Please be very careful while consuming these alternative remedies. I am an Indian and there are alarm bells ringing in the medical science community over unsafe levels of herbal/ayurvedic medicines being consumed by people. There can be adverse effects of such herbs on your kidneys and liver. For me, these remedies don't have an effect on stuttering, it's mostly placebo. I can understand that you're yearning for a remedy, but be careful while trying things out. You don't want to live with a dysfunctional body organ along with stuttering.
