Hi Terri,
Next to dandelions, chickweed is probably one of the most vital of all the weeds that most folks laugh at. Hard to say how your friend missed having it, maybe it got eradicated along with a lot of other things over the years. Most people don't know its value.
Nope, if I grew up on it, you can bet it's pretty safe! No need to be skeptical about chickweed.
Just enjoy it; it's a good thing.
