When cast on a plant, this cantrip allows
the druid to determine whether or not
consuming that type of vegetation would
endanger his health. Note that even if only
certain parts of the plant (such as the
berries or leaves) were to be dangerous,
the entire plant would register as inedible.
Also, such things as grass or maple leaves,
while normally not eaten, would still be
revealed as edible, since their consumption would cause no actual harm. The
somatic gestures consist of pointing to the
plant to be identified while making a
chewing motion with the mouth.
