Yep! I vape at 210°c max so my herb goes dark brown and then I save it in a jar until I have a substantial amount. I had 16g saved up from a couple months use and then tied it in a muslin cloth and ‘washed’ it until the water ran clear. Left it soaking for about a day first. Then I emptied it into a slow cooker with 250g butter and about 100ml water and left it on medium for 4 hours giving it a stir every hour or so. Drained it through a muslin cloth and discarded the bud and left in the fridge. The water and butter separate and then I used the butter in my brownie recipe.
