Different kinds of drugs are used as a treatment from the start of the world. Plants, chemicals, and animal parts are used to create drugs. Scientists are working hard to try to use plants, chemicals and animal parts together to create an effective medicine for diseases. History of such combined form of treatment is very long and after generations and generations it comes to the latest form we have today. Technological improvements and availability of chemical resources are changing the techniques of treatments and surgeries.

The history of using the chemicals and drugs together as medicine to cure people started from 10th century by an experiment of a Persian scientist named Muhammad Ibn-e- Zakriyya-al Razi. He introduced some chemical treatments with chemicals like copper, arsenic, salt, sodium, gold, coral, alcohol, and ammoniac etc. His idea of using chemical with drugs for medication was very successful. He treated many people form of diseases, of his time. Diseases related to stomach, hair, skin and lungs were at their peak that time of the history. He was named as a father of chemotherapy ideas as he introduced an idea of chemical and drugs together for medication. It was not named chemotherapy that time as therapy was named recent times.

The drug which was used for chemotherapy was an accidental creation. The drug was not used for specially the purpose of cancer chemotherapy. The history of cancer chemotherapy started with a chemical warfare. Mustard gas was a chemical warfare used during World War I, which killed some people and produced very bad effect on many more. During World War II some of the people were accidentally came under a war operation with mustard gas. It was discovered that these people had very low number of white blood cells in their body. The result was shocking for scientist of that time. They thought that if an agent can kill white cells it may work on cancer cells too.

Scientists in 1940’s tried an experiment on patients with white blood cell cancer. These patients were given the medicine of gas by injection directly into veins. It was seen that the condition of these patients were improved temporarily. The result forced scientists to under go some research and further experiments in order to find the best improved form. The researchers used many different other substances in their experiments and found some more improvements. There were many different drugs used to find the needed result. The experiments were very much positive and new drugs were come into existence. Due to new drugs, there were many treatments available for cancer patients.

Chemotherapy is the latest form of those experiments with the involvement of multi billion dollar research centers. Today, pharmaceuticals and medical research centers are spending billions of dollars to create chemotherapy treatment with fewer side effects. It is very interesting to know that a medical treatment is created by accidental use of warfare. If mustard gas was not used in World War I than there may still be no drug treatment for cancer patients.
