Clears lung fire, treats cough with phlegm, and resolves swelling and toxicity in the throat.
(The *Wuli Xiaoshi* records: Water from salted dried vegetables kills centipedes upon contact. Centipedes will not eat chicken stir-fried with salted vegetables.)

Taste is salty, nature is cool. It treats lung abscess (Fei Yong) accompanied by wheezing and distension. Select aged brine that is clear like spring water, sip it slowly to expectorate phlegm, clear heat, and stop coughing; it truly has the power to revive the dying.
Preparation method
Harvest plants grown for three to five years.

For oil mustard greens (You Bai Cai) planted specifically for seed production, there must be one seed within the old central root. When dry, it rattles when shaken. Extract it by splitting the stalk; it is called "Fen Jin Zi" (Manure Gold Seed). Because it absorbs the power of manure, and the seed within the flower stem absorbs the vital energy of the vegetable, it is highly beneficial to humans. It is called "Gold Seed" to emphasize its value. Seeds from field-grown plants are superior.
Wang Shengyu stated: "Fen Jin Zi is extracted from the dry stalks during seed harvest. It resembles rat droppings, is black, and about the size of a wheat grain. In thousands of stalks, only dozens can be found. This is due to differences in viability; not every stalk produces them."
To treat blood disorders (Xue Zheng), take 3 qian, stir-fry, grind into powder, and mix with plain boiled water to drink. Recovery is immediate.
Highly effective for slow convulsion syndrome (Man Jing Feng) (Wang Shengyu).

It grows on rocks by the sea, similar to Zhi Cai. It is also produced in the coastal areas of Qiongzhou Prefecture. Zhou Haishan's *Huangliuli Guozhi* records: Jijiao Cai (Chicken-foot Vegetable) and Qilin Cai (Qilin Vegetable) both grow on sandy shores by the sea and are also known as Lujiao Cai (Deer-horn Vegetable). It is now commonly used in vegetarian diets; when boiled, it is crisp and crunchy. It can also be boiled down into a paste and eaten in slices.
The *Bencao Gangmu* states regarding Lujiao Cai: Taste is sweet, nature is greatly cold and slippery. Chen Zhishan's *Shiwu Yiji* states: Taste is slightly salty, nature is neutral, and it has significant phlegm-resolving functions. Li Shizhen (Binhu) cited Meng Shen, claiming it has slight toxicity, should not be consumed long-term, and can trigger chronic diseases. Furthermore, its indicated treatments only list resolving food stagnation, pediatric bone-steaming fever, treating Dan Shi heat accumulation, and relieving facial toxicity. Why is its efficacy so misunderstood? Here, I specifically highlight it. Zhu Paishan's *Ganyuan Xiaoshi* records: Shihua Cai (Stone Flower Vegetable) grows among sand and stones at sea, is two or three cun high, and resembles coral. There are red and white varieties. After washing away sand and soil, boiling it forms a paste, which is excellent when pickled with vinegar or sauce. Another variety, fine as ox hair, is called Niulao Shihua (Ox-hair Stone Flower), with a slightly inferior taste. This refers to what Guo Pu described in his *Hai Fu* as "Tu Rou Shi Hua".
Taste is salty, nature is neutral. It resolves phlegm miraculously and can transform all phlegm accumulations, epigastric fullness, hemorrhoid toxins.
I (Zhao Xuemin) note: The *Shengjing Zhi* records Longxu Cai (Dragon-whisker Vegetable) grows on rocks in the southeastern coastal areas. It grows in clusters, resembling willow roots, up to chi in length, and is white. Soaked in vinegar, it is also a fine vegetable. Locals call it Qilin Cai, produced in the coastal areas of Jinzhou. Lujiao Cai grows in the southeastern sea, as thick as an iron wire, branching like deer antlers, purple-yellow in color. Dried, it becomes a delicacy; washed and tossed with vinegar, it retains its fresh flavor. It is currently available in Jinzhou. According to local gazetteers, they appear to be one species with two varieties.
Shihua Gao (Stone Flower Paste) Mao Shihong's *Yangsheng Ji* records: For those who work hard or indulge in alcohol and desire, sudden external hemorrhoids may occur, causing pain and difficulty walking.
Taking this remedy, whether resulting in one bowel movement or none, immediately relieves pain and allows walking; combined with topical applications, it can cure the root cause. Use one liang of Qilin Cai, wash off dust, boil in natural spring water until dissolved, and mix with five qian of white sugar to consume. This prescription was passed down by Li Zhiyun, the Judicial Intendant, to a monk at Lingyin Temple. Xiao Chengzi, a resident of Hangzhou, suffered from this condition. The visiting monk transmitted this formula, after which he recovered promptly. I recorded it and have since treated several patients with good results.
