type of chamomile?
You're right! It is stinking chamomile. It's also known as mayweed chamomile or dogfennel. I haven't been able to find any information regarding medicinal properties. I do know that mayweed chamomile can cause skin irritation in humans, and can cause contact irritation (blisters in mouth, mucous membrane irritation, etc) in livestock.
The University of Nevada has a nice fact sheet on mayweed chamomile that you might find helpful:
