Picked up some of this Yerba Mate yesterday excited to try.. will be preparing momentarily.
I thought it was from Australia like how they always call everyone "mate" but I guess it's mahtay (mäˌtā

, I think I'll still pronounce it Australian tho it's hard not to, will report experience.
Update: Ok so been drinking this off and on all day it really reminds me of green tea in many ways although less...latexish in taste. I made it like a tea in a loose leaf tea cup with strainer catch at the lip, at certain points I did notice an internal warming accompanied by fleeting energetic bursts however very mild and smooth with moments of.. I don't want to call it euphoria since it wasn't that awesome, I guess I'd call it good feels, but they were fleeting - so much so that I wondered if it was placebo although I wasn't expecting much if anything, I experienced this a couple of times though so I do think there's something there, also I consumed a fair amount of this herb, perhaps the brand I got was not very potent maybe it's better consumed fresher, or maybe I was expecting a bit too much from it.
Update #2
2nd day imbibing this beverage and decided to ramp it up by increasing intake, so I decided to use more leaf per cup and only to drink the 1st wash since I found about 85% comes out in the first cup 10% or so 2nd, and after that it's practically water.
Did not experience same effects as before maybe due to a tolerance or maybe it was all in my noodle, I did find it to have a pretty high caffeine content so if you're looking for a coffee alternative this may be for you but for me it was a very dirty stimulation like I experience when I drink too much coffee, and I kind of hate it because it seems caffeine does either next to nothing for me energy wise. or I'm overdosed, all jittery and feel like poop.
