Ginger (生姜 Shēng Jiāng) is one of the most iconic foods in Traditional Chinese Medicine (TCM). Used for over 4,000 years as both food and remedy, it appears in the Shang Han Lun (伤寒论) by Zhang Zhongjing as a key ingredient in numerous therapeutic formulas. In Chinese dietetics, it is indispensable for expelling Cold, warming the Centre and relieving many ailments — including certain types of headaches.
Energetic Profile of Ginger in TCM
Thermal Nature and Flavour
Fresh Ginger (生姜 Shēng Jiāng) has a well-defined energetic profile:
- Nature: Warm (温 wēn)
- Flavour: Pungent (辛 xīn)
- Target meridians: Lung (肺 fèi), Spleen (脾 pí), Stomach (胃 wèi)
The pungent flavour has a dispersing and mobilising action. It promotes the circulation of Qi (气 qì), opens the pores and pushes pathogens outward. The warm nature heats the interior, which distinguishes it from frankly hot spices like cinnamon.
“Fresh Ginger warms the Stomach, expels superficial Cold and harmonises the Centre.” — Huangdi Neijing (黄帝内经)
Therapeutic Actions in TCM
| Action | Clinical application |
|---|---|
| Disperses Wind-Cold | Colds, chills, headaches from external invasion |
| Warms the Stomach | Nausea, vomiting, epigastric pain from Cold |
| Harmonises the Centre | Digestive disorders, morning sickness |
| Transforms Cold-Phlegm | Cough with white mucus, sensation of heaviness |
| Detoxifies | Neutralises certain toxic plants and foods |
Fresh Ginger vs Dried Ginger: A Crucial Distinction
In TCM, these two forms of the same food have radically different profiles:
Fresh Ginger (生姜 Shēng Jiāng)
- Nature: Warm
- Primary action: Disperses external Cold, body surface
- Ideal for: Onset of colds, nausea, Stomach harmonisation
Dried Ginger (干姜 Gān Jiāng)
- Nature: Hot
- Primary action: Warms internal Cold, body centre
- Ideal for: Cold-type diarrhoea, cold extremities, chronic abdominal pain
This distinction is fundamental for headaches in TCM: fresh ginger suits headaches from Wind-Cold invasion (acute pain, stiff neck), while dried ginger is indicated for Cold Stagnation in the Liver meridian (syndrome 6), a rare headache felt at the vertex.
Modern Nutritional Composition
| Nutrient | Per 100g fresh | Role |
|---|---|---|
| Gingerols | 1-3% | Anti-inflammatory, antiemetic |
| Shogaols | Traces (↑ with cooking) | Potent antioxidant |
| Vitamin B6 | 0.16 mg | Nervous metabolism |
| Manganese | 0.23 mg | Enzymatic antioxidant |
| Magnesium | 43 mg | Muscle relaxant, anti-migraine |
| Potassium | 415 mg | Electrolyte balance |
What Science Says (2020-2026)
Modern research validates many traditional uses of Ginger:
- Anti-inflammatory: Gingerols inhibit COX-1 and COX-2 enzymes, with a mechanism similar to NSAIDs, without the adverse gastrointestinal effects.
- Anti-migraine: A study published in Phytotherapy Research (2021) showed that 250 mg of ginger extract taken at the onset of a migraine attack was as effective as 50 mg of sumatriptan.
- Antiemetic: Proven efficacy (Level A) for pregnancy nausea and chemotherapy-induced nausea.
- Effects on Blood (血 xuè): Anti-platelet aggregation properties, favourable for circulation.

FAQ on Ginger in TCM
What is the thermal nature of ginger according to TCM? Fresh ginger (生姜 Shēng Jiāng) is Warm in nature with a Pungent flavour. It acts on the Lung, Spleen and Stomach meridians. Dried ginger (干姜 Gān Jiāng) is Hot in nature and acts deeply on internal Cold.
Can ginger relieve headaches? Yes, for headaches caused by Wind-Cold invasion (acute pain, stiff neck) or Blood Stagnation. It is contraindicated for headaches due to Liver Fire or Liver Yang Rising, as its warm nature could aggravate these Heat syndromes.
How much ginger should you consume daily according to TCM? For daily culinary use: 3 to 10 grams of fresh ginger. For acute therapeutic use (onset of cold): up to 15-20 grams in decoction. These doses are indicative and should be adapted to individual constitution.
Is ginger suitable for all constitution types? No. People with a Yang constitution (tendency towards heat, redness, thirst, constipation) should use ginger in moderation. It is particularly suited to Yin constitutions or people prone to Cold, cold extremities and slow digestion.
