Is it harmful to the body to eat too much heartleaf houttuynia (Houttuynia cordata)?
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.
