One reader who is five months pregnant has been diagnosed with GBS. Any way this can be cleared up naturally? Well, it made the blood boil of one nurse midwife in the USA who says the antibiotic protocol recommended by the CDC is outrageous. GBS are harmless bacteria found in the vagina and cervix, she says, although there have been cases of infants getting infected during birth, and even dying as a result. Instead of antibiotics, try five drops of tea tree oil in the bath.
