Does anyone know a strong 'natural' anti-biotic?

My brother is on the verge of losing his leg. He had to have ankle replacement surgury. After having the replacement, he broke the same leg just above the new ankle. They had to put pins in it and he was allergic to the metal and developed an infection. (of course) doctors think they know all. they put him on phara anti-biotics over the last year to no avail.(I'm thinking that he has built up an immunity to them, so, they won't work.) I would like to find a 'natural' anti-biotic for him befor he decides to have his leg removed.
thank you to all who may have an answer to this....

'All' of you have given me wonderful info, so its hard for me to decide whats the best answer. So, I"m leaving that up to you to decide. Thank you - to all of you!.. :D

All of the above and also fresh bee royal jelly. It is a strong anti-biotic and anti-viral. It tastes really bad. Make sure you get the fresh and not the freeze dried. It can be applied topically (if there are sore on the skin surface) and should also be taken internally. The best place to get the freshest available is beeroyalproducts.com. You won't be able to find fresh bee royal jelly in any stores. It won't "keep" long enough. Make sure it remains refrigerated too.
