Paul Ehrlich

We must learn to shoot with magic bullets.

The body does not act unless it is fixed.

The side chain theory is an attempt to explain the processes of immunity on a chemical basis.

The goal of chemotherapy is to find substances that are toxic to the parasite but harmless to the host.

The problem is to find a substance which, when introduced into the blood, will kill the invading organisms without injuring the host.

I have always been convinced that the future of medicine lies in chemistry.

The more we know about the chemical structure of the cell, the better we will be able to fight disease.

We must not only cure, but also prevent.

The immune system is a chemical system.

The future of medicine belongs to those who can combine chemistry and biology.

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.

The organism is a chemical factory.

We must understand the enemy before we can defeat it.

The cell is the battlefield of disease.

The art of medicine consists in amusing the patient while nature cures the disease.

The more specific the drug, the more effective it will be.

We are at the beginning of a new era in medicine.

The search for the magic bullet is a long and arduous one, but it is worth it.

The body has its own defenses, and we must learn to enhance them.

The key to understanding disease is to understand the cell.
