ABSTRACT
Before discussing vitamins it is necessary to know something of the history and nature of vitamins. The name, vitamine, traces back to 1911 when Casimir Funk applied the name to substances that had some curative properties for that dreaded Oriental disease known as beri-beri. This was a disease very common in the Orient where the diet consisted of polished rice. The cause and cure of the disease had never really been understood by the medical men.
Since 1911 many of the best chemists and research men have been working on vitamins and much new information on the subject has been obtained. The scientific and chemical journals have had many articles bearing on the subject, but, as yet, the exact chemical nature of vitamines remains to be determined. At the present time there are three known vitamins necessary for health and growth with two undetermined, one of which prevents rickets, while the other has a marked influence on reproduction.
