Effectiveness of garlic in fighting bacteria

This experiment was done to find out if garlic is effective in killing bacteria. This will help us understand the effectiveness of home remedies such as the use of natural herbs (including garlic) for medicinal purposes.

Garlic will kill bacteria and prevent its further growth.

Herbs and spices have traditionally been used in cooking as they add flavor to our food. These herbs and spices have also been known tomany cultures for their medicinal properties. The oils that are extracted from these spices and herbs are found to be effective in killing bacteria and viruses.

The antimicrobial substance in garlic is called allicin. Allicin consists of approximately 0.3% - 0.5% of the garlic. To maintain the antibacterial propertiesof garlic, it must be consumed or applied as raw garlic because cooking will destroy the allicin.
Frequent use of antibiotics causes the microbes to develop resistance against the drugs. Studies have shown that garlic has proven its ability to fight against bacteria that has developed resistance to antibiotics. The use of garlic along with other forms medication has been also known to enhance the effectiveness of these drugs.

The materials required for this experiment:
3 agarpetri dishes prepared with blood agar
300ml milk
1 measurement cup (to measure 100ml of milk)
5 pieces garlic ground and juice extracted( approximately 5ml)
3 test tubes
4 syringes
Escherichia coli (E. Coli) specimen
2 tooth picks
1 permanent marker pen

1. For this experiment, the independent variable is the composition of the test specimen. The dependent variable is the growth of the bacteria colony. This is determined by measuring the size of the growth using [continua]
