Cornus, dogwood

 Extract added to tobacco for calming and enhancing perception. Bark and leaves are bitter tonic and analgesic, like aspirin. Good for lower GI deficiency/congestion, leaky gut.

From Torey:  Other uses for Dogwood species. Eastern Flowering Dogwood (Cornus florida), was widely used to treat malaria when quinine was unavailable. Pacific Flowering Dogwood (C. nuttallii) has a history of use as a febrifuge during fever outbreaks circa 1830-1834 at the HBC outpost, Fort Vancouver (Washington). 

One of the first medicines I learned about from indigenous elders was Red Osier Dogwood (aka Red Willow) (Cornus stolonifera). I will never forget one of its uses. Coughs, in particular, barking coughs. Barking coughs - Dogwood.
