Traditional Chinese Uses
Gao Liang Jiang (lesser galangal rhizome) is a hot, pungent herb used to warm the Stomach and Spleen and dispel cold, addressing acute cold-type stomach pain, vomiting, and diarrhea with great effectiveness. It is one of the most specifically warming herbs for the Stomach channel — directly targeting cold lodged in the Stomach — and is used when chilling foods or cold weather have caused sudden severe gastric pain, nausea, or digestive collapse. Combined with dried ginger, it forms classical formulas for acute cold in the Stomach.

Botanical Description
Alpinia officinarum, lesser galangal or Gao Liang Jiang, is a tufted, rhizomatous perennial herb in the Zingiberaceae, native to southern China (especially Hainan and Guangdong) and now also cultivated in adjacent parts of Southeast Asia. The plant grows from a horizontal, cylindrical, branched rhizome 1 to 2 cm thick, reddish-brown on the outside with prominent annular leaf-scars and pale orange-yellow, intensely aromatic flesh on cutting. From the rhizome arise tufted leafy pseudostems 30 to 110 cm tall, each bearing two ranks of narrow, linear-lanceolate leaves 15 to 30 cm long and 1.2 to 2.5 cm wide, with a long-acuminate tip and glabrous, glossy green surfaces. The terminal inflorescence is a slender raceme 6 to 10 cm long bearing few flowers; each is white with conspicuous red veins on the labellum and pink stamen. The fruit is a small, globose, red capsule about 1 cm across. The dried rhizome is the medicinal drug, pungent and aromatic with cineole and galangol.
Active Constituents
Galangin
Flavonol (3,5,7-trihydroxyflavone)Concentration: The principal flavonoid of the rhizome and the compound most often used as its analytical marker
Carries most of the antioxidant and anti-inflammatory activity attributed to the rhizome in preclinical work, and has been studied extensively for antimicrobial and antiproliferative effects in cell culture. Human pharmacokinetic and efficacy data on galangin from Alpinia officinarum are essentially absent.
1,7-Diphenyl-5-hydroxy-3-heptanone and related linear diarylheptanoids
DiarylheptanoidThe chemically distinctive class of the rhizome, structurally related to the curcuminoids of turmeric. Members of this group have shown antibacterial, cytotoxic and neuroprotective activity in isolated-compound assays, and the diarylheptanoid profile is what separates Alpinia officinarum from other members of the genus.
Kaempferide and galangin 3-methyl ether
Methylated flavonolsMethylated flavonol congeners of galangin present in the rhizome, contributing to the flavonoid fingerprint used for chromatographic identity testing.
1,8-Cineole and alpha-pinene
Monoterpenes (essential oil)The main volatiles of the rhizome oil. They account for the aromatic pungency of the drug and plausibly for its carminative effect on the stomach, which is its principal traditional indication.
⚠ Drug Interactions
Alpinia galanga (greater galangal, Da Gao Liang Jiang; its fruit is Hong Dou Kou)
Both rhizomes are sold in the West simply as galangal, and Alpinia galanga is much the more widely traded of the two as a culinary root. They are not chemically equivalent: Alpinia officinarum is characterised by galangin and linear diarylheptanoids, while Alpinia galanga is characterised by phenylpropanoid acetates. Most of the small human trial literature on the genus has used Alpinia galanga preparations, so it should not be read across to Gao Liang Jiang. Substituting one for the other is a loss of identity rather than a poisoning risk, but it means the material in the pot is not the drug the prescription named.
Clinical note: Order by binomial and check the certificate of analysis for galangin. Do not cite Alpinia galanga clinical data in support of Gao Liang Jiang, and do not accept culinary galangal from a food supplier as pharmacopoeial Rhizoma Alpiniae Officinarum.
Drugs cleared by cytochrome P450 with narrow therapeutic indices
Galangin is a flavonol, and flavonols as a class interact with cytochrome P450 and phase II conjugating enzymes in vitro. No human pharmacokinetic interaction study of Alpinia officinarum or of galangin has been published, and the reviews of this drug report no clinical interaction data at all. This entry records the absence of evidence rather than a demonstrated effect.
Clinical note: No specific action is warranted at culinary or customary decoction doses. Concentrated galangin extracts and long courses alongside narrow-index drugs are simply uncharacterised territory.
Antihyperglycaemic drugs
Extracts and isolated constituents of Alpinia officinarum have shown hypoglycaemic and insulin-sensitising effects in rodent models, as summarised in the pharmacological reviews of the species. Whether that translates into any additive effect with oral hypoglycaemics or insulin in humans has not been tested.
Clinical note: If a diabetic patient takes Gao Liang Jiang regularly at more than culinary quantities, it is reasonable to keep an eye on glucose readings during the first weeks, without expecting a change.

Clinical Studies
A review on the ethnomedicinal uses, phytochemistry and pharmacology of Alpinia officinarum Hance
Collects the ethnomedicinal, phytochemical and pharmacological literature on Alpinia officinarum. The pharmacology it summarises is preclinical throughout; the review identifies no controlled clinical trial of the rhizome, which is the honest state of the evidence for this drug.
Alpinia officinarum Hance: a comprehensive review of traditional uses, phytochemistry, pharmacokinetic and pharmacology
An updated synthesis covering traditional use, constituents, pharmacokinetics and reported activities. It confirms galangin and the diarylheptanoids as the characteristic chemistry and again finds the pharmacology to rest on animal and cell studies rather than on patients.
New diarylheptanoids from the rhizome of Alpinia officinarum Hance
Isolates and characterises previously undescribed diarylheptanoids from the rhizome, extending the known chemistry of the drug.
Three new antibacterial active diarylheptanoids from Alpinia officinarum
Reports antibacterial activity for three newly isolated diarylheptanoids in culture. Isolated-compound in vitro activity, with no bearing on the clinical use of the decocted rhizome.
Diarylheptanoids from the rhizome of Alpinia officinarum Hance.
The early structural work that established diarylheptanoids as a defining constituent class of the Alpinia officinarum rhizome.
New cytotoxic diarylheptanoids from the rhizomes of Alpinia officinarum Hance
Describes further diarylheptanoids from the rhizome with cytotoxic activity against tumour cell lines in culture.
