How to Use a Medical Cannabis RSO Syringe

What is RSO?

RSO or Rick Simpson Oil is a high-THC, whole plant extract that contains cannabinoids, flavonoids, proteins and other compounds from the cannabis plant. Many patients choose RSO for its whole-plant profile, where compounds may interact in a way known as the entourage effect. This theory suggests that when compounds from the plant are combined, they may work holistically to enhance the overall therapeutic experience (André et al., 2024; Russo, 2019).

In several preclinical cancer models, whole-plant cannabis extracts demonstrated stronger anti-tumor effects than single cannabinoids alone (Tomko et al., 2020). Researchers suggest that the additional cannabinoids, terpenes and flavonoids in full-spectrum extracts may complement each other and reinforce their therapeutic potential.

What is an RSO Syringe?

Administered with a blunt-tipped syringe applicator for oral ingestion, an RSO Syringe allows patients to measure and consume Rick Simpson Oil conveniently. Since RSO preserves many of the plant’s natural components, it carries a more complete profile of the strain. The oil itself is thick with an earthy flavor that closely reflects the aroma of the cannabis plant.

How to Use an RSO Syringe

Review the dosing on your RSO Syringe and the dosing guidelines provided by your physician. Consult your physician if you have any questions about your dose or treatment plan. To administer your dose:

1. Open the Box
Press and hold the cutout on the back of the box, then pull out the tray.

2. Warm the Oil
With the cap intact, gently rub the syringe between your hands for about 30 seconds to one minute to warm the oil. You can also submerge the capped syringe in a cup of warm (not hot) water for 20–30 seconds. Dry it before removing the cap.

3. Measure Your Dose
Unscrew the cap from the applicator tip. Slowly press down on the plunger to dispense the oil while watching the graduation marks on the barrel. Each graduation line equals 0.01 mL (about half the size of a small grain of dry rice) and contains between 7 – 9 milligrams of THC. If the oil feels too thick, you can use a toothpick to help remove it from the tip.

4. Take Your Dose
RSO can be placed directly under the tongue and held for 30–90 seconds before swallowing, or it can be added to food such as a cracker, cookie, or apple slice if you prefer to mask its earthy flavor.

Onset time for RSO depends on factors like metabolism, body composition, tolerance and more. RSO is a concentrated cannabis oil, so patients should start at the smallest dose as directed by their physician.
