The silk filaments on the orange pulp, sugar-preserved Huazhou exocarp (Huazhou Juhong, 化州橘红), preserved orange cakes, medicinally prepared citrus cakes, green salt-aged tangerine peel (Qingyan Chenpi, 青盐陈皮), and Ju Ling.

*Records of Lingnan* states: The immortal oranges of Huazhou are said to have been planted by the immortal Luo Bian on the belly of a stone dragon, and this tree still exists today. Among them, only one tree is considered the best, specifically the produce from Suzetang; the produce from Qingfenglou ranks second, and that from Hongshu ranks third. The fruit of this tree is not an ordinary orange; its peel is thick and the flesh is sour, making it inedible. Its peel is sliced into five or seven segments, never in even numbers, and each genuine segment can be worth one tael of gold. The annual yield must be reported to higher authorities according to regulations. At the time of harvest, the Governor-General dispatches trusted attendants to supervise the picking and processing. Officials serving in this region rarely get to taste it. Locals say that wherever one can hear the drum beats from the watchtower near the prefecture, the peel produced there is also excellent. Therefore, there are many counterfeits of Huazhou peel, and genuine ones are very hard to obtain.

Guan Han's *Lingnan Casual Notes* states: The orange tree in front of the Huazhou government office bears one fruit per month. Its peel, when used as medicine, instantly resolves phlegm. Later, the tree was broken by the wind and replanted in the same location, but its aroma and flavor changed. Today, what is called "Huazhou Juhong" is mostly counterfeit, made from the peel of Zengcheng fragrant pomelo. It can resolve other things (phlegm) but cannot resolve itself (it is not true orange).

*Yueyu* states: There is one orange tree in the Huazhou government office that bears one fruit per month. Its peel is processed into Juhong, boiled in water and drunk, which instantly eliminates phlegm. It was once offered as tribute to the Emperor. This tree was uprooted by a strong wind, and a new one was planted, but its flavor is inferior. Huazhou formerly produced much Juhong for sale within Lingnan, but the one from the government office was unique.

*Bencao Chengya* states: Oranges and pomelos concentrate their essence in the fruit, and the peel concentrates the essence of the fruit. The peel is distributed with fine pores, resembling human skin. Its meridians, textures, fascia, seeds, and kernels all have specific affiliations. Thus, its medicinal power can transform from descending to ascending, from ascending to combining, and from combining to opening. All various forms and syndromes follow the principles of entering and combining. Therefore, for conditions such as heat accumulation in the chest (Jia Re, 瘕热), failure of water and grain to circulate, obstruction of the spirit-mind, rebellious Qi, and foul odor below the ears, the Qi descends after exiting, demonstrating the subtle efficacy akin to the rotation of the Jade Balance star.

*Shiyao Bianwei* states: The Huazhou Juhong recently arriving from Guangzhou consists of single segments bundled together, cut into diamond shapes, or thirty to fifty segments tied at both ends with red string to form a bunch. The outer peel is pale red, the inner albedo is white, and the surface has bristle-like textures. These are actually pomelo peels, which can also eliminate phlegm. Another type is highly valued by the world; each fruit is divided into five claw-like segments, stamped with the Huazhou seal, named "Five-Claw Juhong." It is also made from pomelo peel and is better than palm-shaped slices. However, compared to the genuine article, it falls far short. Genuine Huazhou Juhong, when decocted, yields a sweet fragrance. If a drop of its juice is added to a spittoon, the phlegm turns into water. This is the superior grade.

The Li family's collection of Suzetang Huazhou Juhong consists of fruits split into seven segments, folded back into seven branches, dried, with a very strong and fragrant aroma. There is a song about Juhong:
"The spiritual mystery of Stone Dragon is unfathomable,
Its head faces the blue sky, its tail hides in the depths.
Sometimes its roar is loud like a goose,
Sometimes it spews sand white as snow.
Its cry may herald the birth of a prime minister,
Or continuous success in imperial examinations.
Prefects walk their usual path,
Fearing strange wonders would frighten the ignorant.
Temples, steles, drums, and fanfare guard its head,
Heavy cauldrons and piled stones fill its cave.
Heaven-born spirituality relies on no proof,
Twisted and curved, it transforms into the orange.
The nature of the orange is warm and neutral,
It can cure cold damage and food stagnation.
Its merit in resolving phlegm and stopping coughs is miraculous.
Whoever first identifies this true dragon vein,
Will find its value beyond gold, hard to seek.
I send word to the world: do not waste it lightly."

Efficacy: Miraculous in treating phlegm disorders, resolves grease and grain food stagnation, awakens the stomach and relieves fullness. Contraindicated for those with Qi deficiency. Resolves crab toxicity.

*Cihui Bian* states: For crab poisoning, decoct and take Juhong.

Grind each separately. Use Quanxie (Whole Scorpion) 14 pieces (remove feet, wash with wine), Yuanzhi Rou (Polygala Root Flesh, processed with Licorice juice), Gouteng (Uncaria Rhynchophylla), Fangfeng (Saposhnikovia Root), Huazhou Juhong, Jiangyi (Ginger Skin), Qianghuo (Notopterygium Root), Fuling (Poria), and Tianma (Gastrodia Rhizome), each 5 qian.

Take one pill each time, washed down with boiled water.

Note: *Baicao Jing* states: Huazhou in Gaozhou Prefecture, Guangdong, produces Chenpi (aged tangerine peel). Those with the white albedo removed are named Juhong, but they are now rare. Locals substitute pomelo peel, selling it outside the region at a low price. The method of identification requires examining the peel color, veins, and taste. If the peel is wrinkled, rough, yellow, and thick, with much white membrane inside, and tastes sweet with a hint of pungency, it is Rugan (Milky Citrus) peel, suitable only for tea infusion, not for medicine. If the peel is extremely thick and spongy, with very fine texture, yellow color, much membrane without veins, and tastes sweet with little pungency, it is Pomelo peel, which should not be taken cold. If the texture is fine, color is ruddy and thin, with many veins, and tastes bitter and pungent with an aromatic entry, it is genuine Huazhou Juhong. This type is precious for medicine. However, its nature is acidic and astringent, capable of damaging vital Qi. Although it resolves phlegm quickly, it breaks Qi and harms people, so it should not be used lightly. Recently, there is a type made from the peel of honey oranges produced in Tangxi Town, Renhe, called "Sweet Juhong." Its clear fragrance enters the lungs and awakens the spleen. Its phlegm-resolving efficacy is comparable to Huazhou production, but its nature is not harsh. Named "Xiangjinban," it is suitable for weak constitutions in the South.

*Bencao Chengya* states: Xi Shui in Wulin produces honey oranges, with dozens of varieties. The variety named "Jinqian Chuanxin" (Gold Coin Piercing Heart) is visually appealing, but inferior to "Foduqi" (Buddha's Belly Navel). Small in shape, bumpy peel, sweet and delicious, harvested at Frost Descent, possessing sufficient Qi and flavor. Stored tightly until spring, the peel is sliced, veins removed, sacs broken, and juice sucked. This can also invigorate the spirit and aid in breaking doubts during poetic composition.
