"Green tea plus rock sugar" can effectively relieve the discomfort caused by pharyngitis. What is the medical basis for this collocation?

Traditional Chinese medicine believes that the occurrence of pharyngolaryngitis is mainly caused by deficiency of lung and kidney yin, excessive fire due to yin deficiency, rising of deficiency fire, or burning of the throat due to exogenous wind-heat and toxic heat. Green tea is cool, which has the functions of promoting fluid production, quenching thirst, clearing away heat and detoxifying; Crystal sugar is flat, which has the effects of tonifying the middle energizer, nourishing yin and moistening the lungs, relieving cough and resolving phlegm. In addition, rock sugar is often added to traditional Chinese medicine to elicit its efficacy. The combination of the two can give full play to the efficacy of green tea in clearing away heat and toxic materials, relieving sore throat and nourishing yin, moistening lung and promoting fluid production, thus improving dry and uncomfortable throat. In addition, among all sugars, rock sugar has the strongest nourishing effect, and its nourishing effect can improve human immunity and fundamentally enhance the human body's ability to fight pharyngitis. Therefore, patients with acute and chronic pharyngitis may wish to add some rock sugar when drinking green tea. But in order to avoid causing blood sugar to rise, diabetic patients should avoid taking it.

In addition to drinking rock sugar green tea regularly, patients with pharyngitis should also pay attention to the following points in their daily diet:

First, give priority to cool and peaceful food, and eat less or no irritating food such as garlic, pepper and liquor. Because these foods are easy to induce or aggravate mucosal congestion, this is tantamount to adding fuel to the throat.

Second, eat more fresh fruits and vegetables, such as pears, sugar cane, watermelons, radishes, loofahs, figs, water chestnuts, lotus roots, wax gourd, bananas, lilies and so on.

Third, we should moderately increase the intake of protein to improve human immunity. The level of human immunity is directly related to the recurrence of pharyngitis, so patients should appropriately increase the intake of high-quality protein such as fish, shrimp, meat and milk. When supplementing protein, we should pay attention to eating less isothermal food such as mutton and dog meat, otherwise it will easily aggravate the symptoms of throat discomfort.
