However, lily of the valley grows from a rootstock whereas ramps grow from an onion like bulb.

Toxin: The toxic compounds are convallatoxin, convallarian, and convallamarin which are cardiac glycosides.
Symptoms: Symptoms following ingestion include general gastrointestinal distress with nausea, vomiting, diarrhea, and weakness. Additionally, there may be bradycardia and hypotension. C. majalis may be mistaken for Allium tricoccum. A. tricoccocum, also known as "ramp", is a wild relative of the leek and is edible.
Treatment: Vomiting should be induced and stomach pumping performed. In some reported cases patients have been given atropine and lidocaine to reverse the slowed heart beat and low blood pressure in addition to the supportive care for the nausea, vomiting, and diarrhea.
