If you experience symptoms like a cold and heatiness, you can appropriately consume some foods that clear heat and detoxify, and reduce internal heat. For instance, you can appropriately eat some grapefruit, apples, pears, or oranges, and kumquats are also good choices. Additionally, you could eat some vegetables like loofah or bitter gourd and winter melon, which can help clear heat, detoxify, reduce swelling, and promote urination. It is also advisable to consume some loquat, or appropriately eat some bok choy, lettuce, and celery. It is important not to consume nourishing foods that are too rich, such as mango, durian, longan, lychee, and goji berries, as they might worsen the condition. Moreover, remember to drink plenty of water to promote metabolism and enhance your immune system.
