Ginger (Sheng Jiang)

Overview

Ginger (Zingiber officinale) is one of the most widely used roots in Traditional Chinese Medicine, where it is known as Sheng Jiang (fresh ginger) and Gan Jiang (dried ginger). Fresh and dried ginger are considered different herbs with different strengths: fresh ginger is warmer and dispersing, often used for early-stage colds, nausea and digestive upset, while dried ginger is hotter and deeply warming, used for cold in the middle burner, diarrhea and cough with clear watery phlegm.

Traditional Uses in TCM

• Digestive support: ginger relieves nausea, bloating and poor appetite, and is a classic remedy for "cold in the stomach".
• Early-stage colds: fresh ginger tea with brown sugar and scallion is the standard home formula at the first sign of chills and stiff neck.
• Nausea and vomiting: from morning sickness to motion sickness, ginger is one of the best-studied natural anti-nausea agents.
• Warming the body: dried ginger is used in formulas for people who feel cold all the time, with pale complexion and loose stools.

How to Use

Fresh ginger can be sliced and simmered in water for 10 minutes, added to soups and stir-fries, or juiced with lemon and honey. A typical daily amount is 3 to 10 grams of fresh root or 2 to 5 grams of dried root. Dried ginger powder is usually taken in capsules or mixed into warm water. For colds, a classic drink is 5 slices of fresh ginger, 3 scallion whites and a spoon of brown sugar simmered for 10 minutes, drunk hot before bed.

Safety and Cautions

Ginger is very safe in food amounts. In concentrated doses it can cause heartburn or stomach irritation in sensitive people. Because ginger mildly thins the blood, people taking anticoagulant medication such as warfarin, or those scheduled for surgery, should consult a doctor before taking large amounts. High doses are not recommended during pregnancy without professional guidance, although normal culinary use is considered safe. In TCM terms, ginger is contraindicated for patterns of true heat, such as high fever with red face and dry mouth.

Related Concepts

Ginger also acts as a guiding herb (使者药) in many classical formulas, moderating the stomach-irritating effects of other herbs. It pairs classically with jujube dates (Da Zao) in decoctions to harmonize the middle burner, a combination found in dozens of formulas from the Shang Han Lun.
