Aloe Emodin & Other Anthraquinones & Anthraquinone-Like Compounds From Plants Virucidal Against Herpes Simplex Viruses
Sydiskis RJ; Owen DG, 1987

Microbiology Abstracts A Industrial and Applied Microbiology - A method is described of treating type 1 or type 2 herpes simplex virus comprising the successive steps of topically applying to the virus-affected areas of a person suffering from said virus, a topically effective amount of an anthraquinone-containing plant extract, said extract obtained from the group consisting of the gel, sap or leaves of Aloe vera, the bark of Rhamnus frangula, the bark of Phramnus purshiana, the leaves of Cassia angustifolia, and the rhizomes of Rheum rhaponticum; and repeating said topical application as required until the desired anti-viral effect is observed.

In 1963 Lorna Lorenzetti et al. found that freshly freeze-dried Aloe vera gel was bacteriostatic against Staphylococcus 209, Staphylococcus pyogenes, and various forms of Salmonella and Shigella bacteria.

Report Of Effect Of Aloe Vera On Certain Micro-Organisms
Sims, Ruth M; Zimmermann ER

Dr. E. R. Zimmermann and Dr. Ruth Sims of Dallas Microb tested Aloe vera for its germicidal potentials against a number of organisms, including one fungal and two viral agents. The viral agents were staphylococcus aureus (the most virulent strain of staph infection), and Strep viridans (a highly pathogenic strain of strep virus). The fungal agent was the now infamous Candida albicans, a monilial fungus that infects the mucous membranes, most notably the mouth, throat and vaginal areas. Additionally, Aloe vera was tested against Corynebacterium xerosis, a parasitic bacteria present in such skin pathologies as seborrhea. The organisms were tested in culture mediums ranging from solutions containing 25% Aloe vera Gel to solutions containing 90% Aloe vera gel. After thorough testing, Sims and Zimmermann offered the following conclusions:

“Incorporation of Aloe vera at a concentration of 70% would appear highly efficient at reducing skin contaminants S. aureus, S. viridans, and C. zerosis. And an even lower concentration (50%) is sufficient to greatly diminish the population of yeast cells (C. albicans).”

The injection (10-15 ml/kg/d, ip x 4), total glycoside (125-225 mg/kg/d, ip x (3-4); 600 mg/kg/d, ig x 3) and crystal III (120 mg/kg/d, ip x 4) of Aloe vera var. chinensis were found to be effective in lowering the elevated sGPT induced by CCl4, thioacetamide and D-aminogalactose in mice or rats. It was also observed that these agents could protect hepatic cells from the CCl4-induced injury. When dogs were given the Aloe injection of 0.1 ml/kg/d x 180, no toxicity was noted. The total effective sGPT-lowering rate of Aloe injection on 38 patients of chronic hepatitis with positive HBsAg was 86.8%.
