Romulan is an indica marijuana strain made by crossing North American Indica with White Rhino. Named after the alien Star Trek race, this pine-scented strain is revered for its potent and therapeutic qualities. You can expect Romulan to deliver intense, cerebral effects that eventually give way to sedation and relaxation. Medical marijuana patients choose this strain to help treat symptoms related to muscle spasms and nerve damage. Growers say Romulan produces dense, frosty buds and is a popular choice among growers in the Pacific Northwest.
