2 role and use

Central excitatory drugs, similar to caffeine, have strong and lasting diuretic effect and weak central excitatory effect. Suitable for heart and kidney edema. Because of its low toxicity, it can also be used for renal insufficiency. Urea can reduce blood volume and cause dehydration of the body. Long-term use of urea will cause the body's water electrolysis balance to be out of control.

In life, many people regard diuretics as diet pills. In fact, diuretics don't help to lose weight at all, just water in and out, and have no metabolic effect on fat. Some athletes mistakenly take urea as a stimulant, such as the world's first flying fish, and the Olympic and World Championships men's 50m freestyle champion Siello 20 1 1 tested positive during the Brazilian National Championships in May. Surprisingly, the Brazilian Swimming Association only announced the cancellation of the results and warned Xiluo, but did not announce further suspension. The Brazilian Water Sports Association said in official website: "Urea is not helpful for improving performance."
