Is it safe to eat raw clitoria ternatea (commonly known as asian pigeonwings, blue pea, butterfly pea, blue ternate, blue ternatea) for the first time? is it possible that it will cause stomach problems or trigger allergic reactions in some people?

Safer as a tea: This question is difficult to answer because this flowering plant is used primarily as a tea. It has a long history of folk use. It's claimed to have a wide range of benefits- see https://www.healthbenefitstimes.com/asian-pigeonwings/ for the most comprehensive article I found. I found NO info on eating it raw so I would be cautious. People can be allergic to any plant and it can cause diarrhea.
