Can homeopathic medicines help my weak immune system?
I am sorry to hear about your problem about allergy to antibiotics. It is very unusual indeed to be allergic to all classes of antibiotics. Although there is some cross-resistance between, say, penicillin and cephalosporins, this does not usually extend to other groups like the tetracyclines, macrolides, aminoglycosides, folic acid inhibitors, or quinolones. I mention these groups so that you can check whether any of these have yet been tried on you. Unfortunately you do not tell me why your immune system is weak. This means that in the context of this question I am not able to give you specific advice about how you might be able to strengthen it. As far as homoeopathic medicines are concerned, there is no evidence that these can actively combat bacterial infection. I think it is unlikely that they would help, and if you were faced with a severe infection an attempt to rely on homoeopathic medicines could be frankly dangerous. I would not recommend this.
