The traditional Chinese lunar calendar divides the year into 24 solar terms.?Cold Dew (Chinese: 寒露),?the 17th solar term of the year, begins on Oct. 8?this year.
Cold Dew signals the transition from cool to cold weather. The saying "Cold Dew brings frost" reflects nature's preparation for winter.
During the White Dew season, health-conscious Chinese people often enjoy moxibustion, and the Artemisia argyi from Qichun County, Hubei Province, or Qiai, is particularly favored. It is a China National Geographic Indication product.
Qiai is a premium variety of mugwort known for its thick leaves and high medicinal value. It contains rich essential oils and is widely used in traditional Chinese medicine for its warming and therapeutic properties. The herb is especially effective in moxibustion therapy, helping to promote blood circulation and relieve pain.
