Other than with pharmaceutical drugs which are either for cough or high
blood pressure or for any single ailment many plant medicines are much
more complex and can be used to fight so many illnesses that you cannot
decide which are the main applications for that plant. Yarrow is such a
herb, but for me it has one main application: I use it for any deep
nasty cut and I was really impressed, after accidentally snipping my
fingers with the secateurs.
There are many many uses for yarrow, let’s start with the medicinal ones:
- colds and flu
- stomach ulcers
- amenorrhea (the absence of a menstrual period)
- abdominal cramps
- trauma and bleeding
- reduce inflammation
- bleeding ulcers
- heavy menstrual periods
- uterine hemorrhage
- blood in the urine
- bleeding from the bowels
- antibiotic properties
- bleeding hemorrhoids
- relieve pain associated with gynecologic conditions, digestive disorders, and other conditions
Yarrow has a bitter taste. You can add the leaves to salads and omelettes; sparingly so as not to over power the dish. Yarrow also makes an interesting addition to chicken soups and stews. Yarrow flowers make a wonderful aromatic wine.
Yarrow is easy to grow, likes full sun, neglect and a dry spot. There are a lot of ‘improved’ cultivars for the ornamental garden, my guess is, that they might cross with your medicinal yarrow and lessen the effectiveness.
