In Traditional Chinese Medicine (TCM), sweetflag rhizomes are plants that belong to the 'Herbs that open the Orifices' category. The functions of these herbs are much more platonic than the name implies. They're used to help treat conditions associated with central nervous system collapse, including strokes and coma.
Furthermore sweetflag rhizomes are plants that are Warm in nature. This means that sweetflag rhizomes tend to help people who have too much 'Cold' in their body, although with less effect than a plant that would be Hot in nature. 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 sweetflag rhizomes can help restore a harmonious balance between Yin and Yang.
Sweetflag rhizomes also taste Bitter. 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. Bitter ingredients like sweetflag rhizomes tend to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such sweetflag rhizomes are thought to target the Stomach, the Heart and the Liver. 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 Liver is often referred as the body's "general" because it is in charge of regulating the movements of Qi and the Body Fluids. It also takes a leading role in balancing our emotions.
