This plant was selectively bred for centuries by settlers. It is sometimes also called "healer's hand" by tribespeople - a nickname it owes to its five major medicinal virtues. Planted in the growing zone or Hydroponics basins. Grow to make herbal medicine.
Sowing healroot requires a minimum growing skill of 8, but any grower can do the harvesting.
As of Alpha 13 (April 6th, 2016), this plant was renamed to Healroot. Its previous name was Xerigium and may be referenced as such in a number of older guides across the internet.
It may be worth walling off your healroot, as wildlife is more than inclined to consume it, hindering your overall herbal medicine production. A herd of Thrumbos (or even a single for that matter) will be destructive to your Healroot farm if left unprotected.
