Recent studies showed that self-other integration, as indexed by the joint Simon effect (JSE), can be modulated by biasing participants towards particular (integrative vs. exclusive) cognitive-control states. Interestingly, there is evidence suggesting that such control states can be induced by particular odors: stimulating odors (e.g., peppermint aroma) seem to induce a more focused, exclusive...

BACKGROUND AND STUDY AIMS  Topical peppermint oil prevents intestinal spasm, but can cause rebound spasm. Lidocaine hydrochloride, a local anesthetic, may work as an antispasmodic by blocking Na + channels. The aim of this study was to investigate the effect of topical lidocaine on the inhibition of colonic spasm during colonoscopy, compared with peppermint oil. PATIENTS AND METHODS  A random...

Peppermint leaves contain flavonoids, menthofuran, and other phenolic compounds that have antioxidant activity are believed to inhibit collagen degradation in the skin. This study investigated efficacy of a 5% peppermint leaf extract cream increasing transforming growth factor β (TGF-β) expression amount as indicators maintenance male Wistar rats' skin exposed UVB. Method A randomized post-test...

The antimicrobial and antiplasmid activities of essential oils (orange oil, eucalyptus oil, fennel oil, geranium oil, juniper oil, peppermint oil, rosemary oil, purified turpentine oil, thyme oil, Australian tea tree oil) and of menthol, the main component of peppermint oil, were investigated. The antimicrobial activities were determined on the Gram (+) Staphylococcus epidermidis and the Gram (...

The essential oils of peppermint and spearmint are distinguished by the position of oxygenation on the constituent p-menthane monoterpenes. Peppermint produces monoterpenes bearing an oxygen at C3, whereas spearmint produces monoterpenes bearing an oxygen at C6. Branching of the monoterpene biosynthetic pathways in these species is determined by two distinct cytochrome P450s that catalyze the r...

Respiratory and cutaneous adverse reactions to mint can result from several different mechanisms including IgE-mediated hypersensitivity, delayed-type hypersensitivity (contact dermatitis), and nonimmunologic histamine release. Reactions to cross-reacting plants of the Labiatae family, such as oregano and thyme, as well as to the chemical turpentine, may clue the clinician in on the diagnosis o...

Polyphenolic compounds such as eriocitrin, luteolin-7-O-rutinoside, diosmin, hesperidin, narirutin, isorhoifolin, rosmarinic and caffeic acids were identified in an aqueous extract (Ex) obtained from peppermint leaves (Menthae x piperitae folium). The content of polyphenols in Ex was as follows: eriocitrin 38%, luteolin-7-O-rutinoside 3.5%, hesperidin 2.9%, diosmin 0.8%, isorhoifolin 0.6%, nari...

The acaricidal effect of eleven essential oils (Sweet basil, Common juniper, Atlas cedar, Coriander, Blue gum, European silver fir, Common lavender, Lemon, Peppermint, Scots pine, Summer savory) against poultry red mite Dermanyssus gallinae was tested in vitro using the direct contact method, at three different doses: 0.2 mg/cm2, 0.4 mg/cm2 and 0.6 mg/cm2. The results of the study revealed that...

Original Research A comparative evaluation of efficacy of chloroform, xylene, rectified white turpentine oil, eucalyptus oil and peppermint oil as GuttaPercha solvent: An in vitro study. Kumar A, Pandey KR, Mishra A Abstract: Objective: To compare the efficacy of chloroform, xylene, rectified white turpentine oil, eucalyptus oil and peppermint oil as Guttapercha solvent. Material & Methods: The...

Increasing evidence suggests that `aromas have distinctive effects on the allocation of attention in space: Arousing olfactory fragrances (e.g., peppermint) are supposed to induce a more focused state, and calming olfactory fragrances (e.g., lavender) a broader attentional state. Here, we investigate whether odors have similar effects on the allocation of attention in time. Participants perform...
