Rick Simpson Oil (RSO) – Everything You Need To Know!

Made from medicinal cannabis, RSO has been shown to have many benefits.

Famed for its powerful medicinal benefits, Rick Simpson Oil (RSO) has become a well known phenomenon. This potent and unrefined cannabis oil is credited with curing cancer – a pretty impressive feat. Are you ready to find out more about RSO oil? Wondering whether it could help you with your medical conditions? Read on and learn all you need to know.

What Is Rick Simpson Oil?

So, what is RSO? In basic terms, it’s a powerful cannabis oil produced using an ethanol extraction technique and indica strains. It got its name from the man who first created it – a Canadian engineer called Rick Simpson.

Rick Simpson rose to fame after claiming to have cured skin cancer using his own custom cannabis oil blend. Sometimes known as Phoenix Tears CBD oil or RSO, this type of cannabis oil is linked to a number of medical benefits.

The Rick Simpson Story

So, why did Rick Simpson create RSO?

Basal Cell Carcinoma

Basal Cell Carcinoma is a form of skin cancer which was cured using RSO.

Back in 2003, Rick Simpson was given a diagnosis of a form of skin cancer called basal cell carcinoma. Not long after, he saw a study in the Journal of the National Cancer Institute which interested him. It revealed that THC had been proven to kill cancer cells in an animal study using mice.

Simpson already used medicinal cannabis to treat dizziness and tinnitus. So, he decided that it was worth giving it a try to treat skin cancer too.

He made his own homemade extract, directly applied it onto the affected skin and bandaged it up. After four days, the growths had disappeared.

The Growing Popularity Of Rick Simpson Cannabis Oil

Simpson started to cultivate and grow cannabis himself which he used to perfect his custom blended oil.

Unfortunately, government and health groups continued to ignore his amazing discovery. Undeterred, Simpson began promoting the medical benefits of cannabis himself. He made a documentary which he published on YouTube and penned a book called “The Rick Simpson Story”.He even gave his amazing oil away to those who needed it free of charge. Sadly, he was prevented from doing this for legal reasons in 2009.

How To Make Rick Simpson Oil

Simpson has faced a lot of scepticism and controversy as well as anger from doctors and medical experts. His lack of clinical trials and scientific research has angered  many physicians. Nevertheless, Simpson has many defenders who also claim to have treated their cancer with his oil blend.

Today, Simpson says he can no longer make or supply RSO because it’s still illegal in many places. He also disassociates himself with online vendors claiming to be Rick Simpson Oil suppliers.

Simpson has stated that patients can only be guaranteed to have genuine RSO if they make it themselves. You can find instructions on the Phoenix Tears website.

It’s important to note that making RSO is potentially dangerous. You need to work in a well ventilated area clear of sparks which could cause the fumes to catch fire. Ethanol Extraction is the best method to produce Rick Simpson Oil.

The process to make RSO is fairly simple.

  • Crush the indica cannabis plant material
  • Place it in a bucket
  • Wash it using ethanol,99% isopropyl alcohol or naphtha. (This will dissolve its active compounds)
  • Strain the solution into a different container
  • Wash it again and mix it
  • Strain the solution on last time
  • Transfer it back to the first container
  • Discard all the plant material
  • Filter the solution to remove remaining plant matter
  • Boil the solution to remove the solvent
  • Pour the solution into a pan made from stainless steel
  • Put the solution in a dehydrator (this will remove any remaining solvent)
  • Cool the solution
  • Put it into capsules or a syringe 

While the RSO extraction process is relatively easy, it may still be too complex for some people. It’s no wonder, then, that many people are wondering where to buy Rick Simpson oil.

Can You Smoke RSO Oil?

Are you wondering how to use RSO? Can you dab RSO or smoke it are two common questions.  

Can you smoke RSO oil is a common question asked by potential users.

There are instructions for dosing on the Phoenix Tears website. However, different people need different dosages depending on how strong their RSO is and their medical condition.

Usually, you don’t smoke RSO. There are three common ways to use RSO:

  • It can be rubbed onto the skin as a topical
  • It can be taken sublingually (as drops placed under your tongue)
  • It can be taken orally as a capsule

RSO can be used topically to great effect.

Which Is The Most Effective Method?

All three ways of using Rick Simpson oil are effective. The sublingual method has the most rapid absorption rate, so the effects would be experienced more quickly. The oral capsule takes longer to take effect but the effects last longer. The best method for you depends on your unique needs.

Is There A Difference Between CBD Oil And RSO?

Many people are confused about the differences between CBD oil and RSO.

CBD oil only contains CBD. This is often derived from industrial hemp.

Meanwhile, RSO contains THC in high concentrations – often 20% minimum. It also contains the entire cannabinoid range found in cannabis plants. RSO is made from indica dominant strains and not industrial hemp.

In 2011, Ethan Russo, a researcher and physician found CBD’s medicinal benefits increased when they were used with other cannabinoids. RSO contains around 2-6% CBD but also has a high THC content to help treat cancer. You can see more about the differences between CBD and RSO in this Rick Simpson Oil YouTube video.


Does RSO Get You High?

The simple answer to this question is yes. Rick Simpson Oil is very intoxicating since it contains high concentrations of THC. CBD oil won’t get you high but RSO definitely will.

Is RSO A Full Spectrum Cannabis Oil?

Full Extract Cannabis Oil is not the same as Rick Simpson Oil.

FSCO (full spectrum cannabis oil) is sometimes called FECO oil (full extract cannabis oil). This term is used to refer to cannabis oil products containing the entire bioactive compound range found in cannabis plants.

These compounds include:

  • Phenols
  • Flavonoids
  • Fatty Acids
  • Cannabinoids in their natural acid form
  • Terpenes

The process of RSO extraction can extract all the compounds however heat is necessary to remove the solvent.

The heat will change the cannabinoids into an activated neutral form from their natural acid form. This process is called decarboxylation. It also volatizes the extracted terpenes. This means the oil may lack some of the original bioactive compounds from the plant’s trichome glands.


Butane Honey Oil (BHO) is different to RSO.

One question often asked is whether BHO (butane honey oil) is the same as Rick Simpson Oil. The short answer is no.

The extraction method used to make BHO is a cold one. This means almost no decarboxylation occurs. This makes it different to RSO which can gone through the decarboxylation process. It is this process which is believed to result in cancer-killing properties. Therefore, BHO would need heat in order to have the same effect as RSO.

What Does Rick Simpson Oil Taste Like?

RSO when taken orally has a vegetal taste.

When taking RSO orally, you can expect a vegetal taste with floral notes. Some users find it slightly bitter but this effect can be reduced by consuming it with other foods.

What Can RSO Be Used For?

Rick Simpson Oil reviews have reported that many users have experienced relief when using RSO for several conditions including:

  • Cancer
  • MS
  • Arthritis
  • Infections
  • Asthma
  • Inflammation
  • Insomnia
  • Hypertension
  • Depression

Are There Any Rick Simpson Oil Side Effects?

Apart from causing a high, there are a few other known side effects of using RSO. These include psychological symptoms such as:

  • Anxiety
  • Paranoia
  • Depression
  • Hallucinations
  • Irritability
  • Disorientation

There may also be some physical effects like:

  • Low blood pressure
  • Dizziness
  • Bloodshot eyes
  • Sleeping problems
  • Slow digestion
  • Poor memory
  • Slower reaction times
  • Unsteadiness

These symptoms are usually short lived and disappear in around a month as your body learns to tolerate the oil.

How Much Is Rick Simpson Oil?

There are several websites which claim to sell Rick Simpson oil. However, if you buy from them you can’t be sure that you’re getting the real deal. It may also not have been made safely using organic plant materials or high quality solvents. The extract may not have been properly filtered or the THC:CBD ratio may be wrong. It may even contain no CBD or THC. There aren’t any standards to adhere to, so you could be buying anything. Making your own is therefore best.



There are many promising testimonials to show positive results when using RSO to treat medical conditions. Although none of this research has yet been scientifically proven, lots of users have found relief when using it. It’s important to make sure, however, that if you’re planning to use RSO, you make sure it’s been safely produced. A properly made RSO could have positive health benefits but a poorly produced one could do more harm than good.
