Introduction
There is generally no saying that six types of people should not eat Houttuynia cordata (fish腥grass), but individuals with cold-deficient body constitution, weak spleen and stomach, allergies to Houttuynia cordata, impaired kidney function, or those currently taking special medications may experience adverse reactions after consuming it. Houttuynia cordata is cold in nature. Those with cold-deficient constitution inherently lack sufficient yang energy, often exhibiting symptoms such as cold intolerance, cold hands and feet, and pale complexion.
There is generally no saying that six types of people should not eat Houttuynia cordata, but individuals with cold-deficient body constitution, those with weak spleen and stomach, people allergic to Houttuynia cordata, patients with kidney insufficiency, and those currently taking special medications may experience adverse reactions after consumption. If abnormalities occur, prompt medical attention is recommended. Detailed explanations are as follows:
1. Individuals with cold-deficient body constitution: Houttuynia cordata is cool in nature. Those with cold-deficient constitution typically have insufficient yang energy, often presenting symptoms such as cold intolerance, cold hands and feet, and pale complexion. Consuming Houttuynia cordata may further deplete internal yang energy, worsening symptoms of cold deficiency and causing physical discomfort or harming health.
2. Individuals with weak spleen and stomach: Those with weak digestive systems often experience poor appetite, abdominal distension, diarrhea, and other symptoms. The cold nature of Houttuynia cordata may easily irritate the spleen and stomach, weakening their function and potentially worsening pre-existing digestive issues like indigestion and diarrhea, hindering recovery of spleen and stomach health.
3. People allergic to Houttuynia cordata: Some individuals are allergic to certain components in Houttuynia cordata, which may trigger allergic reactions upon consumption. Common symptoms include skin itching, red rashes, rapid breathing, and in severe cases, anaphylactic shock, which can be life-threatening. These individuals must strictly avoid consuming Houttuynia cordata.
4. Patients with kidney insufficiency: Houttuynia cordata contains a certain amount of aristolochic acid compounds. Although the levels are low, individuals with impaired kidney function may experience weakened metabolic clearance. Long-term or excessive consumption of Houttuynia cordata could lead to accumulation of harmful substances in the body, increasing the burden on the kidneys and affecting renal function.
5. Individuals currently taking special medications: Houttuynia cordata may interact with certain medications, affecting their efficacy or causing adverse reactions. For example, individuals taking sedatives or antihypertensive drugs should consult a physician before consuming Houttuynia cordata to avoid interference with drug effects and ensure medication safety.
In daily life, individuals should understand their own physical condition before consuming Houttuynia cordata. Those belonging to the above-mentioned unsuitable groups should avoid consumption. If unsure whether it is suitable for you, consult a professional physician or nutritionist to make informed decisions based on individual constitution and health status, preventing potential adverse effects on the body.
