Cernilton also appears capable of protecting the liver from the effects of some toxins, according to animal studies from Poland. A preliminary report from Ukraine on the use of flower pollen in humans with rheumatoid arthritis suggested positive effects on related disorders of the liver, gallbladder, stomach, and intestine. Pollen extracts have been used orally to desensitize people to plants they are allergic to. For example, people with hay fever allergies to grass pollen were asked to place drops of liquid grass pollen extract under their tongue daily for three weeks using a gradually increasing concentration in a double blind study. During the next allergy season they had significantly less severe hay fever symptoms than a group given placebo drops.
Most noncultivated plants produce pollen.
It is not clear which plants produce the most effective pollens. Some of the most common pollens used are timothy grass, corn, rye, and pine. Cernilton is an extract of several rye pollens, and it is also produced under the name Prostaphil . Because pollen is not an essential bodily constituent, deficiencies do not occur. The optimal intake of pollen is unknown.
