Medications can be good for the body and bad. They can be made from medicinal substances of plant and animal origin as well as many organic and inorganic synthetic products that serve to detect, control and treat diseases in the body, or relieve and alleviate pain. In addition to the pills we call medicines, medicines also include blood and blood derivatives, and everything that is used from materials for medical purposes. Medicines are also called useful poisons, because poisons in small doses are useful medicines. The basic condition for the use of the drug is efficacy, reliability, safety, quality with clear instructions for use, and the method and area of action.
