What Is Rick Simpson Oil (RSO)?
Rick Simpson Oil (RSO), also known as Phoenix Tears, is a highly concentrated cannabis oil with a very high THC content. The oil was popularized by Rick Simpson, who developed it as a homemade extract. RSO is thick, dark in color, and intended for oral use or application on the skin or mucous membranes.
RSO is known for its strong effects and is used by some people in a wellness or supportive context. In this article, you’ll learn what RSO is, how it’s made, and why some users prefer this specific form of cannabis extract.
How Is Rick Simpson Oil Made?
Traditional RSO is made by extracting cannabis with a solvent such as ethanol. The plant material is soaked, filtered, and then heated to evaporate the solvent. What remains is a thick, tar-like oil full of cannabinoids.
A quick overview of the process:
- Cannabis is soaked in a solvent.
- The mixture is filtered to remove plant material.
- Heat is applied to evaporate the solvent.
- The remaining oil is stored in a syringe or small container.
Note: Making RSO with solvents involves risks. Professionally produced oil is often a safer choice.
How Do You Use Rick Simpson Oil?
RSO is usually taken orally: a small drop under the tongue or on a piece of food. Because of its strong concentration, most people use very low doses. RSO can also be applied to the skin.
Because RSO is extremely potent, it is mostly used by experienced users or under professional guidance.
When Should You Choose Rick Simpson Oil?
RSO is suitable for users looking for a powerful, full-plant extract. The oil contains a broad spectrum of cannabinoids and terpenes, which some people find appealing.
Choose RSO if you:
- Want high THC content in a compact form.
- Prefer an oil that can be used orally or topically.
- Are interested in a full-extract product with strong effects.
