Notes

1. Because this herb moves Qi generally while specifically sending it downward, it is used for many kinds of nausea and vomiting.
2. As a key Qi level herb of both the Spleen and Lung channels, it is particularly valuable for disorders affecting both channels.
3. Added to tonic herbs, it keeps their cloying nature from producing Stagnation.
4. According to one source, it also tonifies the Spleen.
5. It is aged tangerine peel, and the older it is, the better.
6. It is indicated for excessive Phlegm and/or a stifling feeling in the chest, along with belching.
7. While the peel sends Qi downward to promote the movement of Phlegm, the flesh of the fruit generates Phlegm and clusters Qi.
8. Ju Pi moves Qi, disperses knots, and stops pain, and is used for hernia pain and testicular pain.
9. Ju Luo De-obstructs the collaterals and transforms Phlegm, and is used for Phlegm congestion and cough accompanied by chest and rib pain.
10. Compared with Per. Citri Reticulatae Viride Qing Pi, Chen Pi is more harmonious and tends to enter the Qi level of the Spleen and Lungs. Its actions are more vertical, so it is used for coughing and vomiting. Qing Pi scatters and unblocks in a relatively harsh way and is mainly used to break up Qi Stagnation. Its actions are mainly horizontal, so it is used more for pain.
11. In Dry-fried Aged Tangerine Peel Chao Chen Pi, the acrid nature is moderated while the warm, strengthening quality is enhanced.
12. Charred Aged Tangerine Peel Chen Pi Tan no longer regulates Qi; instead it reduces Food Stagnation, harmonizes the Stomach and stops bleeding.

14. Tangerine Pip, Semen Citri Reticulatae Ju He, is bitter and neutral; it promotes the movement of Qi, dissipates clumps and stops pain.

Today it is commonly used for bulging disorders such as hernias, and it is also applied internally and externally for acute mastitis.
15. Tangerine Pith, Vascular Citri Reticulatae Ju Luo, is sweet, bitter and neutral; it opens the flow in the channels and collaterals, promotes the movement of Qi, and transforms Phlegm. It treats Phlegm stagnating in the channels and collaterals with cough and chest and flank pain, and is particularly effective for distention in the vessels of the Lung caused by rebellion of protective Qi.
16. Tangerine Leaf, Folium Citri Reticulatae Ju Ye, is acrid, bitter and neutral. It dredges the Liver and promotes the proper movement of Qi, while reducing swellings and dispersing clumps. Indications include hypochondriac pain, breast abscesses, breast lumps and abdominal masses. The dosage is 6-9g.
17. Exocarpium Citri Reticulatae Rubrum Ju Hong is acrid, bitter and warm, entering the Lung and Stomach. It is more drying and aromatic than Chen Pi, but harmonizes the Middle and regulates the Spleen and Stomach less effectively. Its main uses are vomiting, belching and Phlegm-Damp coughs. The dosage is 3-9g.
18. Pomelo Flavedo (Huazho Pomelo Rind) Exocarpium Citri Grandis Rubrum Hua Ju Hong is acrid, bitter and warm, entering the Lung, Spleen and Stomach. It regulates the Qi, expands the chest, dries Dampness, transforms Phlegm and reduces Food Stagnation.

It is not indicated for patients with Qi Deficiency or with dry Phlegm and Yin Deficiency. The dosage is 3-6g.
19. Dui Yao pair with He Zi: for a hoarse voice or loss of voice, and chronic cough with loss of voice and Phlegm in the throat.
