Eleuthero emulsion is a proprietary Chinese medicine injection preparation developed by China, which is extracted from the ginger family plant warm yujin and can reduce mitosis of tumor cells and induce apoptosis, as well as inhibit the growth of tumor cells, and has entered the medical insurance catalog. In clinical practice, it is mainly used for the adjuvant treatment of stomach cancer, intestinal cancer and lung cancer, and it is also effective for some patients with advanced tumors who develop thoraco-abdominal fluid. Since elemicin can pass the blood-brain barrier, it also has certain therapeutic effect on intracranial metastases and can be used for primary tumors and metastases in the skull. However, because of the obvious stimulation of peripheral vessels, it is better to give peripheral intravenous catheter input during intravenous infusion, which can reduce the stimulation of blood vessels. Elemicin was previously given in the presence of thoracoabdominal effusion, but it was later found to be more irritating to the pleura and to form jelly-like objects when injected into the thoracic cavity, so it is no longer recommended for thoracoabdominal injection.
