I wish this had worked for me. It is very sticky and to me smells awful, but I tried it several nights before bed and put on socks. It did not change my hot/cold feet syndrome at all. I gave it to a friend who uses it occasionally for aches and pains. It seems to help them a little bit.
This is my go-to tincture for helping ease stress and anxiety. I know I'll feel space open up within 30 seconds- 1 minute after taking several droppersful. It's great for breaking the mind spiral loop when you can't get your thoughts to slow. I find it especially helpful for sleep, too, when my brain won't shut off. I never travel without. I have a bottle in my bag, one in my medicine cabinet, and one in my studio.
