Background (
Hongshan culture) jade ornament in the form of a curled
pig dragon Depictions of Chinese dragons (龍,
lóng) first appear in the archaeological record circa 3000 BC, before any literary descriptions appear. Dragon worship may have its origin in constellations associated with the lengthening days and rainfall in spring, later being given more abstract meanings. However, "the dragon flourished in art without a set of specific associations."
Ancient and traditional use Dragon bones have been prescribed in Chinese medicine since at least the
Shennong Bencaojing, composed circa 100 AD. There is historical discussion regarding the origin of long gu recorded in the
Bencao Gangmu, which compiles a wide variety of Chinese medical sources. The
Mingyi bielu claims that dragon bones are found in
Jin and around
Mt. Tai, and that dead dragons can be located in riverbanks and caves throughout the year; while
Tao Hongjing states they can be found in
Liang, Yi, and Ba. Lei Xiao reports that bones from Tanzhou,
Cangzhou, and
Taiyuan are of the highest quality. There was debate as to whether long gu were from dead or living dragons, and whether they were bones or secretions.
Li Shizhen listed several subcategories of dragon material, including tooth, horn, brain, fetus, and saliva. Fr. d'Incarville, a French Jesuit, noted that "petrified bones" were among the pharmacopeia sold by druggists in
Beijing in 1751. However, he did not refer to these as dragon's bones. Robert Swinhoe described the use of dragon's teeth in 1870: Shanghai is a great center for [fossil trade]; and the raw article can be procured here in quantity. In other large towns you can only get the prepared drug in a calcined state. These fossils are called
Lungche, or 'Dragon's teeth;' and the idea about them is that in olden time the world consisted of monsters who were incessantly fighting and killing one another [...] The monsters were large and powerful brutes; and in their teeth and bones existed their strength; hence the remains of these ground to powder and taken internally must give strength to the weak invalid. In 1885, 20 tons of fossil bones came through Chinese ports. Searching Chinese pharmacies for new fossil specimens was "an established stratagem of fossil-hunters in the Far East." Western investigation of dragon bones led to the discovery of
Peking Man and
Gigantopithecus blacki.
Wang Yirong identified the ancient Chinese
oracle script on long gu in 1899. == Use ==
