Introduction
Under normal circumstances, the risks and side effects of Houttuynia cordata (fishy-smelling herb) include inducing bad breath, allergic reactions, spleen and stomach deficiency-cold, kidney function impairment, and gastrointestinal discomfort. Specific details are as follows: 1. Inducing bad breath: Houttuynia cordata has a strong fishy odor. After consumption, it can easily leave an unpleasant smell in the mouth. If not properly addressed, this may lead to halitosis.

Generally, the potential risks and side effects of Houttuynia cordata (fishy-smelling herb) include inducing halitosis, allergic reactions, spleen and stomach cold deficiency, kidney function damage, and gastrointestinal discomfort. The specific details are as follows:

1. Inducing halitosis: Houttuynia cordata has a strong fishy odor, which may leave an unpleasant smell in the mouth after consumption. If not promptly addressed, it may lead to halitosis.

2. Allergic reactions: Houttuynia cordata contains allergenic components, such as houttuynin. These substances may easily trigger allergic reactions in some individuals. Mild symptoms may include skin itching, rash, and swelling, while severe cases could even experience anaphylactic shock, which can be life-threatening. Therefore, individuals with allergic constitutions should use Houttuynia cordata cautiously.

3. Spleen and stomach cold deficiency: Houttuynia cordata has a cold nature and excessive consumption may impair the yang energy of the spleen and stomach, leading to spleen and stomach cold deficiency. Symptoms such as abdominal pain, diarrhea, and indigestion may occur. Long-term consumption may further exacerbate cold deficiency symptoms.

4. Kidney function damage: Houttuynia cordata contains aristolactam, a substance that may cause kidney damage and lead to reduced kidney function when consumed over a prolonged period. It may result in abnormal kidney function indicators such as elevated creatinine and blood urea nitrogen levels, and severe cases may develop aristolochic acid nephropathy.

5. Gastrointestinal discomfort: Houttuynia cordata is not easily digested, and excessive consumption may cause gastrointestinal discomfort, such as bloating, abdominal pain, and nausea. Additionally, it may irritate the gastric mucosa, potentially leading to gastric diseases such as gastritis.

Individuals with allergic constitutions, spleen and stomach cold deficiency, or impaired kidney function should use Houttuynia cordata cautiously or under the guidance of a physician.
