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.

Antimalignocyt is made from 2 herbs - Peony (Paeonia Peregrina Mill) and Common mullein (Verbascum). The medicine heals all types of cancerous diseases by destroying only the cancerous cell without damaging the healthy one. The medicine is 100 % non-toxic whereof the relevant documents for toxicity are issued. Antimalignocyt was clinically tested by the Oncological Institute – Vienna on animals and people and later it was tested in the private clinic of Prodan Hristov. All patients in the clinic were terminally ill, i.e. these were patients who have been through all possible ways of treatment – operation, raying, and chemotherapy. It is this medicine that heals up to 70 % of these severely ill patients.
