It is extracted and processed from the blood of healthy people and injected directly into the patient's body. Its main function is to enhance people's immunity and resistance. Clinically, it is mainly used for the treatment of shock and cerebral edema caused by blood loss, trauma and burns, as well as the treatment of critical illness such as edema or ascites caused by liver cirrhosis and kidney disease, as well as patients with hypoalbuminemia.

It is a manifestation of human body function decline or endocrine imbalance. It is very different from the renal insufficiency or failure described in Western medicine.

Taking albumin has no meaning or effect.
