...the edible parts may relieve headaches


EDIT: upon further research, I may have to retract my prescription unless I find another version to support the edible rhizomes concept. Until such time, please use this as a guide:

Symptoms
If any part of the plant is eaten or chewed, it can cause immediate pain, burning sensation and swelling of the lips, tongue and mouth. A feeling of local numbness may follow. A few deaths have been reported in children who have eaten leaves or roots. The sap can be extremely irritating to the eyes.

Toxicity
category 2, 3

Warning
Seek urgent medical attention if lips or tongue become swollen or if there is difficulty breathing or swallowing.
