CINNAMIC ALDEHYDE Your patch test result indicates that you have a contact allergy to cinnamic aldehyde. This contact allergy may cause your skin to react when it is exposed to this substance although it may take several days for the symptoms to appear. Typical symptoms include redness, swelling, itching and fluid-filled blisters. Where is cinnamic aldehyde found? Cinnamic aldehyde is the chemical compound that gives cinnamon its flavor and odor. Cinnamic aldehyde occurs naturally in the bark of cinnamon, camphor, and cassia trees. These trees are the natural source of cinnamon, and the essential oil of cinnamon bark is about 90% cinnamic aldehyde. It is used as a flavoring in food items like chewing gum, ice cream, candy, and beverages and in some perfumes of natural, sweet, or fruity scents. Cinnamic aldehyde is also sometimes used as a fungicide and its scent is known to repel animals like cats and dogs. How can you avoid contact with cinnamic aldehyde? Avoid products that list any of the following names in the ingredients: • 2-Propenal, 3-phenyl- • Cinnamic aldehyde • 3-Phenyl-2-propenaldehyde • Cinnamylaldehyde • CAS RN: 104-55-2 • Cinnemaldehyde • Benzylideneacetaldehyde What are some products that may contain cinnamic aldehyde? Corrosion Inhibitor Fungicide: Food Flavoring: • Root Treatment • Beverages Insecticide - Cola - Vermuth Personal Care Products: • Chewing gum • Dental Floss - Ban-Smoke • Mouthwash - Big Red • Oral anaesthetics - Dentyne Fire • Toothpastes - Slim-mint Pet Care Products: • Candy • Hoffman Dog & Cat Repellent • Ice cream • Nilodor Deodorizing Cleaner Concentrate, Original Fragrances (natural, sweet, or fruity scents): • Nilodor Deodorizing Ferret Shampoo • Almond • Nilodor Nilolitter Cat Box Additive • Apricot • Butterscotch For additional information about products that might contain cinnamic aldehyde, go to the Household Product Database online (http:/ householdproducts.nlm.nih.gov) at the United States National Library of Medicine.

However, the mechanism by which capsaicin induces thermoregulatory responses in invertebrates is unknown. Insect thermoreceptors belong to the TRP receptors family, and are known to be activated not only by temperature, but also by other stimuli. In the following study, we evaluated the effects of different ligands that have been shown to activate (allyl isothiocyanate) or inhibit (camphor) heat receptors, as well as, activate (camphor) or inhibit (menthol and thymol) cold receptors in insects. Moreover, we decided to determine the effect of agonist (capsaicin) and antagonist (capsazepine) of mammalian heat receptor on the American cockroach’s thermoregulatory processes. We observed that capsaicin induced the decrease of the head temperature of immobilized cockroaches. Moreover, the examined ligands induced preference for colder environments, when insects were allowed to choose the ambient temperature.

medicines Article The Chemotaxonomy of Common Sage (Salvia officinalis) Based on the Volatile Constituents Jonathan D. Craft, Prabodh Satyal and William N. Setzer * Department of Chemistry, University of Alabama in Huntsville, Huntsville, AL 35899, USA; [email protected] (J.D.C.); [email protected] (P.S.) * Correspondence: [email protected]; Tel.: +1-256-824-6519 Academic Editors: João Rocha and James D. Adams Received: 2 May 2017; Accepted: 26 June 2017; Published: 29 June 2017 Abstract: Background: Common sage (Salvia officinalis) is a popular culinary and medicinal herb. A literature survey has revealed that sage oils can vary widely in their chemical compositions. The purpose of this study was to examine sage essential oil from different sources/origins and to define the possible chemotypes of sage oil. Methods: Three different samples of sage leaf essential oil have been obtained and analyzed by GC-MS and GC-FID. A hierarchical cluster analysis was carried out on 185 sage oil compositions reported in the literature as well as the three samples in this study. Results: The major components of the three sage oils were the oxygenated monoterpenoids α-thujone (17.2–27.4%), 1,8-cineole (11.9–26.9%), and camphor (12.8–21.4%). The cluster analysis revealed five major chemotypes of sage oil, with the most common being a α-thujone > camphor > 1,8-cineole chemotype, of which the three samples in this study belong. The other chemotypes are an α-humulene-rich chemotype, a β-thujone-rich chemotype, a 1,8-cineole/camphor chemotype, and a sclareol/α-thujone chemotype.

Properties and Therapeutic Potential of Transient Receptor Potential Channels with Putative Roles in Adversity: Focus on TRPC5, TRPM2 and TRPA1
724 Current Drug Targets, 2011, 12, 724-736 Properties and Therapeutic Potential of Transient Receptor Potential Channels with Putative Roles in Adversity: Focus on TRPC5, TRPM2 and TRPA1 L.H. Jiang, N. Gamper and D.J. Beech* Institute of Membrane and Systems Biology, Faculty of Biological Sciences, University of Leeds, Leeds, LS2 9JT, UK Abstract: Mammals contain 28 genes encoding Transient Receptor Potential (TRP) proteins. The proteins assemble into cationic channels, often with calcium permeability. Important roles in physiology and disease have emerged and so there is interest in whether the channels might be suitable therapeutic drug targets. Here we review selected members of three subfamilies of mammalian TRP channel (TRPC5, TRPM2 and TRPA1) that show relevance to sensing of adversity by cells and biological systems. Summarized are the cellular and tissue distributions, general properties, endogenous modulators, protein partners, cellular and tissue functions, therapeutic potential, and pharmacology. TRPC5 is stimulated by receptor agonists and other factors that include lipids and metal ions; it heteromultimerises with other TRPC proteins and is involved in cell movement and anxiety control. TRPM2 is activated by hydrogen peroxide; it is implicated in stress-related inflammatory, vascular and neurodegenerative conditions. TRPA1 is stimulated by a wide range of irritants including mustard oil and nicotine but also, controversially, noxious cold and mechanical pressure; it is implicated in pain and inflammatory responses, including in the airways. The channels have in common that they show polymodal stimulation, have activities that are enhanced by redox factors, are permeable to calcium, and are facilitated by elevations of intracellular calcium. Developing inhibitors of the channels could lead to new agents for a variety of conditions: for example, suppressing unwanted tissue remodeling, inflammation, pain and anxiety, and addressing problems relating to asthma and stroke.

Due to its increasing incidence and the poor efficacy of available antifungals, finding novel antifungal molecules is of great importance. Camphor and eucalyptol are bioactive terpenoid plant constituents and their antifungal properties have been explored previously. In this study, we examined their ability to inhibit the growth of different Candida species in suspension and biofilm, to block hyphal transition along with their impact on genes encoding for efflux pumps (CDR1 and CDR2), ergosterol biosynthesis (ERG11), and cytotoxicity to primary liver cells.

June, 2009 All rights reserved www.bioline.org.br/ja Vol. 13(2) 69 - 74 Camphor: risks and benefits of a widely used natural product PAOLO ZUCCARINI 1Department of Crop Biology, Sect. Plant Physiology, University of Pisa, 56127, Pisa, Italy *Corresponding author. E-mail: [email protected]; tel.: +39 349 1298437 ABSTRACT: This study analyzes the main aspects of the non-clinical profile of D-Camphor, a natural product widely used as a common remedy for several symptoms. The pharmacology, pharmacokinetics and toxicity of this substance are analyzed, with regard to all the literature available, in order to assess a risk profile and better understand the positive and negative aspects connected with its use. The general conclusion is that the main risks of camphor as a medicinal product are mainly due to a somehow diffused attitude of considering it as “not a real medicine”, and to its consequent sometimes not sufficiently careful administration. @ JASEM Camphor is a natural product derived from the effective medicine (Gibson et al., 1989). Camphor wood of the camphor laurel (Cinnamomum is today mostly used in the form of inhalants and of camphora L.) trees through steam distillation and camphorated oil, a preparation of 19% or 20% purification by sublimination; the trees used should camphor in a carrier oil, for the home treatment of be at least 50 years old. It also occurs in some other colds (Jochen and Theis, 1995) and as a major related trees in the laurel family, notably Ocotea active ingredient of liniments and balms used as usambarensis Eng., and can also be obtained from topical analgesics (Xu et al., 2005).
