About hemp oil

What is CBD oil?

CBD is the abbreviation of Cannabidiol, the scientific name for a substance found in the hemp plant. CBD is one of over 100 different cannabinoids that are formed in the flowers and (to a small extent) in the leaves of the plant.

CBD has no psychoactive effect; you cannot get high or stoned from it. More and more people are choosing the natural effect of CBD to increase their sense of well-being. CBD is not addictive and can be safely taken in high doses (max. 160 mg CBD per day). CBD is a non-toxic substance.

There are numerous studies (> 20,000) on the effects of CBD and new discoveries are still being made.

Experience for yourself what CBD oil can do for you.

What is hemp oil, hemp extract and hemp seed oil?

Hemp oil is the collective name for all types of oil that come from the hemp plant, such as CBD oil and hemp seed oil.

Hemp extract is a concentrated oil and can consist of one or more of the more than 100 different cannabinoids that are formed in the flowers and (to a small extent) in the leaves of the plant. Some examples of cannabinoids are CBD, CBN, THCV and CBC.

Hemp oil can contain one or more cannabinoids. To create the right concentration of hemp oil, a carrier oil is added. We use organic MCT oil for this.

Hemp seed oil is pressed from the seeds of the hemp plant. It contains a rich amount of essential fatty acids, vitamins and minerals.

Has the effect been proven?

The Lab of Plants Night hemp oil and the Zen hemp oil are preclinically tested and carry the Ron. J. Glas quality seal.

Dr. Ir. Ronald J. Glas, also known as “The Einstein of Cannabis,” has dedicated more than three decades to extensive research and meticulous exploration of numerous cannabinoid combinations. His mission: to develop functional cannabinoid formulas designed to alleviate health conditions and accelerate the recovery process.

CBD oil is a widely used dietary supplement. Unfortunately, we are not allowed to provide any information about its health benefits (yet). This is despite the fact that over 20,000 different studies on CBD and other cannabinoids demonstrate its therapeutic properties, and this number continues to grow.

In addition, there are numerous patient testimonials (anecdotal evidence) that do not lie: many people have benefited (had) from CBD and/or other cannabinoids. This anecdotal evidence is often included in various surveys that can be found on scientific websites such as PubMed.

We encourage everyone to do their own research, consult a doctor, and experience what hemp oil can do for your sense of well-being.

Can everyone use it?

It is not recommended to use hemp oil during pregnancy or breastfeeding, as there is still too little research on this. If in doubt, ask your doctor, therapist or pharmacist for advice.

In addition, we advise against using the formulas for high blood pressure. In some cases, hemp extracts affect the effect of medications. Caution is advised when combining hemp oil and blood thinners. These are mainly the Vitamin K antagonists and coumarin derivatives. These are on the market under the names Acenocoumarol and Fenprocoumon (coumarins).

Be careful if you are taking thyroid medication. It can wear off faster. If in doubt, consult your doctor or pharmacist. The hemp oils are intended for use by adults.

Does it get you high/stoned?

No, the THC content (this is the substance that can make you high/stoned) can be considered negligible in the products. Our products meet the legal requirements.

How do you use it?

Dose the number of drops correctly according to the instructions. Drip the oil under the tongue and wait 1 minute before swallowing. To be sure of the correct dosage, you can dose the drops on a teaspoon.

If desired, the dosage can be increased gradually. The dosage is individual and requires time and attention. The amount depends on, among other things, the composition of endocannabinoids in the body, body weight and metabolism and the form of administration.

A comprehensive user manual is included with the shipment.

To fully experience what it does for you, it is best to take the product for several (2 to 3) months in a row.

What is the maximum dosage?

For CBD the standard dosage is 10-100 mg per day. 160 mg per day is
considered the maximum amount of CBD per day. The maximum dosage per
You can find the product type on the product page, on the product itself and in the supplied user information.

When will it work?

Some users notice an immediate effect on their well-being. The advice
is to give the product a few months to see what it does for you.

Do the products contain substances found naturally in the body?

For many people it comes as a surprise to learn that our own bodies also produce cannabinoids. We all have our own so-called endocannabinoid system (ECS). This is involved in regulating various physiological processes.

The two major endogenous cannabinoids are anandamide and 2-arachidonoylglycerol (2-AG). Anandamide, also called the “bliss molecule,” has mood-enhancing and pain-relieving effects. 2-AG is involved in the regulation of appetite, sleep, and memory.

Increasing evidence suggests that endocannabinoid deficiency or dysfunction of the endocannabinoid system may play a role in the development of several diseases.

Are there any side effects to using hemp oil?

Side effects of hemp oil are rare. Moreover, they are then relatively mild and temporary in nature (for example, a change in appetite, dry mouth or fatigue). Serious side effects have not been demonstrated. Side effects may be related to interactions with medications.

It is important that you use the hemp oils correctly.

This means: start with 1 drop at a time and experience what it does to you. Then you can gradually build up the dosage if desired. You can read extensive instructions in the enclosed user information.

If you experience a side effect, this may be due to the interaction with your medication. Inform your doctor, therapist or pharmacist.

I am a (top) athlete. Can the products be traced in a drug test?

As of January 2018, CBD has been removed from the WADA doping list. This list is the standard for almost all sports. No statements are made about other cannabinoids (such as CBG) for the time being. Fractions of other cannabinoids can occur in CBD oil. With normal use, cannabinoids can still be found in urine for up to about 1 month.

For other athletes, hemp oil can be a welcome addition to their sport for several reasons. For example, a good night's sleep is important for their recovery at night and for sharpness and energy during the day.

Did you know that a number of famous athletes also use CBD oil? For example, the best golfer of all time Tiger Woods, boxer Mike Tyson and multiple Olympic swimmer Michael Phelps are also said to use CBD supplements.

How do I store it?

For optimal preservation, we recommend storing the product in a cool, dark place.

Keep out of reach of children. Avoid storage above 20°C and exposure to UV (sun)light. Do not freeze.

What is full spectrum?

Full spectrum refers to the full range of substances as naturally present in the plant . CBD is just one of over a hundred different cannabinoids found in the hemp plant.

Many people prefer full spectrum oils where all the good parts of the plant work together for an optimal experience, also called the entourage effect. After all, this is how nature intended it.

What is the entourage effect?

Each hemp extract has its own 'profile', with different percentages and ratios of cannabinoids, terpenes and other substances. In addition to these substances having their own beneficial effects, there is synergy: the substances can influence or even enhance each other's effects.

This is called the 'entourage effect', which is why full spectrum products are sometimes preferred over administering CBD alone.

Is hemp oil safe?

Hemp has been used as a medicine in various cultures for thousands of years. It is non-toxic and therefore does not harm our bodies.

The most well-known substance from the hemp plant is CBD (Cannabidiol). CBD has no psychoactive effect (it does not make you high or stoned) and is not addictive. In various studies, even long-term administration of CBD in high doses (1500 mg per day) was well tolerated by people.

On each product page under Use and safety you can read if the product can be combined with your medication (e.g. blood thinners) and your situation (e.g. pregnancy). If in doubt, consult a doctor or pharmacist.

Furthermore, it is important that you use the hemp oil in a correct way for the best experience for your well-being. For this, read the enclosed information carefully.
