What to Know About RSO

What is RSO?

RSO is short for Rick Simpson Oil. Rick Simpson is a Canadian engineer and cannabis advocate who created a full-spectrum (also known as a whole-plant extract) cannabis oil after a work accident caused a variety of health issues. Full spectrum extract includes all the cannabinoids, flavonoids, terpenes, proteins and other beneficial compounds of the plant.

What type of strain is the RSO?

Our RSO is extracted from our Blue Dream strain, grown locally at our state-leading facility in South Austin. Blue Dream is a sativa dominant hybrid strain. 

How do I administer the medicine?

To administer, push down and unscrew the top, then squeeze the bulb of the dropper. Submerge the entire tip of the dropper into the tincture. Release the bulb to draw the oil into the dropper. Follow dosing marked on the dropper as directed by physician. 

What is the difference between the RSO Tincture and our other tinctures?

Unlike our other tinctures, which are made with distillate, our RSO tincture is made with full spectrum cannabis extract.

What's the difference between distillate and RSO/full spectrum extract? 

Distillate is a refined and purified extract containing only the intended cannabinoids, such as THC or CBD. RSO is a full-spectrum oil containing all the compounds of the cannabis plant including cannabinoids, flavonoids, terpenes and other potentially beneficial compounds.

What does the RSO Tincture taste like?

RSO has a grassy, woody and earthy flavor with slight bitterness. Our RSO Tincture tastes different from our other Unflavored Tinctures because it is made with full spectrum cannabis extract, which contains all the components of the plant.
