What is the effective treatment for pulmonary infarction

Condition analysis:
Lung infarction, death of one or more sections of lung tissue due to deprivation of an adequate blood supply. The section of dead tissue is called an infarct. The cessation or lessening of blood flow results ordinarily from an obstruction in a blood vessel that serves the lung. The obstruction may be a blood clot that has formed in a diseased heart and has travelled in the bloodstream to the lungs, or air bubbles in the bloodstream (both of these are instances of embolism), or the blockage may be by a clot that has formed in the blood vessel itself.

Instructions:
It's suggested that patients with pulmonary infarction should take Chinese medicine, such as Liu Wei Di Huang Wan, Bu Zhong Yi Qi Wan, Gui Qi Wan, and Shiquan Dabu Pill. Take the four medicines together, three times a day, one month for a course of treatment.
