About this blog

After seeing news articles say there was NO EVIDENCE that essential oils work for Ebola and hearing that the FDA has not approved any oils for any sort of disease, I decided to see what was out there and expose the essential oil industry. Instead, I found a mountain of peer reviewed studies for all kinds of serious diseases saying how well they work, even on Ebola! So, I decided to set up this blog to post a few studies a week to expose the real frauds and show the world what NO EVIDENCE looks like.
If you find value in my service, please donate to the blog since there is a cost to search and post these articles. I have waded through hundreds, if not thousands of difficult peer-reviewed articles to bring you those related to essential oils and ailments. I hope you find what you are looking for. I wish you great health, wealth and happiness!

(TIP: When looking for an article look in the Archive for titles but also use the Search Box because some articles may delay with say cancer in the title but also mention another disease so they may have tags that allow you to find them in the Search Box.)

Thrombosis,(blood clotting) and Ocotea

Volume 55, Issue 1, January 2007, Pages 23–30

Antiplatelet and antithrombotic activities of essential oil from wild Ocotea quixos (Lam.) Kosterm. (Lauraceae) calices from Amazonian Ecuador


Ocotea quixos essential oil was shown to possess significant inhibitory activity of platelet aggregation and clot retraction in rodent plasma. This study is aimed at fully characterizing the antiplatelet activity of the whole essential oil and its main components trans-cinnamaldehyde and methyl cinnamate also in human plasma, at investigating the mechanism underlying such activity and at evaluating the potential antithrombotic activity of subacute treatment of mice with Ocotea essential oil. In vitro Ocotea essential oil and trans-cinnamaldehyde inhibited arachidonic acid-, U46619-, ADP-, phorbol12-myristate13-alcetate-, collagen-induced platelet aggregation and thrombin-induced clot retraction in human and rodent plasma; Ocotea oil and trans-cinnamaldehyde competitively antagonized contractions induced by thromboxane A2 receptor agonist U46619 in rat isolated aortic ring (KB = 18 and 3.2 μg ml−1, respectively). In vivo Ocotea oil, orally administered in a subacute treatment (30–100 mg kg−1 day−1 for 5 days) to mice, prevented acute thrombosis induced by collagen-epinephrine intravenous injection. This antithrombotic activity was not accompanied by pro-haemorragic side effect, as detected by the inactivity in bleeding test, thus showing a favourable safety profile compared to the conventional antiplatelet agent, acetylsalicylic acid. Present findings indicate that Ocotea essential oil possesses potent and safe antithrombotic activity attributable to its antiplatelet and vasorelaxant effects. The main constituent trans-cinnamaldehyde seems to be the primary responsible for this activity through a putative mechanism involving the inhibition of thromboxane A2 receptors.
