If you have a cut or a wound, yarrow is a superior option to topical antibiotics. Test a small patch of skin before applying yarrow topically. To speed wound healing, apply a tincture topically three times a day. Use one teaspoon dried yarrow in one cup boiled water for ten minutes. Strain, then drink.
Yarrow stimulates the uterine muscles, so avoid using it during pregnancy.
Consider including a few healing plants in your landscape this year. Even if you don't appreciate what they can provide health-wise, you're certain to enjoy their appearance. Consult with your local nursery about which plants work best in your landscape. Bookstores and the internet are another great source of information.
