[Empty Blue (Kongqing)]
Sweet in taste, cold in nature. Primarily treats blindness (Qingmang) and deafness. Brightens the eyes, benefits the nine orifices, unblocks blood vessels, nourishes spirit and mind. Long-term consumption lightens the body, prolongs life, and prevents aging. Capable of transforming copper, iron, lead, and tin into gold. Grows in mountain valleys.
Formed through fumigation with copper liquid, floating and gathering during the three months of spring. Enhances hearing like opening a window, clears vision like parting clouds. Often offered to Golden Immortals (Daoist deities), accompanied by Jade Maidens as legend has it. Broad-minded and lofty in spirit, elegant and graceful in bearing, beautiful as Shao music.
[Cengqing]
Sour in taste, slightly cold in nature. Primarily treats eye pain and stops tearing. Treats wind-bi (Wind-Bi syndrome), benefits joints, unblocks the nine orifices. Breaks down hard accumulations and masses. Long-term consumption lightens the body and prevents aging. Capable of transforming gold and copper. Grows in mountain valleys.
After growing for over eight hundred years, Cengqing is born. The gaze turns inward, accumulating to break down abdominal masses. Beads linked together, layers upon layers. Metal transforms, layer by layer. Opens gates, releases joint constraints, exquisitely merging and condensing.
The *Huainanzi* records: After eight hundred years of blue sky, Cengqing is generated. The commentary on the *Huangting Jing* states: Constantly visualize the light of the sun and moon within the two eyes; when this light merges with the body, one attains true connection. Tao Hongjing says: The shape resembles clusters of Coptis chinensis (Huanglian) linked together. Fei Guanqing records: Layer upon layer leaning against the empty space. Zhou Dunyi's *Taiji Tushuo*: Exquisitely merging and condensing.
[Yuyuliang]
Sweet in taste, cold in nature. Primarily treats cough and upward rushing of qi, alternating chills and fever, restlessness and fullness, dysentery with red and white discharge, blood obstruction, abdominal masses, and high fever. Taken as refined pills, it suppresses hunger, lightens the body, and prolongs life. Grows in ponds, marshes, and mountain islands.
Gu insects transform into flying grains; grain also undergoes feather-transformation. Nourishing like flowing rivers, flourishing spreading across rock crevices. Red scattering like lingering sunset clouds, yellow blowing in the evening wind. Knowing whiteness to distinguish names, the merit of Yu need not be surprised.
The *Zuo Zhuan* records: Grain turning into flight becomes Gu. The biography in the *Book of Jin*: Those who cultivate the Dao all call it feather-transformation. Tao Hongjing says: It has overlapping shells, containing fine powder resembling Polygonum multiflorum spores (Puhuang). Another variety has nodes and is reddish in color. Fan Chengda's poem: Early flowers and late flowers. The *Daodejing*: Know the white. Famous physicians say: Also known as Bai Yuliang. According to the *Shennong Bencao Jing*: It does not refer to Yu the Great himself.
