laurus nobilis/hypersensitivity

Non-occupational contact allergy to Laurus nobilis (laurel) oil is considered rare. Herein, we report a case of allergic contact dermatitis after a massage with a mixture of olive oil and L. nobilis oil. Patch testing showed (+++) reactions to laurel oil and (++) to the mixture of olive oil and

BACKGROUND Laurus nobilis L. (Lauraceae) has been used for folk medicines in the Mediterranean area and Europe to treat various disorders including skin inflammation (dermatitis) and asthma. OBJECTIVE Our aim was to investigate the scientific evaluation of the compounds from Laurus nobilis L. on

Cross-sensitization between two plant allergens, Frullania and Laurus Nobilis (L.), has been demonstrated in Strabourg. A review of the haptens isolated from Frullania outlines the importance of the purification of allergen to ascertain the nature of the causative agent. New results on laurel oil

Two methods, using methylenelactone dimethylamino adducts, were used to remove selectively alpha-methylene gamma-butyrolactones from Laurus nobilis L. extracts. Isolated lactones were identified and "treated" extracts recovered. Two guinea-pig groups were sensitized to crude extracts and "treated"

Allergic contact dermatitis is a common skin disease, which affects approximately 20% of the population. This reaction may present with several clinical manifestations. Erythema multiforme-like allergic contact dermatitis is a rare type of non-eczematous contact dermatitis, which may lead to

This study investigated the inhibitory effects of costunolide isolated from the leaves of Laurus nobilis L. (Lauraceae) on basophil-mediated allergic reactions and interleukin (IL)-5-mediated B cell growth. The effects of costunolide on β-hexosaminidase (a key parameter of degranulation) release and

9 cases of contact sensitivity to Dittrichia viscosa, mainly with an airborne pattern, are described. All patients reacted to the fresh leaf of the plant and to its ethereal extracts at 1 and 0.5% pet., and some of them also to that at 0.1% pet. Positive reactions to Frullania dilatata, Laurus
