RSO for Cancer

RSO for Cancer

RSO has been used to fight cancer since the early 2000s. Simpson developed this method of extracting cannabis oil to treat his skin cancer. Following his success, Simpson drew attention from patients who wanted to learn about the benefits of RSO for cancer.

Is RSO Used for Cancer Treatment?

Yes, RSO is quite effective at fighting cancer and helping patients deal with the side effects of cancer treatments. The therapeutic potential of RSO for cancer is due to its rich blend of cannabinoids, terpenes, and flavonoids. Unlike isolated cannabinoids, cannabis extracts like RSO have shown enhanced efficacy in inhibiting tumor growth. RSO can promote overall well-being by affecting the endocannabinoid system.

Does RSO for Cancer Help Side Effects?

Cannabis oils, such as RSO and FECO, have shown great success in keeping oncology patients comfortable. The aggressiveness of traditional pharmaceuticals used to treat cancer can be overwhelming. Cannabis oils are often prescribed for patients to cope with the side effects, particularly malnutrition, nausea, and pain relief. The overwhelming anecdotal evidence from patients for the benefits of cannabis is stoking the acceleration of research in this area.

RSO for Pain Relief

RSO is well-known for its potential analgesic properties, making it a popular choice for individuals seeking relief from painful cancer treatments as well as chronic pain conditions such as arthritis, migraines, and neuropathy. The THC from high-potency RSO and FECO interacts with the body’s endocannabinoid system to potentially reduce pain perception and inflammation, providing natural and effective relief.

For cancer patients struggling with sleep, RSO can be a game-changer. Indica and CBD-rich cannabis oils have sedative properties that can potentially help induce feelings of drowsiness and promote deeper, more restful sleep. However, most RSO is not strain-specific, which makes it difficult to know what effects the cannabis oil will have on your body and energy levels.

RSO for Sleep

FECO oils from trusted sources like King Harvest Wellness are offered in a variety of strains and ratios, including sativa, indica, THC-dominant, CBD-dominant, and balanced 1:1 strains. By incorporating indica-dominant FECO into a bedtime routine, cancer patients can get much-needed rest and wake up feeling refreshed and rejuvenated.

RSO for Appetite Stimulation

RSO has proved beneficial for individuals experiencing appetite loss or nausea due to medical conditions such as cancer or chemotherapy. Cannabis oils can help increase appetite, promote food intake, and prevent weight loss in patients undergoing treatment. By having an appetite stimulant like RSO, cancer patients can maintain their weight, retain their strength, and allow their body to naturally fight cancer.

RSO for RSO for Anxiety

Cannabis oil made with indica strains can help many patients who suffer from anxiety and stress. Unfortunately, many RSO concentrates are not strain-specific. FECO is a preferred cannabis oil to help with specific uses, like reducing anxiety, improving mood, or increasing focus.

How does RSO Fight Cancer?

The endocannabinoid system is involved in many physiological and pathological or “disease state” conditions such as inflammation, diabetes, cardiac dysfunction, and cancer. Medicinal cannabis products, like RSO, produce their therapeutic effects by activating the CB1 and CB2 receptors. THC targets the central nervous system, which is rich in CB1 receptors and CBD targets CB2 receptors, which are concentrated mostly in the cells of the immune system.

Endocannabinoids themselves are endogenous (from inside the body) lipid signaling molecules. Lipids are fatty compounds that play an important role in cancer treatment. One of their cellular functions is to stop the formation and secretion of exosomes, which have been discovered to increase the growth rate of lung cancer cells. This, among other reasons, is why cannabinoids are often cited for their anti-cancer properties. In addition to cannabinoids, cannabis also contains terpenes and flavonoids that have also been observed to perform actions that actively fight tumors.

Specifically, there has been research that shows whole cannabis extracts are much more effective at impairing the survival and growth of cancer cells than pure THC. This suggests that the combination of cannabinoids, terpenes, and flavonoids is what makes cannabis effective at fighting cancer.

Dosing RSO for Cancer Protocol

The Rick Simpson RSO protocol involves a steady dosage increase of RSO or FECO over 90 days. The goal is for patients to consume a total of 60 grams over 90 days.

The steady increase of RSO over time is due to the potency of the oil. After the 30-day build-up phase, patients will consume one gram per day when they use our standard THC FECO. People with particularly high sensitivity to THC may be advised to first try treatment with King Harvest’s CBD-dominant FECO or 1:1 THC/CBD FECO

Most RSO packaging does not tell patients how to properly dose their medicine. However, FECO from respected brands, like King Harvest, has designed their cannabis oil to allow patients to very accurately measure their dosage. Some people may prefer to eyeball the dosage and a grain of rice is normally used as a suitable measure. 

  • Days 1-7: 10mg per day (⅓ grain of rice)
  • Days 8-11: 20mg per day (⅔ grain of rice)
  • Days 12-15: 40mg per day (1 ⅓ grain of rice)
  • Days 16-19: 80mg per day (2 ⅔ grain of rice)
  • Days 20-23: 160mg per day (5 ⅓ grains of rice)
  • Days 24-27: 320mg per day (10 ⅔ grains of rice)
  • Days 28-31: 600mg per day (20 grains of rice)
  • Days 32-90: 1000mg per day (33 ⅓ grains of rice)

Please note that, as with all cannabis products, the dosage will vary on a case-by-case basis. Contact a dosing specialist from King Harvest Wellness to discover exactly what dosage will work best for you.
