This dehydration can cause electrolyte imbalance by disrupting the delicate balance of essential minerals in the body. Furthermore, Rheum officinale contains compounds that may cause kidney damage if consumed in excess, potentially leading to acute kidney injury or chronic kidney disease. The repeated use of Rheum officinale can also cause electrolyte imbalance due to the loss of essential minerals, particularly potassium, leading to muscle weakness and cardiac arrhythmias.

In severe cases, the improper use of Rheum officinale can lead to kidney damage, which may result in chronic kidney disease and the need for long-term renal replacement therapy.
