In Traditional Chinese Medicine (TCM), coco-grass rhizomes are plants that belong to the 'Herbs that regulate Qi' category. Herbs in this category typically treat a TCM condition called 'Qi Stagnation'. Concretely it means that Qi is blocked in the body's Organs and Meridians, most typically the Stomach, Liver, and to a lesser extent, the Lungs. In modern medicine terms, Qi Stagnation often translates into psychological consequences such as depression, irritability or mood swings. It's also frequently associated with conditions such as premenstrual syndrome (PMS), menopausal symptoms, the development of breast swellings as well as various digestive disorders.
Furthermore coco-grass rhizomes are plants that are Neutral in nature. This means that coco-grass rhizomes typically don't affect the balance in your body. Balance between Yin and Yang is a key health concept in TCM. Eating too many "Hot" (Yang) ingredients can lead to an imbalance whereby one has a Yang Excess. The inverse is true as well: too many "Cold" (Yin) ingredients can lead to a Yin Excess. The Neutral nature of coco-grass rhizomes means that you don't have to worry about that!
Coco-grass rhizomes also taste Bitter, Pungent and Sweet. 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 coco-grass rhizomes tend to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. On the other hand Pungent ingredients 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. Lastly Sweet ingredients tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such coco-grass rhizomes are thought to target the Spleen, the Liver and the Sanjiao. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. The Liver on the other hand 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. The Triple Burner (Sanjiao) is a special concept in TCM with no corresponding organ in modern medicine. Its function is similar to a water wheel: Body Fluids, Qi and food are transported through the San Jiao and that very movement helps our metabolism.
