There are natural supplements that can help keep the symptoms to a minimum, or help achieve remission but not
cure it. Once you have
graves you will always have it, but I highly believe supplements and
diet can lead to long term remissionion, especially if you have a mild case. Research the effects of L-canrnitine, and lemon balm for hyper. The results are pretty good.
As an aside, please don't throw aside conventional medicine, it has it's benefits.
