Generally oranges and honey are not used together for coughs because they treat two different kinds of coughs. Honey is generally moist and also sweet, and is particularly suitable for treating coughs with yin deficiency and lung dryness, mainly taking the role of moistening the lungs and supporting the effect when deficiency is evident. Oranges have the effect of regulating qi and are themselves phlegm-transforming, so they are generally used to treat phlegm-damp coughs. If you consume honey when you have a phlegm-damp cough, honey is too moist and will lead to bad phlegm clearance and easy phlegm production, so you can lightly add a little salt to the orange cough to neutralize the sweet and sour taste of the orange, because the lungs are very sensitive to the outside world and are easily stimulated by all kinds of tastes, such as sour, sweet, bitter, spicy and salty which is heavy, there will be problems. The sweet and sour taste of oranges is good, but after eating more of them, the sweet and sour taste will be too much, so a little light salt can be used to neutralize the phlegm of the oranges themselves, without causing an irritating cough because of the overpowering taste.
