Can Houttuynia cordata be steeped in water for long-term consumption?

Generally speaking, Houttuynia cordata should not be steeped in water for long-term consumption. The specific analysis is as follows:

Houttuynia cordata is a traditional Chinese herb that has functions including clearing heat and detoxifying, reducing abscesses and discharging pus, and promoting diuresis and relieving urinary difficulties. Short-term consumption of Houttuynia cordata tea may help alleviate certain symptoms. However, as it has a slightly cold nature, long-term consumption might irritate the gastrointestinal tract, leading to symptoms such as abdominal pain, diarrhea, nausea, and vomiting. Some individuals may be allergic to Houttuynia cordata, and long-term consumption could trigger allergic reactions such as rashes, itching, and difficulty breathing.

Long-term and excessive consumption of Houttuynia cordata tea may increase the metabolic burden on the liver and kidneys, potentially causing damage to liver and kidney function. Houttuynia cordata contains aristolactam components, which although different from aristolochic acid, may still harm the kidneys when consumed over a long period or in large quantities. Due to its cold nature, prolonged consumption may exacerbate cold body constitution, leading to symptoms such as cold hands and feet, sensitivity to cold, and frequent colds.

In addition, special populations such as pregnant women, lactating women, individuals with spleen-stomach deficiency and cold, and patients with hypotension should use Houttuynia cordata cautiously to avoid adverse effects on health. It is recommended to follow medical advice when using it, pay attention to moderate consumption, and monitor the body's response. If discomfort occurs, seek medical attention promptly.
