Pineapple

The pineapple is a herbaceous perennial plant which grows to 1.0 to 1.5 meters (3.3 to 4.9 ft) tall with 30 or more trough-shaped and pointed leaves 30 to 100 centimeters (1.0 to 3.3 ft) long, surrounding a thick stem. The pineapple is an example of a multiple fruit: multiple, helically-arranged flowers along the axis each produce a fleshy fruit that becomes pressed against the fruits of adjacent flowers, forming what appears to be a single fleshy fruit. The root and fruit are either eaten or applied topically as an anti-inflammatory and as a proteolytic agent. It is traditionally used as an antihelminthic agent in the Philippines.
