Blue Dream, a potent even blend of sativa and indica, is one of the most popular marijuana strains of all time. So is Purple Kush, a mightily powerful pure indica (the ratio of sativa to indica is unknown). Together they were used to breed Purple Dream, a mild but effective indica-dominant hybrid. Some sources use this name to describe a different strain, a cross of Blue Dream and Granddaddy Purps, but the Purple Kush cross seems to be more popular.The high is cerebral and euphoric with a mood boost and a creative spark. Use Purple Dream to treat anxiety, mood disorders, depression, ADHD, inflammation, migraine headaches, and muscle spasms.
