Smilax
This is not medical advice and should not be taken as such. I am posting this for informational and educational purposes only. If in doubt don’t get to know a plant and it’s safety before using it.
There are many plants in the Smilax family in my area which is the eastern part of the United States. The ones I am familiar with are S. Ecirrhata, and S. Tamnoides. S. Tamnoides has briars on them that really hurt when jagged by them. We also have S. Glauca, S. Herbaceous, S. Rotundifolia, S. Pulverulenta, and S. Pseudochina in my area. I have eaten the leaves and like the taste. Many say the young shoots taste like asparagus. I have never eaten the roots but they are edible.
