Achillea millefolium, commonly known as yarrow (/ˈjæroʊ/) or common yarrow, is a flowering plant in the family Asteraceae. Growing to 1 metre (3+1⁄2 feet) tall, it is characterized by small whitish flowers, a tall stem of fernlike leaves, and a pungent odor.
The plant is native to temperate regions of Eurasia and North America. It has been introduced as feed for livestock in New Zealand and Australia. It has some potential uses, including in traditional medicine.
The I Ching or Yijing (Chinese: 易經 Mandarin pronunciation:[î tɕíŋ] ), usually translated Book of Changes or Classic of Changes, is an ancient Chinese divination text that is among the oldest of the Chinese classics. The I Ching was originally a divination manual in the Western Zhou period (1000–750 BCE). Over the course of the Warring States and early imperial periods (500–200 BCE), it transformed into a cosmological text with a series of philosophical commentaries known as the Ten Wings. After becoming part of the Chinese Five Classics in the 2nd century BCE, the I Ching was the basis for divination practice for centuries across the Far East and was the subject of scholarly commentary. Between the 18th and 20th centuries, it took on an influential role in Western understanding of East Asian philosophical thought.
As a divination text, the I Ching is used for a Chinese form of cleromancy known as I Ching divination in which bundles of yarrow stalks are manipulated to produce sets of six apparently random numbers ranging from 6 to 9. Each of the 64 possible sets corresponds to a hexagram, which can be looked up in the I Ching. The hexagrams are arranged in an order known as the King Wen sequence. The interpretation of the readings found in the I Ching has been discussed and debated over the centuries. Many commentators have used the book symbolically, often to provide guidance for moral decision-making, as informed by Confucianism, Taoism and Buddhism. The hexagrams themselves have often acquired cosmological significance and been paralleled with many other traditional names for the processes of change such as yin and yang and Wuxing.
Oracle bone script is the oldest attested form of written Chinese, dating to the late 2nd millennium BC. Inscriptions were made by carving characters into oracle bones, usually either the shoulder bones of oxen or the plastrons of turtles. The writings themselves mainly record the results of official divinations carried out on behalf of the Late Shang royal family. These divinations took the form of scapulimancy where the oracle bones were exposed to flames, creating patterns of cracks that were then subjected to interpretation. Both the prompt and interpretation were inscribed on the same piece of bone that had been used for the divination itself.
Out of an estimated 150,000 inscriptions that have been uncovered, the vast majority were unearthed at Yinxu, the site of the final Shang capital (modern-day Anyang, Henan). The most recent major discovery was the Huayuanzhuang cache found near the site in 1993. Of the 1,608 Huayuanzhang pieces, 579 bear inscriptions. Each of the last nine Shang kings are named in the inscriptions beginning with Wu Ding, whose accession is variously dated between 1250 and 1200 BC. Oracle bone inscriptions corresponding to Wu Ding's reign have been radiocarbon dated to 1254–1197 BC (±10 years). Following the overthrow of the Shang by the Zhou dynasty in c. 1046 BC, divination using milfoil became more common; far fewer oracle bone inscriptions are dated to the Western Zhou. No Zhou-era sites with a comparable cache of inscriptions to Yinxu have been found; however, examples from this period appear to be more widespread, having been found near most major population centers. New sites have continued to be discovered since 2000.
