Is there a natural remedy for ttp and hus?

Not that I am aware. I do not believe there is a natural remedy for this condition.
Natural Cures. I truly believe if we weren't born with something we can get rid of it. For the most part many of our ailments are secondary to allergic type reactions to leaky gut syndromes. Like hippocrates put it 'all disease starts in the gut'. Starting a good quality probiotic will start in this healing process. Next would be boosting our immune system and balancing are thyroid and stress hormones.
