The common name for this plant is "self heal" It acts by inhibiting the activation of the NF-kB pathway of which NOD2 is a part of. NOD2 mutations are associated with Crohn's disease. There are a few theories on NOD2's role in CD but one is "NOD2 acts as a negative regulator following bacterial stimulation of the cell surface receptor toll-like receptor-2, and that the CD-associated mutations result in a loss of this “brake” on the immune response leading to elevated NFkB" Thought I would share this since I find it very interesting. I actually have some Prunella Vulgaris growing in my yard. I think I will make some tea with it and see how it goes...
