In Traditional Chinese Medicine (TCM), houpu magnolia flowers 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 houpu magnolia flowers are plants that are Warm in nature. This means that houpu magnolia flowers 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 houpu magnolia flowers can help restore a harmonious balance between Yin and Yang.
Houpu Magnolia flowers also taste Bitter. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Bitter ingredients like houpu magnolia flowers 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 houpu magnolia flowers are thought to target the Spleen and the Lung. In TCM the Spleen assists with digestion, blood coagulation and fluid metabolism in the body. In addition to performing respiration, the Lungs are thought to be a key part of the production chain for Qi and the body fluids that nourish the body.
