In Gan Cao Gan Jiang Tang, Gan Jiang warms the Lungs and disperses Cold. Its primary function is to restore the Yang in chest. However, its acrid and hot nature can hurt the Lungs by depleting the source Qi. To overcome this problem, blast fried Ginger is recommended as its acrid and dispersing effect is reduced.
In Traditional Chinese Medicine (TCM), dried ginger are plants that belong to the 'Herbs that warm the Interior and/or expel Cold' category. Herbs in this category are used for Internal Cold with Qi Deficiency and/or Yang Deficiency. In the Yin and Yang system of thought Yang is Hot in nature. A deficiency of Yang will therefore lead to Internal Coldness since there will as a result be more Yin (Cold in nature) than Yang. In extreme cases this can lead to so-called 'Yang collapse' with convulsions or coma and these herbs are particularly indicated to treat such scenarios.
As suggested by its category dried ginger are plants that are Hot in nature. This means that dried ginger typically help people who have too much "Cold" in their body. Balance between Yin and Yang is a key health concept in TCM. Those who have too much 'Cold' in their body are said to either have a Yin Excess(because Yin is Cold in nature) or a Yang Deficiency (Yang is Hot in Nature). Depending on your condition dried ginger can help restore a harmonious balance between Yin and Yang.
Dried ginger also taste Pungent. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like dried ginger tend to promote the circulations of Qi and Body Fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such dried ginger are thought to target the Stomach, the Heart, the Kidney and the Lung. In TCM the Stomach is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine. In addition to regulating Blood flow, the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. The Kidneys do not only regulate the urinary system but also play a key role in the reproductive system and the growth and aging process of the body. In addition to performing respiration, the Lungs are thought in TCM to be a key part of the production chain for Qi and the Body Fluids that nourish the body.
