What is purslane? What does it do?
Purslane, also known as longevity vegetables, it is not only a wild vegetable, but also has a medicinal effect, which can not only reduce liver fire, purify the heart fire, but also clear intestinal heat, detoxification, conditioning constipation, and exorcise stool.

Purslane cold sour, returned to the heart meridian, liver meridian, large intestine meridian, the more menstruation the more extensive the scope of treatment. It is rich in dihydroxyethylamine, malic acid, glucose, calcium, phosphorus, iron, as well as carotene, vitamin B, vitamin C and other nutrients. Regular consumption of purslane can not only supplement the body's nutrition, but also have no worries about increasing cholesterol, which is a natural good vegetable medicine.
Therefore, many people like to make purslane into a cold mixture or stir-fry to eat, and some people say that purslane can be boiled and drunk. However, pregnant women are best not to eat purslane, because purslane is slippery and has the effect of slippery tires.
Many people like to eat it cold or stir-fried, and the Internet also says that purslane can be boiled and drunk!
After Grandpa ate purslane, blood creatinine soared!
But recently, a 70-year-old uncle had diarrhea because he ate purslane. This uncle usually has any discomfort in his body, so he goes to grab herbs to eat.
After that, Uncle took purslane 2 times, and then his stomach was swollen and painful, so he went to the hospital for examination.
The results came out, blood creatinine 527umol/l!
Causes of spikes in blood creatinine
Such a high blood creatinine indicates that there is a serious impairment of kidney function, why is this so?
The doctor first thought, is it because the uncle has eaten Chinese medicine for more than 10 years and caused drug-induced kidney damage? For example, chinese medicines such as aristolochic acid, resulting in chronic interstitial nephritis?
Uncle said that he did not remember what herbs he had eaten in the past 10 years, let alone what ingredients the herbs contained, so he could not provide specific medication lists. Therefore, the doctor is not easy to judge.
Is it possible that chronic nephritis is still possible? Hypertension, diabetes-related kidney disease? And so what about common causes of kidney failure?
Not really. Uncle's urine routine, in addition to the low point of urine specific gravity, other basic normal, no red blood cells, proteinuria, 24-hour urine protein quantification is normal, urine volume is normal. There was no previous hypertension, diabetes, etc.
Combined with the fact that the onset of the uncle is relatively urgent, there is no common complication of chronic kidney failure such as renal anemia and hypertension, the doctor considers "acute kidney injury" and admits him to the hospital.
Two days after admission, Uncle's serum creatinine rose from 527umol/l to 792umol/l.
To determine the cause, doctors gave him a renal aspiration biopsy, which reported acute tubulointerstitial nephritis and oxalate nephropathy.
Above are his renal tubules, and those shiny diamond-like things are oxalate crystals.
Only then did I know that there was a large amount of oxalate deposited in the renal tubules, blocking the renal tubules, causing acute kidney injury and elevated serum creatinine!
Why does Uncle have so many oxalate crystals?
It turned out to be because I had eaten too much purslane!
In fact, the content of purslane oxalic acid is very high. In addition to purslane, there are also amaranth, spinach, beet leaves and so on.
Seeing this, I thought to myself, will I not buy these dishes to eat in the future?
In fact, the dish is no problem, it can be bought to eat, but you need another way to cook these dishes, because the oxalic acid is soluble in water, so the first step is best to blanch these dishes in water, about ten or twenty seconds, and then pour out the water after blanching the dish, and then fry, so that you can greatly reduce the content of oxalic acid.
Because some people think that the water boiled by purslane can clear heat and detoxify, they drink a bowl of thick oxalic acid-rich water.
And the uncle is because of the gastrointestinal discomfort of eating purslane for a few days, so oxalic acid is more likely to be deposited.
In gastrointestinal dysfunction, fat absorption is impaired, and a large number of free fatty acids in the intestine bind calcium ions, resulting in a decrease in the binding of oxalic acid to calcium, and a large amount of oxalic acid is absorbed into the bloodstream by the intestine. When oxalic acid is excreted through glomerular filtration and tubular secretion, it combines with calcium to form calcium oxalate crystals, which are deposited in the renal tubules, causing kidney damage. Calcium oxalate crystals can also aggregate to form kidney stones, which can lead to obstructive nephropathy and injure the kidneys.
Fortunately, after the symptomatic treatment of the uncle, his kidney function was restored, and the blood creatinine also dropped to normal values after more than 20 days.
In 2020, Old Li (pseudonym) from Wenzhou, 58 years old, heard that purslane has the effect of lowering blood sugar, so he bought 20 pounds in the vegetable market, dried and fried to eat.
However, after eating for a few days, Lao Li's legs swollen and painful, so he went to the hospital for examination, and the results showed that Lao Li suffered from acute kidney injury, color ultrasound showed that both kidneys had crystals, and punctures showed that the renal tubules were covered with kidney crystals.
There are many cases of oxalate kidney disease due to eating too many foods containing oxalic acid, in order to avoid repeating the same mistakes, it is best to eat less vegetables containing oxalic acid, or blanch these oxalic acid-rich vegetables in water before eating.
But not all people are suitable for eating foods containing oxalic acid, for example, people with weak ability to deal with oxalic acid, such as patients with intestinal diseases, poor kidney function and other diseases; menopausal women with decreased estrogen, which will affect intestinal function, resulting in more oxalate being absorbed into the human body; people who take excessive antibiotics, the number of microorganisms will be greatly reduced in the body, and these microorganisms are responsible for releasing enzymes that decompose oxalic acid, because the microorganisms are reduced, so the enzymes that break down oxalate are also reduced, thus leading to oxalate intolerance.
In order to avoid people around you eating too many vegetables containing oxalic acid, or miscooking vegetables containing oxalic acid and suffering from oxalate kidney disease, please forward this article to them!
