I hate to hear this, but some folk’s favorite remedy for MRSA/Staph boils – tea tree oil (aka melaleuca oil) – has been proven to cause antibiotic resistance. What this means for you is that if tea tree oil has been doing a bang up job healing your infections, it won’t last forever. Your infections will get worse. This problem of bacteria changing so it is unaffected by the current things that kill it is the basis of antibiotic resistance, and we should be very careful to avoid doing things that make bacteria stronger. From what I understand, the minute quantities of tea tree oil in products like shampoos and other bath and body products can contribute as well, so if you are a faithful user of one of these products, you should probably consider switching to something else. I bet Melaleuca is not thrilled to hear this news. Neither am I.
