Natural Care medical cannabis cannabinoids THC CBD licensed producers (or dispensaries, for that matter), CBC is one of the most abundant cannabinoids. CBN is a byproduct of THC, produced as THC oxidizes or, in other words, gets old. Our bodies are naturally inclined to respond to cannabis.

The effect of the compounds on the elevation of intracellular calcium was measured by fluorescence as described in Methods and was assessed in HEK cells stably overexpressing the rat recombinant TRPV2 channel, and as a control, in wild-type HEK cells. Compounds were given to cells 5 min prior to LPC. The effect of the compounds on MAGL was studied in cytoplasmatic fractions of COS cells by using [ 3 H]AG as a substrate, as we had previously reported that the enzyme was abundantly expressed in this preparation Bisogno et al.
The effects are shown in Table 7. The extent and duration of AEA actions are determined by its extracellular concentration, controlled in turn by the rate of AEA synthesis and degradation.
As the hydrolytic enzymes are intracellularly located, an efficient transport system allowing for the rapid trafficking of AEA through these topographically separated sites was proposed. Eleven were found to be active Table 9 , and interestingly none of the most potent preparations inhibited FAAH Table 7. Our current findings extend the concept that some TRP channels may serve as ionotropic cannabinoid receptors, which, in the context of primary afferent nerve fibres, may contribute to inflammatory hypersensitivity or vasodilatation.
These results were not completely unexpected, because we had found previously that some cannabinoids activate TRPV1 Ligresti et al. However, here we investigated for the first time the activity at these four targets of all pure plant cannabinoids, and of all Cannabis BDS, available to date, thus allowing an initial structure—activity relationship study of the effects of these natural compounds at TRP channels, and a direct comparison with extracts that can be easily obtained from Cannabis strains specifically bred to produce one principal cannabinoid over the others.
A limitation of our study is that we did not investigate the effects of the compounds on native cells expressing the TRP channels, such as, for example, sensory neurones from dorsal root or trigeminal ganglia, which are likely to possess a level of cellular structure and subcellular organization with respect to TRP channel localization different from that of HEK cells. Furthermore, we did not assess, for example by using patch clamp techniques, whether or not the effects of the compounds are exerted directly on the channels.
However, it must be remembered that all effects at TRP channels reported so far for plant and synthetic cannabinoids were shown to occur also in dorsal root ganglia neurones Jordt et al.
Therefore, we have no reason to believe that the effects reported here are also not direct and do not occur in sensory neurones constitutively expressing the corresponding TRP channels.
On the other hand, evidence has been obtained against cannabinoid interaction with TRP channels in cells with a level of expression of native TRP channels lower than in sensory neurones Massi et al. In fact, as only those compounds that activated TRPV1 or TRPV2 or TRPA1 per se also antagonized the action of capsaicin or LPC or allyl isothiocyanates, respectively, it is unlikely that these effects were due to antagonism, as in the case of TRPM8, and not to channel desensitization, although clearly the former possibility cannot be completely ruled out.
However, the potency for desensitization for a given cannabinoid was not always proportional to its potency as an agonist per se. Indeed, it is now well established that the ability of TRP agonists to also desensitize these channels depends not only on their potency but also on their lipophilicity and facility to penetrate and cross the plasma membrane Morita et al.
Desensitization might have important consequences for the potential use of cannabinoids as therapeutic agents in those disorders in which these four channels have been shown to be implicated and to play a permissive role, such as chronic and inflammatory pain and cancer.
Importantly, synthetic cannabinoids that activate cannabinoid receptors were also shown to exert antinociceptive effects partly via TRPA1 desensitization Akopian et al. The use of several cannabinoids as analgesics is also suggested by their inhibitory effects on endocannabinoid inactivation mediated by either FAAH which under certain conditions can also recognize 2-AG as a substrate or AEA cellular reuptake which occurs through an as yet uncharacterized mechanism that also recognizes 2-AG.
Interestingly, several BDS and compounds were shown here to inhibit ACU even in the absence of any effect on FAAH, thus arguing in favour of the possibility that the re-uptake of endocannabinoids does not occur uniquely via FAAH-driven diffusion across the plasma membrane Ligresti et al.
In conclusion, our data support the current concept Izzo et al. The present results also reinforce the suggestion that the latter channels, along with their role as sensors of thermic, inflammatory, mechanical and chemical stimuli, should be regarded as ionotropic cannabinoid receptors Akopian et al.
Finally, independently of their possible therapeutic implications, our present data suggest the use of some cannabinoids as pharmacological tools, especially for the study of those proteins, such as TRPV2 and TRPA1, for which very few selective agonists or antagonists have been reported.
Future studies are needed to characterize those components of the various Cannabis extracts used here that inhibit the inactivation of EC and EC-like compounds, and the nature of their interactions with the effects of pure cannabinoids.

Introduction The plant Cannabis sativa L. FAAH assay The effect of increasing concentrations of the compounds on the enzymatic hydrolysis of [ 14 C]-AEA was studied using membranes prepared from rat brain. Open in a separate window. Discussion The results reported here can be summarized as follows: With all TRP channels tested here, the cannabinoid acids were usually weakly active or inactive, whereas the propyl analogues were usually slightly less active than the corresponding pentyl cannabinoids.
However, in some cases, these extracts were endowed with pharmacological actions of their own at the investigated targets, as in the case of the inhibitory effects observed on MAGL and NAAA, or with a capacity to inhibit AEA uptake, antagonize TRPM8 or activate TRPA1 that was stronger than that of the corresponding pure cannabinoids.

This type of pain is often experienced by patients who suffer from Multiple Sclerosis, Fibromyalgia and Epilepsy. In addition to pain relief CBD has been shown to assist with general feelings of anxiety as well as cannabis-induced anxiety.
Recent research at Temple University has suggested that in CBD may also be a strong preventative for the onset of chemotherapy-induced neuropathy, a side-effect of some of chemotherapy drugs.
If the THC breakdown is inhibited, its effects persist longer. Exciting studies that are currently being conducted at California Pacific Medical Center in San Francisco are demonstrating that specific amounts of THC and CBD injected into breast and brain tumors can eliminate those tumors completely, in 30 days.
