Day 44: Antimicrobial Protocols for Gut Health (TYOH, July 2021)

Day 44: Antimicrobial Protocols for Gut Health (TYOH, July 2021)

For some of you – simply eating an anti-inflammatory and blood-sugar balancing diet may be enough to heal your gut and free you from digestive issues. Others will need additional digestive support and probiotics. 


If you have more severe digestive issues, you may need to experiment with an antimicrobial protocol, but not everyone needs this. 




You may benefit from an antimicrobial protocol if:


  • You have tried an elimination diet before (no gluten, grains or dairy for at least 30 days) and you have not seen resolution of your digestive symptoms 
  • You feel less than 50% improvement when strictly following an elimination diet for at least 2-4 weeks 
  • You have been diagnosed with SIBO 


You may not need to try an antimicrobial protocol if:


  • You do not suffer from any digestive issues 
  • You feel 50%-100% better with an elimination diet alone or with an elimination diet and digestive support + probiotics


If you are feeling better after 2 weeks on an elimination diet, and are seeing resolution of some of your symptoms, my advice would be to stick with the diet for at least 4 weeks and reassess where you are at that point. 


However, in my experience, I have found some people do not feel any better with a change in diet, or only marginally better. For these people an antimicrobial protocol can help. After completing an antimicrobial protocol these people then get much more positive results from following the elimination diet for a further period of time. 




There are several well-documented anti-microbial herbs/plants. The most commonly used are:


  1. Oregano
  2. Barberry, Goldenseal, or Oregon Grape (containing the antimicrobial compound berberine)
  3. Olive Leaf (containing the antimicrobial compound oleuropein)
  4. Wormwood (also called Artemesia, containing the antimicrobial compound artemisinin) 
  5. Garlic (containing the antimicrobial compound allicin)
  6. Thyme 
  7. Grapefruit Seed Extract


Most good supplement companies have antimicrobial protocols. A selection for you to investigate further is included below.  It would be a good idea to contact the companies producing these products to discuss their protocols further. 




You must consult your GP/healthcare professional before using any of these antimicrobial protocols. 


These protocols are not intended for long-term daily use. Do not use if you are pregnant or nursing, have a kidney or liver condition or are below the age of 18. 


If you have any other medical condition, if you are taking prescription drugs, or are allergic to eggs, or nuts consult your GP/healthcare professional.

Antimicrobial Protocol 2: Renew Life, ParaSmart

  • ParaSmart is a 15-day broad-spectrum antiparasitic, antimicrobial, and antifungal herbal cleansing program. 
  • It contains herbs and extracts that are widely used to remove both visual (nematode) and microscopic (bacterial) parasites from the body. 
  • It also contains antifungal herbs and extracts that are known to eliminate yeast/fungal organisms from the body.





Wormwood Leaf (Artemisia absinthium) 4:1 Extract 600mg, Caprylic Acid 400mg, Garlic Bulb (Allium sativum) 4:1 Extract 400mg, Thyme Leaf (Thymus vulgaris) 4:1 Extract 400mg, Black Walnut Hull Powder (Juglans nigra) 200mg, Clove Bud (Syzygium aromaticum) 200mg, Pippli Seed (Piper longum) 200mg, Quassia Wood (Picrasma excelsa) 4:1 Extract 100mg, Marshmallow Root (Althaea officinalis) 100mg, Orange Peel (Citrus sinensis) 100mg

Take 2 capsules of ParaSmart 1 and 1ml of ParaSmart 2 in the evening on an empty stomach (2-3 hours after eating). Consume both the morning and evening doses with 1 cup of water. Take for 15 days, followed by a 5 day rest period, and then continue for an additional 15 day period as required (additional ParaSmart Kit required).
