What is RSO (Rick Simpson Oil) ? Story, Protocol, Recipe and How to

If you have an interest in medical marijuana, then it won’t be long before you hear about RSO which stands for Rick Simpson oil. The legend of this oil has spread far and wide thanks to reports of its wide-ranging medical benefits, but who is Rick Simpson and what is different about the oil made in his name? In this post, we take a look at the answer to these questions and show you how to make your own batch of this wonderful THC rich oil derived from the Cannabis Indica strain.

Who is Rick Simpson?

Rick Simpson was actually brought to fame by accident and good fortune. Back in 1997, long before cannabis was getting the recognition and acceptance that it is now getting both for personal use and medicinal consumption, the now renowned Rick Simpson was working as an engineer in a Canadian hospital. AT the time he was working in a boiler room where he had been tasked with covering asbestos used on the hospital’s pipes with an aerosol glue to prevent its degeneration.
This boiler room was inevitably poorly ventilated and the toxic fumes from applying the glue led him to collapse and hit his head as he fell off his ladder due to a momentary shock to the nervous system. He lay unconscious for a couple of hours but when he awoke was able to drag himself through to the emergency room. He was soon discharged from his hospital sickbed but was soon feeling sick again and had a sharp ringing in his ears which continued for some years.
The medication he received did not seem to work and actually made him feel worse and after seeing a documentary showing the benefits of cannabis he asked if he could try medical marijuana, but was refused. It was at this point that Rick began to self-medicate with cannabis which soon had him feeling better. Because of how much he felt cannabis had helped him, he began to grow his own cannabis and started to make it into an oil to consume it. He also received encouragement from his doctors to continue using this oil although they could not officially endorse this at the time.

Free Cannabis for everyone

Rick didn’t stop just because he felt better. In fact, he recognized that others were probably in the same boat as he was and could also benefit from using his cannabis oil. As he was growing far more than he could use personally he started offering free cannabis for medicinal purposes to people who thought they might benefit from its use. Unfortunately, this kind gestured soon led to him being raided by the police and sued for his kind efforts and he had to move to Amsterdam.
In 2002 Rick noticed a couple of growths on his face and soon discovered that he had skin cancer. Having already benefitted from cannabis once, he looked into it again and found a 1975 study which showed THC and CBD had been shown to slow the growth of lung cancer in mice so thought he would put his oil to the test. He rubbed his oil into some bandages and wrapped them over these growths and, apparently, they soon disappeared from his face.

According to Rick, his cannabis oil had the potential to tackle the symptoms of cancer. However, it is important to take these claims with a considerable amount of caution and understand his personal experience does not indicate any proof and this treatment should never be used instead of other options. Rick’s case is only anecdotal and is much more important to listen to the advice of doctors and pay attention to peer-reviewed research.
Studies to date have had mixed results. Whilst a 2014 study, which was also carried out on mice, found that THC and CBD extracts seemed to improve the effectiveness of radiation therapy used against an aggressive form of brain cancer, a study in human cells found THC increased the growth rates of particular brain and lung cancer cells. More recent clinical studies involving human participants did not shed any light on whether cannabinoids can actually treat or even control cancer, although they were shown to be safe for use in cancer patients.
All this serves to highlight that you should not expect RSO oil to be a magic bullet in terms of being a cure for cancer and the evidence is not there to show it is necessarily beneficial. However, it is certainly worth talking to your doctor about.

What is Rick Simpson Oil?

So now you know about the Rick Simpson story, you are probably wanting to know what is the oil actually made of and how it is different to other cannabis oils. Well, interestingly enough, the recipe itself was first used way back in the 1800s by someone called W.B. O’Shaughnessy. However, since Rick Simpson offered this oil up for free it has subsequently come to be somewhat unofficially patented by him.
The main way that RSO differs from other cannabis oils is in that it contains much higher levels of tetrahydrocannabinol (THC). THC is the part of the cannabis plant that gets users high as it is a psychoactive cannabinoid. The majority of cannabis oils on the market tend to be cannabidiol (CBD) based and usually contain less than 0.3% THC or even 0 THC. Rick Simpson also doesn’t sell his oil but instead encourages others to do it themselves using his method.

What are the potential benefits of RSO?

So we have already shown that the claims regarding cancer need to be taken with caution but what are some of the other claimed benefits? People have claimed RSO also has benefits for a number of ailments including: asthma, arthritis, the immune system, fighting infections, as an anti-inflammatory, high blood pressure, depression, insomnia, and multiple sclerosis. However, you should bear in mind that these claims are also untested and mostly based on anecdotal evidence.

How to make Rick Simpson Oil?

Ingredients and things you will need for this Rick Simpson Oil recipe:

  1. 1lb of Indica Strain cannabis (cured)
  2. 2 gallons of 99% proof isopropyl alcohol
  3. A deep bowl
  4. A 5-gallon mixing bucket
  5. A long handled wooden spoon
  6. Muslin/Cheesecloth
  7. A rice cooker

If you want to know how to make RSO, the first thing you are going to need to get your hands on is some cannabis buds or preferably entire plants. With this in mind, it is perhaps worth noting that if you are thinking of growing your own cannabis plants for this purpose, you should check you don’t live in a state or region where this is prohibited. The process can also be dangerous if not done properly so should only really be done by professionals.
However, essentially, making RSO is very similar to making Cannabutter and other types of cannabis and hemp tinctures. The Rick Simpson protocol requires the use of Indica cannabis strains for the best results. The buds or cannabis plants should be harvested and cured and then stirred and crushed into a bucket containing enough high-proof alcohol to cover your plant matter. This causes the resin and cannabinoids to separate themselves from the buds and plant matter.
Once the mixture has been resting for 3 minutes you can strain it through a cheesecloth or muslin into a separate bowl and return the plant matter to the bucket. At this stage, around 80% of the THC will have been captured. To get as much of the other 20% as possible you repeat the soaking and stirring process and strain the resulting alcohol into your bowl after three or four minutes. You can throw away the plant matter left in the muslin once you have done this the second time.
The next stage brings the rice cooker in to play. A rice cooker is a good choice because when heating the high-proof alcohol you do not want there to be any sparks or flames anywhere near it as it will set on fire pretty dramatically and very easily. Rice cookers also make it easy for you to control the temperature for a long period of time. You will need to make sure your mixture never reaches above 300 degrees Fahrenheit as this will cook off the cannabinoids.
You should keep the rice-cooker heated to between 210 and 230 degrees Fahrenheit which helps your mixture to decarboxylate. However, you should ideally set this up outdoors because this stage in the process is potentially dangerous as when the alcohol evaporates it can explode if the fumes touch the heating surface. Therefore it is a good idea to point a fan directly at the cooker to move the fumes away from the heat source and being outside prevents the damage an explosion could cause.
Decarboxylation removes the alcohol from the mixture, leaving only the desired cannabinoids in its wake. You will be left with a thick and sticky mixture that is black in color, extremely bitter, and highly potent. You should be careful with this as this is the famed RSO. This is powerful stuff so you should be careful with how much you use in a dose.

What strains make the best RSO in 2022

So now you know how to make RSO you are going to want to know what some of the best strains to grow are for you to get cracking with. You already know that Indica plants are the best for Rick Simpson Oil, but there are so many strains within that. Here are some of our favorite Indica, or predominantly Indica, strains that we know work well in cannabis concnetrates and RSO in-particular.

#1 Best Feminized Cannabis Seeds for making RSO: Afghan Kush Special

These excellent seeds produce a cannabis plant that is particularly well suited to making cannabis concentrates and don’t cost an arm and a leg either. This Afghan Kush is high in both THC and CBD with up to 10% CBD content found in some of the plants we have grown from seeds. This is a purely Indica strain too which would make Rick Simpson very happy indeed. As the seeds are feminized you also don’t need to worry about knowing how to spot a male plant.
Other pros of these seeds are that: they can be grown both indoors and out (although you will need plenty of room for them to grow into); they flower nice and fast and will be ready after around 7 or 8 weeks; they are a strain that is perfect for use making into RSO and have been specifically made to be made into cannabis concentrates, and they have a reasonably high yield. The downside of these seeds is that they grow into huge plants and have actually been genetically modified.
