Scientists credit Yarrow with at least minor activity on nearly every organ in the body. Early Greeks used the herb to stop hemorrhages. Yarrow was commonly used by Native American tribes for bleeding, wounds, and infections. It is used in Ayurvedic traditions and traditional Chinese medicine credits yarrow with the ability to affect the spleen, liver, kidney, and bladder meridians, or energy channels, in the body. Yarrow may also be used in tea or form for bleeding ulcers, heavy menstrual periods, uterine hemorrhage, blood in the urine, or bleeding from the bowels. Yarrow compresses are effective for treating bleeding hemorrhoids.
Yarrow is often classified as a uterine tonic. Several studies have shown that yarrow can improve uterine tone, which may increase menstrual blood flow when it is irregular or scanty, and reduce uterine spasms, which reduces heavy flow in cases of abnormally heavy menstrual flow.
Yarrow preparations can relieve symptoms of menstrual cycle and uterine disorders, such as cramps and endometriosis.
Yarrow also has antiseptic action against bacteria. The bitter constituents and fatty acids in yarrow are credited with promoting bile flow from the gallbladder, an action known as a cholagogue effect. Free-flowing bile enhances digestion and elimination and helps prevent gallstone formation. Because of these anti-inflammatory, antispasmodic, and cholagogue actions, yarrow is useful for gallbladder complaints and is considered a digestive tonic.
Yarrow has a drying effect and can be used as a decongestant. Sinus infections and coughs with sputum production may be improved by yarrow, especially when mixed with equal parts goldenseal. Note that cough with ample sputum production may be a sign of bronchitis or pneumonia and requires the attention of a physician.
Yarrow's astringent action is helpful in some cases of allergy, in which watery eyes and nasal secretions are triggered by pollen, dust, molds, and animal dander. Yarrow also has long been used to promote sweating in cases of colds, flu, and fevers, thus helping you get over the simple infections.
