"The viridian stem of a plant recently in flower, known for its medicinal effects."
Much like honey, yuckwheat stem is one of the common and efficent remedies in Qud. It is always a good idea to harvest these from the yuckwheat if you are able to as it is quite precious, especially if you are on your way to Golgotha.
If you eat one while you are confused you will become unconfused. This ability can help you greatly if you run into some unexpected seekers of the sightless way; it can also be combined with Witchwood Bark for instant healing.
