Asteraceae (The Aster Family)
Yarrow (Achillea millefolium)
"Yarrow has an extensive and interesting literature. The plant or decoctions made from it have been recommended as a cure for sores, toothaches, and diseases of the lungs, bladder, and kidneys; a local anesthetic; a stomach and nerve tonic an ingredient in salads and soups; a tobacco substitute.
Most intriguing is that a random selection of stalks of the humble yarrow was selected by the ancient Chinese sages as the means to consult the oracles of the I Ching or Book of Changes. This compendium arose from mythical antiquity and contains the seasoned wisdom of thousands of years of human history. Most scholars consider the book one of the most important in world literature.
Yarrow is a member of the sunflower family (Asteraceae). The healing powers of yarrow were said to have been discovered by the Greek warrior Achilles. The specific epithet millefolium means "thousand leaved" in botanical Latin."
