Good morning @rhozolive
Welcome to the community. Interesting drink you present. Could you please include the scientific name of this plant? We are not sure if it is the potato that we generally eat the tuber of or if it is some variety of this. Thank you.
I had indicated the scientific name as Solanum tuberosum
Potato leaves have a high content of solanine, which is a very toxic alkaloid and can cause poisoning in people. You must indicate this in your post, since the consumption of potato leaves, and even potatoes with green rind, can pose a health risk.
