Dried Ginger

Chinese: 干姜
Pinyin: Gan Jiang
Latin: Rhizoma Zingiberis

Botanical plate by Kodi .

Known in TCM as Gan Jiang (干姜), this acrid, hot herb enters the Spleen, Stomach, Heart, Lung, and Kidney. Traditionally, it warms the middle and dispels interior cold - Gan Jiang is a major herb for abdominal pain, vomiting, diarrhea, and weak digestion when cold impairs Spleen-Stomach function, most often applied for abdominal pain, diarrhea, and cough. Modern research has identified 6-Gingerol among its active constituents.

Part used: Rhizome

Also Known As

Zingiberis

Latin: Rhizoma Zingiberis | Pinyin: Gan Jiang | Chinese: 干姜

TCM Properties

Taste: acrid
Temperature: hot
Channels: Spleen, Stomach, Heart, Lung, Kidney

Traditional Use

Primary Actions

Warms the middle and dispels interior cold - Gan Jiang is a major herb for abdominal pain, vomiting, diarrhea, and weak digestion when cold impairs Spleen-Stomach function.
Rescues devastated Yang and restores the pulse - in severe deficiency-cold patterns it is combined with stronger agents such as Fu Zi to revive depleted Yang.
Warms the Lung and transforms thin mucus - traditional use extends to cold-phlegm cough, clear copious sputum, and chronic Lung cold.

Secondary Actions

Compared with fresh ginger, Gan Jiang is hotter, drier, and more focused on internal warming rather than on releasing the exterior.
Its processing concentrates a deeper middle-jiao and Yang-restoring action, which is why it appears in both digestive and collapse-rescue formulas.

Classic Formulas

Li Zhong Wan - classic formula for middle-jiao deficiency-cold with abdominal pain, diarrhea, and poor appetite in which Gan Jiang is the warming core.
Si Ni Tang - Gan Jiang works with Fu Zi and Zhi Gan Cao to rescue devastated Yang in severe cold-collapse patterns.
Xiao Qing Long Tang - includes Gan Jiang to warm the Lung and help transform cold fluids behind cough and wheezing.

Classical References

Traditional materia medica describe Gan Jiang as acrid and hot, entering the Spleen, Stomach, Heart, and Lung to warm the interior and restore Yang.
Its core identity is internal warming: middle-burner cold, devastated Yang, and cold-phlegm Lung patterns are the main classical uses.

Modern Research

Active Compounds

6-Gingerol - a major pungent phenolic associated more strongly with fresh ginger but still relevant to the dried rhizome chemistry
6-Shogaol - a dehydration product enriched by drying and heating, strongly associated with Gan Jiang's hotter pharmacologic profile
Zingerone and related phenolic compounds - supportive pungent constituents
Sesquiterpene volatile oils such as zingiberene - important aromatic compounds in ginger rhizome

Studied Effects

A 2024 review on quality markers and safety emphasized that drying and processing alter ginger chemistry and enrich shogaol-type constituents relevant to dried ginger's hotter medicinal profile (PMID 41508197).
Recent systematic review work found that ginger supplementation can improve several cardiovascular biomarkers, supporting broad anti-inflammatory and metabolic interest even though most studies are not Gan Jiang-specific (PMID 41195902).
Experimental work on dried ginger constituents demonstrated anti-inflammatory effects in lipopolysaccharide-stimulated macrophages and animal models, supporting the herb's broader modern pharmacologic relevance beyond digestive use (PMID 23935687).

Safety & Interactions

Contraindications

Excess heat or Yin deficiency heat patterns
Bleeding from blood heat
Dry cough from heat or fluid depletion

Cautions

Gan Jiang is much hotter than culinary ginger and should not be assumed to be interchangeable with casual food use.
Its drying warmth can aggravate thirst, constipation, or irritative heat symptoms if used without a true cold pattern.

Drug Interactions

Blood thinners or antiplatelet drugs - concentrated ginger preparations may increase bleeding tendency.
Diabetes medications - ginger extracts may modestly enhance glucose-lowering effects in some users.
