I am not a doctor in any way. Even with natural medicines it's always best to consult your caregiver :)
MRSA is a dangerous antibiotic resistant staph infection. It's contracted and transmitted in several ways and can be carried by persons with no symptoms or signs.
It's very difficult to recommend anything without knowing a lot more about the individual. Things like age, general health, allergies, illnesses, other medications are all very important and should be considered.
However, If I were treating myself, here's what I would do...
Echinacea taken internally, which can be gotten in capsules at most health food stores, easily grown, harvested and dried or used fresh. Echinacea purpurea (purple coneflower) grows wild in much of the US. never wildcraft on roadsides (very toxic) and never kill what you wildcraft.
All parts are medicinal. It's a good, natural antibiotic that generally works well when things are resistant to mainstream medicines. I would use a heavy dose, at least the maximum advised on the container 4 times a day or a strong tea/infusion of a teaspoon dried herb to 8 ounces of water (steep covered 5 minutes or more) 4 to 6 times a day or what you care provider advises for a full 10 days. Echinacea can be sweetened with honey but never cane sugar. Echinacea should not be taken for more then 10 days in a row and after 10 days it's best to wait 2 weeks before starting again so as not to build up a resistance.
Your care provider will know best :)
Honey, can be used on open wounds and taken internally. I would suggest 2 tablespoons 3 times a day and if using on wounds, added two to three times a day. Bacteria cannot live in honey.
Cleanliness is of the utmost importance, so clean regularly as prescribed by the care providers.
Pau D'Arco taken internally, can also be gotten in capsules or order in bulk. It strengthens the immune system and also kills some bacteria. 1 to 2 capsules a day or as directed, or 1 strong cup of tea per day made from 1 teaspoon dried herb. This can be mixed with the echinacea and sweetened with honey.
You can also often find valuable help and information by talking to pharmacists. Call your local pharmacy and see what they can advise. Never take anyone's word as the absolute truth, We can only say what we believe to be truth, each body is different and may act differently to different medicines, natural or otherwise. Know your own body and take all else as well meaning advice.
I am not a doctor in any way, shape or form.
Please consult your Care Provider before using any herbs or natural medicinals. Anyone can be allergic to anything, if you're unsure it's better not to use it. Double check everything with you Care Provider if you're pregnant or nursing.
Nothing works for everyone and nothing works exactly the same for everyone. Do the research yourself. Don't take any one persons word for anything, no matter how knowledgeable they seem. Doctors with years of experience make mistakes that cost lives. It's your body, (your home, your car, garden, etc etc etc) take responsibility for it.
