I bought the Astragalus at the Oriental store and used about 2 oz of the Astragalus. It is like dried sticks. I put them in a pot of filtered water and brought them to a boil then turned down the heat to simmer for several hours. Then I strained off the sticks and kept the broth. Then I added the vegies that are listed but I also included chopped celery. I really liked it. The broth is clear and the combination of flavors are delicious. Highly recommend it.
