied to ease cuts and insect bites. It is an invasive weed but if your gardening friends have some in their yards, you can always volunteer to go pull some for them.
