Medicine is one of the effective treatments for most diseases. However, in order to achieve the most optimal effect, in the process of using the drug, it is necessary to pay attention to a number of issues such as drug preservation, drug interactions, drug combinations, etc. effectiveness of the medication the patient is taking.

Placebo is a medical treatment that does not use the active ingredients of the drug to cure the disease but relies on the beliefs of the patient. This method does not work to cure the disease completely, but only improves the symptoms of the disease or health condition to a specific extent.
