[Di Dan]
Taste: Acrid (Xin). Nature: Cold. Toxicity: Toxic. Indications: Governs Gui Zhu (a contagious chronic wasting disease), alternating chills and fever, Shu Lou (cervical lymph node tuberculosis), malignant sores, dead muscle tissue, breaks up Zheng Jia (abdominal masses), induces abortion, erodes evil flesh in sores, removes nasal polyps, disperses stagnant Qi and Shi Lin (urinary calculi), expels the fetus. Administration of one Dao Gui (an ancient unit of measurement) results in expulsion. Also known as Qing, also known as Qing Wa (pronounced Wu Wa Qie). Grows in the valleys of Mount Wen. Harvested in August. (Incompatible with Gan Cao / Licorice Root.)
Tao Hongjing states: The genuine product comes from Liang Zhou, resembling a large horse ant, with wings; the counterfeit is transformed from Ban Mao (Mylabris), resembling a soybean. Their therapeutic effects are largely similar, but the genuine product cannot be obtained. This counterfeit can also be used, hence the name "Qing". The character " " is a variant, likely due to historical transmission error. The Commentary on the New Pharmacopoeia notes: Those resembling large horse ants are seen coming from [missing character] Zhou. Those resembling soybeans have not been seen. Ministers Yu Xi et al. according to the Shu Ben Tu Jing record: Collected in February, March, August, and September from grass and vegetables, appearing doubly black, transformed from Yuan Qing (Mylabris phalerata). Yao Xing Lun records: Di Dan can promote the discharge of Luo Li (scrofula) roots via urination or vomiting. Treats nasal polyps. The content of Tu Jing is detailed under the entry for Yuan Qing.
[Ke]
Taste: Salty. Nature: Neutral. Toxicity: Non-toxic. Indications: Governs eye nebula (cataracts/opacities), stops bleeding, generates flesh. It is a bivalve mollusk, size like Abalone (Fou), with yellow-black skin and white bone, used as horse ornamentation. Grows in the South Sea, harvested at any time. (Attached first in the New Pharmacopoeia.)
Hai Yao Ben Cao: According to Ming Yi Bie Lu: Grows in the South Sea, white like a clam. Governs the resolution of nebulae and Jin Nu Rou (protruding conjunctival tissue), applied as scraped powder. There are no other major uses. Lei Gong says: Winter harvest yields those that are white and greasy, with white spiral water patterns. Do not expose to fire, or it becomes useless. When used, scrape with a copper knife, sieve through silk gauze, and grind over a thousand times before use. This substance is not used in women's medicines.
[Qing Ling]
Nature: Slightly Cold. Actions: Strengthens Yin, stops seminal emission.
Tao Hongjing states: There are five or six types. The currently used type has green eyes, also known as Zhu Cheng, colloquially called Hu La. Taoists use it to stop seminal emission. Its eyes can be transformed into green pearls. The remaining yellow, fine, and black varieties are not used in medicine, also known as Qing Ting. Ministers Yu Xi et al. according to the Shu Ben Zhu note: Qing Ting has six legs and four wings, fond of flying beside streams and canals. Ri Hua Zi says: Qing Ting is cool and non-toxic. Strengthens Yang, warms the Water Zang (Kidneys). For medicinal use, remove wings and legs, stir-fry for best effect.
Tu Jing states: Qing Ling was not recorded in old texts regarding its origin provinces. Now found abundantly near waters. There are several types; the green-eyed variety is superior. Yellow, red, and black varieties are not used. The common name is Qing Ting, which is not strictly necessary. Taoists use it frequently.
Yan Yi states: Among Qing Ling, the largest type is known in the Capital as Ma Da Tou. It is green-bodied; females have a ring of jade-green color around the waist. Males should be used. Tao Hongjing considered the green-eyed variety. Within this category, there originally were no green ones; the eyes are all large. This creature originates from water, thus often flies over water. Tang Dynasty poet Du Fu wrote: "Dragonflies skim the water, flying leisurely."
