* A study at the University of Texas Medical Branch, found that [[genistein]] and tyrophostin (a pharmaceutical drug) individually inhibit the entry of these viruses into the cells, both through interfering with endocytosis (the process by which a cell pulls in a virus) and uncoating proteins (the process by which a virus alters proteins on the surface of the host cell to gain entry). It was also observed that a synergistic effect occurred when genistein and tyrophostin were added together.
* [[Vitamin C]] : According to the late Dr Robert Cathcart, MD, who had extensive experience treating deadly infections with high dose vitamin C, "the Ebola virus kills by way of free radicals which can be neutralized by massive doses of sodium ascorbate intravenously." Indeed, Ebola virus disease -- as is the case with viral hemorrhagic disease in general -- resembles features of acute scurvy, and vitamin C is well known to have a broad range of benefits, including immune-boosting and antiviral properties, with an incredibly high safety margin.
* [[Red Algae]] produce mannose-binding lectins, which allow the algae to protect themselves from invasion by viruses.
* Homeopathic interventions: A study published in 1999 explored the therapeutic potential of a homeopathic preparation of the six-eyed spider venom (Sicarius) at treating symptoms associated with Ebolavirus infection.
* Estradiol: A 2013 analysis, titled "A systematic screen of FDA-approved drugs for inhibitors of biological threat agents," found that estradiol exhibited anti-Ebola virus activity in vitro, indicating the relevance of hormonal factors and perhaps gender in susceptibility to the disease – as well as a possible therapeutic role for estradiol if future clinical research confirms bears these findings out.
