Introduction
If allergic symptoms are caused by other factors such as pollen or dust mites, and there is no previous history of lychee allergy, a small amount of lychee may be cautiously consumed during the allergy period. Limit intake to 3–5 lychees, and observe for 20–30 minutes after consumption. If no new symptoms such as rash, itching, or difficulty breathing occur, it may be considered temporarily safe. This approach can help supplement nutrients such as vitamin C and glucose.
Individuals who are not allergic to lychee and whose allergic symptoms are unrelated to lychee may cautiously consume small amounts. However, those who are clearly allergic to lychee or are experiencing a severe allergic episode must strictly avoid consumption. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed explanation is as follows:
If allergic symptoms are caused by other factors such as pollen or dust mites, and there is no prior history of lychee allergy, small amounts of lychee may be cautiously tried during the allergic period. Consume no more than 3–5 lychees and observe for 20–30 minutes afterward. If no new symptoms such as rash, itching, or difficulty breathing occur, it may be considered temporarily safe. This approach can provide nutrients such as vitamin C and glucose without worsening the current allergic symptoms, although intake should still be controlled.
Once a lychee allergy is confirmed or if an individual is in the midst of a severe allergic reaction, lychee must be strictly avoided. Proteins and phenolic substances in lychee can trigger excessive immune responses, potentially worsening symptoms such as itching and swelling or even inducing anaphylaxis. Even if the current allergic symptoms are unrelated to lychee, the body's immune system may be unstable during an allergic episode, increasing the risk of developing a lychee allergy. Therefore, caution is necessary.
Before consuming lychee during an allergic period, ensure you are aware of your allergy history, start with a very small amount, and closely monitor your body's reaction.
