Banting took on Charles Best to assist him in isolating the insulin. Together, the three scientists successfully ended with the discovery that insulin could be used to treat patients diagnosed with diabetes. A year later, scientist James Collip purified the insulin, finally making it ready to use as an official form of treatment by injection.
This was a ground breaking discovery in medical history because it occurred in a time where innovation, including medical advancements, were highly encouraged. Also, it was discovered in a time where increasingly more people were diagnosed with the disease, ultimately, saving many lives. The treatment became available to patients in North America, overall, revolutionizing the medical field as a whole.
