1. Harmonizing the stomach and alleviating nausea: Oranges are sour and cold in nature, entering the liver and stomach meridians. They harmonize the middle burner, stimulate appetite, and suppress nausea. They are particularly effective for vomiting caused by food stagnation, floating wind and pathogenic qi in the stomach, and liver-stomach heat stagnation.
2. Relieves chest congestion and disperses nodules. Oranges, with their cold nature, clear heat and descend rebellious qi. They excel at clearing heat from the lungs and chest. When heat accumulates in the lungs or external wind-heat invades, it scorches body fluids into phlegm. Phlegm-heat accumulates in the chest, obstructing qi movement, causing chest pain, coughing, wheezing, thick yellow phlegm, and in severe cases, coughing blood or foul-smelling phlegm, restlessness, fever,with a thick yellow coating on the tongue and a slippery, rapid pulse. Treatment with oranges is indicated to clear heat, eliminate phlegm, relieve chest congestion, resolve nodules, cool the blood, and stop bleeding, yielding remarkable efficacy. 3. Eliminating Goiters: Due to invasion by external pathogens, emotional distress, or constitutional weakness, qi stagnation occurs, causing body fluids to accumulate as phlegm. As stated in Danxi's Heart Method: "Phlegm follows the rise and fall of qi, permeating everywhere."Any mass in the upper, middle, or lower body is often phlegm. Thus, goiter formation inherently relates to phlegm stagnation.
When phlegm solidifies beside the Adam's apple, it forms a fleshy goiter. Symptoms include subcutaneous lumps beside the Adam's apple—non-red, non-hot, firm or cystic to the touch—with a thin greasy tongue coating and slippery pulse. Treatment should employ oranges to clear heat, resolve phlegm, relieve depression, and disperse masses.
4. Neutralizing fish and crab toxins: The sour and aromatic nature of oranges possesses antibacterial properties. They invigorate the spleen, harmonize the stomach, and alleviate nausea. For excessive alcohol consumption or dishes prepared with fish and crab, oranges serve as an excellent seasoning to detoxify and sober the mind. They enhance the palatability and flavor of dishes, imparting a fresh and savory taste.
5. Differentiated application: The orange fruit and orange seeds serve distinct purposes. The fruit flesh primarily stops vomiting, relieves chest oppression, eliminates goiters, and neutralizes toxins from fresh fish and crustaceans.Orange seeds, however, are more effective for treating hernias, various types of gonorrhea, and lower back pain. Externally applied, they can treat facial acne. Oranges primarily address liver and lung ailments, while orange seeds focus on kidney disorders.
