Of the countless plant species native to Zandalar, retchweed is one of the most common by far. Found throughout Zuldazar and parts of southern Nazmir, this plant is well known for its use as an emetic among the local trolls. Retchweed is traditionally given to Zandalari children who have swallowed a harmful or poisonous substance in order to induce vomiting, hence the name “retchweed”. Despite its curative properties, however, the green plant can be lethal. When dried, powdered, and combined with riverbud root, it becomes a poison deadly to even the hardiest of heroes [Shadows Rising, pg. 23-24, 248 (hardcover edition)].
Retchweed poison is fast-acting and incredibly painful. Within moments of being ingested, it causes rapid desiccation of the body, followed by death [Shadows Rising, pg. 23-24, 248 (hardcover edition)].
As common as retchweed is, one might be surprised to find that its poisonous qualities are a relatively new discovery. Apari, Yazma’s daughter and Queen Talanji’s former friend, created the poison just within the last year [Shadows Rising, pg. 24 (hardcover edition)].
Though the Plaguelands’ native flora has started to regrow in thanks to the combined efforts of the Cenarion Circle and the Argent Crusade, much of the region’s wildlife still suffers from the plague’s influence today [Quest: Zen’kiki, the Druid,Quest: Postponing the Inevitable]. The Plaguewood, located just outside Stratholme, is home to all sorts of blighted vegetation, including a bright red fruit inauspiciously known as the rotberry. While many species of wild berries found on Azeroth are edible, it is probably safe to assume that rotberries are not fit for human consumption [Item: Rotberry].
A Forsaken apothecary once experimented with rotberries – among several other reagents – in search of a counter-plague agent, though it is unclear if he ever succeeded [Quest: Counter-Plague Research].
Dreadshade is a species of lasher known for producing an extract that has highly versatile, albeit potentially deadly, properties [Item: Dreadshade Extract]. Maldraxxi alchemists of the House of Plagues cultivate the plant to use as a reagent in some of their concoctions, many of which are no doubt extremely toxic. That said, dreadshade has other known practical applications. For example, one of the house’s foremost plague devisers planned to use dreadshade extract in a potion that would effectively “preserve” the imbiber [Quest: Plague is Thicker Than Water,Quest: By Any Other Name].
Dreadshade is said to be the carrier of Solanum cerinthe [Quest: By Any Other Name]. What this is, however, is unclear, though the name suggests it is the scientific name for a plant or fruit.
Widely considered one of the most dangerous regions in all of Outland, Zangarmarsh is home to a diverse range of plant life. Though beautiful, much of the fungal swamp’s flora is quite deadly [Illidan, Chapter Three]. One particularly virulent type of fungi native to Zangarmarsh is the burstcap mushroom, which predominantly grows in the western part of the region. True to its name, the burstcap is extremely sensitive and can release a toxic cloud of spores if handled improperly [Quest: Burstcap Mushrooms, Mon!,Item: Burstcap Mushroom].
