Burdock

Seen as a weed by most farmers, the burdock root, also known as gobo, is a treasured, healthy food in Japan. It is also one of the most-used herbs in my pharmacy to treat many conditions, including asthma, allergies, acne, eczema, and headaches.

Yellow Dock

This plant produces a beautiful, juicy, yellow root that is high in iron and, interestingly, treats both diarrhea and constipation.

Mullein

Every part of this plant–roots, leaves and flowers–is used in herbalism. I love to use the root, in particular, to treat various spinal issues.
