Comment les terpènes affectent les effets d’une variété de cannabis ?, Aurélien Bernard, Newsweed.fr, 12 mai 2010

Comment les terpènes affectent les effets d’une variété de cannabis ? Publié le 12 mai 2020 NEWSWEED.fr , Par Aurélien BERNARD https://www.newsweed.fr/comment-terpenes-affectent-effets-variete-cannabis/     Lorsqu’on entend le mot terpène, la première idée qui vient à l’esprit est l’odeur d’une plante. La recherche scientifique a pourtant montré que les terpènes remplissent plus qu’une unique fonction sensorielle. Les terpènes produisent ainsi des effets spécifiques sur le corps, qu’ils soient anti-inflammatoires, antibactériens, relaxants ou anxiolytiques. C’est d’ailleurs aussi pour cette raison que certaines variétés procurent un sentiment de calme et de bien-être, alors que d’autres favorisent l’énergie. Les terpènes s’insèrent ainsi complètement dans l’effet d’entourage, qui suppose que les composants [...]

Developing Robust Standardised Analytical Procedures for Cannabinoid Quantification : Laying the Foundations for an Emerging Cannabis-Based Pharmaceutical Industry, Matthew T. Welling et al., 2019

Developing Robust Standardised Analytical Procedures for Cannabinoid Quantification : Laying the Foundations for an Emerging Cannabis-Based Pharmaceutical Industry Matthew T. Welling, Lei Liu, Arno Hazekamp, Ashley Dowell, Graham J. King Medical Cannabis & Cannabinoids, 2019, 2, 1–13 Doi : 10.1159/000496868   Abstract The plant genus Cannabis is a prolific producer of unique pharmaceutically relevant metabolites, commonly referred to as cannabinoids. Robust and standardised methods for the quantification of cannabinoids within botanical and drug forms is a critical step forward for an emerging Cannabis- based pharmaceutical industry, which is poised for rapid expansion. Despite a growing body of analytical methods for the quantification of cannabinoids, few have [...]

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors, David B. Finlay et al., 2020

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors David B. Finlay, Kathleen J. Sircombe, Mhairi Nimick, Callum Jones and Michelle Glass Frontiers in Pharmacology, 2020, Volume 11, Article 359, 1-9. doi : 10.3389/fphar.2020.00359   The entourage effect was a proposed explanation for biological observations that endocannabinoid ligand activities can be modified by other lipids released from cells at the same time. An increasing volume of anecdotal reports and interest in the plant have provoked research into the activity of minor chemical constituents of the plant—including volatile terpenoids such as myrcene, a- and b- pinene, b-caryophyllene, and limonene. However, to [...]
