When it comes to cannabidiol oil (CBD), the first thing you’ll want to know is where it sits in relation to the words ‘cannabis’, ‘hemp’ and ‘marijuana’. First thing’s first, let’s make the meaning of each term clear.

The ‘hemp’ plant and the ‘marijuana’ plant are both types of cannabis. What makes them completely different is their ingredients – specifically ‘CBD’ and ‘THC’. The ingredient ‘CBD’ (otherwise known as cannabidiol) is a natural extract of the hemp plant that’s non-intoxicating and void of any psychoactive inducing properties. It’s also the ingredient that’s been widely researched in the States for its health benefits. The ingredient ‘THC’, that is plenteous in the marijuana plant, is responsible for the so called ‘high’ that’s associated with cannabis.

Unlike marijuana plants, industrial hemp – despite being a plant from the cannabis family - does not contain detectable levels of the psychoactive substance, THC (tetrahydrocannabinol) and is legal to take. Cannabidiol is increasingly used as an herbal supplement to promote general feelings of well-being.

How does it work?

Cannabidiol oil has direct effects on the brain to reduce pain perception, relieve anxiety and stress, improve sleep and lift mood. The way it does this – though – is utterly natural and extremely clever. CBD enhances the effects of other brain chemicals like serotonin (often described as the happiness hormone) without stimulating the parts of your brain that marijuana would because of its THC contents. Cannabidiol extracts from industrial hemp plants provide health benefits without causing a ‘high’ and are, unequivocally, not addictive.

What can it help with?

CBD is one of the fastest growing well-being supplements in both the US and the UK. As CBD is oil soluble, it is usually mixed with olive oil or hemp oil to aid optimum absorption into the body.

Joint pain: CBD hemp extracts are antioxidant and have anti-inflammatory effects on joints, to help improve pain and stiffness. They also have pain-relieving effects due to their interaction with certain parts of the brain (1).

Anxiety: Cannabidiol helps to reduce muscle tension, restlessness and fatigue. In a study involving people with social anxiety, taking CBD supplements before a public speaking engagement reduced anxiety, muddled thoughts, social discomfort and anticipatory anxiety significantly more than placebo (2). CBD may also help with the anxiety that can occur when stopping smoking.

Panic attacks: Cannabidiol is being investigated as a promising treatment for panic attacks(3), obsessive compulsive disorder and post-traumatic stress disorder.

Sleep: Cannabidiol (CBD) is a popular treatment for insomnia, and promotes refreshing REM sleep to reduced excessive daytime sleepiness. REM sleep means ‘Rapid Eye Movement’ and is essentially the term for when we enter into a deep phase of sleep - when you dream you experience REM sleep.

General well-being: As discussed CBD oil helps to lift mood and promotes general feelings of well-being.

How much should I take?

A typical dose for a High strength CBD oil is 6.4mg per capsule, taken one to three times daily.

A typical dose for a Super Strength CBD oil is 15mg per capsule, taken once or twice daily.

NB Packaging will include the total amount of CBD present in the whole product (eg 192mg, 384mgm 450mg, 900mg) – this is not the dose per capsule.

Available forms

Healthspan’s CBD oil is obtained from industrial hemp plants that are grown in Europe without herbicides or pesticides, purified and independently tested to ensure they are non-GMO and certified to contain trace amounts of psychoactive ingredients such as THC. Just to be clear, trace elements of THC will have no effect on your physical or mental state whatsoever.
