, side effects of pharmaceuticals & toxins like heavy metals.
Some chinese & ayurvedic herbs are contaminated with heavy metals so those could be a cause. However, many herbs have been shown to be helpful in treating neuropathy. See www.Caring.Com/articles/peripheral-neuropathy-treating-it-the-natural-way.
