Name Potential reaction(s) Remarks
Balsam of Peru Redness, swelling, itching, allergic contact dermatitis reactions, stomatitis (inflammation and soreness of the mouth or tongue), cheilitis (inflammation, rash, or painful erosion of the lips, oropharyngeal mucosa, or angles of their mouth), pruritus, hand eczema, generalized or resistant plantar dermatitis, rhinitis, conjunctivitis, and blisters. Present in many foods, such as coffee, flavored tea, wine, beer, gin, liqueurs, apéritifs (e.g. vermouth, bitters), soft drinks including cola, juice, citrus, citrus fruit peel, marmalade, tomatoes and tomato-containing products, Mexican and Italian foods with red sauces, ketchup, spices (e.g. cloves, Jamaica pepper (allspice), cinnamon, nutmeg, paprika, curry, anise, and ginger), chili sauce, barbecue sauce, chutney, pickles, pickled vegetables, chocolate, vanilla, baked goods and pastries, pudding, ice cream, chewing gum, and candy.
Egg Anaphylaxis, sometimes flatulence and vomiting
Fish or shellfish[1] Anaphylaxis, sometimes vomiting Hazard extends to exposure to cooking vapors, or handling.
Fruit Mild itching, rash, blisters at point of oral contact Mango, strawberries are common problems
Garlic Dermatitis, asymmetrical pattern of fissure, thickening/shedding of the outer skin layers,[2] anaphylaxis
Hot peppers Skin rash, hives, throat tightness, tongue swelling, possible vomiting
Oats Dermatitis, respiratory problems, anaphylaxis
Meat[3] Dermatitis, rarely anaphylaxis Allergies to the sugar carbohydrate found in beef, lamb, and pork called alpha-gal. It is brought on by tick bites.[4][5]
Milk[1] Skin rash, hives, vomiting, diarrhea, constipation, stomach pain, flatulence, nasal congestion, dermatitis, blisters, anaphylaxis Not to be confused with lactose intolerance.[6]
Peanut[7] Anaphylaxis and swelling, sometimes vomiting Includes some cold-pressed peanut oils. Distinct from tree nut allergy, as peanuts are legumes.
Rice Sneezing, runny nose, itching, stomachache, eczema. People with a rice allergy can be affected by eating rice or breathing in rice steam.
Sesame Possible respiratory, skin, and gastrointestinal reactions which can trigger serious systemic anaphylactic responses.[8][9] By law, foods containing sesame must be labeled so in European Union, Canada, Australia, and New Zealand.[8]
Soy Anaphylaxis, sometimes vomiting
Sulfites Hives, rash, redness of skin, headache (particular frontal), burning behind eyes, breathing difficulties (anaphylaxis)
Tartrazine Skin irritation, hives, rash Synthetic yellow food coloring, also used for bright green coloring
Tree nut[10] Anaphylaxis, swelling, rash, hives, sometimes vomiting Hazard extends to exposure to cooking vapors, or handling. Distinct from peanut allergy, as peanuts are legumes.
Wheat[11] Eczema (atopic dermatitis), Hives, asthma, hay fever, angioedema, abdominal cramps, Celiac disease, diarrhea, temporary (3 or 4 day) mental incompetence, anemia, nausea, and vomiting[12] Not to be confused with Celiac Disease or NCGS (Non Celiac Gluten Sensitivity). While wheat allergies are "true" allergies, Celiac Disease is an autoimmune disease.[13]

Present in many drugs, such as hemorrhoid suppositories and ointment (e.g. Anusol), cough medicine/suppressant and lozenges, diaper rash ointments, oral and lip ointments, tincture of benzoin, wound spray (it has been reported to inhibit Mycobacterium tuberculosis as well as the common ulcer-causing bacteria H. pylori in test-tube studies), calamine lotion, surgical dressings, dental cement, eugenol used by dentists, some periodontal impression materials, and in the treatment of dry socket in dentistry.

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.[26][27]
Pollen Sneezing, body ache, headache (in rare cases, extremely painful cluster headaches may occur due to allergic sinusitis; these may leave a temporary time period of 1 and a half to 2 days with eye sensitivity), allergic conjunctivitis (includes watery, red, swelled, itchy, and irritating eyes), runny nose, irritation of the nose, nasal congestion, minor fatigue, chest pain and discomfort, coughing, sore throat, facial discomfort (feeling of stuffed face) due to allergic sinusitis, possible asthma attack, wheezing
