What are terpenes? Terpenes in hemp

It is true that we learn more and more about the beneficial effects of the substances contained in cannabis. Yet still few people know where the secret of the characteristic smell, taste and colour of this plant lies. Terpenes, a large class of organic compounds found not only in cannabis, give the plant its unique smell and taste, but recently it has also started to attract scientists’ attention because of their unusual properties and therapeutic applications.

Flavonoids – the hemp’s secret

Flavonoids – the hemp’s secret

As we have already discussed the properties of cannabidiol in both its basic and acidic form and looked into those less popular cannabinoids, now is the time for some less known cannabis ingredients. Apart from terpenes and terpenoids, flavonoids (or bioflavonoids) are the most group of compounds responsible for the properties of CBD hemp oil as well as for enhancing the effects of natural cannabinoids. What are flavonoids, what are their properties and where can we found them? More »

5 most common myths about CBD hemp oil

5 most common myths about CBD hemp oil

In the media buzz surrounding the topic of hemp, it is sometimes difficult to tell the valuable and confirmed information from the hype, fake news and full fledged lies. The sensationalist media are the one to blame here but the over-zealous cannabis aficionados do not make the things easier. As a result, even those more or less familiar with the subject will spread myths and half-truths every now and then. “Medical marijuana”, “cure for cancer”, “psychoactive oils” – half-baked catchphrases fly across the mediasphere like bullets, while innocent CBD hemp oil gets ricochet shot. Therefore, to sort things out at least a bit, we decided to dispel some of the most common myths about CBD hemp oils as much as try to explain where does their popularity stem from. More »

CBD to THC conversion in the gastrointestinal tract – debunking myths

CBD to THC conversion in the gastrointestinal tract – debunking myths

Cannabis and Cannabinoid Research published a paper in response to a biased article sponsored by the pharmaceutical company Zynerba Pharmaceuticals, Inc., a manufacturer of synthetic gel spreads containing synthetic CBD. The article commented on in the said paper suggested that in the stomach CBD is transformed into THC (1). The eponymous stance of “Even High Doses of Oral Cannabidiol Do Not Cause THC-Like Effects in Humans: Comment on Merrick et al.” article (2) was very well backed with research, debunking the myth particularly disturbing for parents of children with epilepsy which is treated with relatively high doses of CBD. The parents’ fears are in fact justified as if CBD-THC conversion actually did take place on a large scale they might be worried about such a mechanism’s consequences in the future. More »

Cannabis paste or oil – what are the differences?

Cannabis paste or oil – what are the differences?

Today’s entry is less reference-heavy but comes with some photos instead. I’m going to discuss cannabis pastes. Let’s start with a definition – what are the pastes? The name most commonly refers to cannabis extracts of solid consistency that differs them from oils which are, of course, liquids. The consistency of the paste comes as a consequence of the presence of various ballast substances in it that lack any biological activity and are therefore so to say superfluous. Said “ballast” substances, such as chlorophyll and waxes, are common in all plants and in many foodstuffs. Moreover, our observations show that waxes hamper the absorption of cannabinoids, so we do not offer paste as dietary supplements – it would not be much different than selling a regular putty.

CBD(A) (in)solubility in water – results of experiment

CBD(A) (in)solubility in water – results of experiment

So-called “hemp teas” have been available to Polish consumer for a long time now. Said “teas” are basically dried green parts of industrial hemp (cannabis sativa sativa). Taking into account the characteristics of industrial strain of cannabis, one cannot help but wonder – does preparing such infusions actually make sense? Since it is well known that cannabinoids are hardly water-soluble, is it possible for those precious ingredients to be extracted into the beverage? Although there is a paper addressing such problem (Arno Hazekamp: Cannabis tea revisited: A systematic evaluation of the cannabinoid composition of cannabis tea), it deals exclusively with THC and as such it won’t satisfy curiosity of the reader concerned specifically with industrial hemp (which, needless to remind, contains only a very low level of THC).

What are flavonoids and how do they work on the body?

Antioxidants and flavonoids are often mentioned in the context of healthy diet and cosmetic products. Most often stressed is these compounds’ capability to eliminate free radicals, thus slowing down the aging process. It’s true, but how exactly does this process work… and what exactly are flavonoids?

Hemp oil – the treasure of the North (1/2)

Hemp oil – the treasure of the North (1/2)

Hemp oil is considered to be the healthiest among oils because its essential unsaturated fatty acids (EFAs) profile is the most similar to the optimal composition for a human body. These acids are referred to as “essential” due to the fact that the body cannot produce them itself and therefore they must be regularly supplied with food. Moreover, the body doesn’t store them as their purpose is not to provide energy like other fats. Instead, they are raw materials for building cellular structures and are precursors for the synthesis of many biochemical substances, including hormones and prostaglandins, essential for the functioning of the organism.
