- optical propertiesas a glue, typically as a mounting medium for microscope specimens[16][17]due to purified balsam of Peru's transparency andrefractive indexof 1.597 being very close to that of many glasses used in optics[18]
It also can be found in toothpaste, mouthwash, scented tobacco, cleaning products, pesticides, insect repellants, air fresheners and deodorizers, scented candles, and oil paint.[10][19][20]
Allergy
[edit]A number of national and international surveys have identified balsam of Peru as being in the "top five" allergens most commonly causing patch test reactions in people referred to dermatology clinics.[12][21][22]A study in 2001 found that 3.8% of the general population patch tested was allergic to it.[23]Many flavorings and perfumes contain components identical to balsam of Peru.[24]It may cause redness, swelling, itching, and blisters.[25]
People allergic to balsam of Peru or other chemically related substances may experience acontact dermatitisreaction.[8]If they have oral exposure, they may experiencestomatitis(inflammation and soreness of the mouth or tongue), andcheilitis(inflammation, rash, or painful erosion of the lips,oropharyngealmucosa,or angles of their mouth).[8][12][21]If they ingest it, they may experiencepruritusand contact dermatitis in theperianalregion, possibly due to unabsorbed substances in the feces.[12][26]It can cause a flare-up ofhand eczema.[8]Among the other allergic reactions to balsam of Peru are generalized or resistantplantardermatitis,rhinitis,andconjunctivitis,[12][27]In a case study in Switzerland, a woman who was allergic to balsam of Peru was allergic to her boyfriend's semen following intercourse after he drank large amounts of Coca-Cola.[28]

A positivepatch testis used to diagnose an allergy to balsam of Peru.[8][11][26]Positive patch test results indicate that the person may have problems with certain flavorings, medications, and perfumed products.[8]Among foods, the most commonly implicated are spices, citrus, and tomatoes.[30]
People allergic to balsam of Peru may benefit from a diet in which they avoid ingesting foods that contain it.[12]Naturally occurring ingredients may contain substances identical to or very closely related to balsam of Peru, and may cause the same allergic reactions.[7]In some instances, balsam of Peru is listed on the ingredient label of a product by one of its various names, but it may not be required to be listed by its name by mandatory labeling conventions (in fragrances, for example, it may simply be covered by an ingredient listing of "fragrance" ).[7][31][32][33][34]To determine if balsam of Peru is in a product, often doctors have to contact the manufacturer of the products used by the patient.[35]
Before 1977, the main recommended marker forperfume allergywas balsam of Peru, which is still advised. The presence of balsam of Peru in a cosmetic will be denoted by theINCItermMyroxylon pereirae.[9] Because of allergic reactions, since 1982 crude balsam of Peru has been banned by theInternational Fragrance Associationfrom use as a fragrance compound, but extracts and distillates are used up to a maximum level of 0.4% in products, and are not covered by mandatory labeling.[24]
In March 2006, theEuropean Commission,Health and Consumer Protection Directorate-General,Scientific Committee on Consumer Products,issued an opinion on balsam of Peru.[2]It confirmed that crude balsam of Peru should not be used as a fragrance ingredient, because of a wide variety of test results on its sensitizing potential, but that extracts and distillates can be used up to a maximum level of 0.4% in products.[2]
History
[edit]The namebalsam of Peruis amisnomer.[36]In the early period of Spanish invasion in Central and South America, the balsam was collected in Central America and shipped toCallao(the port ofLima) in Peru, then shipped onward to Europe.[36][37][38]It acquired the name of "Peru" because it was shipped via there.[36][37]Its export to Europe was first documented in the seventeenth century in the German pharmacopoeia. Today it is extracted under a handicraft process, and is mainly exported fromEl Salvador.[39]Another balsam,balsam of Tolu,is extracted fromMyroxylon balsamumvar.balsamumin a different way.[5][40]
