Hi again. I've been searching online and I'm coming up with quite a few different things. It looks like our local homeopathic store has "Silica Marina" or "Silicea". Then when I look at the herbal stores, they have "Silicea - Silica". I just wanted to check with you to find out exactly what it is that you have. Don't want to get the wrong ones. Did you get yours online? Sorry to be a pain but I'm anxious to give it a try. Thanks so much for your information. It gives us hope!
