Crushed leaf is okay, you need double your dose simmered for 20 minutes on the hob to get effects I've found. And it's more subtle and less in your face than powder (certainly less effects than the Bali gold from a couple years ago, which was my most recent use of kratom before this crushed leaf). The Thai maeng da has a nice body warming buzz, the white indo maeng da made me more awake and chatty for about an hour
