Rick Simpson Oil (RSO) is an extract that is beloved among many medical cannabis patients for its therapeutic benefits. RSO is a whole plant extract that was discovered by none other than Rick Simpson himself. The beautiful thing about the medicine is that he created it for himself.

Rick Simpson developed this oil out of necessity after being diagnosed with skin cancer. Cannabis helped him clear up previous conditions, so when he read a study that THC killed cancer cells in mice, he knew he had to try to use medical cannabis treatment.

To treat the cancerous bumps on his arm, Simpson applied topical cannabis oil under a bandage and left it on for four days. After just those four days the cancerous growths had disappeared, and Simpson knew he had to share this treatment with more patients.

Rick Simpson has helped treat more than 5000 patients using RSO despite police continually raiding his home. He’s also dedicated himself to helping others find the capacity to make RSO for themselves or their loved ones.

How to Use Rick Simpson Oil (RSO)?

In the legal cannabis market, patients can generally find RSO at their local recreational or medical cannabis shop. Once they get it, however, many patients are at a loss as to what to do with it. Applying the cannabis extract directly to the skin as Simpson did can work with skin cancer or topical issues. For those who need to take the medicine internally, they should ingest it. Dabbing RSO is not advised.

Patients are instructed to start with a dosage the size of half of a grain of rice three times a day. For patients that are having trouble swallowing, the extract can be placed directly between the gums and the inside of the lip to let it slowly dissolve. The cannabis extract can also be mixed into food and eaten, but it’s bitter and often needs other flavors to mask its taste.

After week one the dose should be doubled every four days until the sixth week of treatment. During weeks five through 12, a patient should be ingesting one gram of RSO daily. The goal is for a patient to ingest 60 grams of RSO over a 90-day period.

  • Whole plant extracts of Cannabis have been around for decades, long before Rick Simpson popularized them with “Run From the Cure”. Rick Simpson did not “develop” hash oil.

  • RSO is a concentrate, not an extract. You can’t make it with butane and isopropyl alcohol is poison and should never be used in the production process. If you plan on making RSO use only organic sungrown source material and organic ethanol.

  • I have Epilepsy and take about a “pea” size portion twice a day. It takes anywhere from 20 minutes all the way up to an hour for it to really dissolve in my mouth. I really want to find another way to take the medication, but obviously, if I put the RSO into empty pill capsules, it’s dissolving differently in my system. I don’t know if you have any advice on this, or even if you could point me in another direction.

    • For the most effective method of RSO Ingestion is when it is bound to a Fat/Sugar to be absorbed in the stomach for fast and complete absorption of the medicine to the liver. I use Organic Extra Virgin Coconut Oil as my binder and Sunflower Lecithin to prevent separation. you will find some great information here I think that will help you,

      you can use Soy Lecithin also but do not recommend it as you will not find an organic variety that is not GMO-free.

      You will find many formula’s out here, you just need to find what works for you.

      Personally, I use 2 teaspoons Coconut Oil and 1200mg of Sunflower Lecithin to 1 gram of RSO. Combine & Heat on low in a double boiler or candle warmer, mixing now and then till everything combines, and fill your caps with a syringe. You can multiply to make as much as needed at a time. this will average out to 12 to 13 – #00 capsules with .075 grams of RSO per cap. use two grams RSO is you need a stronger dosage to make it .15 grams per cap. or fidget with the amount of RSO up or down to get your desired strength.

      Good Luck Stay Healthy
