What is Blue Ginger (Galangal)?
Blue ginger is another name for galangal (Alpinia galanga), a rhizome from the Zingiberaceae family, which also includes ginger and turmeric. Originating in Central Asia, it has been used for centuries in Southeast Asian cuisine and traditional medicine. While its appearance is similar to regular ginger, its taste is markedly different, offering a sharper, more citrusy and peppery flavor. A common point of confusion arises because fresh ginger can sometimes develop a blue-gray tinge after being stored in a cold environment, but this is a different phenomenon entirely and does not affect the flavor significantly. The health benefits discussed in this article refer specifically to galangal.
Nutritional Profile and Health Benefits
While nutritional data can vary, galangal is valued for its rich concentration of bioactive compounds. It is considered a source of important nutrients and has long been used to treat various ailments. The primary health benefits come from its potent antioxidant and anti-inflammatory properties, supported by centuries of traditional use and emerging modern research.
Rich in Antioxidants
Galangal root is an excellent source of antioxidants, particularly polyphenols. These powerful plant compounds protect the body's cells from damage caused by free radicals, which are unstable molecules that can contribute to chronic diseases. The active compound galangin is a flavonoid found in galangal that has been extensively studied for its antioxidant activity. Antioxidant-rich diets are often linked with a lower risk of conditions such as heart disease and mental decline.
Potent Anti-inflammatory Properties
Inflammation is a natural bodily response, but chronic inflammation is associated with numerous health problems. Galangal contains phytochemicals, including HMP, that have shown potent anti-inflammatory effects in studies. This makes it a potential remedy for reducing pain and discomfort associated with inflammatory conditions. For instance, a study found that a combination of ginger and galangal extract helped reduce knee pain in people with osteoarthritis {Link: Healthline https://www.healthline.com/nutrition/galangal-root}.
Potential Anti-Cancer Effects
Several test-tube studies have investigated the potential of galangal compounds to fight certain types of cancer. Research has suggested that galangin may help kill cancer cells or prevent them from spreading {Link: Healthline https://www.healthline.com/nutrition/galangal-root}. Some studies specifically point to potential effects against breast, bile duct, colon, and liver cancer cells. However, these results come from test-tube and animal studies, and much more human research is needed.
May Boost Male Fertility
Emerging evidence suggests that galangal root may offer benefits for male fertility. One study found that a supplement containing galangal root and pomegranate fruit extract resulted in increased sperm motility {Link: Healthline https://www.healthline.com/nutrition/galangal-root}. Further human research is necessary.
Fights Infections and Microbes
Essential oils extracted from galangal root have shown antimicrobial properties in test-tube studies, fighting against bacteria such as E. coli, Staphylococcus aureus, and Salmonella Typhi {Link: Healthline https://www.healthline.com/nutrition/galangal-root}. The spice's protective effects may also help combat fungi and parasites. In addition, adding fresh galangal to food may help reduce the risk of infections from undercooked shellfish.
Supports Digestive Health
Traditionally, galangal has been used to alleviate various digestive issues. It is believed to aid digestion, reduce bloating and gas, and help with abdominal pain and constipation. Brewing galangal into a tea is a common method for soothing an upset stomach.

Infusing galangal slices in water with other ingredients like mint or cucumber also creates a refreshing drink.
Potential Risks and Considerations
While generally safe in culinary amounts, caution is advised with concentrated galangal supplements due to limited research on high-dose safety. Very high doses have shown serious side effects in animal studies. It's recommended to consult a healthcare professional before using galangal for medicinal purposes, especially if pregnant, breastfeeding, or on medication.
