Ju Luo (橘络; Jú Luò; Latin: Citri Reticulatae Retinervus; English: tangerine pith) is the fine network of fibrovascular tissue peeled from the inner rind of ripe Citrus reticulata fruit — the white threads most people pull off and throw away. It is neutral, sweet, and bitter, enters the Lung and Spleen channels, and its core actions are to regulate qi and unblock the collaterals, and to harmonize the stomach and transform phlegm. It is the gentlest of the qi-regulating herbs, moistening rather than drying. The usual amount is 3–6 g in a decoction. It does not need first, last, or wrapped decoction handling, and it is not a strong phlegm-breaker.
It is not Ju Hong. Red tangerine peel is warm, acrid, and bitter, and dries dampness and transforms phlegm much harder; Ju Luo is neutral and mild, and works by threading through blocked channels. It is not Chen Pi either — tangerine peel proper, which moves qi and harmonizes the stomach with more force. In pure deficiency with no stagnation, in marked damp-heat with a thick yellow coat, or in yin-dry cough, using it on your own is a poor match. Sharp fixed chest pain, or cough with blood, needs a clinic first. Pregnancy and nursing need care. Do not take it yourself for a long time.
It is used most often for three patterns:
Neutral, sweet, and bitter, it is not a daily "qi smoother" to keep sipping. Moving qi when there is no stagnation drains qi — its gentle edge still counts.
When qi stops in the chest and collaterals, or the spleen lets phlegm build, the chest feels tight, phlegm is hard to clear, and appetite drops. Ju Luo is neutral, sweet, and bitter. It moves, threads, and gently transforms, which is why it appears in Ju Hong Wan (橘红丸; Tangerine Peel Pill)–type formulas. It threads more than it blasts. In yin-dry cough, or with damp-heat and no stagnation, more makes it worse.
Ju Luo is not a catch-all chest-and-stomach herb. In pure deficiency, in marked damp-heat, or in yin-dry cough, using it alone is a poor match. Whether it belongs in a formula, and at what dose, should be decided by a licensed Chinese medicine practitioner after pattern diagnosis.
Identification & Quality Standard
Citri Reticulatae Fibrum
Botanical Origin
The dried vascular bundle from the peel of Citrus reticulata Blanco (Rutaceae).
Production Regions
Primarily produced in Sichuan, Zhejiang, Fujian, Guangdong.
Quality Requirements
Superior is long, white, clean, sweet.
Long thread-like, tangled into groups. Externally yellowish-white or tan, slightly translucent. Light, soft. Faint odor, slightly bitter taste.
Classic texts and trade experience value tangerine pith from several provinces of the south and east, but quality still depends on variety, harvest time, processing, and storage. Good material is a loose network, pale yellow to pale brown, light, soft, and pliable, with a faint fragrance and a slightly bitter taste. A honey-processed version is darker, with a honeyed aroma and a softer texture. The common look-alike is the pith of other citrus fruits, such as pomelo pith — coarser and looser than the fine tangerine web.
Sweet, Bitter; NeutralLiverLung
Every record stays within one circle — regulating qi and transforming phlegm — and none describes it as a fix for a named disease.
Views differ: some doctors saw Ju Luo as slightly clearing, fit for mild heat with qi-phlegm; others gave it a mild tonifying read, for a somewhat weak spleen with qi stagnation; a third group narrowed its scope — mainly the light qi-phlegm stagnation of the lung and spleen, not severe excess or deficiency; and some warned that in pure deficiency with no stagnation, even a gentle mover can add to damp retention. The through-line: pattern decides the use — it is not a universal regulator.
Traditional Functions
Moves qi and unblocks collaterals, resolves phlegm and stops cough.
(1) Traditional action: sorting out qi that is stuck in the channels so it runs smoothly again. (2) Typical patterns: mild chest or rib-side stuffiness and slight distension, phlegm that is hard to clear, or a mild local fullness in a limb — no sharp pain, no serious cough. (3) Usual pairings: Chen Pi (tangerine peel) and Zhi Ke (bitter orange) to strengthen the qi-sorting, and Ban Xia (pinellia) and Fu Ling (poria) to help transform the stuck phlegm. (4) Not for self-use: marked qi-and-blood stasis with fixed, sharp pain, or pure deficiency with no stuffiness at all (long-standing fatigue without fullness).
(1) Traditional action: harmonizing the spleen-stomach and transforming the phlegm that forms when digestion stalls. (2) Typical patterns: mild stomach fullness, poor appetite, a little sticky phlegm that is hard to cough up, and a greasy-but-not-thick tongue coat. (3) Usual pairings: Bai Zhu (atractylodes) and Sha Ren (amomum fruit) to harmonize the stomach, with Jie Geng (platycodon) and Xing Ren (apricot kernel) to open the lung and help the phlegm out. (4) Not for self-use: marked spleen-stomach damp-heat (bitter mouth, thick yellow greasy coat), or yin-dry cough (dry cough without phlegm, dry mouth).
Ju Luo pairs classically with Chen Pi. Ju Luo threads the qi stuck in the collaterals; Chen Pi regulates qi and harmonizes the stomach. Ju Luo's threading helps Chen Pi reach the chest, rib, and stomach qi; Chen Pi's stomach-harmonizing helps Ju Luo transform stomach phlegm — together for mild chest and rib fullness, stomach discomfort, and phlegm that will not clear. This pair belongs to a practitioner's pattern diagnosis, not self-pairing.
Modern research offers useful context, but Traditional Chinese Medicine prescribes on whole-pattern diagnosis rather than isolated compounds.
Detected in the pith are flavonoids — hesperidin and naringin — along with small amounts of volatile oil, pectin, and lignin. In vitro, the flavonoids showed some antioxidant activity; in animal experiments, the extract showed a possible effect on airway mucus secretion. There is not yet enough human research to confirm any effect on people.
Both lines are still at the experimental stage; human studies are needed before any practical claim can be made.
Nature and flavor: Ju Luo is neutral, sweet, and bitter — even, neither cold nor hot; Ju Hong is warm, acrid, and bitter, with a warm-dry edge that warms cold phlegm. Focus: Ju Luo leads with threading the collaterals — it eases mild chest, rib, and local stuffiness, transforming phlegm gently; Ju Hong leads with drying dampness and transforming phlegm — it works harder on spleen dampness and copious phlegmy cough, and moves qi faster. Tendency: Ju Luo spreads — a light upward-and-outward push that does not waste qi, with a channel-threading side; Ju Hong scatters — a quicker push through spleen-stomach qi, with a warm-dry side that can waste fluids, wrong for yin deficiency. Best fit: Ju Luo for mild chest and rib stuffiness with hard-to-clear phlegm and a thin greasy coat, without clear cold or heat; Ju Hong for stomach fullness, copious white sticky phlegm, and a thick greasy coat. Who should avoid: Ju Luo is wrong for pure deficiency with no stagnation, marked damp-heat, and yin-dry cough; Ju Hong is wrong for yin-dry cough, lung-heat cough, and people with heat and a dry mouth. Where you meet them: Ju Hong in stronger spleen-damp formulas and cold-phlegm remedies; Ju Luo in light teas and small formulas for everyday mild discomfort.
In short, Ju Luo leans to gentle channel-threading for mild qi-phlegm stagnation; Ju Hong leans to warm-drying and transforming phlegm for spleen dampness. Both can appear in qi-regulating care — but they are not stand-ins for each other.
Role of this herb: in Ju Hong Wan (Tangerine Peel Pill), Ju Luo is an assistant herb — not one of the leads — helping the main herbs thread stuck qi through the collaterals and supporting phlegm transformation. The leads are Ju Hong and Chen Pi (regulating qi and transforming phlegm), with Ban Xia and Fu Ling (fortifying the spleen and drying dampness); Ju Luo's job is to let qi move more smoothly through the channels. It is not meant to be used alone — its power is too light to carry the qi-regulating, phlegm-transforming load by itself. Traditional focus: lung-spleen qi stagnation with phlegm-damp — cough with copious phlegm, chest and diaphragm fullness, poor appetite. Modern note: any modern use belongs to a licensed practitioner after diagnosis — never self-apply by name.
Role of this herb: in a modified Xiao Yao San (Free-and-Easy Powder) with Ju Luo added, Ju Luo is an assistant, helping Chai Hu (bupleurum) and Dang Gui (Chinese angelica root) course the liver qi and thread the qi stuck in the collaterals, while harmonizing the stomach. Chai Hu and Dang Gui are the leads — coursing liver qi, nourishing blood, and fortifying the spleen — with Bai Zhu and Fu Ling supporting the spleen and stomach. Ju Luo's addition helps liver qi disperse more gently, so the qi movers do not have to push so hard. Traditional focus: liver qi stagnation with spleen disharmony — chest and rib pain, low mood, reduced appetite. Modern note: professional diagnosis first; never self-apply from symptoms.
A formula is a coordinated team. Take Ju Hong Wan: its qi-regulating, phlegm-transforming effect comes from Ju Hong, Ban Xia, Fu Ling, and the rest working together — Ju Luo alone cannot reach that. Doses and pairings are designed as a whole, and a herb that helps inside a formula does not automatically work the same way alone. Do not self-formulate from web articles.
Ju Luo 3 g with Chen Pi 2 g, steeped in boiling water for 5 minutes. Fit: mild chest and rib stuffiness, a little hard-to-clear phlegm, or poor appetite — an autumn-winter daily routine, 2–3 cups a week. Not for: marked damp-heat or yin-dry cough; pregnancy — consult a practitioner first.
Raw Ju Luo is light and soft with a faint smell, made for daily use; a honey-processed version is softer with a honeyed aroma, for people with a weaker spleen. No first, last, or wrapped handling is needed — the fine network spreads easily in the pot, so it can go in with the other ingredients and decoct for about 15–20 minutes. Different forms cannot be converted directly: the food-use amount (about 3 g) is not a medical dose.
The classic range is 3–6 g for mild discomfort; food-use amounts are about 2–3 g. Not for long continuous use — keep each course to about 7 days, then pause. Pregnancy, children, and the elderly: consult a practitioner or pharmacist before use.
Marked spleen-stomach damp-heat (bitter mouth, thick yellow greasy coat, sticky stools) — the herb can add to the damp-heat; yin-dry cough (dry cough without phlegm, dry mouth, night sweats) — even a gentle mover can waste fluids; pregnancy and nursing — no safety evidence, consult first; children and the elderly — different tolerance, guidance only; liver or kidney impairment — cautious use; allergy to citrus plants — possible reaction, avoid.
No clear interaction with other herbs is recorded, but anyone on anticoagulants, blood-pressure, blood-sugar, or sedative medicines should ask a doctor or pharmacist. If you take other medicines, leave 1–2 hours between them and Ju Luo so absorption is not disturbed. No blanket "food clash" with ordinary foods is established, but herbs can interact with specific medicines.
At normal doses, reactions are rare. Overuse can bring mild stomach discomfort or nausea. Stop and seek care at once for marked discomfort, an allergic reaction (rash, itching), persistent vomiting, trouble breathing, confusion, or a rapid worsening of symptoms.
