Jarum tujuh bilah (7 needles) is a plant with edible leaves. Seven leaves are eaten at one sitting for their medicinal value. The plant has very small but sharp spines or prickly needles which sting when accidentally pierced. The sting lasts a long time, and is worse than those from cacti. The Malay people consume the leaves raw to ward off cancer. The leaves are tasteless and a bit slimy but crispy.
