A laboratory study found that tea tree EO showed strong activity against uropathogenic E. coli (UPEC)—the primary cause of many urinary tract infections—including strains that readily form biofilms on urinary catheters. At concentrations as low as 0.25%, tea tree oil reduced bacterial growth, significantly inhibited bacterial attachment and biofilm formation on Foley catheters, and altered expression of a gene involved in curli fiber production, a key factor in bacterial adhesion. While these are in vitro findings, they add to the growing evidence that tea tree oil may help disrupt one of the bacteria's most important survival strategies: biofilm formation.

A new preclinical study found that peppermint essential oil formulated as a nanoemulsion significantly reduced Toxoplasma gondii (the parasite responsible for toxoplasmosis), improved survival, lowered parasite burden, and caused direct structural damage to the parasite itself. Even more encouraging, peppermint showed the best balance between effectiveness and safety when compared to lavender (a surprising finding).

While this is a preclinical model, it highlights the remarkable biological activity of essential oils and their potential as future antiparasitic therapies.
