BS.tv documentary "Colombian Devil's Breath," criminals in Colombia have extracted scopolamine from the plant and used it as a potent drug that leaves victims unaware of what they are doing but entirely conscious. Scopolamine can be absorbed through the skin and mucous membranes, allowing criminals to simply blow the powder in a person's face. The documentary is filled with scopolamine-related horror stories, including one account of a man moving all of his possessions out of his apartment (and into the hands of his robbers) without remembering any of it.
This extremely common evergreen shrub is one of the most poisonous plants in the world. "If I were a parent and covering every electrical outlet in the home to protect the kids, I would really have to ask myself why I had an oleander plant growing," Stewart says. The leaves, flowers and fruit contain cardiac glycosides, which have therapeutic applications but are likely to send someone into cardiac arrest should he eat part of the plant. Stewart points out that there is a woman in California currently on death row for trying to poison her husband with the plant, and two young boys were found dead after ingesting oleander a few years back. "People tend to be blasé, because the flowers are bright and pretty, sort of candy-colored. But it is a very poisonous plant that will stop your heart."
Stewart describes this garden plant as more painful than poisonous. Mala mujer, which translates to "bad woman," can be found in parts of the southwest and Mexico and is covered with nasty thorns, which could be turned into makeshift barbwire if needed. The real danger, however, comes from the caustic, milky sap that can leak from the plant. The sap, a common feature among many plants in the Euphorbia genus, can cause painful skin irritations and unsightly discoloration. "I've had several people tell me they had euphorbia saps in their eyes," Stewart says. "And they had pretty surprisingly long-term eye damage."
