Pedicularis racemosa, Pedicularis densiflora, and Pedicularis bracteosa are collectively recognized as Pedicularis spp. To ensure sustainability and protect wild populations, we rotate between species and harvest exclusively from areas with verified and secure ecological standards, adhering to best practices for ethical wildcrafting.
Due to the plant’s unique hemiparasitic nature, large-scale cultivation of Pedicularis remains a challenge, requiring specific host plants and highly specialized growing conditions. Consequently, the careful and responsible management of wild stands is essential to safeguard these species for both present and future use. Clinical experience has demonstrated that these species can be used interchangeably, allowing flexibility in their application while supporting biodiversity through the rotation of harvest locations and species.
Some populations of Osha in the United States are overharvested and are in vulnerable or imperiled status. Our wildcrafters do not harvest from these sites. If you would like an equivalent alternative to this herb that is local to the Pacific Northwest, consider using its relative Ligusticum grayi (gray's lovage). We use it in all of our formulas as a replacement for Osha. It is equally effective.
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.
The seed of Ammi visnaga is actually a fruit. Products may be labeled as containing either seed or fruit. While the label fruit is technically more accurate, we are moving towards labels that says seed as that is what it is more typically called in commerce.
Folk herbalists, including Michael Moore, have noted that Pacific valerian may be less likely to cause the paradoxical stimulatory effects reported by some individuals with valerian use. This effect is also believed to be less common when using tinctures made from fresh valerian preparations. Drawing on these traditional insights, we craft our tincture using fresh Pacific valerian. It is important to emphasize that the side effect profile of Pacific valerian compared to garden valerian has not been extensively studied in scientific research.
