Green Tangerine Peel (Qing Pi) Function and Efficacy Recorded in TCM
Qingpi is a very important and commonly used qi regulating medicine in traditional Chinese medicine. It is the skin of dried young or immature fruits of the Rutaceae plant orange and its cultivated varieties. Compared with aged tangerine peel (mature fruit skin), green peel has stronger medicinal properties, stronger ability to promote and break qi, and its active site is biased towards the middle and lower parts.

Its core function is to “soothe the liver, break down qi, and eliminate accumulation and stagnation”.

Below is a detailed explanation of the role and application of Qingpi in traditional Chinese medicine:

1.Soothing the liver and breaking the qi
This is the core function of Qingpi. It is good at regulating the qi of the liver and gallbladder meridians, and has a strong dredging effect on qi stagnation caused by emotional depression and anger (i.e. “liver qi stagnation”).

Pain in the ribs and breasts: The liver meridian runs along both sides and spreads to the chest and ribs. Stagnation of liver qi can cause pain and swelling in the rib area. Qingpi is an essential medicine for treating such symptoms. For premenstrual breast swelling and pain, as well as breast hyperplasia (mastitis) in women, it is often used together with medicines such as Chaihu, Yujin, and Xiangfu.

Hernia pain: Traditional Chinese medicine believes that hernia is related to liver meridian qi stagnation and cold coagulation. Qingpi can soothe the liver, promote qi circulation, disperse nodules and relieve pain, and is a commonly used medicine for treating hernia. It is often used in conjunction with black medicine, fennel, and wood fragrance, such as the classic formula “Tiantai Wuyao San”.

Symptomatic accumulation: For liver and spleen enlargement, abdominal masses, and other conditions caused by qi stagnation and blood stasis over time, Qingpi, with its “qi breaking” power, can disperse qi and cause nodules. It is often used in conjunction with blood breaking drugs such as Sanjing and Curcuma.

2. Eliminate accumulation and stagnation
Qingpi has a strong and pungent odor, and has a strong digestive and stasis inducing effect, especially good at breaking and releasing gastrointestinal gas accumulation.

Stagnation of food and qi, bloating and pain in the epigastric region: Used for irregular eating, stagnant food in the epigastric region, leading to bloating, pain, belching, acid reflux, and lack of appetite. Its ability to move qi is stronger than that of dried tangerine peel, and it is often used together with digestive medicines such as hawthorn, malt, and Shenqu.

Full abdominal distension, constipation or urgency: For abdominal distension, constipation with severe obstruction of qi, or urgency and heaviness in dysentery, Qingpi can promote qi conduction and relieve symptoms.

Modern Pharmacological Effects of Green Tangerine Peel (Qing Pi)
The modern pharmacological research on Qingpi provides strong scientific basis for its traditional Chinese medicine efficacy. Its pharmacological activity mainly comes from volatile oils (such as limonene), flavonoids (such as hesperidin), alkaloids, and other components.

The following are the main modern pharmacological effects of Qingpi:

1. Effects on the digestive system
This is the most prominent and distinctive pharmacological field of Qingpi, which directly corresponds to its efficacy of “reducing accumulation and resolving stagnation”.

Regulating gastrointestinal motility (bidirectional regulation):
Spasmodic effect: Qingpi can antagonize gastrointestinal smooth muscle spasms caused by acetylcholine, histamine, etc., thereby relieving abdominal pain. This is the basis for its treatment of “qi stagnation” pain.

Excitatory effect: For the relaxed or functionally inhibited gastrointestinal tract, Qingpi can also excite the smooth muscles of the gastrointestinal tract, enhance intestinal peristalsis, promote exhaust and content propulsion. This explains its efficacy in treating food accumulation, bloating, and constipation.

Gallbladder and liver protection:
It can promote bile secretion, relax the sphincter muscle of Oedipus, facilitate bile excretion, and is used to treat biliary colic, gallstones, etc.

It has a protective effect on chemical liver injury.

Anti gastric ulcer: It has a preventive and therapeutic effect on experimental gastric ulcers by inhibiting gastric acid secretion and protecting the gastric mucosa.

2. Effects on the respiratory system
Dispelling phlegm and relieving asthma:

Its volatile oil components have a stimulating and expectorant effect, making it easy to cough up phlegm.

It can counteract bronchospasm caused by histamine and have a bronchodilator effect. This is similar to the effect of dried tangerine peel in “drying dampness and resolving phlegm”, but with stronger strength.

3. Effects on the cardiovascular system
Boosting and strengthening heart:

The injection of Qingpi has a significant and rapid pressor effect, and its mechanism is to excite alpha adrenergic receptors.

Can enhance myocardial contractility and improve blood circulation. This may have potential value in traditional Chinese medicine emergency treatment, but the effect of oral preparations is not significant.

4. Antioxidant and anti-inflammatory properties
The flavonoids in Qingpi have significant antioxidant activity, which can eliminate free radicals and alleviate oxidative stress damage.

By inhibiting the release of inflammatory factors and exerting anti-inflammatory effects, this is consistent with the traditional record of treating inflammation such as “carbuncles”.

5. Other functions
Antibacterial and antiviral: It has inhibitory effects on various bacteria and fungi.

Regulating uterine smooth muscle: It has an excitatory effect on uterine smooth muscle, which provides a pharmacological explanation for its caution in pregnant women.
