There are many western medicines to reduce edema. First, we need to clarify the cause of edema and then determine what kind of western medicine to choose for treatment. For edema caused by poor cardiac function, it is necessary to choose cardiac and diuretic drugs for treatment, such as digoxin to strengthen the heart and increase the amount of blood returned to the heart, and furosemide to promote the discharge of water from the body. For edema caused by the decrease of albumin in the body due to various diseases, direct input of albumin can also be used to reduce edema by increasing the colloid osmotic pressure of the body; for swelling caused by local allergic factors, topical application of cycloheximide cream can be applied, and oral administration of loratadine or vitamin C and calcium gluconate can also be considered.
