Health benefits of Galangal root

Galangal root is a low-calorie herb that has been in use in traditional medicines since ancient times to treat indigestion, cold, and ringworm infections (fungal dermatitis).

The rhizome composes several flavones like galangin which gives pungent punch to this root. Some of the other chemicals found are alpinin, kampferide, and 3-dioxy-4-methoxy flavone. Together, these compounds contribute antimicrobial, anti-inflammatory, anti-fungal, anti-tumor, and gastroprotective properties to galangal herb.

Selection and storage
Like ginger, galangal also can be grown in the backyards so that its fresh roots can be readily picked up for immediate use. Fresh galanga is widely available around the year in many South-East Asian regions. In the European and US markets, one may find fresh rhizomes in specialty stores selling Asian spices and herbs. Its dried powder (Laos) is also readily available here.
Buy fresh, light-yellow, healthy-looking roots about the size of a thumb. Fresh roots send a pleasant ginger-like aroma when you hold them close to the nostrils.
Fresh roots should be firm, juicy, and have a light-yellow peel.
Avoid broken, moist, slimy-surface, insect-afflicted roots. Also, avoid oversized, mature, fibrous, woody, shriveled roots as they tend to be less juicy and out of their prime.
Fresh galanga will keep for up to 2 weeks if stored in a cool, dry place. It can be stored in the refrigerator, but it must be wrapped in baking parchment to keep it moist.
Preparation and Culinary use
Wash the root in cold water, and mop-dry using a soft cloth. Peel the skin using a fine peeler. Galangal is quite tough than ginger, and therefore, it is usually thinly sliced (julienned) or cut into matchsticks for cooking. Because it is harder than ginger, it should be cooked for somewhat longer than ginger.
Galanga is an essential flavoring agent in Cantonese and Southeast Asian cooking, particularly in seafood and meat dishes. It is often pounded with shallots, lemongrass, garlic and chilies to make a spicy paste for dips and sauces/curries.
