The author found that pectin with a purity(the content of Gal-A (galacturonic acid)) greater than 98% has a certain therapeutic effect on patients with chronic kidney disease, especially those with renal failure and uremia. We will show the relevant results that can support the above findings through animal experiments and clinical trials respectively. We are surprised that not only can it rapidly reduce and maintain serum creatinine levels for a period of time, allowing patients to stop dialysis and stay away from dialysis, but also has amazing performance in reversing glomerular filtration rate and improving kidney size. This technology provides a new method to replace dialysis or kidney replacement therapy for patients with renal failure / uremia in the past.
