While historical restrictions on cannabis research had hindered its full medicinal exploration, we have seen an exponential rise in studies in recent years. The National Center for Biotechnology Information's database, PubMed.gov, currently houses nearly 25,000 cannabis-referencing studies, many of which are recent. To help you navigate this whirlwind of scientific progress, we've summarized 10 of the most impactful recent medical cannabis studies, each contributing unique insights into the plant's health and wellness benefits.
Cannabis sativa's Anti-microbial Potency
A substantial volume of research has gone into cannabis' anti-microbial capabilities, focusing on both terpenes and phytocannabinoids. An April 2021 study review in Pharmacology Research & Perspectives indicates Cannabis sativa varieties are particularly effective for anti-microbial purposes. Future studies may elucidate how these phytocannabinoids function and augment each other, thus advancing our understanding of how cannabis and its derivatives can tackle bacterial and fungal conditions.
Neuroprotective Properties of CBD
CBD has garnered significant attention for its potential neuroprotective properties. Current research seeks to understand how CBD can delay cognitive decline and extend the life expectancy of individuals with neurodegenerative disorders. Future studies could harness CBD's mechanism of action to develop new treatments for conditions like Alzheimer's disease and other forms of dementia.
Cannabis in Brain Cancer Treatment
A March 2021 review in the International Journal of Phytotherapy and Phytopharmacology studied the potential use of phytocannabinoids in treating glioblastoma multiforme (GBM), an aggressive brain cancer type. The review affirmed phytocannabinoids' anti-cancer properties, but called for larger-scale human trials to enhance scientific knowledge accuracy.
The Placebo Effect
An April 2021 study in Psychopharamacology explored CBD's anti-anxiety effects, demonstrating the need to measure the placebo effect in clinical trials. While CBD may offer anti-anxiety benefits, participants' pre-existing beliefs could skew results in self-reported studies.
Microwave Distillation for Cannabis Extraction
A novel microwave distillation method for cannabis extraction, detailed in a March 2021 publication by Molecular Diversity Preservation International, allows for a terpene and terpenoid-rich extract. As terpenes and terpenoids are believed to offer therapeutic benefits, preserving these compounds could unlock new potential benefits and improve the natural flavor and aroma of cannabis extracts.
Terpene Formulation Tested Against Human Coronavirus strain 229E
A formulation of terpenes, with and without CBD, showed promising antiviral properties against the Human Coronavirus strain 229E. This provides researchers valuable insights into potential therapeutic uses of cannabinoids and terpenes against similar coronaviruses.
Cannabinoid Receptors and Muscle Pain Management
A study in the European Journal of Pharmacology found a significant connection between cannabinoid receptors and muscle pain management. This supports the link between pain management and the body's endocannabinoid system (ECS), and emphasizes the role of the CB1 receptor in pain perception.
Cannabis Consumption and Attention Disorders
Research in the Journal of Studies on Alcohol and Drugs found that daily cannabis consumption could exacerbate ADHD symptoms. Future studies could determine the exact phytocannabinoids responsible for this effect, helping consumers with attention disorders make more informed choices.
The ECS-Autism Spectrum Disorder Connection
A potential link between the ECS and Autism Spectrum Disorder was explored, based on observed ECS functionality alterations in individuals with Autism. This opens the door for further studies to explore how cannabinoid treatment could manage symptoms associated with Autism Spectrum Disorder.
