There are three main color types of Kratom and a pseudo type that is the result of a different curing process of any of the three main types. The types are classified by the coloration of the central vein in the leaf. There are many different strains of each of these three color types, mainly named after the region they are grown. Red Vein: This color is well known for its calming effects as well as relaxation and pain-relief. It gives the feeling of well-being and optimism while relaxing the body. Some use it as a sleep aid to help with insomnia. White Vein: This color is well known as a stimulant and mood enhancer. It is often taken in place of coffee (caffeine) for alertness, concentration, and cheerfulness. Depending on the dosage and tolerance of the individual, it may also give a sedative effect. It is a common practice to mix the white and red veins together to achieve a more balanced boost in energy. Green Vein: This color is well known to be in between the red and white strains. It is a mild energy booster while also a pain relief for pains and discomforts. It is also said that green Kratom is used to aid in social fear, can make you more talkative, friendly, and cheerful. Green veins are known for longer-lasting effects. For more information check out our Kratom strains guide.
