(Recorded in the Middle Grade of *Bie Lu*)
[Correction] The herb "Tianliao" (Heavenly Smartweed), listed as "known name but unused" in *Bie Lu*, is merged here.
[Names] Hongcao (pronounced like "Xie"), Longgu (also written as "Gu"), Youlong (from *Shijing* / *Classic of Poetry*), Shilong (from *Bie Lu*), Daliao (Large Smartweed).
Li Shizhen states: This smartweed is very large and its flowers are abundant and bright red, hence it is called "Hong" or "Hong". "Hong" also means large. In *Bie Lu*, it was listed under "known name but unused". In the herbal section, there is an entry for "Tianliao", stating it is also known as Shilong and grows in water. Chen Zangqi explained: Tianliao is the same as Shuihong (Water Hong), also known as Youlong and Daliao. Based on this, the two entries refer to the same substance; one refers to its fruit, and the other to its stems and leaves. They are now combined into one entry.
[Collection and Explanation] *Bie Lu* states: Hong grows beside water, resembling Maliao (Smartweed) but larger, and its seeds are harvested in May.
Tao Hongjing states: It is now abundant in low-lying wetlands, looking very much like Maliao but growing taller. The *Shijing* mentions "Youlong in the marshes"; Guo Pu commented that this is Longgu.
Su Song states: Hong is Shuihong, resembling Liao but with larger leaves, colored red and white, growing over a zhang high. *Erya* states: Hong is Longgu. The larger variety (pronounced like "Gui").
Li Shizhen states: Its stems are as thick as a thumb and hairy. Its leaves are as large as those of Phytolacca acinosa (Shanglu). The flower color is light red, forming spikes. In late autumn, the seeds mature; they are flat and small, resembling sour jujube kernels, with a dark red-black outer shell and white flesh. The taste is not very pungent, and it can be eaten after cooking or stir-frying.
[Properties and Flavor] Salty, slightly cold, non-toxic.
[Therapeutic Actions] Treats Xiao Ke (Wasting-Thirst / Diabetes), clears heat, brightens the eyes, and tonifies Qi (*Bie Lu*).
[Attached Prescriptions] One old prescription, one new prescription.
Luo Li (Scrofula / Cervical Tuberculosis) already ulcerated: Take an appropriate amount of Shuihong seeds. Fry half slightly and use the other half raw. Grind them together into powder. After meals, take 2 qian mixed with good wine, three times daily.
Pi Pi (Abdominal Masses) with bloating and hardness like cups or bowls: Take 1 sheng of Shuihong flowers and seeds, grind separately. Also prepare 30 cloves of single-clove garlic (peeled) and one fresh dog brain. Apply externally for two or three times. If pus discharges, do not be surprised. Still assess deficiency and excess. Every day, administer Qianshi Baibingzi, Zishuang Wan, Taqi Wan, and Xiaoji Wan alternately to promote purgation and dissipate accumulation. Continue for half a month, or one month for severe cases, without fail to recover. Those with panting and fullness have Excess patterns; those without panting have Deficiency patterns. (*Lin Shi Jingyan Fang*)
Flowers
[Therapeutic Actions] Disperses blood, resolves accumulations, and relieves pain (Li Shizhen).
[Attached Prescriptions] Three new prescriptions.
Stomach Epigastrium Pain due to Blood and Qi Stagnation: Take a large handful of Shuihong flowers. Add two zhong of water, decoct to one zhong, and drink. This is a frequently verified prescription by Mao Juzhuang, Baihu. (*Shui Ji Yan Fang*)
Heart Qi Pain: Grind Shuihong flowers into powder. Take 2 qian with hot wine. Another method: For males, decoct with equal parts water and wine; for females, decoct with equal parts vinegar and water. A thirty-year-old woman suffering from this condition recovered immediately after one dose. (*Zhai Xuan Fang*)
Abdominal Accumulations: Take one bowl of Shuihong flowers or seeds. Add three bowls of water. Decoct using mulberry wood fuel, first with strong fire then mild fire, until it forms a paste. Spread the paste according to the size of the accumulation and apply externally. Simultaneously, take the paste mixed with wine. Avoid greasy, rich, and fishy foods. (*Liu Songshi Bao Shou Tang Fang*)
