This information is not what I expected. The flowers and seeds are very tiny, hardly what I'd expect anyone to eat. The plant is very noxious in it's ordor, similar to cat piss. Why would anyone want to use it as incense? I am most interested in any medicinal characteristics it may have. What are the constituents that would make it good for VD?

Ken Fern, Plants for a Future   Fri Feb 22 2008

This plant is a folk remedy that was used by the Cheyenne people in N. America as a treatment for VD. As far as I know it has never been investigated scientifically for its medicinal properties. The Crow and Klamath tribes both used the seed as a food source. They probably harvested it in the traditional way of carrying a wide but shallow container in one hand and a stick in the other, then walking through an area where various different plants were in seed. They would use the stick to beat the plants, knocking the seed into the container. The seed mix would then often be ground into a powder and cooked as a mush. It was also the Crow tribe that burnt the dried plant as an incense during various ceremonies.

Isn't this plant an invasive species?

I found this plant in the Oregon coast range along side of a logging road. I found the scent quite pleasant. Smells similar to marijuana flowers. I had to pick some to take home. The yellow flowers were just starting to poke out. The buds were very full of sticky resin and could smell it on my fingers hours later. I almost want to make tea out of this.
