Cannabidiol (CBD) is a non-psychotropic cannabinoid extracted from hemp plants (Cannabis sativa). Unlike THC, it does not alter the state of consciousness or create addiction; its consumption is legal in France as long as the THC level remains below 0.2%. Numerous scientific studies highlight its analgesic and anti-inflammatory properties. For example, a meta-analysis published in the Journal of Experimental Medicine suggests that CBD inhibits certain inflammatory pathways and can alleviate chronic pain. Furthermore, users report a significant reduction in the intensity and frequency of their headaches after a few weeks of regular CBD use.

The endocannabinoid system, which CBD modulates, plays a key role in regulating pain, sleep, mood, and appetite—all of which are often disrupted in people with migraines or tension headaches. According to an in vivo study, CBD administration improves pain tolerance by modulating CB1 and CB2 receptors and decreasing the release of pro-inflammatory neurotransmitters.

To effectively target headaches, oil remains the most bioavailable and easiest to dose form of CBD.
Here are the essential points to get you started:

Sublingual administration : Place a few drops under the tongue and hold them there for 30 to 60 seconds before swallowing. Rapid absorption through the sublingual mucosa allows for a build-up of effects within 15 to 30 minutes, ideal for relieving an incipient headache.

Gradual dosage : Everyone reacts differently. To determine your optimal dose, use a CBD calculator that will take into account your weight, metabolism, and the level of relief you're looking for. Always start with a small amount (e.g., 5 mg of CBD, or about 1 to 2 drops depending on the concentration) and gradually increase until you achieve a satisfactory effect.

Product quality : choose an oil from organic crops, guaranteed to be pesticide-free, heavy metal-free and with a certified cannabinoid/THC ratio.

Storage and taste : Store the oil away from light and heat. If the bitterness bothers you, you can mix the oil into a drink or food, but be aware that the effect will take a little longer to be felt.

In addition to CBD oil, adopting certain habits can more effectively prevent and relieve headaches. Drinking regularly throughout the day—ideally 1.5 to 2 liters of water—avoids dehydration, which is frequently underestimated. Restful sleep, achieved by promoting regular schedules and a favorable environment (darkness, moderate temperature), strengthens resistance to attacks. Stress management through conscious breathing exercises (deep inhalation, holding, and long exhalation) or meditation helps release nervous tension before it crystallizes into pain. Finally, a gentle massage of the scalp and trapezius muscles, possibly accompanied by essential oils (peppermint, fine lavender, rosemary), can act as a quick boost against tension headaches.
