Yes, that's fine. I know that lots of members use (and so trust?) Mountain Rose Herbs (
www.mountainroseherbs.com/)
As long as you don't sound like you are trying to get member to buy their herbs there. LOL! As Moderator, I like to add in that I receive no compensation in any way- so that there's no questions, but that's not even necessary when you are just discussing which companies are trustworthy. I agree that even the best places can have a bad batch from time to time, although I think the best companies will monitor their tinctures closely enough that 'bad batches' don't usually make it out of the factory.
For me, the tincture that hubby and I made has saved us quite a bit of money! And it really is that easy. I think the hardest part for me was waiting to see how it turned out! We even grew our own oats to make our tincture - it really doesn't take much herb to make a tincture if you can grow your own!
