Introduction
When a baby's fever is caused by a heat-type cold, presenting symptoms such as fever, red and swollen throat with pain, and yellow nasal discharge, and it is confirmed that the baby is not allergic to Houttuynia cordata (fish腥草),适量 drinking Houttuynia cordata water under a doctor's guidance may help relieve symptoms by utilizing its heat-clearing and detoxifying properties. Houttuynia cordata water can help reduce throat inflammation, alleviate discomfort caused by fever, and support the baby's recovery.

Generally, fish mint water can be given to babies for fever caused by wind-heat without allergic reactions, following a doctor's advice. However, it should not be used when the fever is due to wind-cold or if the baby is allergic to fish mint. If any abnormalities occur, timely medical consultation is recommended. Detailed explanation is as follows:

When a baby's fever is caused by a wind-heat cold, accompanied by symptoms such as fever, red and sore throat, and yellow nasal discharge, and there is no allergy to fish mint, fish mint water may be given in appropriate amounts under a doctor's guidance. It has heat-clearing and detoxifying properties that can help relieve symptoms. Fish mint water can reduce throat inflammation, alleviate discomfort caused by fever, and aid the baby's recovery.

If the baby's fever is due to a wind-cold cold, characterized by chills, mild fever, and clear nasal discharge, consuming fish mint water may worsen the internal cold condition and aggravate the illness. Additionally, if the baby has an allergic constitution or is allergic to fish mint, drinking fish mint water may trigger an allergic reaction, such as rash, itching, and rapid breathing, which not only fails to relieve the fever but also poses additional health risks to the baby.

When considering giving fish mint water to a baby with fever, it is essential to consult a doctor first to identify the cause of the fever and assess the baby's health condition. Strictly follow medical advice regarding dosage and frequency, closely monitor the baby's response after consumption, and seek immediate medical attention if any abnormalities occur.
