Are there any herbal therapies for staph infections?

Do not fool around. Staph can be very bad and even kill you. Antimicrobials are essential.
Probably. A better anwer is that there are probably herbal therapies for every possible recognized medical disorder and unrecognized ones also. The problem is that modern antibiotic therapies are the only ones known to have any true effect on curing staph infections. If i had a staph infection, speaking only as a doctor, i'd rather have an antibiotic than herbs.
Can jump to heart. Staph can go to the heart. I work with cardiothoracic surgeons and we have seen plenty of patients with "innocent" staph. You do not want to fool around with this bug.
