Viburnum opulus (cramp bark) fresh bark tincture

Typically ships next business day. We ship Tuesday through Friday

Strangely, cramp bark has become a hard-to-find herb. One individual was the supplier for nearly the entire United States. He decided he was done, and the market dried up. Luckily, projects are underway to fill the gap. We've planted 50 cramp bark plants and hope to plant many more in the coming years. A tribe in northern Canada has begun a harvesting project as well.

In the meantime, Dr. Yarnell says black haw (Viburnum prunifolium) is a perfect replacement for cramp bark (Viburnum opulus). He would love to rant at us all about how interchangeable they are and that people shouldn't prefer one over the other just because of a catchy common name. I'll spare you that rant. As soon as we can, we'll have cramp bark back for you. Unfortunately, most of the cramp bark currently available on the market is of poor quality. Stick with black haw for now. If you see us carrying cramp bark again, you'll know its supply is in the clear.
