My mother was walking with a cane for months because of sciatica. An herbalist recommended she take the homeopathic Hypericum. Within 4 days she was able to walk without her cane. And within 1 week was pain free.
My husband also developed Sciatica and I couldn't find the homeopathic Hypericum. So I purchased St John's wort which is also Hypericum and that cured his Sciatica in 3 days. Make sure you take the product for a few weeks as directed on the bottle.
