The Three Kinds of Cod Liver Oil 1849
Previously i skimmed this book and reported small sections on this blog and in the FAQ area of the web site. If you would like to review some of the previous citations within the book please check out the FAQ area of the website where it is currently posted.
I was working tonight and i found another citation to share. The goal Dr. De Jongh's work was to study the 3 different types of Cod Liver Oil; Pale, Light Brown and Brown Cod Liver Oil, and make a detailed report. I don't know how i missed the conclusion to Dr. De Jongs work in the original post.
....The brown Cod Liver Oil has proven itself a most powerful remedy in rheumatism and scrofula. Now, I have found, in my chemical analysis, a quantitative difference between this and the other sorts of Cod Liver Oil. The constituent parts, which exist in great proportions in the brown Cod Liver Oil, must, therefore, be considered as those which fulfill the most important indications. The neutral fat, the iodine,phosphorus, the inorganic salts, exist in the same proportions in the other kinds of oil, which are not supposed to be particularly efficacious in scrofula and rheumatism; it is, therefore, fair to assume tha the brown Cod Liver Oil owes its great power to the biliary matter and butyric acid, which exist in it in much larger proportions than in the lighter-coloured oils.
I like history and think it is special to note that in the mid 1800's the question of what Cod Liver Oil is best is replicated today. The conclusions/studies where completed in the 1800's without full knowledge on why the brown Cod Liver Oil is best and today we re-ask the question. What is cool is the conclusion is just as clear today as it was in the 1800's, the Brown Cod Liver Oil is best.
Maybe we don't have to know why. 100 years from now we will re-ask the same question and not realize the question has been answered many times in history with the same conclusion but using different reasoning. Will we ever learn to the point of not re-asking the same question? My guess is it is our nature to repeat history.
