Garlic equal, or superior to, penicillin

Garlic is another natural antibiotic mentioned frequently in the Bible and used as an herb by Egyptian and other healers of antiquity. The antibiotic activity of garlic is considered to be “quite remarkable.” As early as 1858, Louis Pasteur tested the antibacterial properties of garlic and onion and found they killed or stopped the bacterial growth in culture dishes in his laboratory. Despite Pasteur’s findings, as antibiotic activity from mold was discovered by Alexander Fleming in 1922, and then pharmaceutical companies patented and profited from antibiotic drugs, garlic was disregarded and only considered a folk remedy for infections. History has conveniently been written to attribute the discovery of antibiotics to Fleming rather than Pasteur.
Even strongly diluted garlic preparations can kill many forms of bacteria, as well as fungi and viruses. One scientific report shows that fresh-crushed garlic can kill bacteria at a distance of 20 centimeters (about 8 inches) by its vapor alone. Compared on an equal weight basis, penicillin is 50 times stronger than allicin, the active ingredient in garlic. The antibiotic activity of 1 milligram of allicin equals the antibiotic activity of 15 units of penicillin. [Garlic, The Science and Thera-peutic Application, HP Koch, LD Lawson, 2nd edition, William and Williams, Baltimore, 1996] However, garlic kills a wider variety of bugs, and does not induce the problem of antibiotic resistance. Garlic can also be consumed as a preventive against infection, whereas antibiotic drugs can only be prescribed after an infection is diagnosed. Garlic has advantages over, and is safer than, antibiotic drugs. [Garlic, Nature’s Original Remedy, Fulder S, Blackwood J, Healing Arts Press, Roch-ester, Vermont, 1991] 
Some antibiotics work by inhibition of cell-wall degrading enzymes. Garlic was tested against two common antibiotic drugs, tetracycline and streptomycin, and found to be equally effective as drugs at inhibition of growth and enzyme production. [Hindustan Antibiotic Bulletin 37: 44, 1995] 
Aloe vera
Aloe vera, often used topically to help heal wounds, bites and burns, is another potent antibiotic in the digestive tract when consumed orally. [Economic Botany 17: 46, 1963; International Journal Dermatology 30: 679, 1991]
