VIDEO: More on Yacon
A little more I found on Yacon and the second harvest. http://greenharvest.com.au/Plants/Information/Yacon.html http://www.ehow.com/way_5906976_yacon-planting-directions.html A link discussing renal toxicity related to eating Yacon leaves. I haven’t fully researched it but it states the onset was after prolonged exposure. (eating) May still be edible but check out the article and be careful. http://www.ncbi.nlm.nih.gov/pubmed/20951787
