A Skeptical Look at Antimalignocyt (CH-23)

Stephen Barrett, M.D.

Antimalignocyt—originally marketed as "CH-23," is an alleged cancer cure said to have been developed about 50 years ago by Prodan Hristov. The Association Antimalignocyt describes its history this way:

Prodan Hristov is a Bulgarian born in the village of Mrachenik, near Karlovo. In 1955 he emigrated to Vienna, Austria. He started studying medicine there and completed 7 semesters. But as it was not his dream he transferred into another major – Biochemistry—and he graduated it. He dedicated the first years after his graduation to scientific researches in the sphere of rejuvenation. However, at that time the number of oncological diseases was record-breaking in Vienna and he decided to direct his efforts to this sphere as he strived to get nearer nature and human biology. Only six month later he succeeded in discovering a medicine against cancer: Antimalignocyt [1].  

Antimalignocyt, which is administered intravenously, is said to be made from 2 herbs—peony and common mullein. One 5 ml vial is said to contain 500 mg of the active substances of these herbs bound to the amino acids glycine, alanine, L-valine, L-serine, L-cysteine, and L-asparagyne acid. Treatment is said to last 3-4 months [2].

The Association's Web site also states:

American Cancer Investigation

In the late 1960s, the American Cancer Society investigated CH-23 and found no evidence that its use can benefit cancer patients [4,5]. The society's reports—which referred to Hristov by his anglicized name, Prodan Christoff—stated:

Why I Am Skeptical

Searching Medline and several prominent herbal databases, I could find no evidence that peony and mullein have any anti-cancer properties. It's possible that there have been laboratory studies, but I could find no evidence that safety or effectiveness have been tested in humans. Hundreds of people have claimed that their remedies can treat all cancers, distinguish between cancerous and noncancerous tissue, and work without side effects. Such claims should not be regarded as credible because (a) cancers vary so much that there is very little hope of finding a simple "magic bullet" that is effective against all types and (b) all substances potent enough to exert therapeutic effects will be potent enough to have side effects. It's also significant that even though CH-23/antimalignocyt has been around for 50 years, no credible evidence of effectiveness has been published.
