The Midland Plant contained an auxiliary laboratory which fed data to the main Cerophyl laboratory in Kansas City. The Midland laboratory continues to be operated by Pines International
From the start, the data were impressive. Again, using only a small amount in the diet, studies with guinea pigs confirmed the same results as with chickens; i.e., dried cereal grass produced obvious health improvements. All farm animals benefitted from the blood building components in the dried powder. The animals had larger litters, healthier litters, richer milk, more milk. All the animals showed marked improvement in overall health with less disease and infections with less than 10% added to their rations.
Using Cerophyl, Doctors and Hospitals were finding similar results. Cerophyl quickly became the world's first multi-vitamin before synthetics came on the market. Newspapers and magazines such as Time, Reader's Digest and Business Week were sharing Dr. Schnabel's findings..
As synthetic vitamins became more common, the popularity of Cerophyl's use as a vitamin waned. In 1976, Pines International re-introduced essentially the same product, Pines Wheat Grass, as a dark green vegetable, using the same standards established by Cerophyl for growing, harvesting and storage. They also continued to use the same oxygen-free amber glass bottles with special metal caps to prevent oxidation and loss of nutrients.
Studies published in the early part of the 20th Century had shown that the chlorophyll molecule was very similar to the heme molecule that makes up red blood cells. In 1927, Charles Schnabel reasoned that green vegetables would build blood and stimulate chickens to produce more eggs.
At the time he started his research, poultry farmers were lucky if 30% of their chickens laid eggs each day. He tried many vegetables including the greens from turnips and mustard and even alfalfa with no success. Three years later in 1930, Schnabel dried some young cereal grass leaves that were harvested just before the jointing stage. He added a small amount of the grass powder to the food for 106 hens and suddenly started gathering more than 100 eggs each day.
As a millfeed chemist, Schnabel was anxious to try the unjointed cereal grass on other animals, including humans,. so he established a company that would research these grasses for animal feeds and a company named, "Cerophyl," which would supply dehydrated cereal grass tablets and powder for human research.
To keep up with the growing demand, Schnabel established a production facility at Midland, Kansas, just north of Lawrence. He favored the rich glacial soils that are only found in northeastern Kansas.
