Red Thai is named after its red-veined leaves, which are known to contain higher levels of the alkaloids 7-hydroxymitragynine and mitragynine. These alkaloids are believed to be responsible for the sedative and pain-relieving effects that Red Thai is known for.
Red Thai is said to have a relaxing and calming effect, making it a popular choice for people looking for relief from stress, anxiety, and chronic pain. Some people also report using Red Thai for its euphoric and mood-lifting effects.
