Introduction
Under normal circumstances, the throat refers to the pharynx. Pharyngeal itching may be caused by dry air, allergic reactions, excessive voice use, acute tonsillitis, acute laryngitis, or other reasons. If discomfort occurs, timely medical attention is recommended. It is also important to maintain humid indoor air and avoid staying in dry environments for prolonged periods. Use your voice appropriately, avoid speaking or singing loudly for extended periods, and take adequate rest.

Generally speaking, the throat refers to the pharynx. Pharyngeal itching may be caused by dry air, allergic reactions, excessive voice use, acute tonsillitis, acute laryngitis, and other factors. If discomfort occurs, timely medical consultation is recommended. A detailed explanation is as follows:

1. Dry Air

Excessively dry air can cause evaporation of moisture from the pharyngeal mucosa, resulting in dry mucous membranes and a sensation of pharyngeal itching. It is important to maintain indoor air humidity by using humidifiers and to drink plenty of water to keep the throat moist.

2. Allergic Reaction

Contact with allergens such as pollen, dust mites, or animal fur may trigger an allergic reaction in the pharyngeal mucosa, releasing inflammatory mediators like histamine, which may lead to itching. Avoid contact with allergens, maintain indoor cleanliness with regular cleaning, and wear a mask when going outdoors.

3. Excessive Voice Use

Speaking loudly or singing for prolonged periods can fatigue the vocal cords and pharyngeal muscles, potentially causing local congestion and inflammation, which may lead to itching. It is advisable to avoid overusing the voice and to rest appropriately. Drinking warm water after voice use can help relieve throat fatigue.

4. Acute Tonsillitis

Acute tonsillitis is often caused by bacterial infections, with streptococcal infection being common. Bacterial infection leads to swollen, congested tonsils accompanied by purulent inflammation. Inflammatory secretions can cause itching, often accompanied by symptoms such as sore throat and difficulty swallowing. Medications such as Roxithromycin Capsules, Golden Lotus Granules, and Pudilan Xiaoyan Tablets may be used under a doctor's guidance.

5. Acute Laryngitis

Acute laryngitis is commonly caused by viral or bacterial infections, but can also result from inhaling harmful gases or dust. Congestion and edema of the laryngeal mucosa caused by inflammation, along with inflammatory secretions, can lead to itching. Symptoms may also include hoarseness and coughing. Treatment may involve medications such as Amoxicillin Capsules, Ribavirin Capsules, and Prednisone Acetate Tablets, as prescribed by a physician.

Maintain indoor air humidity and avoid staying in dry environments for long periods. Use your voice appropriately, avoid speaking loudly or singing for extended periods, and take adequate rest breaks.

Ke Gan Granules can relieve symptoms of the common cold such as sore throat and cough, while Levofloxacin Hydrochloride Capsules are effective against susceptible bacteria. If a secondary bacterial infection develops during the later stages of a cold—manifesting as pus in the throat, yellow sputum, persistent fever—and bacterial infection is confirmed by examination, and if there is no drug allergy and liver and kidney functions are normal, combination therapy may be appropriate to simultaneously alleviate symptoms and combat the infection.

Is a dry nose due to lung fire or liver fire?
In general, dryness in the nose may be caused by excessive lung heat. Since the nose is considered the orifice of the lung, when lung heat is excessive, body fluids are depleted, leading to nasal dryness. This condition is often accompanied by symptoms such as sore and swollen throat, dry mouth, cough with little phlegm, or yellow and sticky sputum. Such cases are commonly associated with external contraction of heat pathogens or consumption of spicy foods. The accumulation of internal dry-heat in the lung channel impairs the nourishment of bodily fluids to the nasal area.
