Discovered by the Japanese researchers in the 1920's, there are reams of literature in that country about the anti-histamic effect of this liver extract. Dr. Harrower who wrote the classic work "Practical Endocrinology" stated that Yakriton (contained in our product Antronex®) is "the detoxifying hormone of the liver." Antronex is rated according to the amount of Yakriton it contains. Yakriton is the blood-filtering fraction of the liver. So the product quickens the detoxification of the blood in its flow through the liver.
