Red Vein Thai Kratom (also known simply as Red Thai) is one of the many options for red vein strains of Kratom leaves and powder marketed today. This variety is said to be highly relaxing with positive effects on mood and emotional well-being. It is not as energizing as some of the green vein products, but the effects tend to last longer and it produces more of a euphoric, pain relieving effect. While some stores do sell Green Thai Kratom, the majority of Thai Kratom sold today is of a red strain origin. Products that bear the Thai Red Vein name do not necessarily come from Thailand where it is illegal to cultivate and sell Mitragyna Speciosa. Many of these herbs are grown from trees that have been imported to Indonesia, particularly on the island of Borneo. It is important to remember that not all versions of Red Vein Thai Kratom will be the same, but they all should come from a red vein tree if you are purchasing from a reputable supplier.
