Poroporo (Solanum lacinatum)
Poroporo is my number 1, go to plant for itch. Any form of itch. Any rash. And particularly any combination of the two. I have used it in a balm with excellent results with full body rashes (don't ask) and also little itchy, small, patches of skin. I have also heard talk that it has similar qualities to wild yam. HOWEVER, I have always been taught that it is poisonous and DON'T INGEST (this means don't eat it, drink it or bathe in it!). Please do not say you weren't warned!
