Turmeric is a great herb for repairing nerves and healing your whole body. Not only that, but it also takes the effect fluoride has on the body, away.
Myself, my mother, and grandma have all been taking turmeric for months. I buy it a pound at a time.
A good way to take it is in Golden Milk. That's a tablespoon of turmeric, a tablespoon of honey, and milk, heated on the stove. You can also add cinnamon if you like for taste.
I know, personally many people involved in holistic health practices and one of them owns three health stores, which I've worked at in the past.
I also know someone who's lived an organic/raw life for years and knows loads of things about the kind of lifestyle people here live.
