Other info. - The
species name means "thick foot" and one look at the big
rhizome of the plant shows that it is aptly named. The rhizome
used to be used, and probably still is, to treat pain and
bronchial troubles. The plant is toxic however and some people
get violent gastric distress from ingesting it. The plant can
cause skin irritation also.
