Thistle

 is a consumable in Fallout 4.

Characteristics
This flower violet flower has sharp edges, and once it is approached, it explodes into a radioactive cloud of dust after a short period. The dust cloud can be in excess of 20 rads, and without any warning sign, unobservant travelers may be caught off guard by the thistle. If collected before it explodes, it provides 10 hit points at the cost of 5 rads. It is also a component of herbal anodynes and antimicrobials.

Locations

 * Thistles can be looted from containers at farm and are an otherwise unfrequent encounter across the world. Plants can be found near eg. Finch Farm and the Red Rocket truck stop.
