What poison did the Abbasids use to poison the Umayyads?

Zahar, a kind of poison primarily used in poisoning fish. http://books.google.com/books?id=aPu3BfGZFZwC&pg=RA1-PA207&lpg=RA1-PA207&dq=abbasids+used+what+kind+of+poison&source=web&ots=ndgDYMrnEa&sig=wWPLDoE4LCbs4IIp5UZsSmQhGfU&hl=en Another poison possibly used would be sumac. Sumac is a generic name for various plants in the family Anacardiaceae. Most sumacs are genus Rhus. Poison ivy, poison oak and poison sumac may be considered genus Rhus, but are often placed in genus Toxicodendron, due to their containing urushiol. The most common of these plants is T. radicans (poison ivy). Poison sumac is usually used to denote T. vernix. Other members of the family are used for tea, wine and medicine, i.e., Rhus typhira (staghorn sumac). http://www.florilegium.org/?http%3A//www.florilegium.org/files/PLANTS/sumac-msg.html Apr 15 08, 10:54 PM

The name sumac stems from the root s.m.k. which derives the words for the English "blush", since the edible sumac is reddish in colour. I often use it in soups to create a gentle sour taste (much better than lemon for this purpose). Apr 16 08, 2:30 AM
