Tea tree oil is a good natural Antibiotic that can be absorbed thru the skin, but it has a very powerful smell to it. It also cannot be used on any mucas membranes, cannot get into the mouth, nose or eyes it will burn bad. Maybe it wld be best to get her home and on hospice so you can give her natural remedies. Garlic also is a natural Antibiotic and the coq10 also very good. Hopfully her mind wont be so scrambled once shes off the meds the docs had her on. Also magnolia bark extract is natural Antibiotic but u dont want her taking more herbs than she can handle so introduce one at a time and see how her body reacts to each one. Play alot of gospel music for her to lessen the trauma she has endured and calm her spirit. Amazing grace is a powerful song.
