This project is focusing on the effectiveness of certain Traditional Chinese herbs consisting of Huang Lian or Coptis root, Liquorice, Golden seal and ginger on the bacteria known as Helicobacter pylori or more commonly known as H. pylori, the bacteria that most commonly causes stomach ulcers. All of the herbs being used have a history of killing Helicobacter pylori, also many other diseases. Traditional Chinese medicine (also known as TCM) has been around for thousands of years, revolving around the belief of yin and yang and and the five flavors and five energies of food. The five flavors include pungent, sweet, sour, bitter and salty. The five energies include cold, hot, warm, cool and neutral. H. pylori affects more than 40% of the world's population, whether it is harmless, or ulcer inducing. Helicobacter pylori unfortunately is a bio-safety level two pathogen which means it has moderate self and environment risk. Instead of using H. pylori, I will be using a strain of e coli, which is a gram negative bacteria. The effects on one gram negative bacteria is relevant to all gram negative bacterium. The Kirby-Bauer method is being used to test the traditional Chinese herbs by soaking thin paper disks in decoctions of the herbs and putting them on top of a spread plate of e coli. Water based herbal infusions are used due to the fact that most extracts contain alcohol and that might act as the killing factor.
