In this article, I will discuss a few herbs that are considered antibacterial.  Some of them are overall antibacterial and some can help specifically with regulating bacteria within the gastrointestinal tract.  Probiotics help to regulate normal bacterial balance within the digestive tract, but sometimes you may need more than that.  Nature has always been aware of this and shows it through the existence of antibacterial herbs.

Antibacterial herbs may also become more important due to the ongoing issue of antibiotic resistance.

Allium cepa (Onion)

  • Antibacterial
  • Anti-inflammatory, helps reduce allergies
  • Targets gastrointestinal bacteria such as in the case of dysentery and ulcers
  • Tones blood vessels, thus being an aid in cardiovascular health

Allium sativa (Garlic)

  • Antibacterial
  • The oil is used in combination with Mullein oil for earaches or ear infections
  • Enhances the immune system
  • Aids in lowering cholesterol
  • Anti-platelet agent (i.e. thins the blood; caution with blood thinners)
  • Dilates blood vessels, which may help to lower blood pressure


  • Effective against many types of bacteria
  • Used for upper respiratory tract infections, especially in those with weakened immunity
  • Good to dose at first sign of infection – I have done this as well on myself and noticed it is quite effective when taken this way at an adequate dose


  • A common ingredient in European toothpaste to fight the bacteria that cause tooth decay
  • Supports immune function both by stimulating production and activity of white blood cells.  It has been used historically to reduce infection and inflammation of the mucous membranes
  • It aids in healing the gut mucosa, improving GALT and Peyer’s patch function
  • Has been used to address respiratory infections, gastrointestinal inflammation and infection

Burdock root

  • Lesser well known as an antibacterial
  • Helps to cleanse the liver and blood

Oregon grape root

  • Alterative – cleanses the blood

I have used various antibacterial and antifungal herbs extensively on my clients with digestive issues and they have seen notable improvements.
