Maeng Da Kratom was created using a technique called grafting, where tissues of different plants are joined together to breed different qualities of each plant into a new strain. In an effort to create a strain which maintains pain relief while mitigating sedative effects so it could be used during work in Indonesia, Maeng Da was born.
The effects of the Thai kratom leaves tend to be less euphoric than the Bali and Malaysia kratom leaves. However, Thai kratom leaves are said to be more energizing. Therefore, it depends on your mood and your wishes which kratom you want to use.
