Cancer of Houttuynia? An article tells you the truth
Jul 31, 2018

Houttuynia cordata, also known as folding ear root, is a kind of plant that is homologous to medicine and food. In addition to traditional Chinese medicine prescriptions often add this medicine, usually in the folk, will also be as diuretic, fire-reducing medicine tea, boiled daily drinking. It can be said that as long as there are some Chinese people who know something about Chinese medicine, they are very familiar with it. However, the rumor that Houttuynia contains a high carcinogen, aristolochic acid, has not been interrupted. For this reason, many people are in the heart, dragged and dragged, even making up their minds.



However, Houttuynia cordata is really as legendary as it contains high carcinogens.


Before we say Houttuynia cordata, we need to understand several nouns, Aristolochia, aristolochic acid, aristolochic lactam. Aristolochiaceae is a division of the plant kingdom. Aristolochic acid is a chemical constituent and aristolochic lactam is a metabolite of aristolochic acid. Aristolochic acid is metabolized into aristolochic lactam when ingested in the body, which can cause DNA damage and subsequent cancer. Aristolochidamide is mainly divided into two kinds of I and II. Aristolochidamide -I can cause damage to the liver and has a strong carcinogenicity, and aristolochidamide -II is not toxic.


Houttuynia contains aristolochic lactam - BII, AII and FII, that is, class II aristolochic amide, so does not have carcinogenicity, can be safely eaten.


In fact, Houttuynia cordata Houttuyniae not only does not cause cancer, but also has many pharmacological effects.


1. antibacterial effect

The researchers have done an in vitro bacteriostasis test, which showed that Houttuynia has obvious inhibitory effect on kapara, Staphylococcus aureus, bacilli, and pneumococcus, and has obvious inhibitory effect on Escherichia coli, bacillary bacilli, proteus, diphtheria and Mycobacterium. The test tube dilution method was used to study the inhibitory effect of honeysuckle, forsythia, houttuynia and other traditional Chinese medicine on Staphylococcus aureus. The results showed that the Bacteriostasis of Houttuynia cordata was the strongest and the forsythia was the weakest.


2. antiviral effect

Houttuynia Houttuynia has an inhibitory effect on various viruses. It has been found that the extract of Houttuynia Houttuynia has a significant inhibitory effect on Asiatic virus, influenza virus and hemorrhagic fever virus. It was observed that Houttuynia cordata Thunb. could inhibit influenza virus and postpone the cytopathic effect of virus in primary monolayer epithelial cells of human embryonic kidney.


3. enhance the immune function of the body

Houttuynia cordata Thunb. can enhance the phagocytosis of leukocytes, enhance the non-specific and specific immunity of the body, significantly increase the proportion of peripheral blood T lymphocytes. Studies have shown that the synthesis of houttuynin can significantly enhance the specific and non-specific immune function of mice with immunodeficiency induced by splenectomy.


4. anti-inflammatory effect

Houttuynia cordata Thunb. Decoction can inhibit formaldehyde-induced foot swelling, inhibit serous exudation, promote tissue regeneration and wound healing.


5. antitumor effect

In recent years, researchers in our country have found that houttuynia and new Houttuynia have obvious inhibitory effects on Ehrlich ascites cancer in mice, and the highest inhibitory rate of mitosis to cancer cells is 45.7%. Clinical trials have shown that Houttuynia cordata Thunb. can improve the phagocytosis of macrophages in vivo, increase the body's anti-infection and specific humoral immunity. It has strong antiviral, anti-aging and anti-cancer effects.


6. analgesic, hemostatic and diuretic effects

Some scholars believe that the mechanism of the diuretic of Houttuynia Houttuyniae is due to the aqueous solution containing quercetin in its extract, so it has the effect of strong diuresis and prevention of capillary brittleness. Flavonoids from Houttuynia cordata Thunb have better expectorant, cough relieving and certain antiasthmatic effects. In 2003, during the period of SARS, Houttuynia cordata Thunb was used as a very important medicinal material.


7. health care

In addition to the above effects, Houttuynia has the effect of anti radiation, not only for aircrew, but also for people who are often close to the radiation sources, such as X and computer operators, and people who often watch TV. Houttuynia cordata tea can maintain soft blood vessels, and can prevent hypertension, coronary heart disease caused by arteriosclerosis. Insist on drinking Houttuynia flower tea can also cure rheumatic joint swelling and pain, allergic rhinitis and so on.


In summary, through the research on the chemical composition, health care, clinical application, development and utilization of Houttuynia cordata Houttuynia, it shows that the bioactivity of Houttuynia Houttuyniae is high, widely used and effective. It is worthy of further application.


In addition, there is no need to panic too much for so-called carcinogenic vegetables. Cancer is the result of a variety of factors, although some vegetables contain carcinogenic ingredients, but their content is not very high. As long as they are reasonably cooked and controlled, they have little effect on cancer. In addition, not every kind of vegetable is suitable for the human body to eat a large number of long-term, to ensure the diversity of diet, regular and healthy work and rest is the fundamental prevention of cancer.
