Can Houttuynia cordata tea be consumed long-term?

Generally speaking, Houttuynia cordata tea is not recommended for long-term consumption. It is advised to drink it only short-term when specific conditions such as excessive internal heat or mild inflammation occur, and only under medical guidance. Detailed explanations are as follows:

When symptoms such as wind-heat感冒 (wind-heat感冒 should be replaced with "wind-heat感冒" if保留中医术语, or alternatively translated as "wind-heat感冒" could be "wind-heat感冒" if contextually appropriate), sore throat, or lung inflammation occur, drinking an appropriate amount of Houttuynia cordata tea under a doctor's guidance can leverage its properties of clearing heat, detoxifying, reducing inflammation, and fighting bacteria. Short-term consumption may relieve discomfort and aid recovery, but usage should discontinue once symptoms improve; it should not be consumed regularly as a daily beverage.

In most cases, long-term consumption of Houttuynia cordata tea is unsuitable. Due to its cold nature, prolonged consumption may damage the yang energy of the spleen and stomach, leading to spleen and stomach cold deficiency, causing symptoms such as abdominal pain, diarrhea, and loss of appetite. Even for individuals without obvious discomfort or with generally good health, long-term consumption can disrupt the body's yin-yang balance and harm health. For those with weak spleen and stomach or yang deficiency with cold constitution, consumption may worsen existing symptoms and impair normal bodily functions.

Before drinking Houttuynia cordata tea, individuals should clearly understand their physical condition. Long-term self-administration is not advised. If symptoms occur requiring its use, consult a physician first, and strictly follow medical advice regarding dosage and duration to avoid adverse effects on health due to improper consumption.
