Introduction
Houttuft root usually refers to Houttuynia cordata. Consuming too much is generally harmful to the body. It may impair digestive function, causing bloating and abdominal pain. For individuals with inherently weak and cold spleen and stomach, excessive consumption could worsen the deficiency and cold condition. Houttuynia cordata contains aristolochic acid, a substance that may increase the metabolic burden on the kidneys; therefore, excessive intake could lead to kidney damage.

Houttuynia cordata, commonly known as "Zhe'er Gen," is generally harmful to the body when consumed in excess. For example, it may lead to impaired digestive function, aggravated spleen and stomach cold deficiency, and kidney function damage.

1. Digestive Function Impairment

Houttuynia cordata has a relatively cold nature. Excessive consumption may impair digestive function, leading to symptoms such as abdominal distension and pain.

2. Aggravation of Spleen and Stomach Cold Deficiency

If an individual already has a weak and cold spleen and stomach, consuming too much Houttuynia cordata may worsen this condition.

3. Kidney Function Damage

Houttuynia cordata contains aristolochic acid, a substance that may increase the metabolic burden on the kidneys. Therefore, excessive intake could potentially cause kidney damage.

In addition, it may also increase the liver's metabolic load, causing discomfort. For the sake of health, it is advisable to consume Houttuynia cordata in moderation.
