sugary ? I have not used them. . They do sound good in coffee and tee . I have used other leaves in coffee. The leaves your talking about are good for you help cure cancer . The ones im talking about well just make you feel good no real health benefit . I used coca before i would just suck on them all day nice effect sadly there not grown here . That i know of lol .
I've heard kudzu was a great additive for your compost bin, so I would imagine it would make a good tea. But alas, I don't know shit.
