None of the claims reported by George Merkl and others have undergone testing in animal studies, or in controlled clinical trials designed to determine, scientifically, the true effect, if any, of the 'treatment'. Merkl claims that chondriana are synthesized from DNA and can produce nucleoli. None of these claims are based on known anatomical and physiological facts. No scientific evidence supports the claim that chondriana exist, or that they create interferon or stimulate interleukin-2 or lymphocyte production, or have any role at all in the immune system. Nausea, vomiting and headaches may sometimes occur.
Treatment can last for several months.
