Introduction
In general, when symptoms of a sore throat are mild, a small amount of vinegar may be used as a cooking seasoning. However, direct consumption of vinegar or its use during severe symptoms is not recommended. When experiencing throat inflammation, the diet should consist of mild and moist foods. Drink plenty of warm water or rinse with lukewarm saline solution, and avoid spicy, highly acidic, or hot foods. Minimize speaking to reduce strain on the vocal cords, maintain good oral hygiene, and support the recovery from throat inflammation.

Generally, when symptoms of sore throat are mild, a small amount of vinegar may be used as a cooking seasoning. However, it is not recommended to consume vinegar directly or if symptoms are severe. Detailed explanations are as follows:

In the early stage of throat inflammation, if symptoms are limited to slight dryness or itchiness without obvious ulcers, using a small amount of vinegar as a seasoning in cooked or cold dishes—diluted by other foods—usually does not irritate the throat. The organic acids in vinegar have certain antibacterial properties, and moderate intake can stimulate appetite and help with nutrient intake. In such cases, rinsing the mouth with warm water after eating is sufficient.

Vinegar is highly acidic; drinking it directly can severely irritate the already inflamed and swollen throat mucosa, worsening pain and burning sensations, and may even trigger coughing. When throat inflammation is severe—such as when obvious ulcers, pus formation, or intense pain during swallowing occur—the mucosal lining is already fragile. Vinegar's acidity can further delay mucosal healing and prolong symptoms. Consuming vinegar on an empty stomach may also irritate the gastric mucosa, indirectly impairing recovery.

Diet during throat inflammation should be gentle and hydrating. Drink plenty of warm water or rinse with saline solution, avoid spicy, overly acidic, or hot foods, minimize voice use, and maintain good oral hygiene to support the resolution of throat inflammation.

What symptoms are associated with yellow phlegm from coughing?
Cough with yellow sputum generally indicates bacterial respiratory infection, lung heat syndrome, bronchitis, pneumonia, or postnasal drip caused by sinusitis. Bacterial invasion of the respiratory mucosa triggers an inflammatory response, leading to increased mucus secretion that turns yellow. In addition to yellow sputum, symptoms often include worsening cough and sore throat; some individuals may also develop fever. The more severe the inflammation, the darker the sputum color may become.

Can I eat bird's nest during my menstrual period, and why?
Bird's nest is rich in high-quality protein, amino acids, and other nutrients. For women with balanced or slightly deficient constitutions, consuming bird's nest during menstruation can help replenish essential nutrients, alleviate menstrual fatigue and weakness, and, due to its mild nature, moderate consumption will not significantly affect the menstrual cycle. However, for women with a heat-prone constitution, eating bird's nest during menstruation may exacerbate internal heat, leading to symptoms such as dry mouth and sore throat.

What should I do if I have yin deficiency with internal heat, as well as poor spleen and stomach function?
Under normal circumstances, internal heat due to yin deficiency accompanied by poor spleen and stomach function may be caused by factors such as dietary imbalance, emotional distress, chronic gastritis, irritable bowel syndrome, or stomach yin deficiency syndrome. Improvement can be achieved through lifestyle adjustments, medication, or other methods based on individual conditions. Avoid staying up late to prevent depletion of bodily fluids, and maintain focus during meals without distractions.
