Hi Xenyen!
I got all the stuff from amazon and ebay (uk, because i am in europe and shipping costs from the us are way too much) although some stuff ordered directly from the us. I did read here a while ago that if you want a tincture, the best is if you buy the handmade ones. Those are much stronger and better in quality. I have read a tip, to find it on etsy so i ordered a black green walnut tincture from someone who makes them at home.
I spent a lot of time reading through the offers and the ingredients. I spent lots of money too, but i hope it will be worth it. I wish you the best!
