Binita,
I have used homeopathy for my son - my son has antibodies and for some limited time we did see and increase in time gap between transfusions but the gap diminished over time. Homeopathic doctors tend to continually evolve the medication to adjust for this diminished reaction to the substances and I think that they may be helpful for most people - I think that the antibody in my son's case interferes with the benefits. Our doctor believes that the plant sterols - which are natural steroids may be responsible for some of the effects.
Best of luck,
Sharmin
