Houttuynia cordata is a herb included in the Chinese Pharmacopoeia, and it is also a kind of food with the same origin of medicine and food, because people often eat the white rhizome of Houttuynia cordata, so the folk will also call it the folded ear root, and for various reasons, Houttuynia cordata is named the name of harmful grass in the mouth of some people, so is Houttuynia cordata a good thing, or is it a harmful herb that is harmful to health? What impact will long-term consumption have on life?
Through the example of Aunt Li, we can understand a rough idea, Guangxi's 43-year-old Aunt Li is in good health, although there are occasional small colds and other minor diseases, but to this age, she has not had surgery, has not been hospitalized, and there is no chronic disease torture, but recently Aunt Li has been tortured by a small problem, it turns out that Aunt Li's mouth will grow one or two ulcers every three or five times.
Although the wound on the epidermis of the mouth looks inconspicuous, it hurts really badly, and it hurts badly when the tongue touches it, not to mention the time to eat, the food touches the wound and hurts even more, Aunt Li really doesn't even dare to eat slightly hot food, and this small ulcer is still very difficult to heal, it can't heal for about a week when it pops up, and even after healing, after a day or two, the ulcer will pop up inexplicably.
From a medical point of view, Aunt Li is now a manifestation of recurrent oral ulcers, fortunately it is not serious, just a mild type of disease, which is a very common disease, is a manifestation of oral mucosal abnormalities, in the mainland's 2012 "Guidelines for the Diagnosis and Treatment of Recurrent Aphthous Ulcers" statistics, 10% to 25% of the population in the mainland suffer from different degrees of recurrent oral ulcers, and the onset time is not fixed, there is no specific onset time and season.
So from a medical point of view, mouth ulcers are indeed not a big problem, and they can heal without treatment, but the long-term pain also makes it extremely inconvenient for Aunt Li to eat, so Aunt Li still wants to completely solve this problem, so she went to the hospital for treatment and diagnosis.
The doctor said that Aunt Li's mouth ulcers were mainly because the resistance was too low, so he prescribed some vitamins to Aunt Li, and also prescribed some metronidazole anti-inflammatory drugs, Aunt Li bought vitamin groups, but she didn't ask for anti-inflammatory drugs, she felt that it was not necessary to take anti-inflammatory drugs for an ulcer, in fact, Aunt Li's idea is very commendable, the abuse of antibiotics in the mainland is very rampant, and the random use of antibiotics will also lead to the slow evolution of bacteria to produce drug resistance, so the effect of antibiotics will become weaker and weaker, and even superbugs will appear。
Therefore, in the face of some minor diseases, whether you can use antibiotics or try not to use them, immunity is the best medicine to fight these diseases. However, Aunt Li took vitamin tablets for a week, and the ulcer in the mouth did not improve, through the reminder of a friend, she decided to go to see a Chinese medicine again, the doctor looked at the symptoms of Aunt Li's mouth ulcer, and judged that Aunt Li was a mouth ulcer caused by the fire of the spleen and stomach according to Aunt Li's yellowish and dry tongue.
Because the symptoms were very mild, the doctor did not prescribe prescriptions such as Qingqi San and Jade Nu Decoction to Aunt Li, and he said to Aunt Li: Isn't it the season to eat Houttuynia cordata, you go back and eat Houttuynia cordata cold, and you can also mash some Houttuynia cordata and hold it in the affected area, and this mouth sores will definitely be cured within a week.
At this time, Aunt Li was surprised, unlike Western medicine prescribing a lot of antibiotics, Chinese medicine does not even prescribe medicine, and for this Houttuynia cordata, Aunt Li also showed quite a lot of criticism, she vaguely remembered that someone told her about Houttuynia cordata is poisonous, saying that Houttuynia cordata is a harmful grass! So she asked the doctor this question.
The doctor's statement that Houttuynia cordata is poisonous is a complete rumor, Houttuynia cordata is a non-toxic food, with the effect of eliminating carbuncle and draining pus, diuretic and drenching, and is a common heat-clearing and detoxifying drug, so for Aunt Li's mouth ulcers, Houttuynia cordata detoxification and carbuncle effect can achieve a good effect, and Houttuynia cordata is also a very common food in South and Southeast Asia, and the source of harmful grass is because of the grass and grass of Houttuynia cordata injection during the SARS period, which caused adverse reactions and caused death after this injection was injected into the human body.
This is not Houttuynia cordata's fault, this is caused by the pharmaceutical company's shoddy production and not doing a good job in clinical trials and hastily listing it, so Houttuynia cordata has the name of Houttuynia cordata on its back, which is really a trumped-up crime, after listening to the doctor's explanation, Aunt Li knew that her knowledge was too one-sided, and after eliminating her anxiety, she went home and began to eat Houttuynia cordata.
After eating it for 4 days in a cold way, Aunt Li found that there was no more pain in her mouth, and when she looked at her mouth in the mirror, the ulcer disappeared, and the troubles that had plagued her for several months were easily solved by eating vegetables, and Aunt Li began to be impressed by this inconspicuous dish, and continued to eat Houttuynia cordata for a week, and Aunt Li found that the ulcer did not recur.
In this way, another 2 months have passed, Aunt Li basically eats cold Houttuynia cordata every day, and the ulcer is no longer traced, this recurrent ulcer is simply and completely cured by eating Houttuynia cordata, but Aunt Li has maintained this habit, Houttuynia cordata has many benefits, and Aunt Li is naturally willing to eat more
At this time, she thought of the doctor who helped her, so she found the doctor to express her gratitude in person, and he also told the doctor that in order to maintain her health, she still kept eating Houttuynia cordata every day, but she didn't expect the doctor to say to herself after hearing it: Although Houttuynia cordata has many benefits, you can't eat it like this, eating it every day for a long time may affect your health.
Then the doctor continued to emphasize: For these two types of people, it is even more important to avoid eating Houttuynia cordata, if you eat it regularly, it is tantamount to taking chronic poison!
For people with bad stomach, the rhizome of Houttuynia cordata is hard, containing a large amount of plant crude fiber, which is fine for ordinary people, and may also play a role in exercising gastrointestinal peristalsis ability to promote defecation, but for people with bad stomach, these rhizomes are very difficult to digest, it will greatly increase the burden of gastrointestinal digestion, and there will be more crude fiber to hinder the already weak gastrointestinal peristalsis, resulting in further confusion of digestive function.
And Houttuynia cordata is a cold plant, so for people with a bad gastrointestinal tract, the cold medicinal properties will aggravate the cold and dampness and trap the spleen, leading to diarrhea and abdominal pain, so for such people, it is necessary to avoid eating too much Houttuynia cordata.
For people with poor kidney function, Houttuynia cordata belongs to the Trisherbaceae family, containing a special substance Aristolochia lactam, which may combine with the DNA in the nucleus of kidney cells and cause irreversible damage to kidney cells, but not all Aristolochia lactams are strongly toxic to the kidneys, and the Aristolochia lactam component in Houttuynia cordata is A-II with unclear nephrotoxicity, so it is a pure rumor that Houttuynia cordata can cause cancer of the kidneys, but for the sake of caution, patients with kidney disease should still pay attention to eating less Houttuynia cordata to avoid unnecessary trouble。
But the benefits of Houttuynia cordata are very many, because it has a good effect on lung infections, and it has also made outstanding contributions to the fight against the epidemic during the SARS period, so if you often have symptoms such as cold and cough, then you can usually drink some Houttuynia cordata water, or eat some Houttuynia cordata, and Houttuynia cordata also has a good effect on joint pain, and if there is an old problem of joint pain, it can also be used appropriately.
However, it is also necessary to pay attention to the quantity, and it is not recommended to eat plants with cold properties for a long time and high frequency.
