Unlike the Universal Edibility Test in 7.2, which is for genuine
survival emergencies with unidentified plants, this is a much
gentler practice for everyday foraging — checking how your own
body responds to a plant you already know is generally edible.

Before eating a new plant for the first time, rub a small amount
on the inside of your forearm and wait about fifteen minutes.
Redness, itching, swelling, or a rash means stop here —
this plant may not agree with you, regardless of how
well-tolerated it is for most people.

If the skin test shows nothing concerning, try a small amount —
a few leaves, a small piece — prepared the way you intend to eat it.
Wait several hours, monitoring for any digestive upset,
tingling, swelling, or other unusual reaction.

If you have known allergies to cultivated plants, be aware that
wild relatives in the same family can sometimes trigger similar
reactions. Someone with a birch pollen allergy, for example,
may react to certain other plants in related families.
If you know your existing allergies, it's worth a little research
into related wild species before trying them.

As mentioned in section 1.3, children are more vulnerable and
often more eager. Introduce new foraged foods to children
in small amounts, one at a time, the same way you would
with any new food — and watch more closely than you would for yourself.
