What are the benefits and effects of century eggs?
Generally speaking, the effects and benefits of preserved eggs (pi dan) include enhancing appetite, supplementing nutrition, clearing heat and relieving fire, sobering up and alleviating the effects of alcohol, and providing a rich texture. Detailed explanations are as follows:

1. Enhancing Appetite: Preserved eggs contain large amounts of minerals and protein. These components can stimulate the digestive system during the pickling process, promoting digestion and absorption of food, thereby enhancing appetite.
2. Supplementing Nutrition: Preserved eggs are nutrient-rich foods containing protein, fat, vitamins, minerals, and more. These nutrients help maintain normal physiological functions, promote growth and development, and enhance immunity.
3. Clearing Heat and Relieving Fire: Preserved eggs are cool in nature and possess the effect of clearing internal heat and reducing fire. They can be used to treat symptoms such as excessive internal heat, irritability, and thirst. Consuming preserved eggs in moderation helps alleviate these heat-related conditions and maintain bodily balance.
4. Sobering Up and Alleviating Alcohol Effects: Trace elements in preserved eggs can reduce ethanol concentration, thus helping to sober up and alleviate the effects of alcohol. Consuming preserved eggs in moderation after drinking can help relieve the irritation and damage caused by alcohol to the body.
5. Providing Rich Texture: Preserved eggs have a unique flavor and texture and can be added as an ingredient to various dishes, such as tofu with preserved egg, sweet and sour preserved egg, and lean meat congee with preserved egg. These dishes not only offer a rich taste but are also nutritious, providing essential nutrients to the body.
It is recommended to consume preserved eggs in moderation and to combine them reasonably according to individual constitution and needs. Additionally, individuals with specific diseases or symptoms should consume preserved eggs under the guidance of a doctor to ensure safety and effectiveness.
