Several clinically-backed botanical agents are highly effective for treating SIBO, often acting as powerful natural alternatives to pharmaceutical antibiotics. The best herbs depend on your specific SIBO gas profile. For hydrogen-dominant SIBO, Berberine-containing herbs (such as Goldenseal or Oregon Grape) are primary choices. Neem is a powerful, broad-spectrum antimicrobial commonly used in combination protocols. For methane-dominant SIBO, Allicin—a highly concentrated extract derived from garlic—is crucial for reducing methane-producing archaea without feeding the bacteria. Oregano oil is also widely used for its potent antibacterial properties and ability to disrupt protective biofilms. These botanical antimicrobials are typically cycled in combinations for 4 to 6 weeks. Learn more about designing a protocol with [herbal antimicrobials SIBO](/herbal-antimicrobials-sibo).
