Can patients with fever eat fennel?
Patients with fever can consume a small amount of fennel when they have a low-grade fever and no gastrointestinal discomfort. However, they should avoid consuming fennel during high fever or when experiencing gastrointestinal issues or heat-related symptoms. If any abnormalities occur, prompt medical attention is recommended. Detailed explanations are as follows:

When a fever patient has a low-grade fever (body temperature below 38°C) and does not experience gastrointestinal symptoms such as nausea, vomiting, or abdominal pain, consuming a small quantity of fennel will not significantly burden the body. Fennel contains nutrients like vitamins, which can provide some nourishment to the body. Additionally, its moderate consumption can stimulate appetite, helping patients eat more during illness and thereby supporting recovery.
If a fever patient's temperature exceeds 38°C, indicating a high fever, or if they experience severe coughing, sore throat, constipation, or other heat-related symptoms, or if they have gastrointestinal dysfunction, consuming fennel is not advisable. Fennel is warming in nature, and consuming it during high fever may intensify internal heat. Eating fennel while experiencing significant heat-related symptoms may worsen discomfort. Furthermore, when gastrointestinal function is weak, fennel may be difficult to digest, increasing the burden on the digestive system and potentially causing indigestion, bloating, or other issues that hinder recovery.
Fever patients should consider their body temperature, symptoms, and gastrointestinal condition before consuming fennel. During low-grade fever, a small amount may be cautiously tried while observing the body's response. If any discomfort or temperature elevation occurs, consumption should be stopped immediately, and medical advice should be sought promptly.
