Overview

Xin Yi Qing Fei Yin — Magnolia Flower Drink to Clear Lung Heat — is a Ming-dynasty formula from Chen Shi-gong’s Wai Ke Zheng Zong (Orthodox Manual of External Medicine, 1617). It addresses the common modern presentation of chronic sinusitis from accumulated Lung Heat — the thick, yellow, foul-smelling, persistent nasal discharge that often follows repeated upper respiratory infections.

The formula combines aromatic, channel-opening herbs (Xin Yi, Bai Zhi) with Heat-clearing herbs (Huang Qin, Zhi Zi, Shi Gao, Sheng Ma) and Yin-nourishing herbs (Mai Men Dong, Bai He, Zhi Mu). This dual action — opening the nasal passages while clearing Heat and protecting Yin — addresses both the acute symptoms and the chronic Lung damage that perpetuates the pattern.

Xin Yi Qing Fei Yin is one of the most-used TCM formulas globally for chronic and recurrent sinusitis, nasal polyps and chronic rhinitis, particularly where conventional steroid sprays and antibiotics have given only partial relief.

I prescribe Xin Yi Qing Fei Yin as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan.

TCM pattern

Xin Yi Qing Fei Yin is prescribed for Lung Heat with chronic sinusitis:

• Chronic thick, yellow, sticky nasal discharge
• Foul-smelling discharge in some cases
• Loss of smell (anosmia) or reduced smell
• Frontal headache and facial pressure — particularly worse leaning forward
• Nasal congestion with difficulty breathing through the nose
• Postnasal drip with congestion in the throat
• Tickly cough from postnasal drip
• Dry mouth and slight thirst
• Mild fever or feeling of heat
• Slight halitosis
• Tongue — red, particularly at the tip; thin yellow coat
• Pulse — slightly rapid, possibly slippery

Key herbs

1. Xin Yi (Magnolia liliflora flower) — chief herb; opens the nasal passages; ascends to the head
2. Huang Qin (Scutellaria baicalensis) — clears Lung and upper-burner Heat
3. Zhi Zi (Gardenia jasminoides) — clears Triple Burner Heat
4. Shi Gao (gypsum) — clears Lung and Stomach Heat
5. Zhi Mu — clears Heat and nourishes Yin
6. Mai Men Dong — nourishes Lung Yin
7. Bai He (Lilium bulb) — moistens Lung Yin and clears empty Heat
8. Sheng Ma (Cimicifuga) — raises clear Yang and disperses Heat from the upper body
9. Pi Pa Ye (Eriobotrya japonica leaf) — descends Lung Qi and clears Heat
10. Gan Cao — harmonises

Comparisons with related formulas

• Cang Er Zi San — for Wind-Cold sinusitis with clear or white discharge; can be combined with Xin Yi Qing Fei Yin for mixed Cold-Heat presentations.
• Xin Yi San — for chronic sinusitis with Spleen Qi deficiency; less Heat-clearing, more about lifting Yang to open the nose.
• Yin Qiao San — for acute Wind-Heat upper respiratory infection without chronic Lung involvement.
• Bi Yan Wan — modern proprietary formula based on similar principles; for allergic rhinitis with mixed pattern.
• Sang Ju Yin — for acute Wind-Heat with cough; less focused on nose.

Modifications

• For pronounced foul-smelling discharge, add Yu Xing Cao and Pu Gong Ying
• For prominent facial pressure and headache, add Bai Zhi and Chuan Xiong
• For nasal polyps, add San Leng and E Zhu (with caution)
• For Damp-Heat overlay (heavy head, thick coat), add Cang Zhu and Huo Xiang
• For chronic recurrent pattern with Qi deficiency, combine with Yu Ping Feng San for prevention
• For Lung Yin deficiency overlay (dry mouth at night, peeled tongue), increase Mai Men Dong and add Sha Shen

Cautions

Not appropriate for Wind-Cold sinusitis with clear, thin, runny discharge — the cold herbs will trap the cold pathogen further. Use Cang Er Zi San or warming exterior formulas instead.

Not appropriate for Lung Qi or Spleen Qi deficiency without Heat — chronic sinusitis with thin clear discharge, fatigue and pale tongue calls for Bu Zhong Yi Qi Tang or Yu Ping Feng San.

Use cautiously in patients with weak digestion — the cold, draining herbs may damage Spleen Qi over long courses.

Use cautiously in pregnancy — contains Sheng Ma which can stimulate uterine contractions; modify with a qualified practitioner.

Acute sinusitis with high fever, severe headache, eye involvement, neurological symptoms or worsening despite treatment needs urgent medical assessment to exclude orbital cellulitis or intracranial complications.
