I love raw rhubarb, with a bit of salt. Again, the stalks are perfectly good to eat. I didn't know the leaves were poisonous,. so I did a bit of research and found this site - http://www.rhubarbinfo.com/rhubarb-background.html#TOC2
. It tells teh botanical nature of rhubarb, its history, its differing varieties, and its cousins and look-alikes. It also confirms that the leaves are indeed poisonous, and what susbtance in the leaf is the culprit, and how it affects you if you eat it.
That being said, the edible stalk, and roots, have medicinal value. They are also a vegetable, but work very well in jams, jellies, and pies. Their flavor naturally compliments strawberries and vice-versa. Rhubarb-straberry pie was a favorite of my mother, and is enjoyed by my family as well. Rhubarb can also be made into a sweet and sour sauce to be used with white meats, and pork, and with tempura-coated foods.
It's a hardy, easy to grow veggie that needs only water, and a place with rich soil. It needs little care and spreads profusely.
Hope this helps.
