Simple home extraction of your Kratom Leaves can be done easily and effectively with some water and lemon or lime. Just take a couple of limes and squeeze them in water (25% lime -75% water) soak your Kratom leaves in this for a some time (I do this only 30 minutes) before boiling them.
This will create a more powerful tea due to the citric acid.
Freezing the leaves and a long slow boil method also work well. Success is guaranteed!
