Spasticity
n 2026, FECO (Full Extract Cannabis Oil) is a primary candidate for "refractory spasticity"—muscle stiffness and spasms that do not respond to standard treatments like Baclofen or Tizanidine.
The core benefit of FECO over pharmaceutical isolates (like pure CBD oil) is its high concentration of THC, which is the specific cannabinoid responsible for relaxing the "hyper-excitable" nerves that cause muscles to lock.
1. Rebalancing the "Excitation-Inhibition" Scale
In conditions like Multiple Sclerosis, Spinal Cord Injury, or Cerebral Palsy, the brain loses the ability to send "calm down" signals to the muscles, leading to permanent contraction.
Agonizing CB1 Receptors: THC in FECO binds to CB1 receptors located in the spinal cord and motor cortex. This interaction inhibits the release of glutamate (the "go" signal) and increases the flow of GABA (the "stop" signal), effectively "resetting" the muscle tone.
Gylcine Potentiation: 2025 research has shown that full extracts also enhance the activity of strychnine-sensitive glycine receptors, which are crucial for suppressing the exaggerated reflex arcs that cause sudden, painful spasms.
2. Reducing "Velocity-Dependent" Resistance
One of the most frustrating aspects of spasticity is that the faster a limb is moved, the harder the muscle resists.
Smoothing the Movement: FECO helps reduce this resistance, allowing for a better range of motion during physical therapy. In clinical trials updated in early 2026, patients using a 1:1 THC:CBD FECO showed an average reduction of 2.1 to 2.7 points on the Modified Ashworth Scale (MAS), a common measurement of muscle tone.
3. Addressing the "Spasticity-Pain-Sleep" Triangle
Spasticity rarely exists alone; it creates a vicious cycle of pain and insomnia.
Nighttime Rescue: Because FECO is highly concentrated and long-lasting (6–8 hours), a single dose taken at bedtime can prevent nocturnal spasms that wake patients up.
Pain Desensitization: Beyond relaxing the muscle itself, FECO desensitizes the nerves that signal "cramp pain" to the brain, providing a dual-action relief that pills often miss.
FECO vs. Standard Anti-Spastics (2026 Data)
| Feature | Baclofen (Lioresal) | FECO (Full Extract) |
|---|---|---|
| Muscle Weakness | High risk of "jelly legs" (global weakness). | Targets spasticity while preserving functional strength. |
| Tolerance | Rapid; often requires a surgical pump (ITB). | Slower; often managed via "micro-dosing." |
| Side Effects | Nausea, dizziness, mental "fog." | Euphoria, dry mouth, drowsiness. |
| Onset | 1–2 hours. | 30–90 minutes (sublingual). |
2026 Usage Guidelines for Spasticity
The "Grain of Rice" Rule: FECO is extremely potent. Patients are advised to start with a dose no larger than half a grain of short-grain rice.
Sublingual vs. Oral: For faster relief of an active spasm, the oil is held under the tongue. For long-term 24-hour management, it is swallowed with a fat-containing snack (like peanut butter) to increase absorption.
Terpene Focus: Look for FECO containing Myrcene (muscle relaxant) and Beta-Caryophyllene (anti-inflammatory).
