Benefits of herbal antimicrobials for SIBO
One of the benefits of using herbal antimicrobials for SIBO instead of antibiotics is, antimicrobials such as oregano oil also kill candida.
Many people who suffer from SIBO also have a small intestinal fungal overgrowth. If candida is present alongside SIBO, herbal antimicrobials are best as antibiotics do not kill candida.
The use of antibiotics can also provide candida with the opportunity to overgrow since antibiotics also kill many beneficial bacteria that would keep candida in balance.
Antimicrobials for SIBO are used during the “killing phase” of a SIBO protocol. Phase 2 of the SIBO diet is implemented alongside herbal antimicrobials for the best results.
During the killing phase antimicrobials are used for 4-8 weeks. In some situations, antimicrobials may be used longer but keep in mind that antimicrobials are not meant to be used indefinitely.
If SIBO symptoms persist after using antimicrobials it is necessary to retest to see what kind of results were achieved.
It is also crucial to ensure that you identified and addressed the underlying causes of SIBO to prevent relapse. Sorry, healing SIBO isn’t as easy as just taking antimicrobials. The upper digestive system function must be addressed, among other things.
Grab my gut health guide where I teach how to support the primary organs involved in the upper digestive system and symptoms associated with each digestive organ.
Handling die-off reactions from using antimicrobials for SIBO
In some situations, a die-off reaction can occur as a result of taking antimicrobials such as oregano oil for SIBO.
A die-off reaction can be caused by a massive increase in fungal and bacterial toxins from dying bacteria. If a die-off reaction occurs, it is best to consult your practitioner and reduce or stop the use of antimicrobials for a few days.
The liver is easily overwhelmed by endotoxins produced by dying bacteria. When a die-off reaction occurs, it is essential to ensure that the livers detoxification pathways are open.
Binders such as activated charcoal and bentonite clay can be used alongside antimicrobials to help bind and escort toxins out of the body. Activated charcoal and bentonite clay are excellent binders to help prevent SIBO die-off symptoms.
There are several types of effective antimicrobial products used for SIBO. It is best to choose an herbal antimicrobial or mixture containing herbs that are effective for the type of SIBO you have tested positive for.
