Galangal gives a fresh and full-of-gusto feel to any Thai or Asian dish. This ginger look-alike (and close cousin) has tremendous therapeutic importance in Chinese and traditional Asian medicine. The phytochemicals present in it make galangal a strong antioxidant, analgesic, anti-inflammatory, and anticancer agent.

Read on to know the what, why, and how of galangal, in-depth!

What Is Galangal?

Galangal (Alpinia officinarum and Alpinia galangal) is a member of the Zingiberaceae family. This perennial herb is indigenous to South-east China and Indonesia and grows in the plains of West Bengal, Assam, and Eastern Himalayas in India (1).

Ayurveda and traditional Chinese and European medicine have used different parts of galangal to treat colds, stomach ache, inflammation, diabetes, ulcers, nausea, diarrhea, eczema, and various acute and chronic conditions (1).

The seed of galangal is used as a mouth freshener, dental cleanser, digestive aid, and laxative. The flowers and tender shoots are used as a spice or vegetable. The root or rhizome is used as a spice and source of essential oil (like ginger).

As it looks, tastes, and feels like ginger, galangal is also called the ‘mild ginger’ (Liang-tiang) in Chinese. Like ginger, galangal has flavonoids, polyphenols, terpenes, and essential oils (2).

Want to know how these bioactive components of galangal work together on your body systems? Read the next section to find the answers!

How Is Galangal Beneficial For Your Body?

1. Has Antidiabetic Properties

According to a 2015 study, methanolic extracts of galangal showed antidiabetic potential. Aerial parts of galangal can stimulate the regeneration of insulin-secreting ß-cells in the pancreas. Administering galangal extracts to diabetic rats lowered cholesterol and triglyceride levels, improving lipid metabolism and preventing diabetic complications (3).

Galangal extract was found to inhibit carbohydrate metabolism, minimizing the postprandial blood glucose spikes. The glucose-controlling activity was on par with synthetic antidiabetic drugs (4).

Due to its antioxidant activity, this herbal medicine can protect your liver and pancreas from oxidative stress and damage. The polyphenols, alkaloids, triterpenes, steroids, and carbohydrates in galangal are proposed to be responsible for this activity (3).

2. Might Possess Antiproliferative Effects

Aqueous extract of Alpinia galangal can inhibit the proliferation of human gastric tumor cell lines. The galangal rhizome (root) contains two cytotoxic compounds against cancer cells, namely, acetoxychavicolacetate and p-coumaryl alcohol-O-methyl ether (5).

Galangal extracts showed anticancer effects on melanoma (skin) cells, preventing skin cancer too (5).

The cytotoxic compounds in this Chinese herb can induce glutathione-S-transferase (GST) activity in the liver cells. GSTs eliminate mutagenic compounds and free radicals, thus preventing cancerous changes from occurring (6).

3. Can Aid The Treatment Of Arthritis And Other Inflammatory Diseases

Galangal rhizomes have flavonoids, tannins, saponins, glycosides, and several phenolic compounds. These phytochemicals, galangin particularly, showed potent anti-inflammatory and analgesic effects in animal studies (7).

Galangin down-regulates the expression of genes that produce pro-inflammatory compounds like cytokines and interleukins (8).

As galangal extracts may inhibit COX-1 and 2 and lipoxygenase pathways, they could be used to manage arthritis, edema, inflammatory bowel disease, and other inflammatory disorders (9), (10).

4. Has Antimicrobial Properties

Researchers claim that the essential oils from dried and fresh galangal rhizomes can eliminate bacteria, yeast, fungi, and parasites. Terpinen-4-ol, one of the monoterpenes in the essential oil derived from fresh galangal rhizome possesses antimicrobial activity against Trichophyton mentagrophytes (11).

Acetoxychavicol acetate (ACA), a compound isolated from the extract of dried rhizomes, is active against certain dermatophyte (skin-infesting) bacterial species. Among turmeric and ginger, galangal has the most potent inhibitory effect against Staphylococcus aureus (10).

Alpinia galanga is also a broad-spectrum fungicide. It can inhibit fungi and yeast, such as Aspergillus niger, Trichophyton longifusus, Colletotrichum musae, Fusarium oxysporum, Trichophyton mentagrophytes, Trichophyton rubrum, and Rhizopus stolonifer (12).

5. Can Boost Sperm Count And Motility

Unlike other aphrodisiacs or fertility supplements, galangal is safe and non-toxic. Rat studies showed that 56 days of treatment with galangal rhizome improved spermatogenesis and related parameters (13).

The sperm count and mobility increased after this treatment. The increase in sperm density and motility in cauda epididymis (the storage site for mature sperm) can affect fertilization (13).

Galangal influences the protein production via expression of related genes involved in spermatogenesis. It could, hence, be used in drugs to promote male fertility (13). Clinical data can elucidate the safety of this herbal extract in the future.

In the earlier sections, we briefly discussed how a powerful phytochemical profile gives galangal its unique health benefits.

Let’s look at those phytochemicals in detail. Scroll down!

Biochemical Composition Of Galangal

Most sub-species of galangal have good amounts of flavonoids. Galangin, alpinin, kaempferol, kaempferide, pinene, pineol, chavicol, methyl cinnamate, hydroxycinnamaldehyde, isorhamnetin, camphene, myrcene, p-cymene, borneol, terpineol, 4-terpineol, fenchyl acetate, bornyl acetate, humulene, and zerumbone were a few identified ones (14).

The leaf oil contains myrcene, ocimene, pinene, borneol, caryophyIIene, and bisabolene. The essential oil from galangal flower has a-pinene, sabinene, limonene, phellandrene, 1,8-cineole, linalool, terpinen-4-ol, a-terpineol, methyleugenol, patchoulene, caratol, a-farnesene, nerolidol, bisabolol and benzyl benzoate (14).

The galangal fruits contain acetyleugenol acetate and 1′-acetoxychavicol acetate. The seed contains caryophyllene oxide, caryophyllenol, pentadecane, 7-heptadecane, and fatty acid methyl esters (13).

It is because of these terpinols and esters in the essential oils that galangal is used as a perfume or freshener in India and the Middle Eastern countries.

As a bonus, each serving of galangal gives you 45 calories and 2 g of dietary fiber. It is also a natural source of sodium, iron, vitamins A and C (almost like ginger).

That, indeed, is a power-packed biochemical profile! No wonder the Chinese obsessed over galangal and made many recipes with it.

Yes, that’s right. Several cuisines incorporate galangal in their delicacies. Here’s a quick and simple recipe for you.

How do you store galangal?

Wrap the galangal root in a damp, clean cloth. Then, wrap it in a plastic bag. You can store galangal this way in the fridge for a long time. The root retains the moisture from the cloth and stays fresh too.
If it is for extended storage, you might have to change the damp cloth to prevent fungal infestation.
