5-HTP comes from the beans of Griffonia Seed, a vine native to Africa. In African folk medicine, Griffonia Seed is reputed to be an aphrodisiac, as

well as an antibiotic and a remedy for diarrhea, vomiting, and stomachache. Recent research suggests that Griffonia Seed raises serotonin levels in the brain. Serotonin is important in regulating brain chemistry and is especially important in problems such as depression, insomnia, and eating disorders. Theoretically, supplementing with Griffonia Seed can raise serotonin levels and provide relief from depression and insomnia.
