Wheel of Time- The four Pillars
Medical practitioners are very rare within most cities of the Wheel of Time. Herbalists and women serving as village wisdom’s are far more common. Some common herbs and their uses are listed here feel free to add more.
Dogwort: This plant can be used to treat wounds. Effectively when applied to an open wound they deal 1 point of subdual damage (per application) and in doing so it cleans an sterilizes the wounds granting a +15 circumstance bonus on saves to avoid infection. It also allows the subject to heal 2 additional points of damage with complete rest.
Catfern: When ingested, or mixed into other foods or drinks this will cause the subject to become sickened (with nausea) for 3d4 minutes before vomiting. A successful Fortitude save (DC 14) the victim vomits immediately. Ingesting Catfern also grants a (+5 circumstance bonus on Fortitude against poisons for 1 hour).
Honey and Sulphur: In canon and reality this is used for throat infections only in the game it may be used to cure other infections 1 ounce is enough for most mundane infections (90% chance). Sorfa tincture: Initially this converts 1d6 of damage to subdual damage. A successful Fortitude save (DC14) allows secondary healing 1d3+2 5 minutes later. A side effect is a temporary loss of 1d2 Wisdom.
