How To Use RSO: Different Ways to Dose (Rick Simpson Oil)

👍 Share:

Rick Simpson Oil (RSO) has carved a niche in the cannabis market. Distinct from CBD oil, RSO is typically derived from high-THC strains of cannabis (marijuana), and it's a highly concentrated cannabis oil. It has a thick, dense consistency similar to molasses, often packaged in syringes — not for injection — but for easier dispensing.

If you're feeling a bit lost about where to start with this intense oil, don't worry. We're here to guide you through the process.

You'll learn the different types of Rick Simpson Oil products available and alternative cannabis products that also feature concentrated cannabis extracts made with federally legal hemp plants. For those of you in states where marijuana isn't recreationally legal, this means you can reap the benefits of a potent cannabis oil without a medical cannabis license.

How To Use RSO Oil: The Different Methods

The two main methods of using Rick Simpson Oil (RSO) are topical application and ingesting it.

Traditional Rick Simpson Oil is a highly concentrated form of cannabis oil with a high THC content as well as a range of other cannabinoids, terpenes, and plant components, making it dark in color and thick and sticky in consistency.

While some might consider smoking or dabbing RSO to achieve fast-acting psychoactive effects, it's not the ideal method to experience its benefits. For one, the strong, earthy, and somewhat bitter taste can be pretty off-putting when inhaled. This is in stark contrast to other cannabis products designed explicitly for inhalation, which have a more pleasant flavor profile.

The potential for lung irritation can be a real concern when smoking or dabbing RSO. 

The production process of RSO often involves solvents like isopropyl alcohol or ethanol. While these alcohols are typically evaporated off, residual solvents can remain in the final product, and inhaling these residues can be harmful and irritate the respiratory system.

How To Use RSO Syringes

The most common use of RSO is through syringes.

To use RSO syringes, simply place the syringe under your tongue and squeeze out the RSO oil. Hold it there for 30-90 seconds, then swallow. 

This isn’t your typical medical syringe but rather a tool for precise dosing. RSO syringes allow for accurate measurement, ensuring you get the right amount. You can use RSO syringes for topical application, direct ingestion, or mixing into food.

How To Use RSO Topically

To use RSO topically, you want to dispense a small, controlled amount from the syringe. The precision ensures you apply just enough to cover the affected area without excess and mess-free.

The benefit of topical application is localized treatment without systemic, psychoactive effects, as it doesn't enter the bloodstream. Instead, the active cannabinoids interact with endocannabinoid receptors in the skin to exert their effects.

By applying RSO directly onto the skin, or using cbd cream for pain, it can all be used to target specific areas of discomfort or concern. This method is particularly valued for its potential to provide relief at the application site.

The story of RSO’s creation is deeply tied to its topical use. Rick Simpson allegedly used his homemade cannabis oil on bandages that he then applied to his basal cell carcinoma (skin cancer).

Simpson reported that after a few days of consistent application, the cancerous spots on his skin showed significant healing. This personal experience was the catalyst for his advocacy of cannabis oil, particularly RSO, for medicinal purposes.

The scientific community has never thoroughly investigated or validated the validity of Simpson's claims. Still, his story has nonetheless ignited considerable interest in the potential of medicinal cannabis.

Mixing RSO In Food

Adding RSO into food is another common method of consumption, especially for those who want to avoid its potent taste and make the experience more enjoyable.

RSO is known for its very strong, earthy, and sometimes bitter taste, which can be off-putting when ingested directly.

Adding RSO to certain foods can mask or complement their taste. Stronger flavors, like chocolate, peanut butter, or spices, can help mask the taste of RSO effectively.

If you plan on cooking CBD gummies with RSO, be mindful of the heating temperature. High heat can degrade the cannabinoids, potentially reducing their effectiveness. Therefore, it's best used in low-heat recipes or added to foods after cooking.

Cooking with butter

RSO blends well with fats, making it ideal for integration into recipes that include butter, oil, or other fatty ingredients. This can improve the absorption of cannabinoids in the digestive system.

When starting with RSO in food, begin with a very small amount (the size of a grain of rice), especially if you are unfamiliar with its effects. It can be more potent when ingested, and the effects can take longer to be felt compared to inhalation.

How To Use RSO Capsules

RSO Capsules

Rick Simpson Oil Capsules are convenient for those who prefer not to deal with the extremely potent flavor and measuring out doses.

RSO capsules contain a specific amount of Rick Simpson Oil in each capsule. This pre-measured RSO dosage ensures consistency in consumption, making it easier to monitor and adjust your intake as needed.

Like any other pill, RSO capsules should be swallowed whole with a glass of water. It's important not to chew or open the capsule, as the oil inside is very potent and has an intense flavor.

Taking RSO capsules with food is often recommended, particularly a meal with some fats. This can aid in the absorption of cannabinoids and minimize any potential gastrointestinal discomfort.

How To Use RSO Tincture

Traditionally, cannabis tinctures are made by dissolving a medicinal herb in alcohol. However, modern tinctures now use carrier oil such as hemp seed oil, coconut oil, or MCT oil, which has a milder flavor, making it more palatable and easy to consume.

You can consume RSO as a tincture, which then dilutes the cannabis extract into more manageable doses with faster sublingual administration, which helps to increase the onset of effects by bypassing the digestive system.

However, if you're worried about the psychoactive effects or high of traditional RSO made from marijuana (high THC cannabis plant), you can opt for Neurogan RSO (Real Scandinavian Oil) made from federally legal hemp plants. The name comes from the Neurogan founders who invented this inspired from their Danish roots and extensive knowledge of hemp and extraction processes.

Modern tinctures like the Neurogan RSO tincture (Real Scandinavian Oil) offer a blend of high-potency CBD with THC. These tinctures provide a more approachable and beginner-friendly option. The use of MCT oil, instead of traditional alcohol, allows for a smoother experience and customizable dosing.

How Often To Take RSO

The frequency and timing of taking RSO depends on the individual's needs and their reasons for using RSO. Some people take one large dose internally daily, while others take it multiple times throughout the day.

While cannabinoids are typically safe to take in large doses, some people may be sensitive to high doses, which is why it's recommended to work your way up in dose to allow the endocannabinoid system to adjust.

Types of RSO Available: Understanding Plant Species and Strains

Rick Simpson Oil (RSO) can be derived from various types of cannabis plants, each offering its unique profile of cannabinoids and effects. 

The primary categorizations of cannabis plants are Indica, Sativa, and Hybrid strains, and more recently, RSO made from hemp has also become available. Understanding these variations is crucial for choosing the RSO that best suits your needs.

Indica-Based RSO

  • Characteristics: Indica plants are typically associated with a more relaxing and soothing effect. They’re often chosen for their potential to help with sleep and relaxation.
  • RSO Use: RSO derived from Indica strains may be preferred for nighttime use or people seeking relief from stress and restless nights.

Sativa-Based RSO

  • Characteristics: Sativa plants are known for their energizing effects and potential to enhance alertness and creativity.
  • RSO Use: Sativa-based RSO might be favored for daytime use or for those looking for a more uplifting and invigorating effect.

Hybrid Strains

  • Combination: Hybrid strains are cultivated by combining Indica and Sativa plants to offer a balance of effects. The specific ratio of Indica to Sativa in these hybrids can vary widely.
  • RSO Use: RSO from hybrid strains can provide a more balanced effect, potentially suitable for a broader range of purposes and times of day.

Hemp-Derived RSO

  • High CBD, Low THC: Unlike traditional RSO, which is high in THC, hemp-derived RSO typically contains high levels of CBD and very low levels of THC.
  • Legal Accessibility: Hemp-derived products are more widely legal in places where THC-rich products are still restricted. This makes hemp-derived RSO a more accessible option for those in such areas.
  • RSO Use: This type of RSO is particularly suitable for those who want the potential benefits of CBD without the psychoactive effects of THC. It's often chosen for its purported benefits for relieving discomfort, inflammation support, and stress management.

Considerations in Choosing RSO Type

  1. Desired Effects: Choose a strain in your edible product based on the effects you're seeking. Indica for relaxation vs Sativa for energy, or hybrids for balance, and hemp for high-CBD benefits.
  2. THC Tolerance: Your tolerance and sensitivity to THC should guide your choice. Hemp-derived RSO is an option for those with low THC tolerance or those who wish to avoid psychoactive effects.
  3. Legal Restrictions: Be aware of the legal status of cannabis in your area. Hemp-derived RSO is generally more widely legal compared to THC-rich options.
  4. Medical Guidance: If using RSO for specific health conditions, consider seeking advice from a healthcare professional experienced in cannabis use.

Understanding the types of RSOs available and their benefits helps you make an informed decision that aligns with your personal needs and preferences. Whether you opt for Indica, Sativa, Hybrid, or Hemp-derived RSO, each type offers unique properties and potential benefits.

The Benefits of RSO Oil

There isn't much scientific research conducted on RSO specifically. However, there is a lot to suggest that cannabinoids have therapeutic properties. Although this field of study is still evolving, many users report various benefits from using RSO.

Here's an overview of the commonly cited benefits :

Chronic Pain Management

The high concentration of full spectrum cannabinoids and terpenes plays a significant role in how it may offer therapeutic effects for users, particularly when it comes to pain management and inflammation.

Research has indicated that cannabinoids, including those in RSO, can have anti-inflammatory effects. This property is particularly beneficial in understanding its potential in managing conditions like arthritis, where inflammation is a primary cause of pain and discomfort [1].

The anti-inflammatory action of cannabinoids comes from their interaction with cannabinoid receptors in the body's immune and nervous systems, potentially reducing the release of pro-inflammatory substances and thus alleviating inflammation.

Support Mental Health

Cannabinoids have been a well-studied area in the realm of mental health issues [2].

THC in high potencies can be a bit of a double-edged sword. While some people can enjoy the psychoactive benefits of THC for relaxation and stress relief, too much can cause heightened feelings of anxiousness.

This is where CBD from hemp-derived RSO may offer more predictable and manageable benefits for stress management as it doesn't produce psychoactive effects. However, you can find some RSO formulations that may provide a balance of THC and CBD for a synergistic balance in supporting mental health.

Sleep Support

RSO, mainly when derived from Indica strains, has gained a reputation for its soothing effects. These can be especially beneficial for individuals struggling to get a good night's sleep.

Cannabinoids like THC and CBD have been observed to influence sleep patterns, potentially helping reduce sleep latency (the time it takes to fall asleep) and sleep duration [3].

RSO as Cancer Treatment

Rick Simpson invented this potent oil in mind — tackling cancer. After his own reported positive experience using the oil on his skin cancer, he became a vocal advocate for cannabis' potential in cancer treatment.

There is a glimmer of hope for this in animal studies, hinting that cannabinoids may have some cancer-fighting properties [4]. But we mustn't jump to conclusions and start calling RSO a cancer cure. The studies aren't extensive, and most haven't been done on humans.

Despite the lack of solid evidence, there are cancer patients out there who choose to include high-cannabinoid products like RSO as a part of their cancer treatment routine as it helps to manage the side effects of cancer treatments, like nausea or loss of appetite. It's not about replacing their standard treatments but more about adding something they believe might help.

The Takeaway: How To Use RSO

Rick Simpson Oil could offer a potent & cheaper option compared to high potency oils, and contains richer cannabinoids from the cannabis plant.

For those seeking a legal and high-potency full spectrum extract alternative, RSO or our Real Scandinavian Oil, made from hemp, stands out as an accessible choice in the market, offering the full cannabinoid benefits without the legal concerns associated with high-THC products.

As always, users should approach RSO thoughtfully and consult healthcare professionals, especially when considering it for severe health conditions.
