Yarrow is well known for its ability to help stimulate clotting in cuts and abrasions. It may speed healing, relieve inflammation and reduce the pain of injuries. Yarrow acts as a blood cleanser and is good for colds, fevers, flu, lung disorders, nosebleeds and perspiration. It also helps regulate and improve the function of the liver. It tones the mucous membranes of the stomach and bowels and aids the glandular system. The use of yarrow for healing wounds has evidence to back it up. Research has found yarrow extract to contain slight antibiotic properties that may protect an injury from infection. Yarrow has also demonstrated some antispasmodic properties that work to relax smooth muscles in the digestive tract and uterus. This may help with digestion, as well as menstrual cramps, which was a traditional use. A volatile oil in yarrow known as azulene and related compounds have been shown in studies to have anti-inflammatory properties that also help with wound healing, which generally involves some inflammation. The thujone content in yarrow has a slight sedative effect that has been compared to cannabis. In large doses, thujone can be toxic, but recommended amounts of yarrow appear to be safe. Yarrow reportedly has properties to protect the liver from toxic chemical damage and to treat hepatitis. The properties of each species may be affected by the age and environment in which they are grown, causing differences in chemical components.
